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
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.
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
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.
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.

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.

Power is supplied via an IEC connector. The matching cable
is provided with the unit.
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.

headphone outputs
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.
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.
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
INPUT 1 and MAIN INPUT 2.
3. APPLICATION GUIDELINES

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.

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.
