VCA’s (Voltage Controlled Amplifiers) & ELECTRICAL PIN-OUTS

Used in Professional Audio for some years, but totally new to the car audio world, is a remote control gain devices called a “VCA”. This is a small integrated circuit that can control the feed- through gain of a circuit from a remote location. It operates uch like an external “hand” that controls the signal flow through a circuit, much like a simple water flow valve.

Many people want to have a remote control for a high power amplifier in order to control the loudness of a subwoofer amplifier independently of the radio. Remote mounting of an input gain control would be a major problem with most car audio amplifiers because of the likely noise intrusion into the signal path.

With a VCA circuit on the input of an amplifier, the gain can be controlled remotely but is done with moderate level DC voltages (O-1 5 volts) that are insensitive to noise (noise is an AC voltage). Using the optional Blaupunkt remote control (RM-1) you simply plug the remote into the amp to control the overall gain. For people wanting to interface with highly custom installations, you can use an RJ-11 telephone jack and variable resistor to achieve similar results using the circuit below, This is & recommended for very experienced Blaupunkt installation centers for it may void the warranty of the amplifier otherwise.
