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
age over time. The SRX-R220/SRX-R210 has a convenient
function to help users know when to make such adjustments.
The supplied SRX Controller software 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 will change.
To maintain a constant luminance level during these changes,
the SRX-R220 and SRX-R210 projectors can automatically
calibrate the luminance level by controlling the lamp output
power. Users can set their desired luminance level using the SRX
Controller software for this operation.
Key Lock System
The SRX-R220 and SRX-R210 are designed to be highly secure in
response to DCI requirements. They do not have screw holes
and require physical keys to open their enclosures. The security
enclosure meets the SPB-2 anti-tamper regulation stipulated by
the DCI. Even if the enclosure is opened with the physical keys,
an anti-tamper sensor will trigger the LMT-100 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.
