1. INTRODUCTION
In purchasing the new POWERPLAY PRO HA4400, you have acquired a headphone amplifier of the high-end
class which meets all the demands and requirements of studio work. Due to its extensive functions and the
new design the POWERPLAY PRO is an extremely efficient and universal headphone amplifier. It has been
designed above all as a reference unit for the sonic evaluation of the final mix as well as a distribution monitor
amplifier for musicians in the studio.
The unit features switching possibilities and a sound quality few headphone amplifiers can offer. Apart from its
extremely powerful amplifiers the unit also offers a ingenious signal distribution system.
E
Advanced BEHRINGER Technology
Since its announcement of the first POWERPLAY several years ago, it has caused a sensation. This high-end
headphone amplifier is based on our many years of experience and discoveries in the field of professional
studio technology. The POWERPLAY finds widespread application throughout the world, in renowned studios,
sound reinforcement systems as well as in broadcast and TV studios.
The task to improve our famous POWERPLAY was a big challenge. We are very proud that we succeeded.
Compared to its predecessors, the POWERPLAY PRO offers several advanced features and we have suc-
ceeded in dramatically refining the audio qualities. The unit features now additional XLR input and output
connectors and LED displays for each channel, which give you exact information about the output gain.
Moreover, there is an input level meter, which helps you to set up the correct level.
State-of-the-art production processes
For the first time ever, the POWERPLAY PRO is now manufactured with SMD components (Surface Mount
Device). Using these sub-miniature components known from aeronautics does not only ensure extreme pack-
ing densities, but also improves the POWERPLAY PRO’s reliability.
The additional AUX input
In addition to its high-quality amplifiers, the POWERPLAY features a variety of professional switching and
mixing options: each of the four stereo amplifiers is equipped with an independent AUX input, which allows for
adding a further audio signal to the master signal. The musician can therefore control the volume of his/her own
instrument in the master playback signal as desired. This built-in mix function supersedes the external monitor
mixer required up to now.
The BEHRINGER distribution matrix
A extremely interesting feature is the intelligent and clearly arranged distribution matrix which allows each
channel to be switched over from stereo to mono whilst activating the mute function of the left and/or right input
signal source.
In mono mode, two different mixes can be fed into the left and right MAIN inputs on the rear panel. By muting
a channel, the signal of the channel which is not muted will appear on BOTH headphone pads. Thus, two
completely different mixes can be routed to the headphone set in mono mode.
In stereo mode, any muting action in a particular channel automatically mutes the corresponding headphone
output. As a consequence, it is possible to route the playback signal, for instance, to the left channel only, so
that the vocalist can hear his/her voice directly via the right channel of the headphones. So moving the unused
headphone pad away from the ear - uncomfortable but common practice up to now - will be a thing of the past.
MAIN output jacks are available to link several headphone amps, or to control external power amplifiers.
All power amplifiers are equipped with front and rear panel headphone outputs. Even if the unit is permanently
installed in a rack with fixed cabling, additional headphones can be connected without difficulties, which allows
for pre-monitoring the individual mixes for the musicians. Each power amplifier features three parallel output
connectors for the connection of up to three headphone sets per amplifier, or a maximum of 12 headphones per
unit.
The DIRECT IN input
A so-called DIRECT IN connector can be found on the front panel. For instance, it is often necessary to replay
a song for the musicians in the studio via a cassette recorder. This can be done easily and rapidly using the
DIRECT IN connector. When using this input, the master signal applied on the rear panel will be interrupted
automatically.

WARNING!
+
+
It should be pointed out, that extreme output volumes may damage your ears and/or your
headphone set. Turn down the LEVEL controls before you switch on the unit.
The following operational manual will introduce you to the BEHRINGER POWERPLAY PRO
and its various functions. After reading the manual carefully, make sure it is always on hand
for future reference.
2. THE DESIGN CONCEPT
2.1 High quality components and design
The philosophy behind BEHRINGER products guarantees a no-compromise circuit design and employs the
best choice of components. The operational amplifiers NJM4580 which are used in the POWERPLAY PRO,
are exceptional. They boast extreme linearity and very low distortion characteristics. To complement this
design the choice of components includes high tolerance resistors and capacitors, detent potentiometers and
several other stringently selected elements.
2.2 Inputs and outputs
2.2.1 Balanced MAIN inputs
As standard, the BEHRINGER POWERPLAY PRO is installed with electronically servo-balanced MAIN
inputs. The new circuit design features automatic hum and noise reduction for balanced signals and thus
allows for trouble-free operation, even at high operating levels. Externally induced mains hum etc. will 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 (correction
6 dB).
3. INSTALLATION
Your BEHRINGER POWERPLAY PRO was carefully packed in the factory and the packaging was designed
to protect the unit from rough handling. Nevertheless, we recommend that you carefully examine the packaging
and ist contents for any signs of physical damage, which may have occurred in transit.
+
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.
3.1 Rack mounting
The BEHRINGER POWERPLAY PRO fits into one standard 19" rack unit of space (1 3/4"). Please allow at
least an additional 4" depth for the connectors on the back panel. Be sure that there is enough air 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.
3.2 Mains voltage
Before you connect your POWERPLAY PRO to the mains, please make sure that your local voltage
matches the voltage required by the unit! The fuse holder on the female mains connector has 3 triangular
markers, with two of these triangles opposing each other. Your POWERPLAY PRO is set to the operating
voltage printed next to these markers, and can be set to another voltage by turning the fuse holder by 180°.
CAUTION: this instruction does not apply to export models exclusively designed, e.g. for 115 V
operation!

