Dear Valued Customer

Thank you for choosing the Magnum Dynalab “

MD 208

” Discrete Audio Receiver.

Great care has been given to the design, manufacturing and selection of

components for the “

MD 208”

Discrete Audio Receiver. This complete process

insures optimum listening enjoyment for many years.

The FM Section is a special design completely researched and manufacturer in

house. In fact, we are the only company in the world that does their own R.F. front

end, choosing this practice due to the fact that no other manufacturer can produce

one that meets our very rigid performance specifications. These rigid specifications

insure that you can enjoy excellent FM reception regardless of signal conditions.

The Integrated Amplifier section of the

MD 208

is characterized by the simplicity of

the circuit. We use only high grade components, ensuring that accuracy and

realism of the music is the end result. The power supply with its specially designed

transformer is at the heart of the stability and dynamics that the

MD 208

exhibits.

When using these high grade components, a considerable length of time is required

for the

MD 208

to reach its full potential. Using either a high quality break-in disc or

white noise from a FM tuner will help ensure optimum performance as quickly as

possible.

Once again, thank you for including a MAGNUM DYNALAB product in your

entertainment system. We are sure that you will have years of listening pleasure

from your

MD 208

. Please be sure to register your product at

www.magnumdynalab.com, and if there is anything else we can do, please call us on

our toll free number, 1-800-551-4130, or contact us via email:

[email protected].

Respectfully yours,

Larry Zurowski

President

UNPACKING YOUR MD 208

Carefully inspect all sides of the shipping carton for damage. If there are marks or

holes in the carton make note of the location in relation to the unit inside. Any

obvious dents or scuff marks should alert you to the possibility of damage. Carefully

remove the MD 208 from the end caps and wrapping, inspect all sides. Pay special

attention to the corresponding areas on the unit where damage was found to the

shipping carton. If damage is evident, document the type and extent of the damage,

then repack the unit and call the dealer.

KINDLY DO NOT SEND THE UNIT BACK TO THE SHIPPER UNTIL YOU HAVE BEEN

ASKED TO DO SO.

DO NOT DISCARD THE PACKING MATERIALS AND CARTONS. Should there be a

necessity to return the unit for any reason, it must arrive safely and suitably

packaged in order for our receiver to accept it from the carrier. Also, if the unit has

incurred damage as a result of improper packaging, it is not likely that a claim for

the damage against the carrier will be successful.

Likewise, we will ship your unit back to you only in factory-approved packaging,

However, if the unit were to arrive at the factory on anything other than factory

approved packaging, we reserve the right to return same in factory-approved

packaging and charge the cost of the packaging to the shipper. This is the only way

we can assure you of a safe return (damage by carrier excepted).

SETTING UP THE MD 208

1. Position the receiver away from any spot which may have extremes in

temperatures.

2. Place the receiver on a very rigid surface capable of holding 50 pounds (22 KG).

3. The heat sinks on the side of the unit are used to keep the unit at a safe

operating temperature. It is important that they are not covered or the unit is not

installed in a closed area where there is little air circulation. Ensure at least 2” of

clearance on the left and right of the device, and 5” of clearance above the unit

to allow for proper ventilation. Further, keeping the heat sinks clean will maintain

the high level of efficiency for which they were designed. A soft cloth or

paintbrush works just fine to keep them clean.

4. Connect your FM antenna cable to the A1 ANTENNA IN terminal on the rear

panel of the tuner. The connector on the rear of the tuner is an “F” type (75

ohms). Should your antenna cable be the 300 ohm twin lead you may convert to

75 ohm using a 300 to 75 ohm balun/transformer. Make sure that the center

connector of the 75 ohm cable is properly inserted into the connector. If you do

not have an antenna now, prepare the temporary straight wire antenna that is

enclosed with the tuner. Connect one end into the center of the antenna input

connector on the rear of the tuner.

Please note that the piece of wire provided should only be used as a device to

test the tuner, to obtain optimum benefit from this fine tuner a better antenna

may be required. Magnum Dynalab offers a number of different antennas, these

antennas are discussed in the

Reception Techniques

in the back of the manual. If

you have any questions please call your dealer or Magnum Dynalab.

5. Unwrap the EIA AC cord and plug the EIA end into the rear socket marked

Power

Input

. Plug the other end of the AC cord into a 120/220/230/240 volt

continuous AC power supply. Be sure that the voltage marked on the rear of the

unit is the same as the AC source that you are using.

Note: Many countries that use 220/230/240 have a special FM transmitter,

deemphasis for these countries may be different. Please consult Magnum

Dynalab for the correct one.

SET UP OF THE INTEGRATED AMPLIFIER SECTION OF THE MD 208

(All numbers correspond to the product diagram on Page 11)

1. Now that you have positioned the MD 208 correctly and plugged it into the

appropriate AC power supply, you are ready to hook it up to the speakers. Hook

up your speakers to the receiver insuring that the positive (+) terminal on the

speaker is hooked up to the positive (+) output terminal on the receiver, likewise

that the negative (-) is correctly hooked up. Be sure that all the connections are

tightly affixed.

