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 though 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. The -3dB position setting attenuates the surround channels by 3 dB, to
accommodate the differences in theatrical 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 bitstream per appendix A.
The E175DVD is enabling encoding when incoming time code is between the user entered start
and end times. The green encoding indicator on the
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 entered with a large number (up to 24
hours).
Refer to section 6
for operation of the E175DVD. Verify the start and end times are
entered on the E175DVD screen. The TC Status LED will blink at a 15Hz (fast) rate before the
Encoder trigger point indicating that it is receiving time code and then blink at a 5Hz(slow) rate
after passing the trigger point. The TC LED will be off with no time code present.
The
TC BYPASS
switched mode does not require a time code generator input. The Encoder
will not embed time code. Once locked to valid AES/EBU digital inputs, the Encoder will start
encoding within a few seconds of turning the mains power on. The Encoder, the TC 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. With the switch in the ON
position, the encoder will brickwall lowpass the LFE input of the 120Hz and encode the 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.
