Audio Example 4

Output 1 drives a 1080p60 HDMI projector without audio capability, and output 2 drives an HDMI amp. In

addition, the amp’s HDMI output drives a 720p (max) LCD TV. When watching the projector (1080p60),

Output 2 should have audio only since the TV cannot accept 1080p60. When you watch TV you would select

720p video output, and turn on the video output on HDMI Output 2. One option is to set MEMA to output

1080p (and disable output 2 video), and MEMB to output 720p on both outputs. Audio can be set as:

When selecting specific audio modes, the up and down arrow keys select an entry and the right arrow key is

used to turn that mode on or off.

Input Memory Specific Audio EDID

If an input, or input memory, requires a specific EDID, it can be configured in the audio setup menu. Each

input memory can be configured to use the global audio EDID, or a specific list of audio modes to report

back to the source. The command is:

Section 7 - Calibration

Your theater system needs to be calibrated. To brighten the image in the show room, most display

manufacturers intentionally change the display calibration away from industry standards. Unfortunately most

displays do not have the controls necessary to undo these errors, and even many of those with calibration

controls are not mathematically correct, making proper calibration impossible without an external calibration

device such as the Radiance.

Correcting these intentional errors, and other unintentional errors, so the image appears as the director

intended, is a primary function of the Radiance. The Radiance has a host of features dedicated to this task.

It is recommended that a professional calibrator be hired to perform the calibration. An experienced

professional calibrator has the necessary tools and experience to extract the best performance from your

theater. However, you can improve your picture without hiring a professional if you prefer. You will need to

learn how to use the Lumagen test patterns. Then you need to spend time learning how various calibration

controls interact and how they affect image quality, with the most important being proper adjustment of the

Black level in the display/projector.
To understand Radiance calibration, it is important to note that setup and calibration parameters are split

into “input memories” and “output configurations.” Input memories are for source specific setup and

calibration. Output configurations deal with display setup and calibration. These are covered elsewhere in

this manual.
It is recommended that the internal Lumagen test patterns be used to calibrate the output configuration.

This will assure that any variance between sources do not affect the calibration of the display.
The recommended Lumagen calibration sequence is discussed in TechTip 2 on the Lumagen support

“Manuals and TechTips” page at

. Please check

out this and other TechTips for information on setup and calibration.
