1. INTRODUCTION

In purchasing the BEH INGE POWE PLAY P O HA4600 you have acquired a headphone amplifier of the

high end-class. The equipment was developed for the most demanding uses: professional recording, radio and

TV studios, CD and digital production equipment etc. Its extensive capabilities make the POWE PLAY P O

universally applicable. It was developed for use both as a reference unit, to assess the quality of a final mix, and

as a distribution amplifier for the comfortable addition of playbacks in studio use.

The POWE PLAY P O has a range of switching possibilities and a sound performance, which are found in

few headphone amplifiers. Besides its extremely powerful amplifiers the HA4600 also has an ingenious

signal-source distribution system.

Improving on the well-known POWE PLAY P O unit was a big challenge. We are proud that we have been

able to develop further the innovations we introduced in the preceding models and to have developed an even

more high-value headphone amplifier, which can meet professional expectations in every type of application.

The HA4600 includes for example bass and high-EQ in each channel, making possible an even more

individualized audio setup. An 8-segment LED display gives you exact information on the performance of each

channel and makes it possible to control the level precisely, at any time.

+This manual first describes the terminology used, so that you can fully understand the

POWERPLAY PRO and its functions. Please read the manual carefully and kee it for future

reference.

1.1 Before you begin

The POWE PLAY P O was carefully packed in the factory, in order to ensure safe transport. Nevertheless,

should the box show signs of damage please check the equipment itself immediately for any signs of external

damage.

Please also take the time to complete and return the warranty card within 14 days of the date of purchase,

otherwise you will lose the right to the extended warranty. Or simply use our online registration under

1. INT ODUCTION

+If the unit is damaged, lease do not return it to us, but notify your dealer and the shi ing

com any immediately, otherwise claims for damage or re lacement may not be granted.

Shi ing claims must be made by the consignee.

Be sure that there is enough space around the unit for cooling and please do not place the POWE PLAY P O

on high-temperature devices such as power amplifiers, etc. to avoid overheating.

+Before connecting the POWERPLAY PRO to the mains, lease carefully check that your

equi ment is set to the correct su ly voltage!

The fuse holder on the female mains connector has 3 triangular markings. Two of these triangles are opposite

each other. The HA4600 is set to the operating voltage shown next to these markings. It can be set to another

voltage by turning the fuse holder through 180°. CAUTION: this does not a ly to ex ort models, which

were designed e.g. only for a mains voltage of 120 V!

Connection to the mains is made by means of a mains cable with an IEC receptacle which complies with the

appropriate safety regulations.

+Please note that all units must be grounded ro erly. For your own safety, you should never

remove any ground connectors from electrical devices or ower cords or render them

ino erative.

WARNING!

+It should be ointed out, that extreme out ut volumes may damage your ears and/or your

head hones. Turn down all LEVEL controls before you switch on the unit. Always ay

attention to an a ro riate volume.

2. CONTROL ELEMENTS

The BEH INGE POWE PLAY P O has four identical channels. Each channel has three illuminated

push-button switches, four rotary controls, two jacks and eight LEDs. The common main section has one

control, one jack and five LEDs.

2.1 The front anel control elements

2. CONT OL ELEMENTS

3The 4-digit INP T LEVEL display shows the input level over a range from -24 to +12 dBu. The ON LED

lights up when you switch on the HA4600.

4The HEADPHONE O T socket is connected in parallel with the output sockets on the rear panel and

provides an additional means of listening to the individual channels. This function is particularly useful

when the equipment has been permanently installed in a rack.

5A further input signal can be mixed in to the MAIN or the DI ECT IN-Signal via the A X IN-input.

6The L M TE switch mutes the left input signal.

7The R M TE switch mutes the right input signal.

8The MONO switch can be used to switch each of the amplifiers from stereo to mono operation.

9The BASS control can be used to increase or decrease the lower frequencies (+/-15 dB).

10 The TREBLE control can be used to increase or decrease the higher frequencies (+/-15 dB).

11 The BALANCE control sets the ratio level between the MAIN or DI ECT IN signal and the input signal,

which was applied to the AUX input.

12 The O TP T LEVEL control is used to set the sound level of each individual amplifier. At the same time

it also controls the left and right channels.

13 The 8-digit O TP T LEVEL display monitors the output level of each individual channel over the range

from -24 to +12 dBu. If the Clip-LED lights up, please reduce the gain of the current channel, otherwise

distortion may result.

3. APPLICATIONS

3.1 Using the MAIN in uts

Connect a program source to the rear panel MAIN inputs and connect the headphone cable with one of the

POWE PLAY P O outputs. Turn the INPUT LEVEL and the BALANCE controls to their central positions. The

INPUT LEVEL control is used to increase or decrease together the volume of all the headphones which are

being controlled via the MAIN inputs. The individual OUTPUT LEVEL controls are only used to adjust the

desired channel volume.

