34. Headphones Level Control and Output Jack

 

The level control regulates the output of the headphone amplifier. The headphone output jack is located on the front of the mixer beside the Phantom Power switch. The head- phone program originates from the main L/R buss unless a solo is active in which case it originates from the Solo bus.

35. Amplifier AMP A, B, C and D Inputs

Each Amplifier Input uses a switching jack that cuts off internal signals routed to the power amp when a jack is Inserted.

The Amplifier Inputs have a few possible uses. For example, they enable you to access, and isolate the main power built-in amps so that they may be used in conjunction with an electronic crossover (used to bi-amp subwoofers and full-range speakers.) In this case you would patch as follows,

i.PowerMAX L/Mono Line Level Output to the crossover’s input (if it is a stereo cross- over, pick one channel and use its input).

ii.From the crossover’s low frequency, or subwoofer output to the PowerMAX Amp A

Input.

iii.From the crossover’s high frequency output to Amp B Input.

iv.Now, connect the subwoofers to the Amp A Speaker output/s and the full-range cabi- nets to the Amp B Speaker output/s.

Two 8 ohm full-range speakers, and two 8 ohm subwoofers can be powered this way. Actually, if you have a 3-way crossover or processor and only need one monitor power amp, you can tri-amp by using Amp A for subs, Amp B for woofers and Amp D for horns and/or tweeters.

Alternately, the Amplifier Inputs can be used to slave one or more of the power amps

–perhaps if the mixer is connected to a rack of amps and now the built-in amps are free to be used for other things. In another case, you might be using the PowerMAX L&R Line Level Outputs, also Mon 1 and 2, patched into four of another mixer’s input channels. Now you may want to amplify the full mix coming out of that other board including whatever it’s doing (possibly you’re jamming with another group and you need extra channels). You would simply patch its main and monitor outputs into the appropriate Amplifier Inputs and now the two mixers are linked and the PowerMAX amps are ready to power up main and monitor speakers.

36. Amplifier Full Power LEDs

approaching the point where the mixer will begin to clip.
