3.2.2. A Note about DTS Subwoofer Output

The XD10 subwoofer output level ranges from 20Hz to 120Hz (Coherent Acoustics format), up to 27dB

above reference (85dB).

Check your subwoofer’s specifications to avoid damage to the speaker.

If a subwoofer is driven below its cutoff frequency, its driver(s) may become unloaded. When unloaded,

the voice coil can travel outside of the magnet’s gap, overheating and/or causing mechanical damage to

the speaker. A high pass filter should be installed on speakers with high cutoff frequencies. Contact your

speaker manufacturer for more information.

3.2.3. Mono Surround

The mono surround output is a mix of the left and right surround signals. This “mono” signal is available

ONLY on the mono surround output pin (pin 21) on the XD10's ANALOG OUT (CH 1-10) connector.

1. In theaters with only mono surrounds, select the left surround pink noise and adjust for 76 dBC

SPL in the theater. Note the level displayed on the XD10 screen.

2. Next, select right surround pink noise and adjust the output to the SAME level that the left

surround was adjusted to. The level in the theater should be the same, 76 dBC SPL, as when

playing back pink noise on the left surround channel.

Any future adjustment of the surround levels should be made to both the left and right surrounds equally

to maintain the correct balance of the original stereo surround mix.

3.3. Timecode Reader Sync Adjustment

This adjustment is easily performed using the numbered leader in front of the DTS Demo Reel. (The

demo reel is supplied with the DTS Technician’s Kit, which can be purchased from any DTS dealer.) See

the steps (below on this page).

Additional drawings can be viewed in Appendix B (Installation Diagrams) of this manual.

If you do not have a demo reel, the delay can be calculated by counting the number of picture frames

from the DTS reader head red LED (lens) to the projector’s picture (“film”) aperture. Multiply the result

by 1.25 and subtract 1. Round the resulting number to the closest ¼ (0.25). Set the OFFSET value in the

XD10 System Setup | TC RDR Offset menu to this number.

Example: 27 frames x 1.25 = 33.75

33.75 - 1 = 32.75

Set the OFFSET to 32.75

Remember: When using the counting frames method, frames are counted from the timecode

reader lens to the picture aperture. And the first frame, the frame at the lens, is counted as

zero (0) – NOT as 1.
