1. IN/OUT (RCA) Jack
For strapping two of the same model
X-Treme
D Class amps together. Connect the input of the
MASTER to a suitable source via a shielded RCA interconnect cable and connect the MASTER
OUTPUT RCA jack to the corresponding RCA jack on the SLAVE amplifier. Then select the
MASTER/SLAVE switch properly.
2. MASTER/SLAVE Switch
Two like amplifiers can be connected together and bridged into a single 2-ohm (min) load. The level
and frequency controls on the SLAVE amp will be disabled. Only the amplifier you select as the
MASTER will control these functions.
3. PHASE Control
This variable control can be used to correct any “phase” or “time delay” effect in the system by
bringing the low frequency from the rear of the vehicle to the front.
4. GAIN Control
This control is used to match the input sensitivity of the amplifier to the particular source unit that
you are using.
5. BASS EQ Control
This equalization circuit is used to enhance the low frequency response of the vehicle’s interior.
With up to 18dB of boost centered at 45 Hz, the BASS EQ can be adjusted to meet your own
personal taste.
6. BASS REMOTE Jack
This is the connector port for the Remote Bass Control. When using this control set the BASS EQ
control (#5) to the maximum 18 dB position. Now the amplifiers low frequency equalization circuit
can be adjusted from the driver’s seat.
7. LPF (Low Pass Filter) Control
This control is continuously adjustable from 50 Hz through 400 Hz at 24 dB per octave.
8. SUB SONIC Control
This filter allows high pass of frequency and is adjustable from 20 Hz through 50 Hz to provide an
extra level of speaker protection.
9. POWER Indicator
The clear L.E.D. lights BLUE when the power is on.
10. PROTECTION Indicator
This RED L.E.D. turns on when the built-in protection circuitry is activated. This indicates a problem
with the system in relation to the amplifier.
11. LINE IN (RCA) Jacks
These RCA style input jacks are for use with source units that have RCA line level outputs. A
