Audio signal level converter with control
High-quality 2-channel converter that converts the speaker signal into an RCA line signal - input. 2x50W /output 2xRCA, smooth signal level adjustment. It allows you to connect an external amplifier to a radio player that does not have RCA (CINCH) outputs. It has a noise filter and separates the constant component (DC). It has a smooth adjustment of the output signal separately for each channel. REMOTE TURN ON/OFF output - a system for switching on and off an external power amplifier. Designed for radio players with a power of up to 2x50W. 2 RCA outputs (left and right channel)
Connection diagram:
- "L OUTPUT R" - RCA signal outputs for left (L) and right (R) channels connected to the RCA inputs of the amplifier
- "REMOTE" (power supply and Remote output for amplifier control)
(GROUND) - black wire - power supply mass (-12V) - connect to the power supply ground of the radio, amplifier or to the
vehicle body
(12V) - yellow cable - power supply (+12V) - connect, for example, to the power cord of a radio or amplifier
(REMOTE OUT) - blue cable - Remote output (+12V) for switching on/off the amplifier - connect to The Remote input
in the amplifier
- "INPUT" (signal inputs – speaker
white cable (L+) – connect to the speaker output from the radio
for the left channel with positive polarity (+)
black and white wire (L-) – connect to the speaker output from the radio for the left channel with negative polarity (-)
Ground – ground – connect to ground to minimize interference
gray cable (R+) – connect to the speaker output from the radio for the right channel with positive polarity (+)
gray-black cable (R-) – connect to the speaker output from the radio for the right channel with negative polarity (-)
Assembly:
Set the knobs of the potentiometers to min.
Connect the wires according to the wiring diagram
Turn on the radio by feeding the cables an external signal
Adjust the appropriate signal value with potentiometers
