SYSTEM 10K Modular Amplifier Rack System

SYSTEM DESCRIPTION

The System 10K Modular Amplifier System is a flexible and efficient high
performance audio distribution system. The System 10K combines up to ten
amplifier modules with two (redundant) power supplies in a 5-1/4" high (3RU) by
19" wide Eurocard specification enclosure that is 14-1/2" deep. All modules plug
in from the front, are hot-swappable, are secured with captive hardware and
present an attractive and safe closed front panel. Aluminum extrusion
construction makes a strong and rugged enclosure and allows free convection for
vertical airflow. The basic frame provides power bussing for all positions.
Individual modules are supplied with mating connector assemblies which mount
on the rear of the card frame and plug into the power distribution bus. Connector
assemblies provide barrier block connections with fan-out strips for studio wiring.
Alternate insulation displacement, mass termination connector systems allow
simple push-on audio connections.

A wide variety of available interchangeable plug-in modules allow an optimum
system to be initially assembled at reasonable cost and expanded and upgraded
as future requirements necessitate. A partial listing of available SYS10K modules
follows. Consult factory for latest information.

DA100

A basic one-input, six-output Distribution Amplifier--A single power stage is split
into six active balanced outputs at +22dBm each. Split and bypassed build-out
resistors give protection against short circuits and RF. Balanced bridging input.
Single front-panel level control sets all outputs. Headphone monitor jack.

MDA100

Metered 1X6 Distribution Amplifier--Adds an LED Bargraph VU Meter to the
basic amplifier described above. Measures -21 to +6 VU with 0 VU adjustable for
outputs from 0 to +18dBm. Signal Alarm indicator and output warns of dead
channel.

CDA100

Compressing 1X6 Distribution Amplifier--Adds a Gated Compressor to the
MDA100. The compressor operates on inputs above -30dBm. Compression
Slope adjustable up to 20:1. Input level sensor gates compressor gain recovery

to prevent background noise build-up during program pauses. Meter is
switchable to Output or Gain Reduction levels. Switchable linear amplifier mode.

IDA100

Independent 1X6 Distribution Amplifier--Individual trimmers are provided for each
output along with a Master Level control. Headphone output plus six transformer
coupled (IDA100-1) or active balanced (IDAI00-2) outputs.

MIDA100

Metered Independent Output Distribution Amplifier--Six Transformer (-I) or Active
Balanced (-2) outputs with independent level trim controls. An LED Bargraph
meter is switchable to monitor all outputs and the input. Includes Master Level
Control and headphone output.

MIDA100-1RC

Remote-controllable Distribution Amplifier--Four transformer outputs, each with
an independent level trim control. Switchable Remote or Local DC-operated VCA
Master Level Control. An LED bargraph meter is switchable to monitor all four
outputs or the input signal. Includes Headphone output.

PS100

Power Module--A bi-polar unregulated 18 VDC supply drives the system power
buss through fused isolation diodes. Operates singly or as a redundant pair in the
right hand positions of each RM100 rack frame. Front panel LEDs indicate low
voltage on either buss or blown fuses. Power Failure Alarm relay contacts close
for any power loss and can activate an external alarm. Alarm outputs from both
PS100 positions are paralleled and brought to a barrier block (terminals 4 & 5)
mounted on the left-hand rear of the card cage. Dual power transformers in each
module run cooler and generate minimal hum field. DC lines are fully bypassed.
AC line filtering, non-concentric wound power transformers and varistor clippers
suppress power line transients and RF feed-through.
