Audio by Van Alstine has always
provided maximum value, and one of
the ways we accomplish this is by
leveraging our designs. Instead of
cranking out minutely different enclosures
for each model, we carefully crafted
two durable mechanical enclosures
and control function sets. The only
difference between the audio cards
going into a SL or EC chassis is the
presence of tone control circuitry.

Mute
|
Logic-driven relay output mute circuit to eliminates any
potential annoying thumps from the preamp and any upstream
equipment connected to the same switched power strip. Protects
against sudden accidental turn-offs like power failure. The
relay isn’t in series with the audio circuit so contact
points can’t cause signal degradation.
