(3) 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.

(4) 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.
(5) The BASS control (HA4700 only) attenuates or boosts the low frequency portions
of the signal (+/-12 dB).
(6) The TREBLE control (HA4700 only) attenuates or boosts the high frequency
portion of the signal (+/-12 dB).
(7) 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).
(8) The PHONES OUT connector is connected in parallel to the output connectors (18)
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.
(9) 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.
(10) The ST.12-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 (15)
(11) 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.
(12) Headphones volume of the individual amp sections is regulated using
the OUTPUT LEVEL control. Both the left and the right channel are
regulated simultaneously.
(13) 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.
(14) 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).
(15) 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.

(16) Power is supplied via an IEC connector. The matching cable is provided with
the unit.
(17) FUSE COMPARTMENT 1 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.
(18) 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.

(19) 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.
(20) 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.
