(NOTE: SPL readings should be measured unweighted, or C weighted - slow)
Remove the blue cover by unscrewing the two black Philips screws from the front panel. With
ALL power amplifiers turned on, master fader set to reference position “7” and speakers
unmuted, adjust the appropriate “6-TRACK” trimpots on the DTS-6 processor (see Fig 3) to
achieve the specified SPL noted above.
MONO SURROUND
For those theaters with mono surround only, wait for either the left -or- the right surround PINK
noise when adjusting the MONO SURR trimpot for 82dB SPL. Be sure the surround switches
inside the DTS-6 player are set for MONO. See Section 3.2.
NOTE: The STEREO adjustment trim pots are no longer used.

• Index Switch
On some models, there is a small black momentary push button switch located below the
TIMECODE HEAD OFFSET switches (Figure 3). It is commonly called the “index switch”. This
button can be used to increment to the next track being played. This feature works on the DTS
6-TRACK SET UP discs Rev. D and Rev. C only. On shows of serial number 1009 and higher,
the momentary button also bypasses the DTS-6 processor to allow checking of the optical bypass
function.
If your DTS-6 does not have an index switch and you’d like to install one, call DTS and purchase
the D475 kit. This kit has all you need to install the index switch to your DTS-6.
• Automatic Default programming
There are only two choices on the DTS-6 unit: A-Type or SR-Type. The programming is
accomplished via jumpers on DTS external logic boards. See wiring diagrams for more
information.
