Congratulations! With the BEHRINGER POWERPLAY PRO,
you have acquired a high-end headphone amplifier. Both
POWERPLAY PRO units were developed with the most demanding applications in mind: professional recording, radio and
television studios, as well as CD/digital sound production. They
were developed as benchmark units for judging mixdown quality
as well as distribution amplifiers for flexible playback applications in studio environments.
Balanced inputs and outputs
Both BEHRINGER POWERPLAY PROs feature electronically
servo-balanced inputs and outputs. The servo function automatically recognizes when unbalanced pins are assigned. It
internally modifies the nominal signal level, thus preventing any
occurence of signal level difference between inputs and outputs
(6 dB correction).
My friends, it’s been worth the effort!
The following user’s manual is intended to familiarize
you with the unit’s control elements, so that you can
master all the functions. After having thoroughly read
the user’s manual, store it at a safe place for future
Thank you very much,
1.1 Before you get started
The POWERPLAY PRO was carefully packed at the assembly
plant to assure secure transport. Should the condition of the
cardboard box suggest that damage may have taken place, please
inspect the unit immediately and look for physical indications of
Uli Behringer
Damaged units should NEVER be sent directly to us.
Please inform the dealer from whom you acquired the
unit immediately as well as the transportation company
from which you took delivery of the unit. Otherwise, all
claims for replacement/repair may be rendered invalid.
1.1.1 Initial operation
2.1 Front panel
Please make sure the unit is provided with sufficient ventilation,
and never place the POWERPLAY PRO on top of an amplifier or
in the vicinity of a heater to avoid the risk of overheating.
Before plugging the unit into a power socket, please
make sure you have selected the correct voltage:
The fuse compartment near the power plug socket contains
three triangular markings. Two of these triangles are opposite
one another. The voltage indicated adjacent to these markings is
the voltage to which your unit has been set up, and can be altered
by rotating the fuse compartment by 180°. ATTENTION: This
does not apply to export models that were for example
manufactured only for use with 120 V!
If you alter the unit’s voltage, you must change the fuses
accordingly. The correct value of the fuses needed can
be found in the chapter “TECHNICAL DATA”.
Faulty fuses must be replaced with fuses of appropriate
rating without exception! The correct value of the fuses
needed can be found in the chapter “TECHNICAL DATA”.
Power is delivered via the cable enclosed with the unit. All
requiered safety precautions have been adhered to.
Please make sure that the unit is grounded at all times.
For your own protection, you should never tamper with
the grounding of the cable or the unit itself.
1.1.2 Warranty
Please take a few minutes and send us the completely filled
out warranty card within 14 days of the date of purchase. You
may also register online at The serial number
needed for the registration is located at the top of the unit. Failure
to register your product may void future warranty claims.
Fig. 2.1: Input section
The DIRECT IN socket is used to feed in additional stereo
signals. In the case of the HA4700, the signal brought in via
the DIRECT IN input has the same priority as the MAIN
signal. The HA8000 has a separate DIRECT INPUT
connector for each channel
(see fig. 2.3). In the case
of this model, the MAIN signal being fed in is automatically
interrupted when the said input is in use.
The MASTER LEVEL control governs the level of the input
signal that is fed through the MAIN INPUT connectors on
the back or through the DIRECT IN connector.
The HA8000 features two level controls (MAIN IN 1/
MAIN IN 2), so that two separately controllable input signals
can be connected. You select which of the two signals is
monitored by using the IN 1/IN 2 switches
in the
respective channel sections.
The 4-digit INPUT LEVEL display informs you about the
input level signal and diplays it in the range between -30
and 0 dB. When the unit is powered on, the ON LED lights
up. You achive the best input signal quality when its level is
at the highest level just before it starts distorting. The clip
LED should light up only during the highest signal peaks.
1.2 The user’s manual
This user’s manual has been written in such a way to enable
you an overview over the control elements of the unit and offers
at the same time detailed information about possible applications.
To facilitate quick look-ups, control elements have been described
in groups depending on their function. Should you need detailed
information about specific topics not covered in this manual,
please visit our website at For example,
additional information about power amps and effects processors
is found there.
