A150.4D
High Fidelity Class-D Amplifier
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 amplier.
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 amplier 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 lter frequency selection will be
removed from the signal.
BP: Low frequencies below the High
Pass lter frequency selection and high
frequencies above the Low Pass lter
frequency selection will be removed from
the signal.
None: No high pass or low pass lter will be
applied. All frequencies will pass.
Low Pass Control Group:
50Hz-500Hz: Adjusts the low pass lter 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
lter frequency range is 50Hz-500Hz. When
this switch is set to X10, the lter frequency
range is set to 500Hz-5000Hz
High Pass Control Group
20Hz-400Hz: Adjusts the high pass lter 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
lter frequency range is 20Hz-400Hz. When
this switch is set to X10, the lter frequency
range is 200Hz-4000Hz.
Input Cong:
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 amplier will produce no
sound. Faults include: power supply input
voltage is too high or too low, output
connection is short, amplier heat sink
temperature is too high.
Notes about crossover settings: When
using any pair of amplier 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.
Controls and Functions (A600.1D):
The Turn-On Mode and Level control
for the A600.1D operate exactly like the
controls on the A150.4D. The Power and
Protect LED functions are also the same
as the 150.4D. Because the A600.1D is a
single channel amplier designed to drive
low frequency speakers or subwoofers, the
crossover controls are somewhat different
and are explained below.
High Pass 5Hz-40Hz: Adjusts the high pass
lter frequency to any frequency between
5Hz and 40Hz. Low frequencies below this
selection will be removed. For subwoofers
in vented boxes, set this control about a
half an octave below the frequency at
which the enclosure is tuned to prevent
too much excursion from damaging the
speaker. This is also useful for innite bafe
subwoofers. If your system doesn’t require
a high pass lter for the subwoofer, set this
control to its minimum setting (5Hz).
Low Pass 50Hz-500Hz: Adjusts the low pass
lter frequency to any frequency between
50Hz and 500Hz. High frequencies above
this selection will be removed.
Phase 0°-180°: Adjusts the phase of the
output at the crossover frequency be-
tween 0 degrees and 180 degrees. Use
this control to match the phase of the
subwoofer with that of the front speakers
to help blend the sound of the subwoofer
into the sound of the front speakers.
45Hz 0dB-15dB: Adjusts the amount of
45Hz in the output between 0dB and
15dB. Adjust this as you wish but be careful
because too much bass boost can cause
distortion at high output when the am-
plier runs out of available power at high
volume. Each 3dB of boost requires double
the power of the unboosted frequencies.
3dB requires twice the power. 6dB requires
four times the power. 9dB requires eight
times the power. 12dB requires sixteen
times the power and 15dB requires 32
times the power sent to the unboosted
frequencies.
Remote Level Control (optional): This
control, if installed, allows the level of the
output of this amplier to be controlled
from the front of the car. The RLC will vary
the output level of the amplier between
off (fully counter-clockwise) and the level
control setting selected with the level con-
trol on the amplier (above).
Using These Ampliers With a DSP: When
using these ampliers with a DSP, you
can (and should) defeat the A150.4D’s
on-board crossovers by selecting “None”
with the Filter Type switch if the lter will be
implemented in the DSP. When using the
A600.1D with a DSP, adjust the Low Pass
lter to its highest frequency (500Hz) and
the High Pass lter to its lowest frequency
(5Hz) if you will implement the high pass
lter in the DSP. You can also use the high
pass lter in the amplier to protect your
subwoofer from over excursion if your DSP
doesn’t include a high pass lter for the
subwoofer.
When Driving Tweeters Separately in an
Active System: Set the high pass lter
frequency about an octave above the
tweeter’s free air resonance (Fs). An oc-
tave is a doubling or halving of frequency.
So, if your tweeter’s Fs is 1.5kHz, set the
crossover at 3kHz.
Use a protection device to save your
tweeters in case of a mishap. A capacitor
and a resistor work well. Choose the value
of the capacitor to provide a -3dB point
about an octave below your crossover.
The values below are suitable for all Au-
diofrog tweeters.
