Chapter 1: Introduction to the MC524
The MC524 Monitor Interface centralizes control room monitor and communication signals in one box and places them
under remote control by the system operator. The MC524 is a
digitally controlled analog signal router and level control device with a built in Talkback microphone circuit in a 2U rack
enclosure.
The MC524 receives the 22 monitor busses and two solo busses from the System 5 monitor matrix output and provides a
control room output to three speaker sets, four SLS/Cue monitor outputs as well as post preamp talk and listen mic outputs.
The SC253i Interface Pilot digitally controls the MC524 over a
15-pin control cable with a maximum length 100 m. The system operator can control all MC524 parameters from the System 5 control surface. There is only one MC524 in a System 5
configuration.
Applications
The MC524 allows the System 5 engineer to adjust all Control
Room communications (Level Control, Cut, Dim and speaker
selection) from the console Center Section. We recommend
installing the MC524 in the Control Room.
System Requirements and
Compatibility
Avid can only assure compatibility and provide support for
hardware and software it has tested and approved.
For complete system requirements and a list of qualified
computers, operating systems, hard drives, and third-party
devices, visit www.avid.com/compatibility.
Features
Mic Inputs
Mic level inputs are provided for four Listen and two Talk mics
on a 38-pin Elco connector. An analog gain stage provides
boost or attenuation for mic level signals. Talkback mic inputs
include phantom power and a compressor.
Line Inputs
There are 24 line level inputs for Control Room feeds, Monitor
A–D, and Solo. Line level inputs have attenuation only.
Line Outputs
Line outputs are on 90-pin Elco connectors for eight Monitor
A (up to 7.1 monitoring), two each for Monitor B–D, eight
Control Room Main (up to 7.1 monitoring), six Control Room
Alt 1 (up to 5.1 monitoring), two Control Room Alt 2, four Listen preamp, two Talk preamp out, and two Solo outputs.
All cabling is provided from the digital input to the final user
connections of the output patchbay. See the cabling diagrams
in Chapter 3, “Configuration and Connection.”

In 1 (38-pin Elco) Talkback, Listen Back and Mic inputs. This
connector receives four stereo listen channels and two stereo
talk mic inputs. All signals input at this port can be level
boosted or attenuated. In standard patch configuration, input
cable fans out to 12 XLR females.
In 2 (90-pin Elco) Control Room Busses, Monitor A, B, C, D,
and Solo busses inputs. This connector receives eight Monitor
A channels, and two each channels for Monitor B, C, D.
Signals input at this port can only be level attenuated. In
standard configuration these signals are fed from the AM713
converter.
Out 1 (90-pin Elco) Monitor A, B, C, D Speaker outputs. This
connector outputs eight Control Room channels, eight Monitor A channels, and two each channels for Monitor B, C, D,
and Solo. The output cable fans out to two 38-pin Elco connectors for the patchbay.
Out 2 (90-pin Elco) This connector outputs eight Control
Room Main channels, six Control Room Alt 1 channels, two
Control Room Alt 2 channels, four Listen pre, two talk pre and
two Solo channels. The output cable fans out to two 38-pin
Elco connectors for the patchbay.
Out 3 (DB-25 female) This connector outputs four Listen pre,
two Talkback pre, and two Solo channels, eight Monitor A
channels, and two channels each for Monitor B, C, D, and
Solo. The output cable fans out to eight male XLR connectors.
Control (DB-15) Input for digital control signal from Digital
Pilot. Signal format is Euphonix TCC bi-directional serial protocol. All patching, switching, and gain controls are communicated via this connection as well as MC524 IP address.
AC Line In (IEC) and Fuse Tray The power connector accepts
standard IEC power cords. 110, 220, or 240 VAC, 50/60 Hz can
be applied at this connector.

Chapter 3: Configuration and Connection 5
Phantom Power: 48V Jumper Settings
Phantom power is enabled by fitting the link to short pins 1 and 2. If not required (i.e., using a dynamic mic) then it should be
set to short pins 2 and 3. Pin 1 position can be ascertained by looking for the square pad on the solder side.
Pins set to phantom power
Note that the standard Talkback mic on the console (wired to T1) is a condenser type which requires phantom power.
The following table shows the mapping of the jumpers:

12) For products that are not rack-mountable: Use only with a cart, stand, tripod,
bracket, or table specified by the manufacturer, or sold with the equipment.
When a cart is used, use caution when moving the cart/equipment combination
to avoid injury from tip-over.
13) Unplug this equipment during lightning storms or when unused for long
periods of time.
14) Refer all servicing to qualified service personnel. Servicing is required when
the equipment has been damaged in any way, such as power-supply cord or plug
is damaged, liquid has been spilled or objects have fallen into the equipment,
the equipment has been exposed to rain or moisture, does not operate normally,
or has been dropped.
15) For products that are a Mains powered device:
The equipment shall not be exposed to dripping or splashing and no objects filled
with liquids (such as vases) shall be placed on the equipment.
Warning! To reduce the risk of fire or electric shock, do not expose this
equipment to rain or moisture.
16) For products containing a lithium battery:
CAUTION! Danger of explosion if battery is incorrectly replaced. Replace only
with the same or equivalent type.
17) For products with a power switch:
It should remain accessible after installation.
18) The equipment shall be used at a maximum ambient temperature of 40° C.
19) This unit is provided with a power supply cord set suitable for 120V AC input
only (for U.S.A.and Canada). For other than U.S.A. and Canada, a qualified
person must provide for use with this unit, an appropriate, approved power
supply cord set which is in compliance with the end use country requirements
and has a minimum cross-sectional area of 1.0mm2.
20) For units with more than one power cord:
CAUTION: This unit has more than one power supply cord. Disconnect two power
supply cords before servicing to avoid electrical shock.
ATTENTION: Cet appareil comporte plus d’un cordon d’alimentation. Afin de
prévenir les chocs électriques, débrancher les deux cordons d’alimentation
avant de faire le dépannage.
21) For products with an operator-accessible fuse:
CAUTION: For continued protection against risk of fire, replace only with same
type and rating of fuse.
ATTENTION: Pour ne pas compromettre la protection contre les risques
