In addition, there are four global mixer groups (A-D). They support first-mic priority,
maximum number of mics, etc., and work across all linked PSR1212s. Unlike the
audio buses, they contain only mic status and gate parameters. All gated mics are
default routed to the A mixer and to the O bus for routing.
Global Mixer Group
s A-D These mix-minus buses are defined as microphone mixing
buses which support first-mic priority, maximum number of mics, etc. and work
across all linked PSR1212s. Unlike the audio buses, they contain only mic status and
gate parameters. All mics are assigned to the A mixer group by default.
P
A Adapt Buses E1-E4 Allows an input from a PSR1212 to reference an output on
another linked PSR1212. See PA Adaptive Mode on page 41 for more information.
Network Requirements
The Expansion Bus (RS-485 LAN) lets you connect up to eight PSR1212s. The
maximum distance between interconnected Gentner units is 80 feet (24 meters).
Gentner recommends that category five twisted-pair (10BaseT LAN) cable be used.
Equipment Placement
The PSR1212 is designed to mount in a 19" (48.26cm) equipment rack. Do not block
the ventilation holes. With a desktop kit, it can be adapted for tabletop use.
Environmental Requirements
The PSR1212 can be safely operated in a room with varying temperatures between
32° F (0° C) and 110° F (43° C).
Installation
Follow the step-by-step instructions on the following pages to install your PSR1212(s).
A complete PSR1212 installation example is shown below.
