5. Level
Adjusts the input signal (master volume) to the amplifier (i.e. over all loudness / volume). Make sure this is not turned up when powering On or when switching the input (Mic/DI – Line).
6. Audio Input (XLR or ½”)
Balanced (Left & Right) XLR and 1/4 inch TRS connectors accept signals from balanced or unbalanced line level or Mic level sources. Signal at In is buffered and routed to Thru.
7. Audio Thru (XLR or ½”)
This Thru signal bypasses the controls and is a buffered output of the In signal. Allows the signal at In to be routed to another

8. LED indicators
A. Power Indicator: Illuminates when the system is powered On, (it should remain lit).
B. Limit Indicator: Illuminates when the protection limiter is active, (this may blink occasionally but should not remain lit).
C. Protect Indicator: Illuminates when the amp has shut down to protect itself.
Tip If this occurs, check the all connections, fuses, and make sure you have proper amperage in the outlet. D. Signal Indicator: An audio signal is present at the input, (normally is lit or blinks).
9. MIC/DI or LINE Switch
This switch allows the input to accept either a line level or a Mic level signal. Mic/DI is for a microphone or instrument Direct Input (i.e. acoustic guitar outfitted with a pickup). Line is for a line level output from an audio source such as a mixing board or a keyboard.
Warning When adjusting the Mic/DI switch please power Off the unit first or turn the gain all the way down. Adjusting the switch to the wrong setting while the input gain is up can result in very high SPL levels, which can damage hearing!
10. NO SUB or SUB Switch
Select the No Sub position when a dedicated subwoofer is not being used. This position provides more bass for full range use.
Use the Sub position when a dedicated subwoofer is used. This position reduces some low frequency information that may interfere with your subwoofer frequencies creating a “muddier” or
Tip For the best results, experiment with the Sub switch. In the Sub position, it removes bass frequencies below 100 Hz and allows the
11. OFF or CONTOUR Switch
The Contour switch provides a boost at high frequency & a slight boost to the low end (when the Sub/No Sub switch is in the No Sub position). When engaged, the switch can be used in quiet environments where lows and highs may need a slight boost; or in situations where high frequencies need to carry over longer distances. For best results, please experiment with the Contour switch.
