Power Supply / Outputs / other functions panel
HP 2 - HP 4
1_ + BATT (11÷15 VDC):
terminal block through the fuse holder supplied for the amplifier power
supply positive pole connection. The hole accepts cables up to 3 A.W.G. For the best current
transfer, we recommend the use of cables with as big a section as possible or, at least, with the
same section as the wire connected to the negative pole.
2_ GND:
terminal block for the amplifier power supply negative pole connection. Insert the battery
negative cable or a wire connected to the vehicle chassis here. The hole accepts cables up to
3 A.W.G. For the best current transfer, we recommend the use of cables with as big a section as
possible or, at least, with the same section as the wire connected to the positive pole;
3_ REM:
terminal for the Remote cable coming from the device which turns on the amplifier.
Voltage must be between 7 and 16,5 VDC.
4_ FUSE:
Fast access blade type fuse 40A (HP2 ) and 30A (HP 4) each one. They provide general
amplifier protection.
HP 2
5_ SPEAKER OUTPUT:
Amplifier speaker Right (R) and Left (Left) power terminals. The hole
accepts cable up to 10 A.W.G. When using HP 2 in mono mode the output is available at
terminals L+ and R-.
HP 4
6_ A CH SPEAKER OUTPUT:
A channels speaker Right (R) and Left (Left) power terminals. The
hole accepts cable up to 10 A.W.G. When using HP 4 A channels in mono mode the output is
available at terminals L+ and R- (A CH MONO).
7_ B CH SPEAKER OUTPUT:
B channels speaker Right (R) and Left (Left) power terminals. The
hole accepts cable up to 10 A.W.G. When using HP 4 B channels in mono mode the output is
available at terminals L+ and R- (B CH MONO).
Input Panel
HP 2
1_ PRE IN:
Preamplified inputs Right (R) and Left (L).Connect the outputs from the preamplified
section of the head unit or of an external electronic crossover.
When using HP 2 in mono mode use only Left input. When setting HP 2 in Lo-Pass 24dB mode you
can use either input or both as the amplifier performs the channels MIX to drive the amplifier in mono.
2_PRE OUT:
Preamplified outputs Right (R) and Left (L). The signal available on the output can be
filtered. It outputs the PRE IN input signals. If the amplifier is driven by a stereophonic signal, the
latter will be on these outputs.
3_ SPEAKER IN:
Amplified signals inputs Right (R) and Left (L).Connect the outputs from the head
unit amplified section. When using HP 2 in mono mode use only Left input. When setting HP 2 in
Lo-Pass 24dB mode you can use either input or both as the amplifier performs the channels MIX
to drive the amplifier in mono.
CAUTION:
Use SPEAKER IN input only with sources equipped with bridged output (BTL).
HP 4
1_A PRE IN:
A channels preamplified inputs Right (R) and Left (L).Connect the outputs from the
preamplified section of the head unit or of an external electronic crossover. When using HP 4 in
mono mode use only Left input.
2_B PRE IN:
B channels preamplified inputs Right (R) and Left (L).Connect the outputs from the
preamplified section of the head unit or of an external electronic crossover. When using HP 4 in
mono mode use only Left input. When setting HP 4 in Lo-Pass 12dB L/R MIX mode you can use
either input or both as the amplifier performs the channels MIX to drive the amplifier in mono.
3_PRE OUT:
Preamplified outputs Right (R) and Left (L). The signal available on the output can be
filtered. It outputs the A PRE IN input signals. If the amplifier is driven by a stereophonic signal,
the latter will be on these outputs.
4_A SPEAKER IN:
A channels amplified signals inputs Right (R) and Left (L).Connect the outputs
from the head unit amplified section. When using HP 4 in mono mode use only Left input.
5_B SPEAKER IN:
B channels amplified signals inputs Right (R) and Left (L).Connect the outputs
from the head unit amplified section. When using HP 4 in mono mode use only Left input. When
setting HP 4 in Lo-Pass 12dB L/R MIX mode you can use either input or both as the amplifier
performs the channels MIX to drive the amplifier in mono.
