Acoustech H-100II Manuale utente

Congratulations on your purchase of a H-100II powered subwoofer. It will give your stereo system unparalleled low frequency output!

Bass frequencies are critical to realistic sound reproduction. After you’ve hooked up your H-100II, you will discover just how much

punch and depth you’ve been missing. No matter what kind of music or videos you listen to… whether you listen to them loud or soft,

you will experience sound that is richer and fuller. Bass guitar and string bass will have more impact. You will be able to FEEL as well

as hear percussion – just the way you would at a live performance. If you have an audio/video system, movies will come alive with

thunderous sound effects that were never possible without the H-100II.

This manual will take you step-by-step through the setup and operating process of your H-100II. Reading this manual carefully will

ensure you get maximum performance from your H-100II.

UNPACKING

Remove the H-100II carefully from its carton to prevent any scuffing or scratching. Take a moment to inspect for any shipping damage.

If you discover shipping damage, please contact your dealer and the shipping company immediately.

Please make sure to keep your sales receipt, it will establish the duration of your warranty.

PLACEMENT

Placement is extremely important because it dramatically affects the bass quality. An optimally placed subwoofer is much more pow-

erful and nice sounding than a poorly placed one. Three factors need to be considered:

1) Distance from your main speakers – The best placement for your subwoofer is on the same wall as the main speakers. How-

ever, if you are not able to place your subwoofer on the same wall as your main speakers, avoid placing the subwoofer halfway

between the front and back walls. This is where you get a strong null from your room’s standing waves. No matter how powerful the

subwoofer is, there will not be as much bass around the center of the room.

2) Distance from a wall outlet – Since the subwoofer requires AC power, it must be placed within 10 feet of a wall outlet. We

don’t recommend extending that range with an extension cord.

3) Positioning and Proximity to walls and corners – Physical placement of the subwoofer will have a definite impact on the

frequency response and the perceived amount of subwoofer bass output. Because low frequencies have long wavelengths, they are

influenced by proximity to a boundary such as a wall or floor.

(See Drawing A below) When you place the subwoofer well away from a wall, it will produce bass at a certain level. Move the

subwoofer close to the wall, it will produce more output (about 3dB more). Putting the subwoofer in a corner will increase output

another 3dB (6dB more than when placed away from walls and corners). The main thing to remember is you can place your subwoofer

in many areas of your room dependent on how much bass you want. If you like a lot of heavy bass, put the subwoofer into a corner.

If you like smoother, less obvious bass, move the subwoofer out into the room.

Since low bass waves are very large (up to forty feet or more across!), they tend to cancel and reinforce each other, causing places

in the room where there are lots of bass and other places where there isn’t very much bass at all. To locate the best place in your

room to put your subwoofer, you can use a technique called the “subwoofer crawl”. First place the subwoofer where you will be

sitting (ex. couch or chair) in your listening area. Turn on music with steady/constant bass and walk around the room at/near knee

level until you find the place where the bass sounds most accurate and balanced. This is where the subwoofer should be placed.

1. POWER INDICATOR LED – When the subwoofer is ON, this LED light will be green. When the subwoofer is

in the STANDBY mode, it will be red.

2. POWER/AUTO ON SWITCH – This toggle switch turns the subwoofer on and off. When the switch is in the

OFF position, the subwoofer will not play. When the switch is in the ON position, the subwoofer will stay on

at all times. When the switch is in the AUTO position, the subwoofer will automatically come on when bass

frequencies are fed to it. Then after around 15-20 minutes after you stop playing music, the subwoofer will

automatically go into STANDBY mode until more bass frequencies are fed to it. STANDBY mode uses very

little electricity.

3. PHASE SWITCH – This switch is used to set the subwoofer’s phase to either normal “0º” or reverse “180º”

(out of) phase. The physical location of your subwoofer and main speakers determines the phase setting that

will sound best at your main listening position. Once you determine the placement of the subwoofer, you will

need to try both positions of this switch to determine which setting sounds better in your room. If this requires

using the “180º” mode, don’t worry, there is nothing “abnormal” about it.

4. VOLUME CONTROL – Rotating this knob clockwise increases the output level of the subwoofer. To start

out, make sure that the VOLUME is turned all the way down (fully counterclockwise). Then, slowly adjust the

volume to blend with the other speakers in your system. Care should be taken not to overdrive the subwoofer

to the point of audible distortion.

5. CROSSOVER FREQUENCY CONTROL – If you are connecting your subwoofer to a Dolby Digital type

receiver which has a low level SUBWOOFER or LFE output that requires a subwoofer cable for connection,

you will adjust and set your subwoofer crossover through your receiver, not by using this control. Please check

your receiver owner’s manual for instructions.