We would like to bring your attention to the fact that
extremely loud sound levels may damage your hearing
as well as your headphones. Please lower all OUTPUT
LEVEL knobs leftwards before powering up the unit.
This chapter contains descriptions of various control elements
of your POWERPLAY PRO. All controls and connections are
discussed in detail. Additionally, useful advice about their possible
applications is also given.
The HA8000 has eight independent amplifiers for connecting
headphones, while the HA4700 has four. The latter has several
additional features not found in the HA8000 due to space
considerations. The differences between the two units are
explained in detail in the text sections that follow.
Fig. 2.2: Individual headphones amplifier sections
The 8-digit OUTPUT LEVEL display informs you about the
ouput signal level of each individual channel, and diplays it
in the range between -30 and 0 dB. When the clip LED
lights up, lower the amount of gain applied to the individual
channels to avoid distortion.
The BASS control (HA4700 only) attenuates or boosts the
low frequency portions of the signal (+/-12 dB).
The TREBLE control (HA4700 only) attenuates or boosts
the high frequency portion of the signal (+/-12 dB).
The L MUTE and R MUTE switches allow you to mute the
respective input signal, so that only the remaining input
signal is audible (HA4700 only).
The PHONES OUT connector is connected in parallel to
the output connectors
located on the rear, presenting
an easily accessible additional monitor option for individual
channels. This function is particularly helpful when the unit
is permanently installed in a rack.
The AUX IN input is used to mix an additional input signal
into the MAIN IN or DIRECT IN connectors (HA4700 only).
Should you want to use this option on a mono signal, we
recommend using the ST./2-CH. switch (position 2-CH,
depressed) in order to hear the signal in both ears.
Fig. 2.3: Mains supply, fuses compartment and
headphone outputs
The ST./2-CH. switch is used to alternate whether input
signals are audible in stereo (not depressed: ST.) or in mono
(depressed: 2-CH.) The HA8000 features a MONO switch
instead of a ST./2-CH. switch
Various input signals can be connected to the HA8000 by
utilizing a separate DIRECT IN connection for each amp
section, located on the rear. If a signal is fed into this
connector, both MAIN IN signals will be muted.
The BALANCE control (HA4700 only) regulates the stereo
image of input signals, provided that the AUX IN input of
one of the amp sections is not already in use. When the
AUX IN section already has a signal assigned to it, the
BALANCE control governs the ratio between MAIN IN
(DIRECT IN) and AUX IN signal.
These are the MAIN OUT connectors of the HA4700. The
respective jacks and XLR connectors are wired in parallel.
Via these connectors, you can link as many headphone
amps as desired to allow for connection of additional
headphones. The HA8000 has no MAIN OUT connectors.
To connect additional units on a per-need basis, you can
use HA8000’s PHONES OUTPUT connectors.
The HA8000 does not feature a BALANCE control.
Headphones volume of the individual amp sections is
regulated using the OUTPUT LEVEL control. Both the left
and the right channel are regulated simultaneously.
The POWER switch powers the POWERPLAY PRO on. You
should always make sure that the POWER switch is in the
“Off” position when initially connecting the unit to the mains.
Please take note: Merely switching the unit off does not
mean that it is fully disconnected from the mains. When
not using the unit for prolonged periods of time, please
unplug the unit’s power cord from the power outlet.
The MAIN IN 1 or MAIN IN 2 input signal is selected by
using the IN 1/IN 2 switch. When the DIRECT INPUT of the
channel has a signal assigned to it, you can hear the said
signal only (HA8000 only).
When you depress the MONO switch (HA8000 only), the
signal is played in mono. Singers in particular appreciate
this function because a mono signal is much less distracting
to listen to than a comparable stereo signal. A mono signal
makes spacial orientation during live performances easier.
2.2 Rear panel
Power is supplied via an IEC connector. The matching cable
is provided with the unit.
connecting the unit to a power outlet, please make sure
that the selected voltage matches your local voltage. When
replacing fuses, please make sure that you always use fuses
of the same type. Some units allow for switching between
230 V und 120 V. Please note: when connecting a unit
intended for the European market to a 120 V power outlet,
you must also replace the factory fuse with a higher-value
The HEADPHONE OUT connectors of the individual amp
sections are also used for connecting headphones
(HA8000: PHONES OUTPUT). The HA4700 features two
additional headphones connectors per channel located
on the rear; the HA8000 has one.
