Speaker-Level Inputs
The DQL-8 is designed to accept an amplified,
speaker-level signal from a factory source unit
or amplifier. You will want to refer to a factory
service manual or wiring-harness schematic to
determine which wires are the speaker wires for
your system. If you are unsure which wires are
the speaker wires, it is recommended you look
at the color of the speaker wire connected to the
speakers and follow them back to the factory
source or amplifier. Connect the speaker wires
to the Speaker-Level Inputs on your DQL-8. Make
sure to get your “pluses” and “minuses” connect-
ed properly.
Pre-Amp Outputs
Connect good quality RCA connectors from
these outputs to the inputs of your amplifiers.
While we won’t get into the discussion as to
whether plutonium cables sound better than
un-obtainium cables we will tell you that well-
constructed cables are less problematic in rugged
environments like your car system.
Summing The Outputs
The software in your DQL-8 allows you to
receive signals from the Main Inputs, along
with Channel 2, Channel 3, and/or Channel 4,
which can then be summed together internally.
The LED indicators on your DQL-8 will indicate
which channels are being summed. The shipped-
from-the-factory setting is in the “None” posi-
tion. See section on “Navigating the Menus”,
page 18, for more information.
When you have summed several channels
together, you will want to make sure the out-
put levels are providing a balanced frequency
response. A simple technique involves using a
pink noise CD and a real-time audio analyzer
(AudioControl happens to make a great one!)
1) Perform all of the steps necessary to install
your DQL-8.
2) Connect the Main Outputs from your
DQL-8 to the audio input on your real-time ana-
lyzer. Yes, your amplifiers will be disconnected
from the DQL-8 at this time.
3) Start playing pink noise on your CD player
and raise the volume level until signal is dis-
played on your real-time audio analyzer (RTA).
