Speck Electronics X.Sum - Manual (Page 11)

Chapter 2 Installation & Setup 7
The following information should give you the basics on how to install the
X.Sum mixer and power supply. The proper installation of the X.Sum
requires a clear understanding of audio wiring, AC distribution, grounding,
and shielding techniques.
If the X.Sum is being installed into a larger studio or as a expander to a host
console, it may be necessary to retain the services of someone experienced in
these matters.
One of the primary reasons that the power supply of the X.Sum is external is
to insure that the power transformer enclosed within the power supply chassis
maintains a safe distance from the active electronics of the X.Sum. For that
matter, any device that has a strong magnetic power field should be kept at a
reasonable distance from the X.Sum and its audio cables.
Because the power supply does not use a cooling fan, it is silent and can be
located in the same room as the mixer. It is important that the ventilation
holes are not obstructed and that the unit is operated in free air to prevent
overheating. Allow a minimum of 4”(100mm) of clearance from all
ventilation holes.
The X.Sum's power supply can operate with two mains settings of 115 VAC or
230 VAC 50/60hz. Before switching “on” the power, you should verify that
the voltage setting on your power supply is configured to match the AC mains
requirements of your country. If the AC mains voltage needs to be changed,
this procedure should be performed and checked by a qualified technician.
Before connecting the DC power supply cable to the X.Sum, make certain the
power switch is set to the “off” position.
To connect the power supply to the mixer, fit the circular connector from the
power supply to the chassis mount receptacle on the rear of the X.Sum. The
respective connectors are keyed so the plug and the receptacle can fit in only
one direction.
