Functions And Operations:
1. Power, Ground, & Remote Disconnect:
12V constant power, ground, and factory
source unit remote turn-on (if available) connections to the appropriate terminal of the
supplied disconnect plug.
2. Remote Control Module Connection:
Connect one end of the supplied Remote Control
Module Cable to this port. The other end should connect to the Remote Control Module.
3. Delayed Remote Turn-On:
Connect a lead to the remote turn-on terminals of the other
components in the audio system. This remote turn-on has a built-in delay to eliminate
unwanted pops.
4. Radio Ground:
Connecting a wire from this terminal to the Radio's ground wire will eliminate
ground loops and eliminate or greatly reduce this type of induced noise.
5. Front High Level Input:
Connect the front left and front right factory source unit speaker
level outputs to the High Level Front Input terminals. (consult the vehicle manufacturer for
the correct factory source unit wire configuration)
6. Rear High Level Input:
Connect the rear left and rear right source unit speaker level outputs
to the High Level Rear Input terminals. (consult the vehicle manufacturer for the correct
factory source unit wire configuration)
7. High Level Subwoofer Input:
Connect the subwoofer source unit speaker level outputs to
the High Level Subwoofer Input terminals. If the factory stereo system does not have a
subwoofer and subwoofer control within the source unit, set the Subwoofer Source Selector
to 4 Ch. Mix, eliminating the need for a High Level Subwoofer Input connection. See #11
Subwoofer Source Selector below for further information.
8. Signal Sense Indicator:
The Current Sense Indicator will illuminate if the processor has
been activated by receiving power from the remote input, or sensing audio signal to the
high-level inputs. Signal sensing eliminates the need to connect remote turn-on power. A
built-in delay prevents the processor from turning off between song tracks. The processor
remains active approximately 1 minute after audio signal is lost.
9. Clipping Indicator:
The Clipping Indicator will illuminate if the Low Level Output signal
is clipped regardless of voltage. A clipped signal is noticeable to a trained ear in the form
of distortion, which can and will cause damage to all speakers.
10. Power Indicator:
The Power Indicator will illuminate when and while the unit is receiving
power.
11. Subwoofer Source Selector
Set the Subwoofer Source Selector to High Level Sub In if
the factory source unit has speaker level outputs and source unit control for a factory
subwoofer. Connect the factory source unit subwoofer speaker level outputs to the High
Level Subwoofer Input terminals. If the source unit does not have subwoofer control or
dedicated subwoofer high level output wires, then set the Subwoofer Source Selector to
4 Ch. Mix. The processor will now use the signal from the Front & Rear High Level
Inputs as the subwoofer signal.
12. Front Channel Input Sensitivity:
Set the Front Channel Input Sensitivity to closely match
the factory source units maximum front channel output voltage. The minimum setting is 4V,
the maximum is 30V. You can use the clipping indicator to help properly set this control. If
the clipping indicator lights up frequently, then turn the control down a bit until the clipping
indicator remains off.
13. Rear Channel Input Sensitivity:
Set the Rear Channel Input Sensitivity to closely match
the factory source units maximum front channel output voltage. The minimum setting is 4V,
the maximum is 30V. You can use the clipping indicator to help properly set this control. If
the clipping indicator lights up frequently, then turn the control down a bit until the clipping
indicator remains off.
14. Subwoofer Channel Input Sensitivity:
Set the Subwoofer Channel Input Sensitivity to
closely match the factory source units maximum front channel output voltage. The minimum
setting is 4V, the maximum is 30V. You can use the clipping indicator to help properly set
this control. If the clipping indicator lights up frequently, then turn the control down a bit
until the clipping indicator remains off.
15. Subsonic Filter Control:
Set the Subsonic Filter Control to the desired subsonic filter
frequency. The minimum frequency is 15Hz, the maximum is 50Hz, Generally, subsonic
filters are set between 20-30Hz to avoid harmful low frequencies that will damage sub-
woofers. The power wasted on subsonic frequencies will now be useful in the audible
sub bass region.
16. Bass Boost Level Control:
This control allows you to set the amount of boost desired.
Be careful not to overdrive the subwoofer and pay attention to the clipping indicator.
17. Boost Q Level:
will increase or decrease the bandwidth of frequencies boosted above
and below the selected Bass Boost Frequency. The minimum setting of Narrow will
boost only a small range of frequencies above and below the Bass Boost Frequency,
while the maximum setting of Wide will boost the largest range of frequencies above
and below the Bass Boost Frequency.
18. Bass Boost Frequency Control:
The Bass Boost Frequency Control will select the
desired frequency to be boosted. The minimum frequency is 30Hz and the maximum
is 80Hz.
19. Low-Level Front, Rear & Subwoofer Outputs:
RCA connections for Low-Level Front,
Rear, & Subwoofer Output signal. Use RCA cables to connect the RCA outputs to the
low-level inputs of the corresponding amplifier(s) if the source unit is equipped with RCA
outputs.
