XLR inputs connectors
These balanced XLR-3-31 type connectors are used to
connect input signals.
The pins are wired as shown below (IEC 60268).
* In bridged mode, only the first channel in the pair
is active; i.e., channel A of pair A/B. Make sure not
to input an audio signal to an inactive input termi-
nal.

Euroblock connectors
These balanced Euroblock connectors are used to con-
nect input signals.
3
HPF switches
These switches are used to turn on and off the HPF
(High Pass Filter) for each channel. When this is set to
20Hz or 55Hz, frequencies below the respective settings
are filtered using a 12 dB/octave high pass filter.
4
GAIN switch
This switch is used when changing the Gain of the A
and B channels simultaneously.
• +4dBu: The maximum output power can be
obtained when +4dBu is input.
• 26dB: Setting of 26dB
• 32dB: Setting of 32dB
5
MODE switch
• STEREO mode
In STEREO mode, channels A and B are completely
independent.
• PARALLEL mode
In PARALLEL mode, the channel A input signal is
sent both to the channel A power amp and the channel
B power amp. In this case, loads are automatically
connected between the A and B input terminals.
• BRIDGED mode
In BRIDGED mode, channels A and B operate simul-
taneously, functioning as a single mono amplifier.
