Mackie M1400/M1400i Owner's Manual - Page 5

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 posts, 1/4" jacks, or Speakon®, depending on your model: • The binding post connectors are wired red = hot (+) and black = cold (-). • The 1/4" jacks are wired tip = hot (+) and ring = cold (-). • The Speakon connectors are wired pin 1+ = hot (+) and pin 1- = 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 CHANNEL 2's red post. Plug nothing into the black posts, Speakon jacks (on the M•1400), or the 1/4" TS jacks (on the M•1400i). 11. Connect the other ends of the speaker cables to your loudspeakers. 12. Plug the amp's power cord into an outlet properly configured with the correct voltage for your amplifier, and capable of delivering enough current to reach full power. 13. Make sure your signal source (feeding the M•1400/M•1400i's inputs) is powered up and delivering signal to the amp. 14. Turn the M•1400/M•1400i'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: • Read and follow the safety instructions on page 2, and the hearing protection details on page 3, before using the amplifier. • 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.
