9.In STEREO and MONO, connect speaker cables to the SPEAKER OUTPUTS 
, either binding post or 1/4" TS:
• The binding posts are wired
red = positive (+) and black = negative
• The 1/4" TS connectors are wired
tip = positive (+) and sleeve = negative
10.In BRIDGE mode, using a single speaker:
•The speaker positive (+) connects to CH 1’s red binding post.
•The speaker negative
•Plug nothing into the black posts or the 1/4" speaker output jacks.
11.Plug the amp’s power cord into the IEC receptacle 
and the other end into a
12.Make sure the signal source feeding the M•800’s inputs is powered up and deliver- ing signals to the amp.
13.Turn the M•800’s POWER 
switch on and verify that the NORM 
Channel Status LED is on.
14.Slowly turn both GAIN
controls up: You should now hear the lovely music.
15.If the topmost LEDs (named OL, for OverLoad) are flashing, turn down either the GAIN controls on the amp or the source signal’s level controls (e.g., master faders). The point is: The OL LEDs should not light continuously in normal use.
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!)
Things to Remember:
• Never connect the
amplifier speaker outputs
into anything except
speakers (unless you have an outboard box specifi-
cally designed to handle
•Read and follow all the safety informa- tion shown on page 2 before using the amplifier.
•Turn the amplifier off before making any connections, reconfiguring cables or setting the rear panel switches.
•When you shut down your sound system, turn off the amplifiers first.
•When powering up your system, turn on the amplifiers last.
•Keep the load above 2 ohms for stereo and 4 ohms for bridge operation.
•Keep the LIMITER 
ON for most appliciations.
•Make sure the OL lights do not come on very often. Turn down the amplifier or mixer/preamp gain if they do. Failure to do this may lead to the amplifier over- heating, speaker distortion and damage.
•Save the shipping boxes! You may need them someday, and you probably don’t want to have to pay for them again.
