Low dist 3V output noise rejection HLC problem solver, loading resistors compatible with digital output chips, summing ch 3/4 for sub w optional EBC



This converter is designed for use with factory radios in cars without RCA low level output. HLC4.2 is designed to work with all head units thanks to fully balanced noise rejecting input circuits. The converter can be used for both 2 -and 4 -channel amplifiers and have up to 3v output to minimize noise in amp input section.

Number of channels: 4

Power supply: 12 V DC (min 10,8, max 15,6V)

Current draw, no signal: 4 mA

Current draw, operational: Typical 25 mA

Output voltage: 3 V RMS

Distortion: 0,002% THD @ 3V output, 10 kohm load

Clip point: 3,7 V RMS @ 14,4 V power supply

Output impedance: 200 ohms nominal

Input impedance: Ch. 1: 44 ohms, Ch. 2-4: 100 ohms, All channels are fully balanced

Sensing modes: DC level or Audio, both operate on Ch. 1 only.

Remote output: 12 Volts, max 100 ma max, protected against short term short circuit

Indicators: Green= Remote on, Blue = Audio sensing active

Reverse polarity protected.Summing output ch 3 + 4 for subwoofer amp when used with optional EBC