If your receiver is not digital (example: stereo only integrated amp or older Dolby Pro Logic receiver) and/or you

are using the HIGH LEVEL INPUT speaker connections, you will use this control to set your crossover in your

subwoofer. This control determines what lower part of the frequency spectrum will be reproduced by the sub-

woofer and what higher parts will be handled by your main speakers. It is a “crossover” control. Rotating the

knob sets the point where all lower frequencies will be handled by the subwoofer and all higher frequencies

will be routed to your main stereo speakers. As a starting point, if you are using left and right tower speakers,

set the CROSSOVER FREQUENCY CONTROL to 80 Hz, with bookshelf speakers to 100 Hz, and with small mini

speakers to 120 Hz.

6. SUB RCA INPUT – This jack is used with a cable to connect your subwoofer to your receiver. This is the

preferred connection. If you use this connection, you will not use #10 and #11.

7. CROSSOVER FROM DIGITAL RECEIVER OR SUB SWITCH – If you are using a Dolby Digital receiver

which has a low level SUBWOOFER or LFE output that requires a subwoofer cable for connection, set this switch

to “Digital Receiver” so you can adjust your subwoofer crossover through your receiver. If your receiver is not

digital (example: older Dolby Pro Logic receiver or stereo only integrated amp) and/or you are using the HIGH

LEVEL INPUT speaker connections, set this switch to “Pro Logic Receiver” so you can adjust your crossover

through your subwoofer.

8. POWER INPUT – This connector is the AC power “in” for the power cord which is supplied with your

H-100II.

9. REMOVABLE FUSE HOLDER – By pushing in and turning counter-clockwise, you can remove and replace

the fuse. Use only the correctly rated 5 x 20 mm, 1.6 amp 250-volt replacement fuses.

10. OUTPUT TO SPEAKERS – If your receiver does not have a SUBWOOFER or LFE output, use these color

coded binding posts to run speaker wire from your main left and right speaker terminals to these OUTPUT

TO SPEAKER terminals. Note: These cannot be used in conjunction with SUB-IN low level inputs (See #6).

11. HIGH LEVEL INPUTS FROM AMPLIFIER – If your receiver does not have a SUBWOOFER or LFE

output, use these color coded binding posts to run speaker wire from your receiver’s main left and right

speaker terminals to these HIGH LEVEL INPUTS.

SUBWOOFER CONNECTION - METHOD A

Connecting to Receivers with a SUBWOOFER or LFE Output Jack

All Dolby Digital, DTS, THX, and Bass Management equipped receivers have a low level SUBWOOFER or LFE output jack. If you

have this, you will use the METHOD A connection as shown below in Drawing C. This is the recommended and easiest connection.

If your receiver does not have a low level SUBWOOFER or LFE output jack, you will use METHOD B (Drawing D) on Page 7 to

connect your subwoofer to the receiver.

For this connection, you will need a mono interconnect cable with a male RCA jack on both ends. This can be purchased at the

majority of electronics and audio stores. Make sure the length of your cable is long enough to reach from your receiver to your sub-

woofer location. The cable should lie flat with a little bit of slack to give some placement flexibility.

WIRELESS HOOKUP - If you prefer a wireless connection rather than using a subwoofer cable, you can connect your

H-100II wirelessly to your digital receiver with a BIC WTR-SYS kit. You can also add an unlimited amount of wireless H-100II

subs to your system by adding BIC W-Receivers. Please contact BIC sales at 877-558-4242, ext. #1 for more information.

HOOKUP STEPS

1. IMPORTANT: Make sure that ALL stereo

system components including the subwoofer

are turned OFF before proceeding.

2. Locate the SUBWOOFER or LFE output

connector on the rear of your receiver and

connect one end of the RCA cable to it.

3. Route the RCA cable to the subwoofer lo-

cation (trying to minimize areas where it

may be stepped on). Connect the other end

of the cable directly to the SUB IN.

4. Connect your main (and surround speak-

ers if applicable) to the receiver according

to the receivers owner manual.

5. Connect the included power cord to the

POWER INPUT (#1) on the back of your

H-100II. Then connect its plug to an AC

outlet ONLY. Since your H-100II draws a

moderately high amount of current, we do

not recommend plugging it into a “conve-

nience” outlet (switched or unswitched)

found on the back of receivers and other

stereo components.

6. Set the CROSSOVER FROM DIGITAL

RECEIVER OR SUB SWITCH (#2) to the

“Digital Receiver” position (on left). This will

enable you to set the crossover from your

digital receiver and disable the CROSS-

OVER FREQUENCY CONTROL (#3) on

the back of your H-100II (also see Page 5,

#5). Refer to your receiver’s owner manual

for instructions on how to set your crossover.

You also need to make sure the SUB-

WOOFER ON setting is set in your receiver.

