6.Neutrick Connector Inputs a. Balanced XLR Inputs
These combined inputs are commonly used for both mobile and installation set ups. The XLR provide a good combination of ease of connection and resistance to corrosion. They are wired as per the following convention:
b. Balanced 1/4” Inputs
These types of jacks are featured on many audio products and are convenient if the amp is frequently connected and disconnected, such as for a mobile set up. The plugs used should be wired in the following way:
tip | ring | sleeve |
+ | - | gnd |
7. Balanced Barrier Strip Inputs
These connection points provide the best option for permanent or long term installation. Connections should be screwed down tightly to exclude oxygen, and care should be taken to avoid loose strands of wire that may cause short circuits.
+ - GND - +
8. Binding Post Outputs
BRIDGED MONO

These are suitable for banana plugs, spade lugs or bare wires. Spade lugs and bare wires should both be screwed down tightly to exclude oxygen, and care should be taken to avoid loose strands of wire that may cause short circuits.
9. Ground Lift Switch
This switch allows the circuit and chassis grounds to be separated in case of a ground conflict. In normal use the switch should be in the ‘ground on’ position. Lifting the ground (‘floating’ position) may resolve the ground conflict, but means that circuit grounding depends on other connected components. Deficiencies in the grounding of other components will affect the sound. A serious electric fault with the amplifier could damage other components in the system. For the best combination of safety and performance it is highly recommended to keep the switch in the ‘ground on’ position.
10. Stereo / Mono Bridge Switch
In stereo operation, each channel of the amplifier runs independently with its own signal and speaker(s). However, both channels can be configured to drive a single load with a single signal at twice the power.
To do this, follow these steps:
1 . switch the amp OFF
2.put one speaker of not less than 4 ohms impedance across the red (+) output terminals of the amplifier