2. Located on the rear of the unit is a switch (beside the AC cord input). Turn it on

by depressing the top of the switch.

3. Turn the power switch on the front panel (2 on diagram) to the ON position. The

LED above the power switch will turn on, and center display will light up indicating

the selected source (i.e. Tuner, CD etc.).

SET UP OF THE TUNER SECTION OF THE MD 208

1. Set input (3 on diagram) to Tuner. The input display will show TU, the meters will

light up.

2. Press the stereo/mono button (5 on diagram) to S

tere

3. Press the bandwidth button

BW 1

button (6 on diagram), and LED will illuminate.

4. Press the M

ute

button (4 on diagram), and LED will illuminate. For normal

operation of the tuner, the mute switch should be off.

5. Press the

Signal Meter button

(8 on diagram), and LED will illuminate.

6. Turn the

Tuning Knob

until sound is heard, fine tuning the station using the

center tune meter and the signal strength meter as indicators. Check that the

Stereo

button’s LED is on when properly tuned to a strong frequency (as

indicated by the signal strength meter). Press the

Stereo

button again and this

will switch to

Mono

– the stereo light should go out. Switch back to S

tereo

– the

stereo light should come back on.

7. If you hear a crackling sound push the

Multi-path

button (8 on diagram). This will

switch the signal strength meter to indicate if the noise is a result of multi-path

(a difference in timing between the RF signal received by the tuner’s antenna and

the tuner itself). If the meter showcases even a moderate level of multi-path,

adjust the orientation of your antenna until multi-path signal reads zero. If the

- 7 -

needle on the tuner continually reads more than zero, move the antenna to a

different location or rotate the antenna. If this does not correct the problem, a

better or different antenna may be required, please see

Reception Techniques

the back of the manual.

8. You are now ready to listen and search for your favorite stations across the

frequency. If you encounter difficult reception situations please read the

Reception Techniques

section at the back of the manual.

Approximately 48 hours of “burn in” should eliminate any measure of drifting that

you may encounter with the tuner section of the MD 208. Please note that when

your receiver is turned off for more than a couple of hours, upon powering “ON”, you

may encounter a slight amount of drift on the station you were last tuned to (the

center tune meter is not perfectly aligned). Please do not touch the dial; when the

receiver warms back up, it will return to where it was last center tuned.

CONNECTING ADDITIONAL SOURCES TO THE MD 208

1. Using your RCA cables, plug the other source into one of the inputs marked in

the back of the receiver.

2. Set the input on the receiver to match the input on the rear of the unit that the

other source is plugged into.

3. With volume set to zero, power up the new source, initialize the playback, and

slowly adjust volume to desired level.

SET UP THE MD 208 WITH AN EXTERNAL HOME THEATER

PROCESSOR

The MD 208 is equipped with a unity gain input (A4 Input on the Pre-Amplifier

section). This is a switchable input, meaning the input can be used as a normal pre-

amplifier input or in unity gain mode.

To Connect to a Home Theater Processor

1. Turn the power off to the MD 208 by the main power switch on the rear of the

unit.

2. Connect your theater processor Main Left and Right interconnects into the MD

208 through the A4 input.

3. Connect your Main Left and Right speakers to the MD 208 speaker connections.

- 8 -

4. Power up the MD 208 by switching the main power rocker switch found on the

rear of the MD 208, to the “ON” position.

5. Press and HOLD the

“Input”

button (found on the faceplate of the MD 208) for at

least 3 seconds. A red LED above the input button will light, and this indicates

that the theater mode of input A4 is now active.

6. Input A4 is now the dedicated input for you to listen and control volume with your

home theater processor (Meaning that when you listen to regular music you use

the preamplifier found in the MD 208). Once input A4 has been activated into

Home Theater

mode, volume on input A4 will now be controlled via your external

processor preamp.

CAUTION

As standard practice, you should always turn off the main power to the MD 208

(found on the rear panel of the MD 208), whenever any source component,

interconnect or loudspeaker is being changed in your system.

Be aware, when activating

Home Theater

mode on input A4, the volume level on

input # 4 will be wide open. Please make sure that the RED LED above the input

button is not lit if a regular source is connected to input A4.

HOOKING UP A SUBWOOFER TO YOUR SYSTEM

1. Make sure your receiver is turned “OFF”.

2. Using RCA cables, connect one end to the

Pre Out

input marked on the rear of

the Receiver, the other end to your subwoofer.

3. Turn the subwoofer “ON”.

4. Turn the receiver on and adjust the volume level to suit you.

Please note the volume of the subwoofer is controlled by the volume control on the

receiver.

TAPE OUT LOOP

This is used if you wish to record the music you are listening to. Connect this to a

recordable peripheral source.