Otherwise, the receiver will send no signals

to the subwoofer and there will be no sound.

7. Set the PHASE SWITCH (#4) to 0°.

You will later need to follow instructions on

Page 5, #3 for room settings.

8. You are now ready to turn your POWER

SWITCH (#5) on and enjoy the deep bass

you have been waiting for. You can learn

more about the “auto” feature on this switch

on Page 5, #2.

9. See Page 9 for “Initial Listening Test”.

SUBWOOFER CONNECTION-METHOD B

Connecting to Receivers with NO SUBWOOFER or LFE Output Jack

If your receiver does not have a low level SUBWOOFER or LFE output jack (for example, older Dolby Pro Logic receivers or

stereo-only integrated amps), you will use the method shown below in Drawing D to connect your subwoofer to the receiver.

For this connection, you will need speaker wire to run from your receiver to sub (for subwoofer HIGH LEVEL INPUTS), and then

from the sub to speakers (for OUTPUT TO SPEAKERS). Speaker wire can be purchased at the majority of electronics and audio

stores. We recommend 16-18 gauge wire. The lower the number gauge, the thicker the wire is. For longer runs, use thicker

wire. Make sure the length of your wire is long enough to give a little bit of slack to for some placement flexibility.

HOOKUP STEPS

1. IMPORTANT: Make sure that ALL stereo

system components including the subwoofer

are turned OFF before proceeding.

2. Measure the length of wire you will need,

and then cut and strip ½˝ of the insulation

from each end of the four wires you will run

for hookup.

3. Locate the front left and right main speak-

er terminals on the rear of your receiver and

connect two wires to these terminals.

4. Route the speaker wire to the subwoofer

location (trying to minimize areas where it

may be stepped on). Connect the other ends

of the speaker wire directly to the HIGH

LEVEL INPUTS FROM AMPLIFIER #1.

Make sure the left and right wires are hooked

to the proper left and right channel and that

all (+) terminals go to (+) terminals and all (-

) terminals go to (-) terminals. Most speaker

wire has some marker to help you keep track

of the polarity such as color coding or writing.

5. Connect the two remaining speaker wires

from OUT TO SPEAKERS #2 to your main

left and right speakers. As in step 4 above,

make sure the left and right channels and (+)

and (-) polarity are correct.

6. Connect the included power cord to the

POWER INPUT (#3) on the back of your

H-100II. Then connect its plug to an AC

outlet ONLY. Since your H-100II draws a

moderately high amount of current, we do

not recommend plugging it into a “conve-

nience” outlet (switched or unswitched)

found on the back of receivers and other

stereo components.

7. Set the CROSSOVER FROM DIGITAL

RECEIVER OR SUB SWITCH (#4) to the

“Pro Logic Receiver” position (on right). This

will enable you to set the crossover from your

subwoofer with the CROSSOVER FRE-

QUENCY CONTROL (#5) on the back of

your H-100II (also see Page 5, #5). In most

cases, setting the crossover to the 90Hz set-

ting on the control will yield the best results.

8. Set the PHASE SWITCH (#6) to 0°.

You will later need to follow instructions on

Page 5, #3 for room settings.

9. You are now ready to turn your POWER

switch (#7) on and enjoy the deep bass

you have been waiting for. You can learn more about the “auto” feature on this switch on Page 5, #2.

INITIAL LISTENING TEST

It’s now time to test the H-100II subwoofer in your listening environment.

1. Before turning your stereo system and subwoofer on, double-check all connections.

2. Turn the volume controls on both the subwoofer and your audio receiver all the way down (fully counterclockwise)

and check that the PHASE SWITCH is set to 0° and CROSSOVER FROM RECEIVER OR SUB SWITCH is set to the

proper setting (see Page 5, #7).

3. Turn your stereo system and then subwoofer to the ON position by using the POWER AUTO-ON SWITCH. (See

details on Page 5, #2 regarding AUTO position after performing the “Initial Listening Test”).

4. Confirm that the subwoofer’s green POWER INDICATOR LED is glowing. If it isn’t, check the power connections

between the subwoofer and the wall outlet.

5. Play a musical selection that you are familiar with. Pick a song that has regular low bass beats. Advance the audio

receiver’s volume control up to a normal listening level. If you don’t hear sound through your main speakers, turn off

the system and check connections. Also consult the troubleshooting tips.

6. If sound is coming out of your main speakers, slowly turn the sub amp’s VOLUME CONTROL clockwise until you

hear noticeable additional bass. If you don’t hear bass by the time you have advanced the subwoofer’s VOLUME CON-

TROL halfway, turn off the system and check connections. Also consult the troubleshooting tips.

