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.
