ETI Sound Systems, INC AT-100 Manuel D’Utilisation

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.
