• The 1/4" TRS inputs are wired
tip = hot (+), ring = cold (–) and
sleeve = shield (ground), and can accept
either balanced (TRS) or unbalanced (TS)
cables.
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 (–) side goes in
CHAN-
NEL 2’s red post. Plug nothing into the
black posts, 1/4" TS jacks, or Speakon jacks.
11. Connect the other ends of the speaker
cables to your loudspeakers.
12. Plug the amp’s power cord
into a
3-prong AC outlet capable of delivering at
least 15 amps.
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 speaker-level
signals).
•
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.
