Configuring standby mode
The loudspeaker has an automatic standby function that is dependent on the input signal . It
switches the loudspeaker into power saving mode when it hasn’t been used for a period of
time . The standby function is only enabled when the INPUT SELECT switch is in the ANALOG,
S/PDIF L or S/PDIF R position . When the switch is in the AES67 position, the standby function
is disabled .
Standby means that the network interface, signal processing circuitry and power amplifiers
are all powered down . Standby mode is automatically deactivated when a sufficiently large
audio signal is detected at the input . The time taken to resume normal operation and hear
sound is 5 seconds .
When the INPUT SELECT switch is in the ANALOG position, the loudspeaker switches to standby
mode after 90 minutes without an input signal or with only a very low input level .
For the standby function to be activated, the incoming signal must not cause the loudspeak-
er’s output level to exceed an internally specified threshold for the specified standby time .
This therefore depends on both the amplitude of the input signal and the level setting on the
loudspeaker itself . The level threshold is 20 dB SPL at a distance of 1 m in free field conditions .
Even if there is no input signal, however, interference and crosstalk in the signal source or
input line can cause the loudspeaker to wake up or prevent the loudspeaker from switching to
standby mode in the first place .
If the INPUT SELECT switch is in the positions S/PDIF L or S/PDIF R, the loudspeaker switches
to standby mode after 90 minutes when there is no digital clock signal or the digital input
signal is muted . In these modes, the loudspeaker wakes up when the digital signal reappears .
Standby mode will remain active as long as the sampling rate of the applied S/PDIF signal
does not change .
When switching to standby mode, a slight pop may be heard .
Standby in backplate mode
X
Set the CONTROL switch to
Local
.
The idle time for standby mode is 90 minutes .
The output level depends on the positions of the OUTPUT LEVEL switch and the INPUT GAIN
knob on the back of the loudspeaker . Set them as required for your setup .
Standby in network mode
X
Set the CONTROL switch to
Network
.
You can disable automatic standby mode using the
