To calculate the maximum heat emission value when installing the ampliers in rooms with an air-conditioning
system, please refer to the Current Draw and Thermal Emissions specications provided in the Appendix
(section 6.4).
3.4. Operating Voltage
All C…X ampliers have a universal power supply that accepts mains voltages from 100-240 V (+/- 10%) @
50 or 60 Hz. An IEC male receptacle is provided on the rear panel of all ampliers. The IEC cord included with each
amplier has a male plug appropriate for the power receptacles in the country in which it was sold. If substituting a
different IEC mains cord for use in another country, use only a cord that meets or exceeds the power rating of the
originally supplied cord.
Once a suitable AC supply is connected, the amplier can be turned on using the front-panel power switch. The
amplier then goes through a soft-start sequence as it self-checks its circuits. The fans will blow at high speed
before dropping to idle, and the “power” LED will illuminate.
Inrush power is controlled and limited during “soft-start”, enabling multiple ampliers to be powered up
simultaneously with no danger of overloading the mains power circuit.
If you are not 100% condent of your competence to replace the mains plug, engage qualied personnel to do the
job.

3.5. Grounding
There is no ground lift switch or terminal on the C Series ampliers. The signal ground is always oating, via a
resistor, to chassis and therefore the grounding system is automatic.
In the interests of safety, never disconnect the earth (ground) pin on the AC power cord.
Use balanced input connections to avoid hum and interference.
