INSTALLING THE SIGMA PREAMPLIFIER
Physical requirements:
1)Provide Adequate Ventilation.
2)The chassis cover will become warm during normal use.
3) This component must be installed in a secure, properly built (and ventilated) stand,
cabinet or enclosure. It could inflict serious injury or property damage if it falls, or
if the stand upon which it is placed tips over. This concern is particularly important
in households with small children who might try to climb furniture.
Basic Hookup:
1)Connect line level inputs (CD, Tape, etc.) to the appropriate RCA input jacks on the
rear panel. With the exception of Phono (when fitted), all inputs are “line level”.
2)Connect phono cables to the rear panel RCA input labeled “Phono.” Connect the
ground wire from the turntable or phono cable to the “Ground” terminal provided on
the rear panel. (See “Phono Section” for cartridge types appropriate for use.)
Connect output interconnects to your power amplifier.
3)Connect the AC power cord to the IEC connector. For best performance, route the
power cord away from signal cables.
4)Before turning the power switch to the “on” position, set output level to zero by
rotating the “Volume” control fully counterclockwise. Note: Mute is automatically
engaged when switching on.
5)Allow the preamplifier to warm up for a minute before you unmute the unit; failure
to wait can cause a transient to be sent through your power amplifier that might cause
damage to your loudspeakers and amplifiers.
6)Always mute the preamplifier before switching it off. The best practice is to also turn
off your power amplifier(s) before turning off the preamplifier.
As with all high performance audio products, the sonic characteristics of all VAC products
will continue to improve during the first several hundred hours of use.
