1. Power Switch - This switch is used to control the units main power.

2. Channel 1 Gain Control - This rotary knob is used to control the output signal of channel one. Turning the knob in a clockwise direction will in

crease signal output.

3. Channel 1 Clip Indicator - This red LED will begin to ﬂash when channel one begins to overload (clip). At this point channel one will begin to distort. Under heavy clipping activity lower the channel one 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.

4. 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.

5. Function Indicators - This indicator details the operating mode of the ampliﬁer. This LED also functions as a power indicator.

6. Channel 2 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.

7. Channel 2 Clip Indicator - This red LED will begin to ﬂash when channel one begins to overload (clip). At this point channel one will begin to distort. Under heavy clipping activity lower the channel one 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.

8. Channel 2 Gain Control - This rotary knob is used to control the output signal of channel two. Turning the knob in a clockwise direction will increase signal output.
