Two-Channel Amplifier Control Surface
The Amplifier Control Surface
This is the main user interface for the NE
two channel amplifier. Key features of this win
-
dow include:
1) Channel/Offset Link Group Faders - The
level control provides up to 40dB of analog input
attenuation. More than 40dB of cumulative at
-
tenuation causes the channel to mute. If a channel
has been assigned to an offset link group, a col-
ored triangular marker appears on the left side of
the fader graticule for secondary level control of
all channels in that group. The main level control
faders can not be linked to a group.
2) Mute button - This mutes the input
channel.
3) Polarity button - This inverts the phase
of the input channel.
4) Offset link group - Up to 16 groups
are available for the purpose of linking similar
function parameters across multiple channels. In
addition to the control surface secondary level
control (not the main fader), most DSP functions
have a link group check box in their work window
to assign a specific parameter to one of the 16 link
groups. Link groups can be renamed by clicking
on any group name and entering the new name
then pressing <enter> on the keyboard.
5) Attenuators - These two dials indicate the
physical position of hardware controls on either
the amp front panel or on a remote level control.
Note that these will display the current position of
attenuators even when disabled in software.
6) Total Attenuation - This indicates the total amount of attenuation being applied to the channel. This is the sum of the
following attenuators: main fader, offset link group attenuation, front panel and remote attenuators.
7) Meters - Input and Output meters display the real time activity per channel, in dB below rated output. Also, the ampli
-
fier’s operating temperature and output current are shown. Output current shows that the amplifier channel is actually delivering
output to a connected speaker load.