Fig. 2.4: MAIN IN and MAIN OUT connectors
The MAIN IN connectors of the HA4700 come as balanced
1/4" TRS and XLR connectors.
The HA8000 features only 1/4" TRS connectors for MAIN
3.1 Using the MAIN IN connectors
Connect a program source with the MAIN IN connectors located
on the rear, and connect your headphones to an amp section of
your choice. Set the MASTER LEVEL and BALANCE controls
(HA4700) in the center position. The MASTER LEVEL control is
used to lower or raise the volume level of all headphones which
receive signals via the MAIN IN inputs and/or the DIRECT IN
input. In the case of the HA8000, MAIN IN controls 1 and 2
regulate the input level of two separate input signals. The individual OUTPUT LEVEL controls are used for adjusting the desired
channel volume only.
3.2 AUX IN inputs (HA4700 only)
As a general rule, the AUX IN inputs are used to add an extra
input signal to the main signal, whereby the respective BALANCE
control regulates the relative ratio of those signals to one another.
This way, you can for example effortlessly record vocals and
feed in an already existing playback using your POWERPLAY
PRO-XL HA4700. The playback signal is fed through the MAIN IN
inputs, and the preamplified vocal signal is fed into the AUX IN
connector. The respective BALANCE control should be set up in
such a way that the singer gets a perfectly matched mix between
the playback and the vocals, whereby the OUTPUT LEVEL control
regulates the overall volume.
3.6 Connecting multiple headphones
The HA4700 features three headphones connectors altogether,
while the HA8000 has two. You can connect multiple headphones
to an amp simultaneously, provided that the minimal output load
impedance of the amp does not fall below 8 Ohms. In the case of
the HA8000, the minimal output load impedance is 100 Ohms per
When connecting two headphones, individual
headphones should not have impedance lower than
16 Ohms; when connecting three headphones,
individual headphones should not have impedance
lower than 24 Ohms (HA4700). When connecting two
headphones to the HA8000, the impedance of individual
headphones should not fall below 200 Ohms.
Even though going under the above mentioned minimal impedances does not cause deffective operation, you may experience
a quality loss audible as lowered performance and distortion.
Fig. 3.1: Playback application in a studio
In addition to the usage of all channels via the MAIN input,
each of the four amplifiers can also be used fully independently.
To this end, you may also use the AUX IN inputs in conjunction
with the BALANCE controls. When the BALANCE control is turned
to the left (“AUX” position), the MAIN signal is faded out, and the
AUX IN signals are fed into their respective amplifiers. Using
individual amplifiers separately lets you provide individual mixes
to up to four musicians.
Fig. 4.1: XLR connector
Fig. 3.2: Monitor live application
3.3 Using the DIRECT IN connector
The DIRECT IN connector (HA4700) is located on the left side of
the front section. For example, you can use this connector to provide
musicians with the signal of a DAT recorder or CD player. The
HA8000 has a separate DIRECT IN connector for each amplifier
(located on the rear). In the case of the HA8000, allocating a signal
to this connector mutes the MAIN IN signal. The input level must
be externally set in this case. This way, you can use each amplifier
section for a separate headphone signal.
Fig. 4.2: 1/4" TS connector
3.4 Mono mode
Stereo signals can often have an irritating effect in certain
monitoring applications, especially when performing live. These
negative effects are particularly apparent when both channels
show great channel separation, i.e. a different information content
coupled with varying volume levels. The ST./2-CH. switch
(HA8000: the MONO switch) allows coupling the left and the right
channels into a single mono signal, withouth needing a
“Y”-adapter or a special cable.
3.5 MUTE function (HA4700 only)
When the ST./2-CH. switch is depressed, the unit is running mono.
By depressing either one of the MUTE switches, the respective input’s
signal (i.e. either the left or the right input) is muted, while the signal
not being muted can be heard on BOTH (left and right) headphone
outputs. This allows you to feed two different program sources yet
be able to listen to only one of them on a per-need basis.
