The D Series Tesira amplifier is an 'expander' in the Tesira environment. It can be considered a remote analog output, but at very high power. Each channel does have a channel strip of processing in the Tesira environment that contains level, mute, and invert. The amplifier has digitally controlled gain and the ISVPL limiter similar to the PLM range. The amplifier needs to be managed by a Tesira server to get its configuration. In the Servers, you can create DSP functions in its free-wire system.
