Liquid Cooling Keeps Panasonic Projectors Quiet

Panasonic is preparing to bring the new DZ780 DLP projector series, which was introduced at ISE (Panasonic Emphasises Strength & Reliability), to market in April. These are low-noise 1DLP models with dual lamps. They are intended to be used 24/7, in public display and signage environments, as well as rental and staging.

Instead of fans, the DZ780 models (PT-DZ780, PT-DW750 and PT-DX820) use a filter-free design and a liquid cooling system. Operating noise is thus lowered to 30dB at full lamp power. Thanks to the use of dual lamps and ‘Relay Mode’, the projectors are able to operate continuously, even in the event of a lamp failure.

Warping and blending is supported, with colour matching and automatic screen adjustment. Additionally, each model features Panasonic’s Digital Link (HDBaseT) technology and DICOM Simulation mode.

Despite using standard (310W) lamps, the projectors can be used in any orientation (360° projection). Lamp life is between 4,000 and 6,000 hours, with brightness levels of 7,000 lumens (PT-DZ780 and PT-DW750 and 8,200 lumens (PT-DX820). Resolution is 1920 x 1200 (PT-DZ780), 1280 x 800 (PT-DW750) and 1024 x 768 (PT-DX820).

The projectors have a powered zoom and focus, with throw ratios of 1.7 – 2.4:1 (PT-DZ780) and 1.8 – 2.5:1 (PT-DW750 and PT-DX820). Image sizes are 50″ – 600″. They also have +/-40° vertical and +/-15° horizontal image correction.

Each model features HDMI, DVI-D, VGA, component and RJ45 inputs. The PT-DZ780 adds a BNC x 1 input, supporting 3G/HD/SD-SDI.

The projectors measure 498 x 521 x 175mm and weigh 17.6kg. They will be available in April, for €9,065 (PT-DZ780) and €5,550 (PT-DW750 and PT-DX820).
