ETI Sound Systems, INC AT-100 - Manual (Page 5)

1. POWER ON/OFF SWITCH: Turns the AT-100 on and off.
2. STANDBY ON/OFF SWITCH: Allows the AT-100 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-100 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-100 is operational and should not be left
inactive. DO NOT turn on the AT-100 or have the Standby
switch set to ON without it connected to a loudspeaker.
