Protection
Turn‐On‐Turn‐Off muting
For about four seconds after turn‐on, and immediately at turn‐off, the amplifier outputs are muted.
Short circuit protection
A short circuit protection system safeguards the amplifier's output devices under short circuits and other stressful loads. It is
completely inaudible when inactive. In the event of a short circuit condition, the red Protect LED will be illuminated. The amplifier
protection has an auto reset mode which will attempt of reset the amplifier for normal use after 2 seconds. If the short circuit is
still present the amplifier will attempt to reset every 2 seconds until the short is removed.
Thermal protection
The VIA amplifiers use a continuously variable speed fan to assist cooling (the fan speed changes in response to the amplifier's
cooling requirements). If the heatsink temperature reaches above 85°C the thermal sensing circuitry will operate the Protect
circuitry and mute each channels power section. Once the heatsink has cooled below 85°C the amplifier will automatically come
out of protect mode
DC fault protection
If DC or excessive subsonic energy appears at a channel output, an instantaneous protection circuit will mute all channels of the
amplifier.
Input / Output protection
An ultrasonic network decouples RF from the outputs and keeps the amplifier stable with reactive loads.
