1 Introduction

1.1 OVERVIEW

This manual describes the configuration and operation of the DTS Professional Audio
Equipment, which includes the CAE-4 Professional Encoder, the CAD-4 Decoder, and the
E175-01 DVD Timecode Controller. This is the r eference equipment t o create DTS bitstreams
from 5.1 source mate r ial for DVD-Video and CD.

The manual explains the general requirem ents f or encoding. It also outlines specif ic product ion
scenarios. The scenarios serve as examples for conf iguring production environments.

Operating software is included in this pack age (on CD-ROM), and it runs on Windows 95, 98,
2000 or NT systems. Use of the DTS Record Panel is described in Section 5 of the manual. At
the end of each project, always comply with standard industry practice f or Qualit y Control (QC) .
It is strongly recommended that QC always include critical listening of encoded material to
verify acceptability of content for end users.

A software playback panel will be available in the upcoming months. Until then it may be
necessary to use a third party program (ie; Sound Forge) for play back of DTS files directly
from your computer. A t ypical application is illust rated in Figure 6.

The E175-01 DVD Timecode Controller is described in Sect ion 6 of this manual. It is used to
sync picture content with audio content for DVD-Video applications, enabling users to select an
encoding project start and end time.

Minimum Computer Requirements to oper at e the DTS Record Panel software:

1. Windows 95, 98, 2000 or NT

2. A PC with a minimum of 64 Mbytes of memor y, a separate system drive and a data drive
with 4Gbytes (content dependent) free on hard dr ive.

3. Your will need to turn off background prog rams running (ie; screen savers, virus scan – off ,
etc). This will insure a successful DTS encode bitstream capture into the computer.

4. It is suggested that in AGP video card be used where possible.

Sound Cards tested and verified for use with DTS Pro Audio Equipment:

1. SEK'D-PRODIF 96 Pro

2. Lynx One

3. Zefiro ZA2

4. MOTV 308/PC1324

1.2 REGULATORY NOTICES

1.2.1 Emi Notice

This equipment has been tested and f ound to com ply with the limits f or a Class A digit al device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio f requency energy and, if
not installed and used in accordance with the instruction manual, may cause harmful
interference to radio comm unications. Oper ation of this equipment in a residential ar ea is lik ely
to cause harmful interf erence in which case the user will be required t o correct the interf erence
at his own expense.

Canadian Department of Communications compliance st at em ent:

This equipment does not exceed Class A limits per radio noise emissions for digital apparatus
set in the Radio Interference Regulation of the Canadian Department of Communications.
Operation in a residential area may cause unacceptable interf erence to r adio and TV r eception,
requiring the owner or operator to take whatever steps are necessary to correct the
interference.

Avis de conformite aux normes du ministere des Communications du Canada:

Cet equipment ne depasse pas les limites de Classe A D'emission de bruits radioelectriques
pour les appareils numeriques telles que perscrites par le Reglement sur le brouillage
radioelectrique etabli par le minister e des Communications du Canada. L'exploitation faite en
milieu residentiel peut entrainer le brouillag e des receptions radio et t elevision, ce qui olbigerait
le proprietaire ou l'operateur a prendre les dispositions necessaires pour en eliminer les
causes.

2 Unpacking

2.1 UNPACKING

The packaging is designed for t ypical shipping and handling. Upon receipt of shipm ent, check
for signs of damag e before opening and report all damag e to the carrier. All shipments made
from DTS are the customer's responsibility once they leave our premises.

Before installation it is sugg ested that a complete inventory be taken t o minimize problems or
questions during installation. Addit ionally, save all packing mat erial until installat ion is com plete
in the unlikely event that a component(s) req uires return to the factory. Use the packing slip
that came with your unit to verify received inventory.

The following is a sample packing l ist for a single system.

Typical DTS Pro Audio Equipment Package consists of :

• CAE-4 Professional Encoder

• CAD-4 Decoder

• E175-DVD Timecode Controller

• E175-DVD (1/4” Jack) to Encoder ( XLR) Cable assembly

• E175-DVD power adapter

• DTS Software suite including the DTS Recor d Panal and bit str eam tools sof t ware on

Check time code trigger by setting up E175-01 DVD per section 6. Place CAD-4 into TC t rig
position to start encoding on user selected st ar t time.

3.2 ELECTRICAL SPECIFICATIONS

See spec sheets for summary specificat ions.

3.3 FRONT PANEL CONTROLS AND INDICATORS

The four pushbuttons from the left have LED indicators to show their status. Pressing the
button after reset chang es the state of the control. The only w ay to set the control back to its

default state is to press reset again. Always press the reset switch af ter changing a front
panel switch or int r oduci ng new content type (44.1K to 48K) at the AES/EBU input.

CD Mode ENCODER SPECIAL NOTE

Revision 2.2 Page 5

1234kbps is the only active mode for CD. The active front panel switches in CD mode are TC
TRIG or TC BYPASS and LFE ON or LFE OFF. In CD Mode, even thoug h the other switches
show lighted LEDs when switched to other positions, they are ignored by the encoder
processor.

In DVD mode, ALL front panel switches are fully activated.

3.3.2 Surround Switch 0dB/-3dB

In the 0dB position the LS/RS surround channels are not attenuated, which is the typical setting
for consumer encoding. T he - 3dB position setting attenuates the surround channels by 3 dB, to
accommodate the diff er ences in t heatrical consumer monitoring levels used while mixing.

3.3.3 TC Trig/TC bypass

In the TC TRIG State, the encoder will start encoding when the E175DVD start time is passed.
The Encoder will embed time code (DVD Mode) into the DTS output bit stream per appendix A.
The E175DVD is enabling encoding when incoming time code is between the user enter ed start
and end times. The green encoding indicat or on t he

E175DVD will be on when valid time code is output. Note: The “End” time must be greater than
the “Start” time. If the end time is not known, it should be enter ed with a larg e number (up to 24
hours). Refer to section 6 for operation of the E175DVD. Verify the star t and end times are
entered on the E175DVD screen. The TC St atus LED will blink at a 15Hz (f ast) rate before the
Encoder trigger point indicat ing that it is receiving t ime code and then blink at a 5Hz(slow) rate
after passing the tr igger point. The TC LED will be of f with no time code present.

The TC BYPASS switched mode does not require a time code gener ator input. The Encoder
will not embed time code. Once locked to valid AES/EBU dig ital inputs, the Encoder will start
encoding within a few seconds of turning the m ains power on. The Encoder, the T C LED, and
READY LED indicators will remain solid green.

3.3.4 Lfe On/Lfe Off

This switch controls the encoding of the LFE ( subwoofer) channel. W ith the switch in the ON
position, the encoder will brickwall lowpass the LFE input of the 120Hz and encode t he filtered
audio into a discrete LFE channel in the bit stream with the switch in the OUT position, audio in
the LFE input channel is ignored.

3.3.5 1509k/754k

1509kbps/754kbps are bit rate options for DVD encoding.
The bitrate for CD encoding is fixed at 1234 kbps.

3.3.7 DVD Status Indicator

This light indicates digital inputs at 48k samples/seconds. When the DVD led is “ON”, the
encoder will automatically select a bit stream.
