Line Outputs
This mixer features balanced line outputs for your sound reinforcement equipment.
There’s also an unbalanced, compressed RCA output for FM transmitters, recording devices,
etc. The balanced outputs can provide a level in excess of +20dBm. Following equipment
should be capable of a similar maximum level. When any equipment is driven beyond its
maximum level, it “clips”, flattening audio peaks – resulting in a characteristic distorted
sound. You get the least noise from your equipment (best
signal-to-noise ratio
) when
everything clips at the same level. Thus, it is best when following equipment can handle at
least +20dBm.
Check the specifications of following gear. If necessary, you can reduce the mixer’s
output by loading it with a resistor as shown below. Wire this resistor into the connector at
either end of the cable between the mixer’s balanced output and the balanced input of the
next device. The numbering at the amplifier input assumes the amp has a XLR input
connector. Follow the amplifier’s wiring instructions generally:
R value: Atten.:
600 ohm 6 dB
300 ohm 10 dB

Four
balanced outputs
are available:
•
MAIN – It provides the complete mixed and equalized output,
normally
connected to the system’s power amplifier for auditorium listening.
•
MUSIC
– A separate mix of only music (the two AUX inputs, plus any
reconfigured MIC inputs), without EQ.
•
VOICE
– A separate mix of only the remaining MIC inputs – including the
individual mic EQs but not the main voice equalizer.
•
MONITOR
–. Includes the two AUX channels, as well as any other
channels selected at USB setup (see page 28). The factory setting
excludes
MIC 3
and includes everything else.
The
Compressed RCA
output:
•
This output provides the MAIN program (the complete mixed and
equalized output). It features full-time dynamic limiting to optimize level
for recording devices, FM transmitters for hearing impaired, and similar
uses. We do not recommend driving your amplifier with this output. This
compression is separate and in addition to the selectable compression on
each microphone.
