FRONT PANEL

1.  Power Switch -

 This switch controls the units main power. 

 This is used 

to activate the channels built-in limiter. The limiter reduces the average 
output level when the signal begins to distort, this process is designed 
to reduce distortion and protect the speakers. See limiter page 13.

3. Channel 1 Clip Indicator -

 This red LED will begin to f lash when 

channel one begins to overload (clip). At this point channel one will be-
gin 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 pro-
tect any speakers connected to the channel.

5. Power Indicator - 

This blue LED will glow when main power is ap-

plied to the unit. This light may continue to glow brief y after main power 
has been turned off, this is normal.

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 pro-
tect any speakers connected to the channel.

7. Channel 2 Clip Indicator -

 This red LED will begin to f lash when 

channel two begins to overload (clip). At this point channel one will be-
gin 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 Limiter Switch (

) -

A-800 & A-1300 Only

 This is used 

to activate the channels built-in limiter. The limiter reduces the average 
output level when the signal begins to distort, this process is designed 
to reduce distortion and protect the speakers. See limiter page 13.

9.  Cooling Vents -

 These vents are used for proper cooling. Never 

block these vents and keep them clean at all times. 

10. 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 increase signal output.

11. Channel 1 Signal Indicators -

 These green and yellow LED’s will 

glow according to the average signal output.

12. Channel 2 Signal Indicators -

These green and yellow LED’s will 

glow according to the average signal output.

13. 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.
