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.

INSTALLATION
MOUNTING

A fully loaded RM100 frame is heavy! To protect yourself and the equipment,
mount the empty RM100 enclosure securely before plugging in the power and
amplifier modules. The RM100 is designed for free vertical air convection
cooling. We recommend at least one rack unit (1-3/4 inches) spacing between
stacked units or forced air cooling of more densely stacked frames. If using
forced air, seal frames and joints between frames with duct tape and use blank
panels to seal any empty slots to avoid losing air pressure.

WIRING

The RM100 is supplied with mating connectors for the PS100 power supplies
mounted on the right side of the enclosure and with all power busing in place,
ready to plug on to the mating amplifier connector assemblies. Install amplifier
modules starting at the most left hand position (opposite from power supplies)
and stack side-by-side for optimum shielding of each module.

The connector assemblies supplied with each amplifier module mount on the rear
of the rack frame using supplied metric hardware: (4) M 2.5 x 6 mm screws.
System audio inputs and outputs connect to a 15-position barrier block using a
supplied mating fanning strip for easy pre-wiring. The 15-position fanning strip
may be cut into smaller sections if desired; e.g., inputs only, outputs only. The
fanning strip is Kulka P/N 649A15 and replacements are available from ATI
stock. Wire the audio inputs and outputs using the connector assembly markings
as a guide. NOTE: Barrier block screws are tightly machine inserted by the
manufacturer. Protect your knuckles by loosening them a few turns before
mounting them in a rack where they are hard to reach. Doing so will make it
much easier to install your pre-wired fanning strips at 3 AM. Fanning strips fit
onto barrier blocks from the left.

On special order, connector assemblies with .025 posts instead of the barrier
block are available. These posts mate with AMP MTA100 Series plug-on
connectors. The MTA connectors are solderless insulation displacement types.
Special tools for wire insertion into the MTA connectors include a simple and
inexpensive maintenance type tool, AMP 59803-1, and a precision ratchet type
self-indexing hand tool, AMP59801-1. Consult factory for more information.

The System 10K uses only three-wire grounded power plugs. The third wire
ground can cause a ground loop with your facility ground. If you are sure your
facility ground will provide adequate protection to personnel in case of an AC line
short to chassis, a 3-to-2 AC adaptor can be used to isolate the power line
ground. We recommend that the adaptor be removed and the power line ground
reconnected prior to any service work requiring removal of the facility ground
from the chassis.

To allow maximum flexibility in grounding in high RF environments, the circuit
grounds are isolated from case ground. An individual circuit ground is available
next to the HI input terminal of each module. These grounds are already
interconnected through the common DC power supplies. It is not recommended
that the individual circuit grounds be tied together since a ground loop would
result. A common DC ground is available on the ALARM terminal block pin 3.
This ground may be interconnected, tied to chassis or connected to a studio
ground system.

ALARMS

Alarm lines from the two power supplies are paralleled and brought to a barrier
block mounted on the left hand rear sidewall. The power alarm is connected to
pins 1 and 2. The power alarm outputs are reed relay contacts which close if
either or both DC output voltages drop below 11 volts due to excessive loading,
blown fuses or loss of AC power. The reed relay contacts should not be used to
switch high current lamp loads or AC line voltages. Several racks of distribution
amplifiers may be paralleled into a single alarm interface.

MODIFICATIONS
230 VAC OPERATION The PS100 Power Supply incorporates dual

transformer primaries that can be strapped for 115 or
230 VAC operations. To use on 230 VAC power,
remove jumpers J1 and J3 from the solder side of the
PSI00 PC Board and insert a jumper in the J2
position.

DUAL AC POWER Each PS100 of a redundant powered system may be

operated from a separately fused AC system for even
greater reliability. An additional AC line cord is
required and replaces the AC jumpers between the
power blocks of the two PS100 modules.
