•The 1/4" TRS inputs are wired tip = hot (+), ring = cold
8.In MONO and BRIDGE modes, connect an input cable to CHANNEL 1’s INPUT only, and nothing into CHANNEL 2’s INPUT. (You could plug into CHANNEL 2’s input, it just won’t do anything.)
9.In STEREO and MONO modes, connect speaker cables to the SPEAKER OUTPUTS 
, either binding post or 1/4" TS for the M•1200, or binding post or Speakon® for the M•1400:
•The binding post connectors are wired red = hot (+) and black = cold
•The 1/4" TS connectors are wired
tip = hot (+) and sleeve = cold (–).
10.In BRIDGE mode, connect the binding post cable like this: the hot (+) side goes in the
CHANNEL 1 SPEAKER OUTPUTS 
red post and the cold
11.Connect the other ends of the speaker cables to your loudspeakers.
12.Plug the amp’s power cord 
into a
13.Make sure your signal source (the cables feeding the M•1200/M•1400’s inputs) is powered up and delivering signal to the amp.
14.Turn the M•1200/M•1400’s POWER 
switch on and verify that the signal present (SIG) LEDs are blinking.
15.Slowly turn both GAIN 
controls up: You should hear the music and see the SIG 
and meter 
LEDs flashing. If the topmost LEDs (named OL, for OverLoad) are flashing, turn down either the GAIN controls on the amp or the source signal’s output level controls (i.e., master faders). The point is: The OL LEDs should never light up.
16.For quieter listening, it is preferable to adjust the amp’s GAIN 
controls rather than the source signal’s output level (unless you have the source’s control all the way up!).
17.Start dancing, but don’t let the ants out of your pants.
Things You Must Remember:
• Never plug amplifier outputs into anything except speakers (unless you have an outboard box specifically designed to handle
•Before making connections to an amp or reconfiguring an amp’s routing, turn the amp’s level (GAIN) controls down, turn the power off, make the changes, turn the power back on, and then turn the level controls back up.
•If you shut down your equipment, turn off the amplifiers first. When powering up, turn on the amplifiers last.
•Save the shipping boxes! You may need them someday, and you probably don’t want to have to pay for them again.
