Quick Start Guide 9
Line-level Sources and Guitars
Connect your line-level sources to the 1/4" TRS line
input connectors. Channels 1-4 have mono line inputs,
and channels 5-12 are stereo. Each line input can
accept TRS balanced or TS unbalanced sources.
Line-level sources include keyboards, drum machines,
electronic drum kits, CD players, iPod
®
docks, guitar
preamp outputs and so on.
If you have a mono source and the mono channels are
already in use, plug it into the left input (labeled left/
mono) of the stereo channels, and the signal will appear
equally on the left and right of the main mix.
If you have a stereo source and want to use channels
1 and 2 for example, plug the left side into channel 1,
and set the pan control fully-left. Plug the right side into
channel 2 and set the pan control fully-right.
LINE/HI-Z
Engage this switch if you want to connect guitars
directly to the 1/4" line inputs of channels 1 or 2.
For line-level sources, disengage this switch.
To connect guitars to other channels, you will need a
DI box, or they will not sound good, particularly the high
frequency response. This applies to most mixers and
channels in general, unless they have a hi-z switch.
LOW CUT
Channels 1-4 have a low-cut switch that cuts bass
frequencies below 75 Hz. The low cut switch affects the
line and mic inputs.
EQUALIZATION
Mono channels 1-4 have a 3-band EQ, with shelving-
low, peaking-mid, and shelving-high controls. The mid
frequency is adjustable from 100 Hz to 8 kHz.
Stereo channels 5-12 have a stereo 3-band EQ with
shelving-low, peaking-mid, and shelving-high.
These EQ options allow a lot of adjustment to your
line-level sources and guitars. Apply EQ wisely and
carefully, like makeup. (Too much and things can turn
ugly.)
TAPE IN and TAPE OUT
Use these RCA unbalanced stereo inputs to connect
the line-level outputs from sources such as tape decks,
CD/DVD players and iPod
®
docks. Engage the tape
switch to listen in your control room or phones. Engage
"assign to main mix" to add the sounds to the main mix.
For example, you can play intermission music, or listen
to rare reference material of your band getting it right.
The tape output is a copy of the main mix (post
fader), suitable for analog recording, sending to the
inputs of an external amplifi er, or sound card etc.
SETTING THE LINE INPUT GAIN
The gain controls allow you to set your input signals
to an optimum level: not so hot that the mixer is
overloaded, and not so low that the signal is lost in
noise. For a signal entering the TRS 1/4" line inputs,
the adjustment range is -20 dB to +40 dB for channels
1-4, and -20 dB to +20 dB for channels 5-12. Use the
following procedure for setting the gain just right:
1. Press the solo switch at the bottom of the
channel your source is connected to. The rude
solo light will fl ash to remind you that the
source playing in the control room,
headphones, and the right main meter is the
soloed channel.
2. Play your source at typical loudness levels.
3. Adjust the channel gain control until the right
main meter level is hovering around the 0 dB
mark (labeled "level set").
4. Now the gain is set correctly, disengage solo.
5. During a performance, if you notice that the
OL (overload) LED next to the channel fader
turns on, carefully decrease the gain until OL
no longer comes on.
