Specifications

Table 7-1. Q-750d Specifications (continued)

Brightness and Contrast:	Cinema Standards Measurement System (CSMS)
	Specifications
	- Brightness: 29 foot-Lamberts (fL)
	-	Contrast Ratio: 330:1
	These measurements are taken from the projector in a controlled,
	home theater environment. All measurements are made to
	ANSI/NAPM IT7.228-1997 specifications using the Photo Research
	PR-650 SpectraColorimeter and Minolta LS-100 Luminance Meter,
	Video Essentials test DVD and a 1.3 gain, 72-inch wide screen. The
	projector is calibrated to a color temperature of 6,500K and has a
	minimum of 150 hours of usage.
	The foot-Lambert (fL) is the unit of measurement used in commercial
	movie theaters to express image brightness at the screen surface. The
	Society of Motion Picture and Television Engineers (SMPTE) specifies
	16 fL as the target image brightness for film-based projectors using an
	open gate (without film in the projector). More importantly, today
	SMPTE specifies 12 fL as the target image brightness in Digital
	Cinema theaters. The foot-Lambert measurement is dependent on
	screen size, screen gain and projector light output.
	Home Theater Calibration Specifications
	- Light Output: 450 ANSI Lumens
	-	Contrast Ratio: 330:1
	These specifications are obtained by calibrating the projector as
	described above for CSMS measurements.
	Industry-Standard Specifications
	- Light Output: 700 ANSI Lumens
	- Contrast Ratio: 3 settings (Infinity:1, 20,000:1, 10,000:1
	(sequential))
	ColorContrast™
	Colors have up to 50% higher contrast than Mercury or Xenon
	lamp systems.
	These are typical projector brightness and contrast specifications
	found in most companies’ sales literature. Runco includes these
	measurements in its literature to allow for direct comparison with other
	manufacturers’ projectors. These measurements are typically taken at
	9,000K to 13,000K to get expected performance data when the
	projector is used in professional, commercial and industrial displays.
Power Requirements:	100 to 240 VAC (auto-sensing), 50/60 Hz, 140 Watts typical

	Q-750d/CineWide with AutoScope: See Figure 7-2
Weight (including lens):	49.4 lbs. (22.4 kg)
Regulatory Approvals:	FCC Part 15 Class B, CE Class B, UL, cUL, CB, RoHS,
	WEEE, local conformances as required
Limited Warranty:	Two (2) years parts and labor from the date of delivery to the
	end user.
Maintenance:	Zero maintenance, solid state optical path.
