Directed Electronics HCCA-D1200 - Manual (Page 4)

PRACTICE SAFE SOUND™
Continuous exposure to sound pressure levels over 100dB may cause permanent hearing
loss. High power automotive sound systems can generate sound pressure levels in excess of
130dB. When playing your system at high levels, please use hearing protection and avoid
long term exposure.
RECORD YOUR SERIAL NUMBER AND DATE
To ensure your warranty (see back cover), please record the following information regard-

END PANEL LAYOUTS
1. RCA Input - accepts RCA input from a head unit, preamplifier, or equalizer.
2. RCA Line Output - provides easy connection to additional amplifiers.
3. Master/Slave Switch - controls whether the amplifier is a slave or master when
connected in combined amplifier configurations. (Refer to the Combined
Amplifiers section of this guide.)
4. Gain Control - continuous adjustment for full power output.
5. Infrasonic Switch - when On cuts off extremely low bass frequencies (below the
range of human hearing, that speakers cannot effectively reproduce). The high
pass filter is engaged when the infrasonic switch is On. This improves efficiency of
the amplifier’s power supply, improves sound reproductive performance, and
reduces chances of damaging the subwoofers.
6. High-Pass Frequency Control - adjusts the frequency of the high-pass crossover.
7. INTELLi Q Control - continuously adjusts the "Q" boost of the high-pass
crossover from 0 to 10dB of boost.
8. Low-Pass Frequency Control - adjusts the upper crossover frequency of the
amplifier.
9. Remote Bass Input - connects optional HP-RB1 remote bass control to control
the bass level from the driver’s seat.
