MAKE THE CONNECTIONS:

1.Make sure your amplifiers are turned off before making any connections.

2.Connect speakers to your amplifier’s outputs (unless, of course, you have powered speakers, such as the Mackie SRM 450 active monitors).

3.Plug all the sound system components into suitable AC outlets; properly grounded and capable of delivering adequate current. Use power strips to minimize ground loops.

4.Using TRS or XLR cables, make connec- tions from the mixer’s MAIN OUTS (12), (16) to your amplification system’s line inputs.

5.Make connections from your microphones and instruments to the mixer: Connect balanced microphones to the mono channel MIC (1) jacks. (For condenser microphones, engage the PHANTOM (19) switch.) Connect line-level instruments (synthesizers, guitar effects devices, direct boxes) to the mono or stereo channel LINE IN (2) (4) TRS jacks.

6.Follow the procedure shown on page 6 to zero the console. This will also MUTE (38) each channel.

7.Turn on all the AC power switches, includ- ing the mixer and all other equipment. Leave the amplifier’s power switch for last. This prevents power-up thumps which can damage speakers.

8.Turn up the MAIN MIX FADER (72) to the “U” label. You should hear nothing at this point.

SET THE LEVELS:

1.Choose one of the microphones or instru- ments you’ve connected. Make some noise. If it’s a microphone, speak at your normal singing volume. If it’s a synthesizer, play it at its normal output level.

2.While making noise, engage that channel’s SOLO (39) switch.

3.Turn up that channel’s TRIM (25) until the METERS (54) peak near the “0” label.

4.Disengage that channel’s MUTE (38).

5.Turn up the CHANNEL FADER (42) to the unity gain (“U” label). You should now be hearing your noise in the phones or control room (70).

6.If necessary, apply channel EQ (28-34) changes. Resultant level changes can be corrected by readjusting the TRIM (25).

7.Disengage that channel’s SOLO (39) switch.

8.Repeat steps 1 through 7 for the remaining active channels.

9.Stop making noise, start making music.

TWEAK THE MIX:

1.Engage MUTE (38) on all channels except your rhythm section (drums & bass).

2.Adjust the rhythm section’s channel PANs (37) and CHANNEL FADERs (42) to get a good balance of levels.

3.Un-mute the other active channels and adjust their pans and faders.

4.Tweak the fader, pan and EQ controls. Fine tune your mix. Walk the room to see how it sounds away from the mixer. Keep tweak- ing.

5.Consider applying the proper EQ adjust- ments by cutting certain frequencies, rather than boosting. Compensate for EQ cut by a slight boost in volume. For live sound applications, this technique allows for more gain before feedback, and gives improved system reliability.

KNOW THESE THINGS:

• Never listen to loud

music for prolonged

periods. See the safety

instructions on page 2.

• Never plug amplifier outputs into anything except speakers.

•Never use guitar cables to connect amplifi- ers to speakers.

•Before making connections to an amp or reconfiguring an amp’s routing, turn the amp’s power off, make the changes and then turn the power back on.

•When you shut down your equipment, turn off all the amplifiers first. When powering up, turn on the amplifiers last. This prevents power-up and power-down thumps which can damage speakers.

•Save the shipping box and packing mate- rial. You may need them someday.
