High Level Line Output Converter with autosense/bass remote
This converter is designed for use with head units in cars
without RCA low level output from the head unit. Most
modern car amplifiers are equipped with high level inputs
and these work OK with older factory radios but often will
not work with modern head units especially if they have
digital output chips.

This converer is designed to work with all head units
thanks to fully balanced 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. Perfect for adding subwoofer to a OEM
system with the EBC external remote.

Note: If using in 2 channel mode channels 1 + 2 must be
connected for the signal sensing circuit to function.
