Phone Input Gain. This parameter adjusts the gain level of the Phone input.
Phone AGC. Enables or disables automatic gain control on the Phone.

The OUTPUT menu contains GAIN, NOM ACTIVE, and MUTE. As with the INPUT
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 dBu. Though the EF2241 allows for positive 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 EF2241, first check your
input gain to make sure you are getting a good level (around 0dB). Keep the output
gain at around 0 dBu. Then, for the best gain structure, use your amplifier to raise the
volume in your system.
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 1-4, A-D). The NOM attenuator will attenuate
the output signal by 10*log
10
(NOM) where NOM is the number 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 output.
Output Delay Enable. This allows you to enable delay to each of the outputs.
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.
Dynamics Processing. Enables or disables compression on Output T.
