Setting the Output Mode

The NetPA U 2002 SB output mode is configured via DSP Configurator and the selection is passed to the amplifier. There are six
selectable modes that are divided into two stereo modes and four bridged mono modes.
• Stereo Modes (8 ohm/4 ohm) — Each channel of an output pair behaves independently, and each input can be routed to
any output.
Bridged Mono Modes — There are four bridged mono modes: two low-impedance (8 ohm and 16 ohm) and two high-
•
impedance (70V and 100V). The second amplifier output is not user-controllable in DSP Configurator.
8 ohm bridged — This mode bridges the output pair and sets it for an 8 ohm load.
•
16 ohm bridged — This mode bridges the output pair and sets it for a 16 ohm load.
•
70V — This mode bridges the output pair and sets it for a 70V load.
•
100V — This mode bridges the output pair and sets it for a 100V load.
•
Bridging occurs in the amplifier. The positive pin on Channel 1 becomes the positive pin of the bridged output, and the positive
pin on Channel 2 becomes the negative pin of the bridged output.
When the amplifier is set to bridged mono mode, DSP Configurator deletes the Channel 2 amplifier output signal chain, including
mix points and output processors.
In the 70V and 100V modes, an 80 Hz, 12 dB/octave high-pass filter is applied to the output filter block by default. The user can
change the frequency and slope of this filter. In all other modes, the high-pass filter is not applied by default.
Configuring the Output Mode
