GX-3000 FRONT PANEL

1. Racking Mounting Ears - 

Two front panel mounting holes are provided 

on each mounting ear.

2. UNiKA Logo and Model No - 

GX series have 1 type of 2U model 

GX-3000 and 3 types of 3U models GX-4000 / GX-5000 / GX-7000.

3. Channel 1 Signal Indicators - 

These green and yellow LEDs will glow 

according to the average signal output.

4. Channel 1 Clip Indicator - 

This red LED will begin to flash when the 

channel begins to overload (clip), at this point the channel will begin to 
distort. Under heavy clipping activity lower the channel's gain control to 
reduce the risk of damage to your speakers and amplifier. This LED may 
glow when the unit has been turned off, this is normal.

5. Channel 1 Protect Indicator - 

The red Protect LED will begin to glow 

when the channel goes into protect mode. When the channel goes into 
protect mode all output for that channel will turn off. This is to protect 
any speakers connected to the channel.

6. Channel 1 Limiter Switch - 

This is used to activate the channel's built 

in limiter. The limiter reduces the average input level when the signal 
begins to distort, this process is designed to reduce distortion and 
protect the speakers. See limiter at page 15. 

7. Function Indicators - 

These indicators detail the operating mode of the 

amplifier. These LEDs will also function as a power indicator.

8. Channel 2 Limiter Switch - 

This is used to activate the channel's built 

in limiter. The limiter reduces the average input level when the signal 
begins to distort, this process is designed to reduce distortion and 
protect the speakers. See limiter at page 15.