5. APPLICATION
5.1 Using the main inputs
Connect a program source to the rear panel MAIN inputs and connect the headphone cable to one of the
appropriate outputs. Turn up the INPUT LEVEL and the BALANCE controls to center position. The INPUT
LEVEL control is used to increase or decrease the general volume of all headphones controlled via the MAIN
inputs, while the individual OUTPUT LEVEL controls are used to adjust the desired channel volume.
5.2 Using the AUX IN inputs
Basically, the AUX IN inputs are used to add an additional input signal to the master signal, with the corre-
sponding BALANCE control determining the volume ratio between the two signals. The aux function supercedes
the previously required monitor mixer and allows for an application that is frequently used in practice.
Example: suppose a vocalist wants to record a vocal track that is to be added to already existing instrumental
tracks. Up to now, it has been common practice that the vocalist listens to the playback by pressing a
headphone pad against one ear, while controlling his/her own voice with the other – free – ear.
This kind of application can be achieved much more easily and conveniently with the POWERPLAY PRO.
The playback signal is inserted via the MAIN inputs, and the preamplified vocal signal is applied to the AUX
connector. The associated BALANCE control is adjusted so that the vocalist hears a perfect mix of both
backing tracks and vocals, with the OUTPUT LEVEL control determining the overall volume level.
Owing to the four independent channels of the POWERPLAY PRO, four individual mixes for four musicians can
be achieved. If this is not enough, you can interface and link any number of POWERPLAY PROs using the
MAIN outputs.

E
Fig. 5.1: Example of a studio playback application
5.2.1 Using the amplifiers as independent power amplifiers
In addition to the joint control of all channels via the MAIN input, each of the four power amplifiers can also be
used independently. The AUX IN inputs in combination with the BALANCE controls serve this purpose.
If the BALANCE control is set to its clockwise stop position (position “AUX“), the MAIN signal is muted; only
the input signals applied to the AUX IN input are routed to the power amplifier. By configuring the amplifiers as
completely independent power amplifiers, you can insert up to four independent stereo programme sources;
thus, four different and individual mixes for up to four musicians can be created. As with a stage monitor
system, you can give each musician a specific configuration of instruments and create a personal mix for him
or her that is musically inspiring. Or you can set up different signal paths for the interpreters in a conference
system.
Configure sub-groups or create pre-mixes using the effects and/or monitor facilities of your mixing console.
Fully turn up the BALANCE control and connect the AUX inputs of the BEHRINGER POWERPLAY PRO to the
corresponding monitor, sub-group or single outputs of the mixer.

5.3 Using the DIRECT IN input
The DIRECT IN connector can be found on the left side of the front panel. For instance, it is often necessary
to replay a song for the musicians in the studio via a cassette recorder. This can be done easily and rapidly
using the DIRECT IN connector. When using this input, the signal applied to the rear panel MAIN INPUT
connector is bypassed automatically.
Fig. 5.3: Playback via the DIRECT IN connector
5.4 Using the mono function
The MONO switch allows for mono operation, i.e., linked operation of the left and right channels, without
having to use a “Y-adapter“ or special cables.
In certain monitor applications, especially for live stage operation, a stereo programme may have a confusing
effect, so the conversion into a mono signal leads to better transmission quality. In particular, this negative
effect becomes obvious when the channel separation between the two channels is considerable, i.e., when
they contain different information with differing volume levels.
5.5 Using the mute function
The mute function of the individual input sources is a special feature of the BEHRINGER POWERPLAY PRO.
Depending on the position of the MONO switch, it offers two highly useful routing options:
5.5.1 The mute function in mono mode
When the MONO switch is pressed, the unit operates in mono mode. In this case, the two input signals are
combined and the resulting mono signal is fed into the left and right headphone outputs.
By pressing one of the two MUTE switches, the corresponding input source (left or right input) is muted and the
input signal which is not muted appears on BOTH headphone outputs (left and right). This routing option allows
for the selection of two different programmes which are fed into the left and right input by muting the unwanted
input source.
5.5.2 The mute function in stereo mode
The mute function is also very useful if playback is to be combined with simultaneous recording of a vocal
track. Up to now, vocalists have been forced to move one headphone pad away from the ear while recording, in
order to hear their own voice clearly.
Now, the BEHRINGER POWERPLAY PRO can mute the unused headphone channel in stereo mode. So
moving the unused headphone pad away from the ear - uncomfortable but common practice - will be a thing of
the past.

5.6 Connecting multiple headphones
All of the four stereo amplifiers feature one front and one rear panel headphone output connector. Multiple
headphones can be connected per channel, on condition that the resulting connection impedance does not fall
below 100 Ohms. As the power amplifiers are resistant to temporary short circuits, an impedance drop will not
cause any damage, however, it can affect the quality of reproduction, in terms of long-term damage and
distortion.
Additional headphones can be connected to the front panel headphone outputs, even if the unit is installed in
a rack with fixed cabling. If you wish to connect more than three headphones per amplifier, it is advisable to use
a split box or appropriate “Y“ cables. Please find additional information on how to connect the headphones in
chapter 3, and note that the minimum connection impedance of 100 Ohms is maintained.
