Speaker connections to RM20

speakers, coaxial
or component,
connected to left
& right channel.
One 4 ohm
subwoofer
connected in
bridge mode
to the outer
connections of
the speaker
terminal.

NOTE!
Minimum amplifier load in stereo is 2 ohm, lower
impedances may damage the amplifier.
NOTE!
Minimum amplifier load in bridge mode is 4 ohm.
This connection gives a 2 ohm load with a 4 ohm
subwoofer (the load is halved when connected in
bridge mode).
The low pass filter is
mostly used for
subwoofers. It will allow
low frequencies only and
blocks higher frequencies.
A typical setting is 50 –
70 Hz.
The
Subsonic filter
blocks
the very deepest
frequencies from reaching
the subwoofers. It can be
set from 15 to 150 Hz and
can be switched on / off.
A typical setting for
subwoofer use is 25-30
Hz
The high pass filter can also be used to block
very
low frequencies from reaching the speakers. It is
mostly used at say 60 Hz to protect small speakers
( like 6 inch and smaller ) from deep bass.

BASS EQ
0 +6
dB
BASS EQ
is used to increase the bass
volume at a low frequency.You can
select the amplification between 0 dB (
no amplification ) and +6 dB ( full
amplification ) at
80 Hz center frequency.
This function is used to compensate for
the bass function on your front system
and adjust for your own taste of bass.
Set level control at 0 dB if you want it to
be inoperative.
