HC5 - QUESTRONIX

Quest AV model HC5
Hum-cancelling
Video Distribution Amplifier

The HC5 Video Distribution Amplifier continues the tradition of solid reliability and professional performance set by our original model HC3 and offers practical features for the Audiovisual, Broadcast and Film industries.

Hum-cancelling circuitry efficiently reduces common-mode interference induced by mains wiring, lighting dimmers, ground loops, audio leakage, etc. without impacting on video bandwidth.

Wide bandwidth, high output drive capability and unconditional stability mean your video will arrive crisp and clean.

Housed in a powder-coated steel case for strength and safety.

Front panel accessible Video Gain and cable EQ adjustments let you compensate for long cable runs and the recessed User Adjustment / Factory Cal. switch is a great way to get back to standard settings in a hurry.

Select from power supply options of 240Vac or 120Vac. The HC5 features low power consumption.

Size of the HC5 has been minimised whilst retaining a convenient layout of controls and connectors.

A real problem solver, the HC5 is indispensable in the Audiovisual and Video engineer's tool kit. The HC5 cancels induced common-mode hum and other interference presenting a clean video signal to five buffered outputs. Featuring accurate, multi-turn user-adjustable video gain and cable equalisation controls, the HC5 has enough gain in reserve to allow compensation for up to 300 metres of 75ohm video co-ax, or to tweak up a poor signal. If you prefer, just switch back to 'Cal' for the gain and equalisation to be returned to factory settings. All connectors are BNC's.

This new model has many useful features such as:- Switchable factory calibrated or user-adjustable gain and equalisation (with LED indicator), new low-profile, compact design. Wide video bandwidth for high resolution video signals. High performance and 24 hours a day, 7 days a week Quest AV reliability. Quest AV VDA's can be found in use in permanent installations, broadcasting, video editing, audiovisual installations, live events, sports arenas, government departments, in fact anywhere a video signal needs high quality distribution.
