ADVANCED OPERATION • PRESET CONFIGURATION PANE

Preset Configuration Pane

The Preset Configuration pane, to the left of the Preset matrix (see graphic on page 56), allows

preset programming of the DB25 Control/Status Ports A and B on the rear of the PSR1212 unit, as

well as provides options for running and saving presets.

Preset Selection

Beginning at the top of the window, the Preset Selection menu allows you to select which preset

you wish to make changes to.

Preset Description

Use the Preset Description window for entering information about the preset.

Preset Mask Control/Status Port B Configuration

The Preset Mask allows you to enable each Command/Status Port B pin with either an active high

(H), active low (L), or off (left blank) status.

A typical application using the Preset Mask is a group of conference rooms with removable

partitions between them. For the first partition, an automatic switch would be connected between

Pin 1 and the partition (or, a manual switch would be connected to Pin 1 and be located on the

wall near the partition). You would configure the Preset Mask Pin 1 setting to H (high) for when

the partition is closed, and L (low) for when the partition is opened. This would trigger different

presets based on the room-combining needs of each situation. See the description of Preset

Mask Control in the Application Example on page 73 for more information.

The Change Preset Label button opens the

Change Preset Labels window, where you can

name or rename each preset. Click Close to

save changes and return to the Preset

Configuration pane.

window. This window displays three parameters

for each of four internal and four global gating

groups. The three parameters are Max # of

Mics, First Mic Priority, and Last Mic Mode.

Gating Controls Window

the Gating Controls window does not feature Use in Preset

boxes, and all items are immediately selectable.
