Connections - MC2 Audio T2000 Operating Instructions Manual

INSTALLATION: MECHANICAL
To ensure that this equipment performs to specification, it should be mounted in a suitable rack or enclosure as
described below. Like all high power amplifiers, it should be kept away from other equipment which is sensitive to
magnetic fields. Also, this amplifier may suffer a substantial reduction in performance if it is subjected to, or mounted
close to equipment which radiates high RF fields.
Warning: To prevent injury, this apparatus must be securely attached to the rack in accordance with the installation
instructions
When mounting the amplifier in a rack or enclosure, ensure that:-
1. The rear of the unit is adequately supported. The brackets which are supplied fit standard 19 inch (483mm) rack
mounting systems. THE FRONT PANEL IS NOT CAPABLE OF SUPPORTING THE UNIT ON ITS OWN.
2. THERE IS ADEQUATE VENTILATION. The cooling fans suck cool air in through the front and blow hot air
out at the rear of the unit through the ventilating grills. The front and rear of the amplifier should have free
exposure to the air (ie in a rack leave the front & rear doors off), with 2cm air gap at the sides. IF AIR IS NOT
ALLOWED TO ESCAPE FROM THE REAR, OVER-HEATING WILL OCCUR. Take care when mounting
other equipment in the same rack.
3. The rack unit has a separate earth connection (technical earth).

CONNECTIONS

INPUTS
The inputs are made via 3-pin XLR connectors, which are electronically balanced and should be connected via a high
grade twin core screened cable, as follows :-
The amplifier is designed to operate with fully balanced equipment and ground loops or loss of performance may be
experienced if connected to unbalanced sources. If it is unavoidable however, the following wiring should be used. The
cable should still be twin core plus screen.
PIN1 - Screen - connected to the chassis of the unbalanced equipment - or left disconnected at the unbalanced end.
PIN2 - Signal Hot
PIN3 - Signal Cold
NOTE: This amplifier is wired to the latest industry recommendations. PIN1 is connected directly to the
chassis/mains earth. If ground loops (mains hum) are encountered remove the screen connection
from the other end of the cable and leave it open circuit. If problems persist, consult your dealer/
supplier, DO NOT TAMPER WITH OR ALTER ANY GROUND (EARTH) CONNECTIONS
INSIDE THE AMPLIFIER.
For bridged operation input should be made to channel A only and the rear panel switch set for bridged mode.
PIN1 - Screen (see note)
PIN2 - Hot (signal +)
PIN3 - Cold (signal -)