7. Adjust the sub amp’s VOLUME CONTROL until you are satisfied with the amount of bass (care should be taken not

to overdrive the subwoofer to the point of audible distortion). You may want to try several different movies, tapes, com-

pact discs or DVDs while determining how high to adjust the volume. The amount of bass will vary from disc to disc

and between different types of music.

8. Now that you have adjusted the quantity of bass through the volume, it’s time to work on the quality of the bass by

experimenting with subwoofer placement in your room and adjusting the crossover and PHASE SWITCH.

a. Subwoofer Placement (Also See Page 3 “Placement”) – Subwoofer placement is extremely important because

it dramatically affects the bass quality. An optimally placed subwoofer is much more powerful and nice sounding than

a poorly placed one. While playing music, move the subwoofer around, in and out of corners, closer and farther from

the wall, etc. – as much as the power cord or other connections will allow to determine the best placement. You may

also want to try the “subwoofer crawl” technique found in the last paragraph of “Placement”, Page 3.

b. Crossover – If you have hooked your subwoofer to a Dolby Digital, DTS, THX, or Bass Management receiver, you

will need to refer to your receiver’s user manual for instructions on how to adjust and set your subwoofer crossover

from the receiver.

If your receiver is not digital (example: older Dolby Pro Logic or stereo-only integrated amp) and/or you are using

the HIGH LEVEL INPUT speaker connections, you will use the CROSSOVER FREQUENCY CONTROL on the back

of your subwoofer’s amp to set your crossover from your subwoofer. Change the CROSSOVER FREQUENCY CON-

TROL to higher and lower settings. If the crossover frequency is set too high, you’ll start to hear low midrange

(voices and instruments) through it. This will negatively affect the stereo imaging of your main speakers. If this

occurs, lower the crossover frequency setting until you hear only bass from the subwoofer. If the crossover frequency

is set too low, you simply won’t get much output from the subwoofer. As a starting point, if you are using left and

right tower speakers, set the CROSSOVER FREQUENCY CONTROL to 80 Hz, with bookshelf speakers to 100 Hz, and

with small mini speakers to 120 Hz.

c. PHASE SWITCH – Have someone change the PHASE SWITCH back and forth from 0º to 180º while you sit in

the main listening position. Leave the switch in the position where bass sounds most accurate and balanced.

9. After you are satisfied with the output of your subwoofer, you can make all your volume settings through your

receiver’s volume control. The only time you might want to re-adjust the subwoofer amp’s VOLUME CONTROL

is when you encounter a musical selection that has abnormally low – or high – bass.

10 TROUBLESHOOTING GUIDE

If you are having a problem with your subwoofer, please read through this “Trouble Shooting Guide”. Many times problems

are actually caused by other items in the system or the subwoofer’s interaction with those items. These problems can easily

be resolved with this guide.

Problem Cause Solution

You have a Ground Loop or prob-

lem with other equipment. This

causes the vast majority of hum

related complaints. The electrical

grounds of the components in

your system are not at the same

electrical potential.

A very common ground loop source is cable TV or satel-

lite cabling. Very few installers take the time to ground

the cable to the house ground, causing a 60 Hz hum that

the subwoofer reproduces. Disconnect the coaxial cable

from your TV or cable box. If the hum goes away, the

cable is the cause. In that case contact your cable com-

pany or get an inexpensive 75 ohm ground loop isolator

on line or at a local electronics store. Ground loops can

also come from faulty electrical wiring in your home.

Consult a licensed electrician to evaluate and possibly re-

pair the AC wiring in your home.

• It is possible that some cables have a poor or broken

ground due to poor construction, oxidation, or damage.

Also, poorly shielded cables can potentially pick up noise.

Try another cable or speaker wire. Also, move the signal

cable away from AC cables, power transformers, or other

EMI sources.

You have an amplifier problem. • Disconnect all interconnects from the amplifier. If still

hums, call or email technical support.

A light dimmer or other triac

based (SRC) device is on the

same AC circuit.

Your speaker wires or intercon-

nects are the cause.

• Use an AC line filter or plug the unit into a different cir-

cuit.

• The unit is going into STANDBY mode during the quiet

passages. Try turning the source signal up. On a Dolby

Digital receiver, turn the SUBWOOFER level up in the

SPEAKER SET-UP menu. After you turn the signal up, turn

down the volume knob on the subwoofer to compensate.

• An alternative is to turn the subwoofer ON/AUTO/OFF

switch to the ON position. When playing, it does not use

any more power and does not affect reliability.

• Check to see if the crossover through the receiver is set

too low, or if setting crossover from the sub, check to see

if the crossover set through the sub is set too low. This

will greatly reduce the signal going to the sub and hence

make it go into STAND BY MODE.

The source is not providing

enough signal.

Noise is being generated by

upstream equipment.

• When you shut down your equipment, turn off the sub-

woofer first. When powering up, turn on the subwoofer

last.
