There is an optional Eclipse 37601 balanced line adapter and I do have a new one that I could sell with the deck. The 37601 takes the 16 volt balanced +/- double RCA pairs and converts them to 10 volt unbalanced single RCA pairs so you can plug in to any amp. This allows you to run a balanced signal on the long RCA runs to the back of the car. The 37601 is not needed to run the CD8053. For 8 volt output you can simply use the (+) RCA pairs from the head unit and leave the (-) pairs unused

37601 is available for an extra $75.00 shipped.





previously owned CD8053 for reference. Didn't want somebody to think the deck for sale had tape residue on the RCA's :p

Can the 37601 be used to convert unbalanced to balanced?
The 37601 was designed exclusively for use with the Eclipse CD8061, CD8062, and CD8053 8v/16v decks. It only has balanced inputs/unbalanced outputs. I suppose somebody smarter than me could reverse engineer it, but I don't know if it is possible.

The output pairs of the 8053 are inverted so one is positive phase and the other is negative (the output pairs are labeled + and -). A pair of RCA interconnects mates with the HU outputs and then connects to the 37601 which is located near the amps. The 37601 inverts one of the two paired inputs so that the two signals are now in phase and any noise in the signal is now inverted. When the two phased signals are added together, the amplitude of the original signal is doubled and the noise is canceled out.

This is the same technology used by Zapco with their Symbilink system and one or two others, like the Phoenix Gold TBA-1. Balanced signals are commonly used with microphones and high end audio electronics that use XLR connectors.
