High 2000:1 Contrast Ratio
The SRX-R220 and the SRX-R210 offer a high contrast ratio
of more than 2000:1* through the use of Sony's unique
SXRD device and proprietary optics. The SXRD imaging
device itself achieves a contrast ratio of over 4000:1.
This stunning picture quality makes the SRX-R220 and
SRX-R210 ideal for cinema exhibition.
The high contrast ratio has been achieved through three key
technologies - the 'Vertically Aligned Liquid Crystal' system,
an extremely thin liquid crystal cell gap, and a new optical
path design.
* The contrast ratio is measured from a screen offering a gain of 1.0.
Xenon Lamp Provides Highly Bright
and Pure Light Source
The SRX-R220 provides a high brightness of 14 ft-L* on a
20-meter (65.6-foot) wide screen, and the SRX-R210 provides
the same brightness on a 17- or 14-meter** wide screen
using a single Xenon lamp.
A Xenon lamp, standard in all film projectors, provides pure,
accurate color tonal reproduction essential to meeting the
stringent requirements of digital cinema. The SRX-R220
utilizes a 4.2 kW Xenon lamp, while the SRX-R210 uses
either a 3.0 kW** for a maximum of 13000 lumens or a
2.0 kW** Xenon lamp for 8000 lumens. Lamps are available
from Sony or many other lamp manufacturers.
* Measured at the screen center of a full pixel size (4096 x
2160) projection with X=3794, Y=3960, Z=3890 white and
a screen gain of 1.8. A ft-L (foot-lambert) is a unit of measurement
for luminance. One foot-lambert equals 3.4262591 candelas
per square meter.

Variety of High-quality Lenses
Five optional zoom lenses are available for the SRX-R220
and SRX-R210. All lenses utilize very large glass optical
components that contribute to minimizing the optical vignetting
(darkening in the corners of the image) that typically occur on
smaller projector lenses, while maintaining the highest possible
values of MTF (Modulation Transfer Function). With these
features, the optical systems of the SRX-R220 and SRX-R210
have the capacity to reproduce resolutions higher than 4K,
which is necessary to project 4K content exactly as the artist
envisioned. In addition, these lenses are designed to minimize
chromatic aberrations using Sony's advanced optical technology.

Variety of Interfaces
The SRX-R220 and SRX-R210 support a wide variety of
signal formats including images using the 12-bit X'Y'Z'
signals that are stipulated in the DCI specification. 10-bit
4:4:4 RGB and 10-bit 4:2:2 YPbPr signal formats are also
supported for playback from other alternative sources.
• Two channels of SRLV which are used for connection to
the Image Media Block (for 4K exhibition).
• A dual-link HD/DC-SDI input that accepts any of the
following signals: SMPTE 372M dual-link HD-SDI (4:4:4),
SMPTE 292M HD-SDI (4:2:2), dual-link DC-SDI (RGB 4:4:4),
DC-SDI (YPbPr 4:2:2), or 12-bit (X'Y'Z' 4:4:4) signals (for
2K projection or HD projection).
• A DVI interface that accepts DVI signals for up to 2048 x
1080 at 60 Hz.
*The DVI input does not support HDCP or HDMI format signals
