Audison SRx 1D D Class, mono amplifier D Class, mono amplifier, able to deliver 1000 W into 1 Ohm. Compatible with factory OEM car audio systems, thanks to the Speaker-In hi-level input and Signal Sense turn-on/off features. The SRx 1D can also generate a PRE-amp output signal to accommodate system expansion. With the SRx 1D, Audison introduces the “Amp Chain Mode” function. Inherited from the LRx line, this technology provides the ability to “cascade” many amplifiers together, extending the available power to infinite levels, as well as controlling the whole group of amplifiers through one set of controls found on the appointed “master” amplifier..
