23.STANDBY ON/OFF SWITCH: Allows the AT-212 to remain turned ON for limited periods of inactivity without the risk of damaging / over-heating the amplifier tubes. When the Standby switch is in the STANDBY position the AT-212 is in a non- operational setting. When in Standby the Sovtek tubes remain hot and ready for use. This bypasses the time required for the tubes to warm up before use. When the Standby switch is in the ON position the AT-212 is operational and should not be left inactive. DO NOT turn on the AT-212 or have the Standby switch set to ON without it connected to a loudspeaker.
