Please ensure that you read and follow the
IMPORTANT SAFETY INSTRUCTIONS at the front of this manual and the
SAFETY WARNINGS and INSTALLATION CONSIDERATIONS given below.
Safety Warning
To prevent shock or fire hazard, do not expose the unit to rain or moisture. To avoid electrical shock
do not remove covers. Refer servicing to qualified personnel only.
This unit is fitted with a standard fused IEC mains power socket. The unit contains a switch mode
power supply that automatically adjusts itself to 50 - 60Hz mains supplies in the 100V to 240V
(±10%) AC range. This information is printed on the rear of the unit, below the mains inlet socket.
Before connecting this unit to the mains supply, ensure that the fuse fitted is the correct type and
rating as indicated on the rear panel.
For safety reasons the mains earth lead should never be disconnected. In the event of ground loop
problems, disconnect the signal screen at one end of the connecting cables – note that this can only
be done when the unit is used within a balanced system.
Installation Considerations
Location: Do not install this unit in a location subjected to excessive heat, dust or
mechanical vibration. Allow for adequate ventilation around the unit, making sure
the unit’s fans and vents are not obstructed. To prevent excessive heating of the
unit, avoid mounting the unit directly above power amplifiers or other devices
that radiate significant amounts of heat. Where necessary use fan cooled racks.
Cables: To ensure correct and reliable performance, this product should only be used with
high quality, screened twisted pair audio cables, terminated with metal bodied
3-pin XLR connectors (Pin 2 Hot).
Electric Fields: Should this product be used in an electromagnetic field that is amplitude
modulated by an audio frequency signal (20Hz to 20kHz), the signal to noise ratio
may be degraded. Degradation of up to 60dB at a frequency corresponding to the
modulation signal may be experienced under extreme conditions (3V/m, 90%
modulation).
After Unpacking
Please retain the original packing for use should you need to transport or ship this unit.
Please inspect the unit carefully for any signs of damage that may have occurred in transit and notify
the courier immediately if you feel that any damage has occurred.
