Xantech ZPR68 6-Zone 8-Source Remote Preamp. Six individual IR inputs allow independent zone control of the six built-in audio/video preamps. Compatible with all Xantech infrared receivers and keypads. The same IR system controls all external zone components as well; such as VCRs and laser disc players; using Xantech 282/283 series mini emitters or 794/797 interface modules. Each zone section of the ZPR68-10 contains its own audio/video preamp with remote controlled bass; treble; balance; volume; mute and input select for up to 8 common sources. Each zone output can be individually pre-programmed to achieve proper tonal balance to compensate for the speakers and acoustics in each zone. Each common source can be IR controlled with the use of external Xantech 282/283 series mini emitters or 794/797 interface modules. Each emitter output is individually adjustable for high or low IR level. The ZPR68-10 has the capability to link with the EXP9 expansion module for up to 15 zones total. (All with proper audio and video impedance matching.)
