Use the longest measured distance as your 0 reference and SUBTRACT each speaker distance from this reference. This result is the number you should enter. For example: If the Left is 10 ft from the primary listening seat and the center is 8 ft, you should enter 0 ft into the left (10 ft – 10 ft = 0ft) and 2 ft (10 ft – 8 ft =2 ft) into the center. Measuring and inputting the distance settings for each speaker is a simple process but is does require the installer to follow a simple procedure. Failure to follow this procedure may result in incorrect settings being input in the EQ. 1. Measure the distance from each speaker to the central, or #1, microphone. This should be the center of the listening area most likely. 2. Write down the distances for each speaker. 3. Using the longest measured distance subtract this from all the other distances. 4. Enter the result into each speaker distance. • Measurements can be in Feet and Inches or Meters • When entering feet and inches use the format of XX’yy” where XX is feet and yy is inches. Use 0” if the distance is 0 different and 0’yy” if the distance is under 1 foot. Note: When measuring and inputting the speaker distances into the SDEC DO NOT input the measured distances. Type in the correct distance offset in this box. Enter as feet and inches or meters and the correct millisecond delay will be calculated Figure 13. 14SDECX000DACSCalibrationManualv1.0.doc 6.3.4 Channel Output Use each output to adjust each channel to give the same output level using an SPL meter. 6.3.5 Level Matching Multiple Surround and Subwoofer Channels The SDEC-4000 has multiple outputs for Subwoofers and Side Surrounds. These will need to be level matched to each other before final output levels are set. 1. Using the internal noise test of the SDP test each output individually. It will be necessary to mute the output you are not testing. Make sure the Trim Link is off (not RED). 2. Once you have set each to the reference level (75dB) enable the Trim Link feature so that the led turns RED. 3. With all the multiple channels un-muted test together and adjust the output to reach the same reference level. You will now have an output that has all the multiple channels level matched and the overall output set to the reference level. Figure 14. 15SDECX000DACSCalibrationManualv1.0.doc 7 Speaker Sound Check Use the circulating noise generator of the Surround Processor to confirm that all channels have output and that each speaker is connected to its corresponding channel. 8 Speaker Phase Test This procedure uses the Surround Processor to route the phase tester's output to the appropriate channel for test. Using a "Y" adapter, connect the phase tester's output to both channels of the TAPE or AUX input or any available analog input. Select the input making sure that the processor is set to the analog input you have selected, use the Surround Processor's volume control to set the test level. Select PARTY or 5/7 Channel Stereo Mode to route the test signal to all speakers. It may be necessary to adjust the volume or mute certain channels to get a clear and accurate test result. 8.1 Main Speakers Use the phase tester to confirm the following driver polarities of the L-C-R and subwoofers Synthesis Everest: L-C-R UHF (+) L-C-R Horns (+) L-C-R Mid-bass drivers (+) Subwoofers (+) Synthesis K2 S9800: L-C-R UHF (+) L-C-R Horns (-) L-C-R Mid-bass drivers (+) Subwoofers (+) Synthesis Atlas SK2-1000: L-C-R UHF (+) L-C-R Horns (-) L-C-R Mid-bass drivers (+) Subwoofers (+) Synthesis One Array: L-C-R UHF (-) L-C-R Horns (+) L-C-R Mid-bass drivers (+) Subwoofers (+) Synthesis Two Array: L-C-R UHF (-) L-C-R Horns (+) L-C-R Mid-bass drivers (+) Subwoofers (+) Synthesis Array Three: L-C-R UHF (-) L-C-R Horns (+) L-C-R Mid-bass drivers (+) Subwoofers (+) 16SDECX000DACSCalibrationManualv1.0.doc Synthesis Four: L-C-R Tweeters (-) L-C-R Mid-range (-) L-C-R Mid-bass drivers (+) Subwoofers (+) Synthesis Project Array: (except Array 880) L-R UHF (+) L-R Horns (+) L-R Mid-bass drivers (+) Subwoofers (+) Array 880 C UHF (-) C HF (+) C Mid-bass drivers (+) 8.2 Surround Speakers 8.2.1 S4Ai configured as Bipole (default) The S4Ai can be used as a bipole, dipole or a direct radiating point source speaker. The default as shipped is bipole. Other bipole speakers would be similar. Figure 15. 8.2.2 Dipole Surrounds Regardless of model there is one standard for phase configuration of Dipole surrounds. Figure 16. 8.2.3 Direct Radiating Point Source Surrounds are two slide switches and a pulse indicating LED. Slide the ON/OFF switch to the ON position and the output selector to the LO position. You should now hear pops at one second intervals from the speaker under test. If a higher level is required, set the output selector to HI. 8.3.2 Cricket-R The receiver contains a microphone and phase analysis circuitry. Positive polarity is indicated by a green LED, negative by a red LED. Two input connectors and the microphone are located on the rear ...
