Initial start-up and functions
9 Remote Control
This input is used to connect an optionally available
remote control. The remote control allows you to
control the volume of the amplifier.
LPF
10
This control is used to fine tune the crossover fre-
quency of the lowpass filter from 15 Hz to 4,000 Hz.
Always use the respective Cutoff Frequency switch
first to adjust the filter (see page 21, item 22; Cutoff
Frequency switch).
HPF
11
This control is used to fine tune the crossover
frequency of the highpass filter from 15 Hz to
4,000 Hz.
Always use the respective Cutoff Frequency switch
first to adjust the filter (see page 21, item 22; Cutoff
Frequency switch).
Output Channel
12
Speaker outputs to connect loudspeakers. The
impedance per channel must not be lower than
1 Ohm.
Phase
13
This control is used to adjust the phase from 0° to
180°. This allows to match the phase of the sub-
woofer with the other speakers thus avoiding any
cancellations in the frequency response due to
phase shifts.
20
Bass Boost Frequency
14
This control is used to adjust the center frequency
of the Bass Boost from 40 Hz to 120 Hz. The adjust-
ed bass frequency can be enhanced from 0 to 9 dB
with control 15.
This is useful to emphasize or correct a determined
frequency of the subwoofer (kickbass).
Bass Boost Gain
15
This control is used to increase the adjusted Bass
Boost Frequency (see item 14) from 0 to 9 dB.
Level control
16
This control is used to adapt the input sensitivity to
the output voltage of the connected signal source.
This is not a volume control, it´s only for adjusting
the amplifier gain. The control range is 0.5 - 8 Volts.
The setting of the control also affects the digital
signal input of the optionally available HDM 1 mod-
ule if the SPDIF Direct In switch is not set to "On"
position.
