1:Power on-off switch - As you may have guessed, this is what you use to turn the MPL 1204 on and off. To avoid potential damage to your speakers, turn the MPL 1204 on before you turn on any connected power amps— and turn it off after the power amps are turned off.

2:Fuse - Contains a 1 amp, 250 volt fuse for 115 volt operation or a 0.5 amp, 250 volt fuse for 230 volt operation.

3:AC input - Connect the supplied standard 3-pin “IEC” plug here.

4:Mic inputs (1 - 12) - Use these electronically balanced XLR jacks to connect

microphones to the MPL 1204. These are intended to accept signal from low-level, low-impedance mics but can also be used for signal from other sources (such as direct injection boxes) if the channel’s Trim control (see #1 on page 4) is turned down. WARNING: Do not connect a channel’s microphone input if you already have something connected to its line input (see #5 below); all channels are designed to accept only one source or the other.

5:Line inputs (1 - 12) - Use these electronically balanced 1/4" jacks to connect

line-level sources such as synthesizers, drum machines, CD players, tape decks, or effects processors to any of the MPL 1204’s twelve channels. Use balanced three- conductor cabling and Tip/Ring/Sleeve (TRS) plugs wherever possible (unbalanced two-conductor plugs can also be inserted into these inputs, but you’ll get better signal quality and less outside noise and hum if you use balanced lines). The “Connecting the MPL 1204” section on page 11 in this manual provides more information on how best to use channel inputs. WARNING: Do not connect a channel’s line input if you already have something connected to its microphone input (see #4 above); all channels are designed to accept only one source or the other.

6:Channel Inserts (1 - 12) - Use these to insert an external effects processor (such as outboard equalizer, compressor/limiter or noise gate) into any of the MPL 1204’s channels in an “effects loop” configuration. These jacks accept 1/4" TRS plugs, with the ring carrying the send signal and the tip carrying the return signal. Normally, this will be connected to a Y-cord; see the “Connecting The MPL 1204” section on page 12 in this manual for more information and a wiring diagram.
