1. INTRODUCTION

In purchasing the BEHRINGER POWERPLAY PRO 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 POWERPLAY PRO 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 POWERPLAY PRO 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 POWERPLAY PRO 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.

1. INTRODUCTION 5

POWERPLAY PRO HA4600

If the unit is damaged, please do not return it to us, but notify your dealer and the shipping company immediately, otherwise claims for damage or replacement may not be granted.

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

+

Before connecting the POWERPLAY PRO to the mains, please carefully check that your equipment is set to the correct supply 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 apply to export 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 properly. For your own safety, you should never remove any ground connectors from electrical devices or power cords or render them inoperative.

WARNING!

+

It should be pointed out, that extreme output volumes may damage your ears and/or your headphones. Turn down all LEVEL controls before you switch on the unit. Always pay attention to an appropriate volume.

2. CONTROL ELEMENTS

The BEHRINGER POWERPLAY PRO 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 panel control elements

1 The DIRECT IN socket is used to apply external signal sources. Use of this input automatically cuts off the MAIN signal applied on the rear panel.

2 The INPUT LEVEL control adjusts the sound level of the input signal, which is fed in via the rear panel

MAIN INPUT socket.

1. INTRODUCTION

POWERPLAY PRO HA4600

3 The 4-digit INPUT 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.

4 The HEADPHONE OUT 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.

5 A further input signal can be mixed in to the MAIN or the DIRECT IN-Signal via the AUX IN-input.

6 The L MUTE switch mutes the left input signal.

7 The R MUTE switch mutes the right input signal.

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

9 The 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 DIRECT IN signal and the input signal, which was applied to the AUX input.

12 The OUTPUT 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 OUTPUT 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.

2.2 The rear panel control elements

2. CONTROL ELEMENTS 7

POWERPLAY PRO HA4600

3. APPLICATIONS

3.1 Using the MAIN inputs

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

POWERPLAY PRO 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 inputs

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 POWERPLAY PRO 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 POWERPLAY PRO 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 BEHRINGER

8 3. APPLICATIONS

POWERPLAY PRO HA4600

POWERPLAY PRO 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 input

The DIRECT 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

DIRECT 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 headphones

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.

3. APPLICATIONS 9

POWERPLAY PRO HA4600

4. AUDIO CONNECTIONS

As a standard, the BEHRINGER POWERPLAY PRO 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 persons install and operate the POWERPLAY PRO. During installation and operation the user must have sufficient electrical contact to earth.

Electrostatic charges might affect the operation of the unit.
