The CNXBRMO is designed for use with a Crestron CNX-PAD8A or CNX-BIPAD8 audio distribution processor to facilitate bridging of a CNAMPX-16X60 or CNAMPX-12X60 multi-room amplifier. Bridging allows two adjacent amplifier channels to be combined for increased output power.
The CNXBRMO is designed for use with a Crestron CNX-PAD8A or CNX-BIPAD8 audio distribution processor to facilitate bridging of a CNAMPX-16X60 or CNAMPX-12X60 multi-room amplifier. Bridging allows two adjacent amplifier channels to be combined for increased output power.
The CNXBRMO accepts the stereo signal from a single room output and splits that signal into two stereo outputs, the polarity of one output inverted in relation to the other. These two outputs connect to the inputs of two adjacent stereo channels on the CNAMPX amplifier. Resultantly, the two stereo amplifier channels produce inversely proportionate signals so that the combined output can be used to drive a single stereo pair of speakers with over 200 Watts of output power per speaker.
On either amplifier model, only the first two adjacent channels and the last two adjacent channels are bridgeable. Therefore, no more than two CNXBRMO interfaces may be used with a single CNAMPX amplifier.
The CNXBRMO can also be configured to produce a summed-mono signal to up to four outputs, although the polarity of two of the outputs remains inverted.
