4.2.3 Audio settings Tab
The PWR-DSP1 includes an embedded Digital Signal Processor (DSP) used to perform basic signal processing such as
filtering, gain control, equalization, dynamic range compression and time alignment.
In ONLINE mode (i.e. selecting an actual unit from the device tree) all changes are performed real time and
automatically saved in the flash memory of the PWR-DSP1. Settings are automatically reloaded at next connection.
In OFFLINE mode, the configuration needs to be saved before closing the software.
4.2.3.1 Amplifier ON/OFF and Master Mute
The PWR-DSP1 can be remotely turned ON/OFF to save power or audio muted (ON/OFF). See below icons.
4.2.3.2 Amplifier monitoring
At the bottom of the interface, the Amplifier monitoring section indicates real time/live information:
- Clipping indicators when the amplifier output peak voltage/current exceeds the specified values.
- Recorded temperature of the amplifier in degree celsius
- Master volume (Potentiometer at back of unit) position in %
- Temperature reduction protects the amplifier during over-temperature conditions. See page 8 for more
information on limits. Two potential configurations:
o Thermal reduction ON (Box un-ticked and default state): Limiting is engaged after the powerstage,
transformer or heatsink temperature has reached it's specified thermal limiting temperatures. After
limiting is engaged, the amplifier will find its thermal equilibrium.
o Thermal limiter “OFF” (Box ticked): The amplifier disables (Mutes) for a period of time and
automatically restarts , after the powerstage, transformer or heatsink temperature have reached
the specified thermal start-up temperature.
