On the front plate of the GOLDMUND TELOS 350 amplifier you will find one POWER
green light, one LOCKED orange light and one ERROR red light.
When first connected to mains power the 3 leds flash ones to indicate AC line detected.
The orange led will flash twice (equal time on and off) to indicate the initialization, at the
end of this sequence, the amplifier enters in STANDBY mode. The orange led flashes
slowly.
Once in STANDBY mode, a short key press (<1 second) switches the amplifier ON, the
green led will flash five times indicating the initialization in POWER UP mode. The green
led is permanently illuminated in this mode.
If the digital input is not used, the orange led is turned off, showing there is no lock and the
amp remains muted until a lock is found. With a digital input, the amp is immediately
operational and the orange led illuminated
The amp may be returned to STANDBY mode with a short key press. A long key press (>2
seconds) takes the amplifier in POWER OFF mode.
If an error is detected the red Led will be illuminated. Once the cause of the error has been
removed, the amplifier can be returned to STANDBY mode with a long key press.
These security features are provided to reduce the risk of accidental POWER ON or
POWER OFF and to protect the amplifier in ERROR mode.
