Muting for any of the first three inputs can be disabled. The muting circuit of input 1 can be disabled by moving the

jumper labelled JP1 (located on the front mixer PCB behind input 1 and 2's level controls). Simply move the jumper

towards the back of the chassis to disable muting from input 1.

To disable muting from input 2, simply move jumper JP2 towards the back of the chassis.

To disable muting from input 3, simply move jumper JP3 towards the back of the chassis.

Another feature of the muting circuit of the ACM120XL is the ability to have inputs 1 and 2 on the same priority level.

This is handy for situations where phone paging and microphone paging (for example) are of equal importance. In this

mode, both inputs can be used at the same time and both will mute all remaining channels. This feature is also handy for

emergency systems where signal from a pre-recorded message could be mixed with a live microphone. To set inputs 1

and 2 to the same priority level, move jumper JP4 towards the front of the chassis and remove and discard jumper J6.

Please note that both jumpers (J4 moved and J6 removed) need to be adjusted for this feature to work.
