Front Panel Controls, Push-Buttons, Switches and Displays Front Panel Controls, Push-Buttons, Switches and Displays The INPUT switch selects any one of the four DIGITAL INPUTS or the ANALOG INPUT The CHANNEL STATUS LED display indicates which channels are active, depending on the incoming signal; L (Left Front), C (Center), R (Right Front), LFE (Low Frequency Effects), LS (Left Surround), S (Pro Logic Surround), R (Right Surround) The IR (Infra Red) sensor accepts IR signals directly from an HR39/ HR130
Delay Calibration for Center and Surround Channels Delay Calibration for Center and Surround Channels Delay and Level calibration procedures are made relative to the listening area. The ideal listening area is defined as facing directly toward and centered between the front speakers, and in line with the left and right surround speakers. NOTE: Refer to the Front Panel Drawing on the opposite page and Figures 1 & 2 on this page for the following steps.
How to Operate with a C39/MX130 The first time you press the SURR/DELAY push-button the DELAY/VOLUME display will indicate 5, which is equivalent to a 5 millisecond delay which is the factory default setting. This would correspond to a typical listening room where the surround speakers are 5 feet closer to the listening area than the front speakers.

System Level Calibration cont bers, and if decreased shows minus numbers. Calibration levels can be adjusted over a range of plus or minus 12dB. 6. When the test signal switches to succeeding channels, repeat the level calibration process until the test signal volume levels of all the channels are the same. 7. The calibration channel cycling mode can be repeated as often as necessary until you are satisfied that the volume levels of the test signal are the same from all channels. 8.