3.2 Using the AUX IN in uts

The AUX IN inputs are basically used to mix in an additional input signal with the master signal, while the

corresponding BALANCE control adjusts the volume ratio between the two signals. The Aux function replaces

the monitor mixer which was necessary up to now, and so allows for a type of use which occurs frequently in

practice.

Suppose e.g. that a singer has to add a vocal track to an existing playback. Up till now it was usual for the

singer to listen to the playback by pressing a headphone pad against one ear, while using the other ear to

control his/her own voice. With the POWE PLAY P O this application becomes much simpler and much

more comfortable. The playback signal is played in via the MAIN IN inputs and the pre-amplified vocal signal

added via the AUX connector. The associated BALANCE control is adjusted so that the singer hears a perfect

sound volume mix of both the playback and the vocals, with the OUTPUT LEVEL control determining the

overall volume level.

The four independent channels permit the separate recording and mixing for four musicians. Should this not be

enough, you can interface and link as many POWE PLAY P O machines as desired using the MAIN OUT

outputs.

Fig. 3.1: Example of a playback application in a studio

In addition to the joint control of all channels via the MAIN input, each of the four amplifiers can also be used

completely independently. The AUX IN inputs are used here, together with the BALANCE controls. When the

BALANCE control is set fully counterclockwise (AUX position) the MAIN signal is suppressed and only the

input signals set up via the AUX IN input are fed through to the appropriate power amplifier. By using each

amplifier separately you can now play in up to four independent stereo programs. This means that you can play

in different, individual mixes for four musicians at the same time. As with a stage monitoring system you then

have the advantage of being able to play a specific configuration of instruments for each musician, giving him a

musically inspiring mix; or you can (e.g.) in a conference system set up different signal paths for the interpreters.

Create sub-groups, or set up premixes using the effects and monitor facilities of your mixing console. To do

this, turn the BALANCE control fully counterclockwise and connect the AUX inputs of the BEH INGE

POWERPLAY PRO HA4600

3. APPLICATIONS

POWE PLAY P O with the appropriate monitor-, subgroup or single outputs from the mixing console. Please

note that the AUX inputs are set up for stereo. To play in a stereo signal you will need a stereo jack. If you use

a mono jack it is advisable to activate the MONO switch, so as to get a signal distribution over both halves of

the headphone.

Fig. 3.2: Example of a monitor recording in stage use

3.3 Using the DIRECT IN in ut

The DI ECT IN socket is situated on the left side of the front panel. It is often necessary e.g. to replay a piece

of music to the musicians in the studio via a DAT recorder. This can be done simply and easily using the

DI ECT IN socket. Use of this input automatically blocks the signal set up over the MAIN IN socket.

3.4 Using the MONO function

For some monitor applications, especially in live operation, a stereo program can often sound irritating. This

negative effect becomes particularly clear if the two channels show a large channel separation, i.e. they have

different information content, linked with significantly different impressions of sound volume. The MONO switch

permits mono operation, that is, the linked operation of the left and right channels without having to use a Y

adaptor or a special cable.

3.5 Using the MUTE function

If the MONO switch is in the depressed position, the unit works in mono operation. Pressing one of the two

MUTE switches mutes the corresponding input signal (left or right input) and the non-muted signal can then be

heard over BOTH (left and right) headphone outputs. This routing option means that you can set up two different

programs via the left and right inputs and make just the one or the other audible as desired.

The Mute function is particularly useful if playback is to be combined with the simultaneous recording of a vocal

track. Whereas before it was necessary for a singer to hold one headphone pad away from his/her ear during

a music recording in order to hear his own voice better, with the HA4600 the playback can now be switched to

stereo mode and the unused channel switched to mute. The previous normaland uncomfortablepractice of

moving one headphone pad away from the ear is now a thing of the past.

3.6 Connecting several head hones

All four stereo amplifiers have three headphone output sockets on both the front and rear panels. This means

that several headphones can be connected via each amplifier at the same time, provided that the minimum

connection impedance of the amplifier does not drop below 100 Ohm. Since the amplifiers are resistant to

temporary short circuits, no damage will occur if the level drops below this impedance, but it can lead to a loss

of quality in the form of distortion and reduced performance.

4. AUDIO CONNECTIONS

As a standard, the BEH INGE POWE PLAY P O is equipped with electronically servo-balanced inputs

and outputs. The circuit design features automatic hum suppression for balanced signals and so ensures

trouble-free operation, even at the highest operating levels. Externally induced mains hum, etc. can therefore

be effectively suppressed. The automatic servo-function recognizes the presence of unbalanced connectors

and adjusts the nominal level internally to avoid level differences between the input and output signals

(6-dB correction).

+Please ensure that only qualified ersons install and o erate the POWERPLAY PRO. During

installation and o eration the user must have sufficient electrical contact to earth.

Electrostatic charges might affect the o eration of the unit.
