REAR PANEL FEATURES

1. POWER IN – Use the included power adapter to connect the mixer to a power outlet.

While the power is switched off, plug the power supply into the mixer first, then plug the

power supply into a power outlet.

2. POWER SWITCH – Turns the mixer on and off. Turn on the mixer after all input

devices have been connected and before you turn on amplifiers. Turn off amplifiers

before you turn off the mixer.

3. VOLTAGE SELECTOR – This 2-position switch sets the input voltage for the speaker.

U.S. users should set this switch to "100-120V" whereas U.K. and most European

users will need to set this to "220-240V".

4. SPEAKER OUTPUTS – Use standard 1/4" or 4-way Speakon cables to connect these

outputs to a loudspeaker. Select the signal sent to these outputs with the POWER

AMP MODE SWITCH. The level of these outputs is controlled by the SPEAKER

OUTPUT VOLUME controls.

Note: To avoid damage to the built-in amplifier, please pay attention to speaker

impedance. Very low load impedances may damage the amplifier.

TOP PANEL FEATURES

Note: The channels have essentially the same controls with some minor variations between

Channels 1-16 and 17-20. The two different channel types are shown here.

1. PHANTOM POWER – Activates/deactivates phantom power. Set all faders to

minimum before activating phantom power

. When activated, phantom power

supplies +48V to the XLR mic inputs. Please note that most dynamic

microphones do not require phantom power, while most condenser microphones

do. Consult your microphone's documentation to find out whether it needs

phantom power.

2. PHANTOM POWER LED – Illuminates when the PHANTOM POWER switch is

on.

3. MIC INPUT – Connect a microphone to these inputs with an XLR cable.

4. LINE INPUT * – Connect line-level

devices to these inputs with 1/4"

cables.

5. INSERT – Use a standard 1/4" TRS

cable to connect an external

processor (such as a compressor,

limiter, external EQ unit, etc.) to this

jack. The signal will be taken after

the channel's gain control and

returned before the channel's EQ

controls.

6. GAIN – Adjusts the channel audio level (pre-fader and pre-EQ gain). Adjust this

so that the PEAK LED just barely lights up during the loudest parts of the song.

7. LOW CUT FILTER – When this button is depressed, that channel's audio will be

sent through a 75 Hz low-frequency filter with a slope of 18 dB per octave. This

is useful for reducing hum and other low-frequency noise when using

microphones.

* When using the line inputs 5/6, 7/8,

and AUX RETURNS:

• If you use only the left channel, the

channel is heard both in the left channel

and in the right and the balance will not

be adjustable.

• If you use only the right channel, the

signal will be heard only in the right

channel.
