Owner's Manual 3

Part No. SW0724 Rev. B 02.2010

Loosely based on a dream sequence in which the technical writer is given keys to a

sports car of his choice, unlimited gas, and closed roads. The dream suddenly ends and

reality kicks in. A mixer manual to write, a mixer manual to write!

Set the levels

It’s not even necessary to hear what you’re doing to

set optimal levels. But if you’d like to: Plug headphones

into the phones output jack, then turn up the phones

knob just a little.

1. Turn on the mixer by pressing the top edge of

the power switch.

2. For one channel, press the solo switch in, and

the rude solo light will turn on.

3. Play something into that input at real-world

levels.

4. Adjust that channel's gain control until the

right main meter stays around the 0 dB LED

(marked "level set").

5. Disengage the channel's solo switch.

6. Repeat steps 2 to 5 for the remaining channels.

7. Turn up the channel level to the "U" mark.

8. Slowly turn up the main mix level until you

hear the signals in your speakers.

9. If needed, apply some channel EQ wisely.

10. Adjust the channel levels to get the best mix.

Keep the gain controls and levels fully down on

unused channels.

11. During the performance, if you notice a channel

OL LED turning on during peaks, carefully turn

down that channel's gain control until OL does

not turn on.

FireWire

• See page 42 for details of getting started with

FireWire.

• PC drivers are on the supplied CD-ROM. Mac

OS X contains built-in drivers, so no software

installation is required.

Other Notes

• When shutting down, turn off any power

ampliﬁ ers or powered speakers ﬁ rst. When

powering up, turn them on last. This will

reduce the chance of turn-on or turn-off

thumps.

• Always turn down the phones level when

making connections, pressing solo, or doing

anything that may cause loudness in the

headphones. This will help protect your

hearing.

• Always turn down the main mix level and

control room level when making connections to

the mixer. Better yet, turn off the power.

• Save the shipping box!

Quick Start

We realize that you must be really keen

to try out your new mixer. Please read the

safety instructions on page 2, then have

a look through some of the features and

details in this manual.

Setup

Use the mixer in a nice clean and dry environment,

free from dryer lint and dust bunnies.

Zero the controls

1. Fully turn down all the knobs to minimum,

except for the channel EQ and pan controls,

which should be centered.

2. Make sure all buttons are in the out position.

Connections

1. Make sure the AC power switch is off before

making any connections.

2. Push the linecord securely into the IEC

connector on the rear panel, and plug it into a

3-prong AC outlet. The mixer can accept

any

AC voltage ranging from 100 VAC to 240 VAC.

3. Plug a balanced microphone into one of the mic

XLR (3-pin) connectors. Or connect any

line-level signal (keyboard, or guitar preamp)

to a line input jack using a TS or a TRS 1/4"

plug.

4. If your microphone requires phantom power,

press in the 48V phantom power button.

5. You can connect a guitar directly to line inputs

1 or 2 without needing a DI box, if you ﬁ rst

engage the hi-z switch on these channels.

6. All 16 channels have insert jacks that can be

used to connect an external effects or dynamics

processor into the signal chain.

7. Connect the main outputs of the mixer (either

XLR or TRS 1/4") to the line level inputs of your

ampliﬁ er (with speakers already attached) or

to the line level inputs of powered speakers.
