Figure 21. Configuring Standby Settings
See the SIS command, Standby
Standby Selection (via SIS or Control System):
Mode 0: When the amplifier is in Standby Mode 0, the Auto-Standby Timer is disabled
and the amplifier does NOT automatically enter standby mode when no active signal is
present on any amp channel for 25 minutes.
Mode 1: When the amplifier is in Standby Mode 1 (default), the Auto-Standby Timer is
enabled. The amplifier remains active while there is an active signal on any amp channel.
The amplifier enters standby mode if no active signal is present on any amp channel for 25
minutes. It returns to active upon detection of signal on any amp channel. When the SIS
command is sent, the timer resets and the amplifier goes into power save state 1.
Mode 2: When the amplifier is forced into Standby Mode 2 via SIS, DSP Configurator, or
a control system, the unit remains in standby until the amplifier is placed into Standby Mode
0 or 1 the same way, regardless of signal presence.
Mode 3 (not accessible via DSP Configurator or SIS): This mode occurs when the
amplifier begins in Mode 1 and there is no active signal present on any amp channel for
25 minutes. In this mode the amplifier is in standby and can be taken out of standby via an
active signal on any amp channel, DSP Configurator, or SIS.
Mode 4 (not accessible via DSP Configurator or SIS): When the amplifier is forced
into standby via the STANDBY port (contact closure), it remains in this state until the contact
is opened. Once opened, the amplifier returns to its last known standby state. This function
overrides all other standby conditions.
NOTE:
• In Standby mode, the line and Dante outputs are muted.
• It is important to note that the auto-standby function relies on active signals that
are routed to the amplified outputs. Signals that are routed only to the line or
Dante outputs, but not the amplifier outputs, do not prevent the unit from going
into auto-standby due to inactivity.
• For applications where the line and Dante outputs may be used independently
during long periods of no amplifier activity, such as when the unit is being used as
both an amplifier and off/on-ramp to the Dante network, the auto-standby timer
must be disabled, and the amplifier must not be forced into Standby mode.
