Features
THERMAL PROTECTION & AUTOMATIC IDLING CIRUITRY
Thermal protection circuitry is provided for stability and reliability against over-current and over-heating.
Automatic idling circuit is also provided to protect against thermal run-away.
▪ MUTE START SYSTEM
To protect speakers and remove pop noise, start operating after 1 second.
▪ BALANCED INPUT
To allow you to build reliable system, a balanced input is provided to reduce hum pick up from a long distance input cable
and to avoid group-loop problems.
▪ USE OF EMERGENCY BATTERY
You can operate the power amplifier by using emergency battery for unexpected AC power failure.
