Use this parameter to select mic or line level on Inputs 1-8.
Mute.
This selects which input channel (1-8, A-D) or the W, X, Y, or Z input
is muted. The default is not muted.

Use this parameter to turn phantom power On or Off
for inputs 1-8.

menus, this is done on a per channel basis.
Output Gain.
Choose the gain applied to each output signal using this
parameter. The default setting is 0 dB. Though the EF2280 allows for pos-
itive output gain, you should always try to adjust input gains to a good level
so that the output gain is 0 dB. If you find that you need a positive output
gain from the EF2280, first check your input gain to make sure you are get-
ting a good level (around 0dB). Keep the output gain at around 0 dB. Then,
for the best gain structure, use your amplifier to raise the volume in your sys-
tem.
Mute Output.
Use this to mute or unmute each Output.
NOM Active.
This allows you to select whether the NOM attenuator is
active for a particular output channel (Outputs 1-8, A-D). The NOM attenuator
will attenuate the output signal by 10*log
of open microphones in that particular output channel. NOM is calculated
based on the number of open microphones for each signal that is in the out-
put.
Output Delay Enable.

Output Delay.
Sets the amount of delay on the output. The default value
is 0 ms. The range is 0 to 340.0 ms in 0.1 ms increments.
