The MON-1/M 8 Channel Dolby E, Dolby Digital & PCM Audio Monitor from Wohler is a powered eight channel audio monitor designed specifically for decoding, processing, and monitoring Dolby E, Dolby Digital, HD-SDI, SD-SDI, and AES/EBU audio signals. The unit occupies 2U of rack space.
Eight, high-resolution LED bar graphs offer superior visibility and accuracy of audio levels. Fifty three bicolor segments simultaneously display signal levels according to PPM and VU standards. The front panel LCD display provides Mode and Audio Select information at a glance.
The speakers and amplifiers are arranged in the popular Wohler bi-amp summed bass stereo configuration: bass frequencies from all selected channels are summed into a 20W amplifier, which drives the woofer. The two side-channel amplifiers and speakers reproduce in stereo only mid and high frequencies. Please note that the middle speaker, the woofer, is not a dedicated center or LFE speaker. The unit also features a headphone output, which mutes the speakers while in use.
