DTS Timecode Preamplifier DTS Model E376
Page 2 of 18
INTRODUCTION
The E376 is an accessory to the DTS system and is designed to optimize the readability of DTS
timecode that is not recorded in the standard manner. Typically, DTS timecode is recorded with
a DTS exposure head and printed on either 35mm or 70mm film. These tracks are easily read
with the standard DTS timecode reader head (TCRH). However, when DTS timecode is
recorded on videotape or any other media, there is potential for readability problems such a loss
of low frequency or incorrect level. The E376 is able to optimize any DTS timecode source for
flawless playback in a DTS digital system when the use of a DTS timecode reader is impractical.
DTS 16MM
When using the DTS system with 16mm film, the standard optical sound track is not printed on
the film. Instead, DTS timecode is printed in the optical sound track area and read by the
projector’s standard optical head. Just like DTS 35mm film, the soundtrack is contained on DTS
CD-ROMs and played on a DTS player. For DTS 16mm film, the E376 is standard equipment
and is designed to be a permanent install. The E376 allows you to change between standard
16mm optical and DTS digital playback.
Generally, the audio output of the projector is sent directly to the cinema processor for
distribution in the auditorium. The E376 is installed between the projector’s sound optics and
the DTS player. For DTS playback, the E376 is switched into the Active Mode. This mode
“conditions” the timecode from the 16mm optical sound head and routes it to the DTS player.
“Conditioning” of the timecode includes adding a low frequency boost, if needed, and ensuring
an output of 4-volts peak to peak. When the E376 is switched into the Bypass Mode, the
standard optical signal is routed directly to the cinema processor without any loading on the
audio line.
SPECIFICATIONS
J1 and J2 source inputs are typically from the projector’s sound head at either cell or line level.
There are dedicated connectors for up to two projectors (or sources). JP2 &JP3 jumpers on the
E326 board must be set for the input level (“CELL IN” or “LINE IN”).
yCell input is from 7mV to 200mV RMS.
yLine level input is from 240mV RMS to 7.74V RMS
Power input is 5V DC and comes in at J4 when connected to the DTS digital player’s
TIMECODE connector(s). Pin-outs for the timecode cable is shown on D477 (page 14).
J1 and J2 signal outputs are typically connected to the cinema processor. When in “BYPASS”
the J1 & J2 source inputs are routed directly to this output. When “ACTIVE”, there is no output
at these connectors (to ensure that timecode signal is not heard in the auditorium).
Timecode signal output connects to the timecode input of the DTS player. When in “BYPASS”,
the TCRH input(s) is sent directly to this output. When “ACTIVE”, the conditioned timecode
signal from J1 & J2 is sent to the DTS player.
