Input Wiring

DLS A7 has a more sofisticated input configuration and can be connected in different ways which are described here. Inputs are low level from the RCA output of the car stereo head unit.

Low level input

Use a pair of shielded stereo audio cables with RCA type jack. Most trunk-mount amplifiers need a 20 feet RCA cable ( appr 5 – 6 meters). Most under the seat installations require 12 feet ( 2 – 3 meters) RCA cables. Avoid placing the RCA cable close to spea- ker cables, power cables and

remote control cable.

The amplifier has separate input sockets for front, rear and sub channel.

There are two switches located under the amplifier

bottom plate. With these switches you can choose different ways to connect the RCA input sockets internally. You can use either one, two or three separate RCA cables for the feed. Use any of the following:

1. One RCA cable feed to all amplifier inputs. If you want to use only one RCA cable to feed all inputs set the switches like in the example below:

A singhle RCA feeds all channels
