Installation and Startup Guide

Rio Rancho, NM

Rear Panel

Power Inlet

The switching power supply will operate with line volt-

ages between 100 and 240 VAC. The inlet socket is a

standard 3-pin C14 type that accepts any cordset with a

C13 connector.

Cooling Fan

The microprocessor monitors the internal temperature

of the processor and controls the variable speed fan as

needed. Operating temperature is very well regulated.

RS-232 and Ethernet Ports

Each host assembly provides RS-232 and Ethernet

ports for communication with the microprocessor. The

ports can be utilized simultaneously for monitoring,

setup and control.

ASPEN Ports

This gigabit bus transports audio and data from one

board to the next through CAT-6 cabling and RJ-45 con-

nectors. Processors are normally installed with the Mas-

ter unit on top and Slave units below it. The cabling is

then connected from the uppermost jack on one board

to the lowermost jack on the unit just above it. See page

9 for more information.

Balanced Mic/Line Inputs

Every mic/line input is a balanced, differential type with

adjustable gain from -10 to +60 dB. Connectors are a

standard 5-pin Phoenix depluggable type with adjacent

channels sharing a common ground.

Balanced Outputs

All outputs are a balanced, differential type. Channels 1

through 8 on each board are nominal line level outputs

with gain adjustment from -60 to +20 dB. Channels 9

through 12 on each board are also line level outputs

with switchable attenuation of -20 and -40 dBu nominal

levels (mic level), with gain adjustment from OFF to +20

dB.

Programmable Input and Output Ports

Programmable inputs and outputs used to control

levels, settings, indicate the current state of a program-

mable input and control a variety of other parameters.

ASPEN Bus Data/Audio Ports

These RJ-45 jacks carry the audio signals and con-

trol data between each system board as well as units

stacked together.

Remote Control

These RJ-45 jacks provide interfaces for RCWTH4

remote control units. Each jack is assignable to CODEC

1 or 2, or to the telephone line.

Conferencing Inputs and Outputs (Codecs)

Analog audio input and output connectors for the Codec

ports.

Telephone Set/Line

RJ11 jacks for connecting a standard telephone line

and a single-line telephone set.

Power Amp Outputs

The ampliﬁer is designed to run continuously (idle or

with a load) without heat buildup, making it ideal for

permanent installations where prolonged operation is

required.
