Once all connections have been made and conﬁguration options selected, Inca 500

ampliﬁers are ready for use. If an input signal above -60dB is present on any input, the

front panel Input and Standby indicators will illuminate green to indicate normal ampliﬁer

operation. Audio will be heard from any connected speakers.

Note: Inca 500 ampliﬁers will not switch on from Standby Mode unless an input signal is

present, a network ‘ON’ command is received, or an external standby switch (or 12V trigger)

is operated. Standby behaviour can be conﬁgured via the Power Management menu of the

Settings Tab.

Ampliﬁer outputs will mute if no input signal is present for 5 minutes, and the ampliﬁer will

switch automatically to Standby Mode if no signal is present on any input for more than

15 minutes. Alternative standby and mute delay times can selected via the Settings Tab.

Ampliﬁer cooling fan speed is temperature controlled. The fan will switch o when the

ampliﬁer enters standby mode.
