5 Signal Delay Mode - This allows the user to put the DQDX into Set-Up
mode and adjust the signal delay settings using the dash control. See page 9 for
details on setting this up.
6 Ground - Connect to a good, veried chassis ground (the battery is the best
possible location.) Since factory ground wires typically have multiple devices
connected to them and could cause ‘Noise’ in the audio system, we would rec-
ommend to NOT use factory ground wires or locations.
7 +12V Power - Connect to a good source of 12-Volt power. Be sure to use
a fused connection that does not exceed 2 Amp. Doing so may damage your
DQDX.
8 Remote In - This is the ‘on’ and ‘off’ selector for your DQDX. Connect this
wire directly to your source unit 12Volt trigger wire. If your source unit is not
equipped with a 12 Volt trigger wire then nd a reliable source in the vehicle that
comes on when the key is in the ‘On’ position and turns off when the key is in
the ‘Off’ position.
9 Remote Out - Connect the 12 Volt turn on lead for your aftermarket ampli-
ers directly to this connection and not to any other. This is critical to eliminate
any ‘clicks’ or ‘pops’ during power up and power down cycles.
0 Maximized Indicators - These brightly colored LED’s indicate when the
signal level coming into and going out of your new DQDX is just below clip-
ping. When properly level matched with your source unit these LED’s should
just barely ‘icker’ occasionally when your system is playing at its maximum
volume level. Please refer to the section on Level Matching, page 13 for a more
detailed step by step process (trust us…. This one is important!)
Power - If you have connected all of your power wires correctly, this light
should be bright red when your system is on and ready to go!
Remote Level Control (ACR-3 Included) - In the Set-Up mode, this con-
trol is used for setting up the signal delays. In Normal mode, it will give the user
Subwoofer level control. Additionally, if you press and hold the remote down
for 4 seconds, the outputs of the DQDX will turn from music to Pink Noise.
This will assist in the proper setting of the EQ and Delay. When the DQDX is in
Normal mode, pressing the remote momentarily will defeat all processing on the
DQDX (Equalizer and Signal Delay). This is very helpful during set-up to make
sure the changes you make to the EQ and Delay made the difference you were
looking for.
Pre-Amp Outputs - These RCA plugs should be connected directly to your
amplier inputs. Do not connect any speakers directly to your DQDX and de-
nitely do not connect to any home appliances like your coffee maker or toaster!
Parallel Outputs - The DQDX is equipped with a unique circuit that al-
lows for the Front input signal to feed the Subwoofer outputs. See page 12.
