RS2.1200
HP PASS
(HighPass)
Controls the frequency response
of
your speakers downwards. The Cut-off frequency is continously variable from 50Hz up to 400Hz.
LOW
PASS
(LowPass)
Controls the frequency response
of
your speakers upwards. The Cut-off frequency is continously variable from 50Hz up to
400Hz.
If the X-OVER - Switch is set on
LP
-position, so the HP PASS-controller is activated as Subsonic-Filter, who eliminates the lowest frequencies to
protect the speakers from damages.

Connections

INTERCONNECTION EXAMPLE 2-Channel Mode: 1x Stereo System (Front or rear)
RCA & Speaker wiring:
• Connect the RCA lineouts
of
the headunit with the RCA jacks LINE INPUT at the amplifier with appropriate high-value RCA cables.
• Connecl the front
or
rear speakers with the speaker outputs (LEFT -/+ and RIGHT -/+ SPEAKER ) by using appropriate wires.
• Ensure by any means, that the total impedance load
of
all speakers is not lower than 2 ohms. Too low impedance cause high temperature
and wil shut down the amplifier operation.
• Always ensure the correct polarity
of
the speakers. The interchange
of
plus and minus cause total loss
of
bass playback and could
damage the speakers.
Caution!
Do not
connect

• By using bigger speakers (more than 20cm) you can set the X-OVER switch to the FULL position (Full Range Signal).

FULL
• By using smaller speakers (8.7cm -16cm) you must set the X-OVER switch to the HPF Position (Highpass Mode) to avoid any damage
by lower frequencies on the speakers. The cut-off frequency is adjustable with the HIGH PASS controller and should be set between
40Hz to 500Hz,depending on the size
of
the speakers.
• The LOW PASS Controller is not

use
in
this interconnecting example.
LEVEL CONTROLLER
• Turn the LEVEL controller
of
the amplifier to the
6V
position.
• Turn the volume controller
of
the headunit to 80 - 90%
of
its full setting.
• Turn the LEVEL controller clockwise until you hear some distorlion.
• Then turn back the LEVEL controller slightly until you hear a cleaner sound.
BASS BOOST CONTROLLER
• The BASS BOOST controller must be turned to 0 dB position
in
this interconnecting example .
