Operating Manual - ne24.24M Matrix Processor

4. FRONT PANEL FEATURES

4.1 RS-232 Dataport

The ne24.24M has two RS-232 dataports wired in parallel, one on

the front panel and one on the back, for connecting to non-ethernet control

hardware. Protea NE Software does not work over RS-232.

4.2 Com LED

This green LED lights for a few seconds whenever there is com-

munication activity to the unit from a host PC. It is also used to respond

to an "identify device" command from NE software.

4.3 Preset Number

This displays the current preset number (1-31). The switch can be

disabled from software. To select a new preset, press and hold the switch

until the desired preset number is displayed. When the preset button is

released, the new preset is loaded. This display is also used to indicate

rmware revision during start-up, and status during factory reset.

4.4 Main Input Channel LEDs

The ne24.24M base unit has four xed input channels. Each input

channel’s two color Sig LED indicates input signal level of -20dB (green),

or +20dB clip (red) respectively. The Sig LEDs detect signal levels after

any gain adjustments are made within the ne24.24M preamp section. The

red input mute LED becomes lit when an input channel is muted through

software or remote control.

4.5 Main Output Channel LEDs

The four xed output channels on the ne24.24M have three color

LEDs to indicate signal, limiter threshold, and clip. The green signal LED

indicates -20dB output level. The amber limiter threshold LED depends on

settings established within Protea System Software, and, assuming the limiter

is active, indicates that sufcient signal level has been reached for the limiter to

begin the process of gain reduction. Clipping occurs at +20dB and is indicated

by a red LED. The red output mute LED becomes lit when an output channel

is muted through software or remote control.

4.6 Expansion Module LEDs

The ne24.24M is expandable by adding up to 16 additional inputs or outputs. Expansion modules of four inputs or

four outputs each can be eld installed by a qualied service technician. If an expansion card slot has been lled, its respective

amber LED (EXP 1, EXP 2, etc.) is automatically lit. The LED indicators on unused expansion slots do not light.
