RCA CONNECTION
Run RCA cables from your sound source to the
inputs of the amplifier. We suggest the use of high
quality shielded RCA patch cords to help to reduce
and eliminate unwanted electrical noise to your
system.
to avoid electrical noise from being injected in
to your sound systems be sure to run the RCA
cables on the opposite side of the vehicle that you
used to carry the power and ground leads of the
amplifier.
• RCA PReAMP oUtPUt. the preamp output is a full
range signal mixed from both input channels. Use
this signal to feed a secondary full range amplifier
in your system.
• 4-ChAnnel RCA InPUt (DAF 1004/1754). If your
head unit has only 1 pair of RCA outputs, you must
use a "Y" adaptor to split the signal to all four

SPEAKER CONNECTION
GENERAL WARNING
• DAF amplifier is extremely powerful and can
seriously damage any speakers which are not
specifically designed to handle such high power
inputs. thus, please ensure that your speaker
power ratings and impedance loading match the
amplifier.

input sensitivity from 200mv to 6v
(DAF 3001/5001/7001/12KW) or 300mv to 8v
(DAF 2502/4002/1004/1754).
to adjust the input sensitivity, turn the control
using a small flat head screwdriver fully counter
clock wise to the minimum position. Do not apply
any pressure while turning as this might break
the control unit. Adjust your radio volume level
(scheme #16)
to maximum volume. now turn the level control
(scheme #17)
on the amplifier clockwise towards the Maximum
marking until audible distortion occurs. When you
begin to hear any distortion in the sound, back
down one notch and your amp is set.
It is helpful to have a second person to help you
set the gain.
When setting up a multi-amp system, set each
amplifier's gain separately. Start off with the bass
amplifier, then adjust the highs amplifier's level
control to match.
once you are satisfied with the level control
settings, use any equalizer controls to adjust the
system tonal level for personal preference. Keep
in mind that after equalizing, you may have to go
back and reset the amplifiers level controls.
The level control of any car audio amplifier
should not be mistaken for a volume control. It
is a sophisticated device designed to match the
output level of your source unit to the input level
of the amplifier. Do not adjust the amplifier gain
to maximum unless your input level requires it.
If your unit has been professionally installed
please do not change the gain settings by the
installer, he is the professional!
Your system can also be extremely sensitive to
noise when the level is set to maximum and does
not match your input signal. the gain adjustments
need to be made only once when first setting up
the system.
