Status Possible Triggers
Over Temp
The amplifier has
exceeded the
recommended operating
temperature.

DC Protection
A DC signal has been
detected on an amplifier
channel.
Global Status Section —
• Unit temperature — Displays the internal temperature of the amplifier at a
particular location.
• Power Save State — Indicates the standby state that the amplifier is currently in.
• Active (Auto Timer Disabled) — 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.
• Active (Auto Timer running but not triggered) — 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.
• Standby (SIS triggered) — When the amplifier is forced into Standby via SIS
through DSP Configurator or a control system, the unit does not wake from
standby until the amplifier is placed into Standby Mode 0 or 1 (Active [Auto
Timer Disabled] or Active [Auto Timer running but not triggered], respectively)
the same way, regardless of signal presence.
• Standby (Timer triggered) — The amplifier has entered standby mode
because no active signal was present on any amp channel for 25 minutes. It
returns to active upon detection of signal on any amp channel.
• Standby (Contact Closure triggered) — The amplifier has been forced into
standby via the STANDBY port (contact closure), and remains in this state until
the contact is opened. Once opened, the amplifier returns to its last known
active standby state. This function overrides all other standby conditions.

Possible Solutions
•
•
•
•
•
Verify that the placement of
the amplifier allows for suitable
ventilation and airflow
Avoid placing equipment on
top or below the amplifier.
Verify that the operating
temperature is within the
specified range.
Disconnect power then
reconnect power to the
unit to determine if the unit
immediately goes into standby
upon power up
The amplifier may need to be
serviced.
