USB 3000
Class-D Power amplifier 3000 Watt
OPERATION
1. RCA Input Jacks
2. Input Level Control
3. Low Pass Frequency
4. Subsonic Filter
5. Bass Boost Control
6. Phase Control
7. Remote Control Jack
8. Master/Slave Switch
9. Slave Input Jack
CONTROL AND CROSSOVER
1. RCA Input Jacks- Low level-high impedance inputs.
Use high quality RCA cables designed for mobile applications.
2. Input Level Control- Adjust the input level for the marked channels.
Turn clockwise to increase the level, counterclockwise to decrease.
Amplifiers will run cooler and produce less system noise at lower level settings.
3. Low Pass Frequency- Adjust the crossover frequency by turning clockwise to set to a higher
frequency, counterclockwise to set to a lower frequency.
4. Subsonic Filter Frequency- Adjust the subsonic filter frequency by turning clockwise to set to a
higher frequency, counterclockwise to set to a lower frequency.
5. The Bass Boost control is used for a 0-12dB Gain at 45Hz for extra bass punch.
6. Phase Control- Adjust the relative phase of the output a range of 0 to - 1 80 degrees for solid bass
response and accurate imaging.
7. Remote Control Jack- For connecting the remote control module to the amplifier.
8. Master/Slave Switch- Select the remote level control or the on-board level control as the master control.
9. Slave Input Jack- Used to connect to another amplifier when bridging 2 amps together.
The Slave mode bypasses normal input jacks and controls.
