amplifiers turned on, master fader set to reference position “ 7 ” and speakers unmuted, adjust the appropriate
trimpots (see Figure 4) on the DTS-6D processor to achieve the specified SPL noted above.

adjusting the

Index Switch
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. C and Rev. DS1 only . On shows of serial number
1009 and higher, the momentary button also bypasses the DTS-6D processor to allow checking of the optical
bypass function.
