The task of designing our new POWERPLAY PRO certainly meant  
a great deal of responsibility, which we assumed by focusing on  
you, the discerning user and musician. Meeting your expectations  
also meant a lot of work and night shifts. But it was fun, too.  
Developing a product usually brings a lot of people together, and  
what a great feeling it is when all who participated in such a project  
can be proud of what they’ve achieved.  
It is our philosophy to share our enjoyment with you, because  
you are the most important member of the BEHRINGER team.  
With your highly competent suggestions for new products you’ve  
made a significant contribution to shaping our company and  
making it successful. In return, we guarantee you uncompromising  
quality (manufactured under ISO9000 certified management  
system) as well as excellent technical and audio properties at an  
extremely reasonable price. All of this will enable you to give  
free rein to your creativity without being hampered by budget  
constraints.  
1. INTRODUCTION  
Congratulations! With the BEHRINGER POWERPLAY PRO,  
you have acquired a high-end headphone amplifier. Both  
POWERPLAY PRO units were developed with the most de-  
manding 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 appli-  
cations in studio environments.  
We are often asked how we manage to produce such high-  
quality devices at such unbelievably low prices. The answer is  
quite simple: it’s you, our customers! Many satisfied customers  
mean large sales volumes enabling us to get better purchasing  
terms for components, etc. Isn’t it only fair to pass this benefit on  
to you? Because we know that your success is our success too!  
Balanced inputs and outputs  
Both BEHRINGER POWERPLAY PROs feature electronically  
servo-balanced inputs and outputs. The servo function auto-  
matically 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).  
I would like to thank all of you who have made the  
POWERPLAY PRO possible. You have all made your own  
personal contributions, from the developers to the many other  
employees at this company, and to you, the BEHRINGER user.  
+
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  
reference.  
My friends, it’s been worth the effort!  
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  
damage.  
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.

POWERPLAY PRO-XL HA4700/PRO-8 HA8000  
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!  
Fig. 2.1: Input section  
+
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”.  
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  
of this model, the MAIN signal being fed in is automatically  
interrupted when the said input is in use.  
(see fig. 2.3). In the case  
+
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”.  
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.  
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.  
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.  
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  
needed for the registration is located at the top of the unit. Failure  
to register your product may void future warranty claims.  
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,  
additional information about power amps and effects processors  
is found there.  
ATTENTION!  
+
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.  
2. CONTROL ELEMENTS  
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.  
Fig. 2.2: Individual headphones amplifier sections  
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.  
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).

2. CONTROL ELEMENTS  
 
POWERPLAY PRO-XL HA4700/PRO-8 HA8000  
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  
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.  
instead of a ST./2-CH. switch  
.
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).  
Fig. 2.4: MAIN IN and MAIN OUT connectors  
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.  
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  
INPUT 1 and MAIN INPUT 2.  
2.2 Rear panel  
3. APPLICATION GUIDELINES  
Power is supplied via an IEC connector. The matching cable  
is provided with the unit.  
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 indi-  
vidual OUTPUT LEVEL controls are used for adjusting the desired  
channel volume only.  
FUSE COMPARTMENT / VOLTAGE SELECTION. Before  
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  
fuse.  
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.  
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.  
3. APPLICATION GUIDELINES  
5
 
POWERPLAY PRO-XL HA4700/PRO-8 HA8000  
This way, you can for example effortlessly record vocals and  
3.6 Connecting multiple headphones  
feed in an already existing playback using your POWERPLAY  
The HA4700 features three headphones connectors altogether,  
PRO-XL HA4700. The playback signal is fed through the MAIN IN  
while the HA8000 has two. You can connect multiple headphones  
inputs, and the preamplified vocal signal is fed into the AUX IN  
to an amp simultaneously, provided that the minimal output load  
connector. The respective BALANCE control should be set up in  
impedance of the amp does not fall below 8 Ohms. In the case of  
such a way that the singer gets a perfectly matched mix between  
the HA8000, the minimal output load impedance is 100 Ohms per  
the playback and the vocals, whereby the OUTPUT LEVEL control  
amp.  
regulates the overall volume.  
+
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 impe-  
dances does not cause deffective operation, you may experience  
a quality loss audible as lowered performance and distortion.  
4. AUDIO CONNECTIONS  
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.

Please assure that the unit is installed and operated  
only by people with an understanding of the unit’s  
functions. During and after the installation always make  
sure that those handling the unit are themselves  
properly grounded. Failure to do so may cause  
undesirable or faulty operation through electrostatic  
discharge.
