Vaddio PreVIEW Quad 4 LCD rack mount monitor features four 4” (10.16cm) high resolution active matrix LCD monitors for exceptional video clarity and color handling. The PreVIEW Quad 4 is a simple and straight forward four LCD rack mount monitor without controls for previewing general shots and areas without the need for extreme detail. All four of the 480 x 234 resolution LCD panels on the Quad 4 have their own input and amplified loop through on BNC connectors for ease of configuring video production systems. Constructed of heavy gauge aluminum and steel, the enclosure is both tough and attractive and can be a tilted +/-25° for setting up optimum viewing angles. The PreVIEW Quad 4 is set-up for auto recognition of NTSC and PAL video formats and unlike many of the rack mount LCD monitors available today, the Vaddio PreVIEW Monitors are both FCC and CE certified.
