Controls and Functions (150.4D)
Turn On Mode:
Signal: Senses audio signal on the speaker
level inputs (>800mVp) and on the line lev-
el inputs (>45mVp) to turn on the amplifier.
There will be a short delay in turn-off to
accommodate silence between tracks.
Offset: Senses the 6V BTL reference when
the speaker level inputs are connected to
the outputs of a BTL amplifier or head unit.
Rem: Senses the remote turn on output of
the head unit or to the car's ACC circuit.
Crossover Channels 1 and 2 (3 and 4)
Filter Type:
HP: Only the low frequencies below the
High Pass filter frequency selection will be
removed from the signal.
BP: Low frequencies below the High
Pass filter frequency selection and high
frequencies above the Low Pass filter
frequency selection will be removed from
the signal.
None: No high pass or low pass filter will be
applied. All frequencies will pass.
Low Pass Control Group:
50Hz-500Hz: Adjusts the low pass filter fre-
quency to any frequency between 50Hz
and 500Hz. High frequencies above this
selection will be removed.
X1-X10: When this switch is set to X1, the
:
filter frequency range is 50Hz-500Hz. When
this switch is set to X10, the filter frequency
range is set to 500Hz-5000Hz
High Pass Control Group
20Hz-400Hz: Adjusts the high pass filter fre-
quency to any frequency between 20Hz
and 400Hz. Low frequencies below this
selection will be removed.
X1-X10: When this switch is set to X1, the
filter frequency range is 20Hz-400Hz. When
this switch is set to X10, the filter frequency
range is 200Hz-4000Hz.
Input Config:
3Ch: Input 1 sends signal to output chan-
nels 1, 3 and 4. Input 2 sends signal to
output 2, 3 and 4. Inputs 3 and 4 are not
used. Outputs 3 and 4 will output the sum
of inputs 1 and 2 (1+2). Use when output
channels 3 and 4 will be bridged to drive a
subwoofer with two input connections.
2Ch: Input 1 sends signal to outputs 1 and
3. Input 2 sends signal to outputs 2 and 4.
Inputs 3 and 4 are not used.
4Ch: Each input sends signal to its corre-
sponding ouput (1-1, 2-2, 3-3, and 4-4).
Level:
Adjusts the voltage sensitivity (level) of
each pair of inputs. For line level input sen-
sitivity, Min is 10Vp and Max is 500mVp.
DO NOT APPLY MORE THAN 30Vp TO THE
SPEAKER LEVEL INPUT CONNECTIONS OR
THE UNIT WILL BE DAMAGED!
Power: This LED will light green to indicate
that the unit is on.
Protect: This LED will light red to indicate
a fault and the amplifier will produce no
sound. Faults include: power supply input
voltage is too high or too low, output
connection is short, amplifier heat sink
temperature is too high.
Notes about crossover settings: When
using any pair of amplifier channels in
BP (bandpass) mode, the HP (high pass)
frequency control MUST be set to a LOWER
frequency than the LP (low pass) frequen-
cy control. For example, if channels 3 and
4 will drive midrange speakers only, the LP
frequency control might be set to 3500Hz
and the HP frequency control might be
set to 100Hz. The signal sent to the speaker
will be frequencies BETWEEN 100Hz and
3000Hz. If there is no ouput from a pair of
channels, check these settings carefully.
