The ZPR68-10 is an extremely versatile, rack-mountable Pre-Amp A/V distribution system, distributing up to eight source components through six zones. When combined with EXP9 expansion modules (see below), the ZPR68-10 can be used to control distribution to up to 24 separate zones. Each zone output can be individually pre-programmed to achieve proper volume and tonal balance to compensate for the speakers and acoustics in each zone. The ZPR68-10 is controllable by either IR or RS232 serial commands through any of Xantech's keypad control systems, including SmartPad LCD™ Touchscreen Controllers, SmartPad3™ keypads, or WPK Waterproof keypads.
