General Notes about Usage

If you turn off the VSi75 wait at least five minutes before turning it on again.
This brief cool down period will reduce stress on the output tubes and
potential damage to them.
Audio Research does not recommend leaving your VSi75 on 24 hours a day
as is the custom of some listeners to achieve maximum sonic performance
on demand. While this is often recommended for solid-state equipment,
Audio Research does not recommend this procedure for vacuum tube
power amplifiers. (2,000 hours of tube life will pass by in 84 days!)
CAUTION: Do not turn up the Volume control beyond normal listening
levels when the VSi75 is in the "mute" position. Always turn the Volume
control down when changing program sources, even when it is muted.

Resetting Controls

To avoid discharging static to the VSi75 controls, contact another surface
(such as a metal equipment rack) to drain away the charge before touching
the VSi75. If a static charge should "lock up" the microprocessor making the
front panel controls inoperable, unplug the VSi75 from its power receptacle.
After waiting two minutes, plug in the VSi75 and power it up with the rest
of the system; the controls should resume normal operation. If the problem
persists, contact your dealer or Audio Research Customer Service at 763-
577-9700.
