106 MAESTRO — Installation and Service Manual
Section 3 — Hardware Installation
WARNING Some Maestro components use a manual switch to adjust the power
supply according to the local mains voltage level. Observe the following
steps carefully to avoid equipment damage and personal injury.
a. Check the 115/230 VAC selector switch on the rear of the GUI PC.
This switch can be changed using a small flat-blade screwdriver.
b. Check the wall-mount power supply provided with the touch
screen LCD for a voltage selector switch. If there is no switch, verify
that the supply’s auto-sensing is suitable for the local power mains.
c. Check any other PC provided with the system (such as a
configuration PC) for correct power switch settings.
• The Maestro/Concerto 8 RU frame, 4 RU frame, and hardware
control panel power supplies are auto-ranging from 100 to 240 V,
50/60 Hz.
Installing the Maestro Master Control Panel
Follow these steps to install the Maestro Master Control panel:
1. Mount the Maestro/Concerto frame in a rack or other suitable
enclosure that provides power and cooling facilities for the equipment.
The frame is designed to be mounted in a standard 19-inch (48 centime-
ters) wide equipment rack having a depth of 24 -30 inches (61- 76 centi-
meters). Rear support is recommended, especially in a remote
equipment truck or in other locations subject to vibration and stress.
Proper attention should also be given to ventilation and cooling of the
frame. See Air Intake/Exhaust Locations
on page 416 . The Maestro Pro-
cessor boards can be installed in any order in the 8 RU frame. For the 4
RU frame, the Maestro board must only be mounted in the bottom slot
(Slot 2).
The rear-panel battery is installed at the factory and does not require
activation by the end-user. (For more information about the rear-panel
battery, see Processor Backup Battery
on page 79 .)
2. Connect the required video and audio cables.
Please refer to the drawings starting with Figure 47 on page 112 for the
following discussion. If the system has an integrated Concerto router
(that is, has Concerto boards mounted in the Maestro/Concerto frame),

a. Inputs
The Maestro inputs must be provided by a GV-controlled matrix router.
During operation, the operator assigns a subset of the router’s inputs to
Maestro’s control surface. As the operator performs transitions
between these sources, Maestro sends switching commands to the
control system/router so that the next source is always available on the
