1.Speaker Output Connections

Ensure that the speakers are connected observing correct polarity. 2 Ohm minimum speaker impedance for stereo operation

4 Ohm minimum speaker impedance for bridged operation

2.Fuses

Ensure fuses are replaced with the same type and rating.

3.Power

FUSION amplifiers should be connected directly to the 12V battery terminal with an inline fuse or circuit breaker as close to the battery as possible.

Ground

When grounding/earthing your amplifier ensure that the location is a good source of ground (preferably the floor pan). Make sure the metal is clean of paint etc, as a poor earth could damage your audio system.

Remote Turn On

This connection turns the amplifier ON and should be connected to the remote turn on lead from the Head Unit. If one is not available a switched 12V source must be used.

4.Output Connectors

Line level output for connection to an additional amplifier

5. Front Input Connectors

Choose the correct length RCA interconnects and run them to the RCA outputs of the source unit. Avoid running beside other looms and or power cable.

6.Front Input Level

This control is used to match the input level of the amplifier to the output level of your source unit

1.Turn the amplifier level to zero.

2.Turn the volume of the source unit to ¾ and the bass and treble to zero.

3.Adjust the level control until the desired maximum volume is achieved without distortion.

4.Failure to follow these steps may cause permanent damage to the audio system.

7.Frequency Control – Front X-Over

12dB/Octave crossover, variable from 32Hz to 320Hz. (For adjustment procedure see 16.)

8.Filter Selector – Front X-Over LPF – Select for subwoofer(s).

Flat – Select for full range speakers.

HPF – Select for mid/full range speakers when using a subwoofer in the system.

9.Bass Boost Control

Adjust the Bass Boost to the desired level.

10.Filter Selector – Rear X-Over LPF - Select for subwoofer(s).

Flat – Select for full range speakers.

HPF – Select for mid/full range speakers when using a subwoofer in the system.

11.Frequency Controller – Rear X-Over

12dB/Octave crossover, variable from 32Hz to 320Hz. For adjustment procedure see 16.

12.Rear Input Level

This control is used to match the input level of the amplifier to the output level of your head unit

1.Turn the amplifier level to zero.

2.Turn the volume of the head unit to ¾ and the bass and treble to zero.

3.Adjust the level control until the desired maximum volume is achieved without distortion.

4.Failure to follow these steps may cause permanent damage to the audio system.

13.Power ON LED

Amplifier is operational when illuminated.

14.Protection LED

When illuminated the amplifier is in protection mode due to any of the following fault conditions. Short Circuit, Thermal, Output Short, DC Offset.

15.Rear Input Connectors

Choose the correct length RCA interconnects and run them to the RCA outputs of the source unit. Avoid running beside other looms and or power cable.
