JBL continually strives to improve its products. New materials, production methods and design refinements are introduced into existing models without notice as a routine expression of our design philosophy. For this reason, Power Series Multichannel Automotive Amplifiers may differ in some respects from their published specifications and descriptions, but will always equal or exceed the original specifications unless otherwise stated.

Multichannel Automotive Amplifier

Test Conditions and Notes

All tests to be done, unless otherwise specified, from 10Hz to 50KHz at 14.4V DC into 4 ohm loads and adjust the units gain so that with a .775 volt input signal the unit is at Its maximum rated output. All measurements will be done using an Audio precision system one and the supply voltage.

An A+ line voltage of 14.4V DC shall be applied to the unit under test for all measurements unless otherwise specified. The voltage applied to the unit shall be measured at the power connection on the Amplifier.

Signal Source Unless otherwise specified, all tests shall be conducted with the Audio Signal Generator output configured to be balanced, less than or equal to 50 ohm source impedance, and floating. The signal source "GND" shall be connected to the Amplifier PWR GND at the Amplifier.

Output Load Unless otherwise specified, all tests shall be conducted with 4 ohm resistive loads having less than 10% reactive components at any frequency below 75KHz. Each resistor shall have a value that remains within 1% while dissipating the rated output of the unit under test.

Power Indicator Green LED steadily illuminates for normal operation. Illuminates up Red LED blinks when protection circuitry is engaged, and during power up.

Controls and Connections

1. It allows left and right input channels to be connected to the amplifier using RCA plugs.

2. Speaker Output Connector - Connect speaker wiring to these connectors. See wiring instruc tions on page 4 for more information.

3. Fuse - Two 20 Amp ATC type Fuses.

4. Power Connection for 12V+, GND and REM connections for power wires. See wiring instruc tions on page 4 for more information.

5. Input-Level Control - Adjusts input sensitivity for pre-amp level and speaker level inputs.

6. Frequency adjustment-When the LPF/FLAT/HPH switch is either in the LPF or HPF position,this sdjusts where the frequency response of the amplifer rolls off on the upper or lower end of the range,depending on switch position.

7. When this switch is in the FLAT position the amplifier operates at full range grequencies. When in the LPF position, the Bass frequencies;when the switch is in the HPF position,the amplifier operates in the Upper frequencies.

8. It allows left and right input channels such as higf level speaker output signals to connected to the amplifier

Mounting the Amplifier

The JBL Power Series amplifiers can be mounted in virtually any location inside the vehicle. However, make sure to keep the amplifier away from heater vents or ducts.

1. At the chosen site, use the amplifier as a mounting template and mark the locations of the four mounting holes.

2. Drill a small pilot hole at each marked location.

3. Mount the amplifier and securely tighten the mounting screws.
