Easy Maintenance of Luminance
Level
During long periods of usage, users commonly have to
adjust the luminance level of their projector, as Xenon
lamps typically get darker over time. The SRX-R320 has a
convenient function to help users know when to make such
adjustments. It allows users to set a standard luminance
level, and displays an alert message on the LCD screen of
the projector when the value changes from the standard
level. With this feature, proper and timely maintenance of
the luminance level can be performed.
Automatic Lamp Power Calibration
Function
When switching the aspect ratio of projection from
CinemaScope to VistaVision and vice versa, the luminance
levels happen to change. To maintain a constant
luminance level even after making these changes, the
SRX-R320 can automatically calibrate the luminance level
by controlling the lamp output power.
Air-flow Sensor for Reliable Cooling
The SRX-R320 has a chimney on top of the unit that expels
warm air, thereby keeping the projector unit cool. The
chimney has an air-flow sensor that measures the amount
of discharged air. When the projector is powered on from
Standby mode, the air-flow sensor operates automatically.
If the value does not reach a normal level, an alert
message is displayed on the projector’s LCD screen.
Thanks to this function, the operator can immediately
take proactive maintenance action, allowing for reliable
projector cooling.
Power Supply and Control of
External Ventilation Fan
To efficiently discharge warm air from the unit, the chimney
of the SRX-R320 projector must be connected to an exhaust
duct with a ventilation fan. For optimum reliability and
effectiveness, the projector supports an Interlock interface,
which enables the SRX-R320 to operate this external
ventilation fan. The projector can supply power to the fan
and control its operation – the fan works when the projector
is in Lamp ON mode or Standby ON mode.
Anti-tamper System
The SRX-R320 is designed to be highly secure. It does
not have screw holes, and requires physical keys to open
the enclosure. This body structure meets the anti-tamper
requirement of the DCI. Even if the enclosure is opened
with the physical keys, anti-tamper sensors will trigger the
LMT-300 Media Block to immediately start recording logs for
further safety. In this case, the projector also deletes Key
Delivery Messages (KDM) automatically, so that DCP files
cannot be played back.
SRX Controller Software
The SRX Controller software* is a convenient tool for system
integrators to set up and maintain the SRX-R320. This runs
on a PC** connected to the projector via the RS-232C
interface, and features intuitive GUIs that enable easy
setup and adjustment of the projector. A comprehensive
range of setup parameters including input configurations,
colorimetry controls, installation adjustments, and
maintenance settings can be controlled via this software.
For example, it allows operators to easily verify a lamp’s
operating time. Plus, the versatile projector functions
such as Squeeze Mode, Color Space Conversion (CSC),
and Zoom/Focus Memory can also be controlled via this
software.
