Bose Pow Configuration Utility User Guide
Settings: Amplifier
The
Amplifier
page allows you to configure the following amplifier settings:
l
Hi Z:
Click either
70V
or
100V
in the toggle to specify the constant voltage mode for the Hi-Z
(high impedance) output of the device.
l
Mute Polarity:
Allows you to establish the polarity for the mute contacts on the rear panel of the
device. Click the toggle to select one of the following options:
-
NO – Normally Open:
indicates that the mute contacts are normally open and a short across the
mute connector will mute all outputs.
-
NC – Normally Closed:
inverts the mute polarity where an open circuit across the mute connector
will mute all outputs.
l
Auto Standby:
Click the toggle to enable or disable Auto Standby mode. When enabled, this option
automatically places the amplifier into Standby mode, allowing the system to consume less power.
When the
Auto Standby
option is enabled, the amplifier is automatically placed into Standby mode
when the audio signal falls below a predefined threshold (-55 dBV) for 20 minutes. The amplifier
automatically exits Standby mode (wakes), within 1 second, when an audio signal above the
threshold is detected.
CAUTION:
Enabling Auto Standby is not recommended when using VOX paging because page
signals may be truncated.
Notes:
l
You can immediately place the amplifier into Standby mode by enabling the
option on the
Summary
page of the
Dashboard
tab.

l
Output Attenuators:
Click the toggle to enable or disable the output attenuators on the rear panel
of the amplifier. When
Disabled
is selected, the output attenuation is locked at its current level.
