Issue 1
Introduction
General
The rack has 9 balanced audio Monitor inputs from the digital engine
intended to be used for up to 8.1 monitoring.
There is a single balanced audio Calibrate input which can replace the 9
input signals for speaker output level setting.
There are 3 balanced audio inputs for Dialogue; each channel of which
mixes into the monitor channels on left, right and centre respectively.
There are 9 balanced audio inputs for Effects; each channel of which
mixes into the corresponding monitor channel.
The three paths - Monitor, Dialogue and Effects - can be independently
controlled for level. The controlling software will create an aggregate level
control value for each path depending on control room level, dim level
settings and speaker selection.
Each of the 9 balanced sums of Monitor, Dialogue and Effects can then be
switched onto any of three 9 wide output paths nominally titled Large
Speakers, Small 1 Speakers and Small 2 Speakers.
The left and right channels can also be selected to a pair of Mini Left and
Right outputs. A function called LSRSFlip mutes L and R and replaces
them with LS and RS for surround monitoring in the front speakers.
There are a pair of Return Talkback inputs with automatic volume controls
which can be selected onto both Small Speaker outputs or onto the Mini
Speaker outputs.
The rack has the capability of being level controlled by voltages to allow a
very basic compatibility with earlier Remote Level Control Units or by
Tranlink.
RS 485 and RS 232 input control will become available at a later date.
All the Inputs and Outputs are available on varicon connectors.
Throughout this document, the abbreviation MonFac is used.

Mechanical
The unit is a 4U 19inch rack .
The front panel has a profiled silver brushed finish with a standard AMSNeve logo.
There are two mains switches on the front panel giving indication of power
supply operation and enabling either or both supplies to be switched off.
The rear of the unit has two IEC power connectors; one for each of the
two power supplies.
There

are 4 x 56 pin Varelco connectors containing
9 Monitor inputs
1 Calibrate input
9 Effects inputs
3 Dialogue inputs
2 RTB (return talkback) microphone inputs
9 Large speaker outputs
9 Small 1 speaker outputs
9 Small 2 speaker outputs
2 Mini speaker outputs
There is a 9 pin D-type control connector compatible with the existing DFC
analogue rack (see Control below).
There is also a 25 pin D-type with the DFC control signals plus others
called the Extended control connector (see below).
There are RJ 45 Tranlink In and Out connectors and 9 pin D-type RS232
and RS485 connectors for processor control.
Control
The rack can be controlled one of four ways:
• Via hardwired voltage and logic lines referred to as DFC 9PIN MODE
and EXPANDED 25PIN MODE.
• Via ‘transputer’ link.
• Via RS232
• Via RS485
RS 232 & RS 485 will be implemented at a later date.
Switches on the MonFac rack processor board will select which system the
board should use.
AC Power
The rack is powered via two IEC mains connectors and two independent
power supplies to give full redundancy.
If a power button on the front of the unit fails to light when switched On,
check the relevant supply inside the unit.
Please contact AMS Neve for replacement power supplies.
The AC current required by each supply is approximately 120mA at
240volts.
Input voltage: 90-132/180-264 V AC – autoranging
Input frequency: 47-63 Hz

Hardwired Voltage and Logic Lines
The current DFC has a voltage control line and several logic control lines
for its audio output box.
The MonFac rack implements those lines on a 9 way connector and then
duplicates those and adds more controls on a 25 way Tranlink connector.
