DLS Svenska AB A1 - Manual (Page 6)

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:

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.
