Power supply Controls
Feature identification
The various switches, connectors, indicators and controls of the X-Series power supply are
called out and described below.
Front Panel
A) Power switch. Used to turn the unit ON and OFF, it also acts as the circuit breaker for the
supply. In the case of internal faults or overloads, the breaker will automatically switch to the
OFF position.
B) Exhaust Vents.There is an internal fan mounted on the rear of the unit.The fan brings cool air
in from the back and exhausts it through these front vents.To insure proper cooling,both these
vents and the rear fan should be kept clear of any obstructions.
C) DC Indicator LEDs.These four green LEDs show the status of the DC outputs of the supply.
When illuminated, they indicate that the associated DC voltage is OK.
Rear Panel
D) DC Output Connectors.These two parallel-wired connectors are used to connect the DC
output of the supply to the Console, either connector can be used.The spare connector is
used when a backup supply is also connected to the Console. For power supply to Console
connection, use the normal 25ft male-to-female cable.When attaching a spare supply, use the
4ft male-to-male DC-Link cable.
E) Ground Link.This terminal block makes both the Console Ground and PS Chassis Ground
available for connection.Normally a shorting-link is provided that ties the two grounds togeth-
er.The Console Gnd is the Audio Ground (0 volts) of the power supply, the Chassis Gnd is
the case of the PS chassis. Certain situations may arise where a hum-loop may occur due to
multiple ground paths being present in a system. Removing this shorting-link may solve a hum
problem by breaking one of those paths.NOTE:Removing this shorting-link does NOT lift the
PS chassis from the AC third-wire ground.The chassis is ALWAYS tied to the third-wire ground
of the AC inlet connector and is there for AC shock protection. If an internal fault occurs in
the power supply that puts dangerous voltage on the chassis, this third-wire connection is
there to shunt that potentially dangerous voltage to AC ground.That safety connection should
never be tampered with.
F) Cooling Fan / Filter. A quiet constant-speed fan draws cooling air in through the external fan-
filter and exhausts the heated air through the front panel vents.The filter should be cleaned
whenever dust buildup is observed.The snap-off cover can be removed to gain access to the
filter.The filter (foam) can be cleaned by rinsing with plain water or by vacuuming.
G) AC Inlet.This standard 15-amp IEC connector is used to bring the local AC mains voltage into
the power supply.The power supply is designed to work with any standard voltage used world-
wide; 100V to 240V 50/60 Hz.
