PRIMARY DIFFERENCES BETWEEN SV-3800 AND SV-3700 PRO-DAT.
1. Better Sound via oversampled SigmaDelta analog-to-digital converters , for improved 16-bit precision during recording, and optimized D-to-A converters with 20-bit playback resolution.
2. No more DIP switches!--All System Settings, including digital I/O connections, SCMS status, etc., are set via software, and stored in internal RAM during power down.
3. Flexible Connections and Status Display, with front-panel control of analog output levels, plus cross-assignment of consumer- and professional-format digital signals to rear-panel connections.
4. More I/O's __ Optical Consumer-Format Digital I/O's, in addition to coaxial/RCA connections.
5. New Single-Play Feature allows SV-3800 to play the program until the next Start ID, then stop until the PLAY key is pressed again.
6. Accurate Adjustment of Auto-PNO Threshold Levels between -60 and -20 dB, in 20dB steps.
7. Incorporates Independent Left and Right Input Level Controls.
8. Optional Parallel Remote Control offers multiple command modes via combinations of switch closures, or connection to external computer system, including "Go-to-PNO, and related search functions.

PRIMARY DIFFERENCES BETWEEN SV 3800 AND SV4100 PRO-DAT
1. Instant-Start Mode: The SV-4100 features a Ram-based Instant-Start Mode, which loads audio into a memory buffet. A selected Cue Point can be relocated forwards/backwards, use the Shuttle Wheel, or Skip/Setting, (Each press of Skip-FWD/Back equals +/- DAT Frame.) Press Pause once to audition Cue Point. Press Play to perform Instant Start and continue playing until Stop/Pause is selected.
2. Cue Points can be stored in four Memory Locations, hold and press down Locate 1, Locate 2, Locate 3 or Locate 4 buttons for at least 2 seconds.
(H:M:S:F location is stored in non-volatile RAM when unit is powered down.)
3. Absolute-Time Search Mode or " Go-to-A-Time" in H:M:S:F can be entered using the front-panel buttons, or an external computer via the parallel remote interface.
4. External Synchronization Mode enables the SV-4100's master CPU clock to be locked to External Video (25Hz PAL, plus 29.97 Hz and 30.0 Hz NTSC/film), Word Clock, or the digital Input. External sync is available in both record/playback modes. ("Cross-referencing" the External Video Sync and front-panel selection results in corresponding 0.1% mismatch from the selected 32, 44.1, or 48kHz sampling rates, for 44.056, 44.144, 47.952 and 48.048 kHz pull-up/downs for telecine and mixed-rate film/video applications).
5. Automated Assemble and Insert Edit capabilities, with instant start, using two SV-4100s interconnected together via parallel interface ports.

SELECTING SV-3800 INTERNAL STATUS DISPLAY MODE

Simultaneously press and hold down the Pause, Counter Mode and Counter Reset buttons. The 10 Display functions are identified by a single-digit number (0 thru 9) shown within the PNO display; Counter Display is current setting. Pressing Mode toggles next function; Reset cancels function.
Values can be changed in sequence by toggling SKIP-FWD button or, for output levels, using SHUTTLE WHEEL, Skip and REW/REV buttons.
0. Digital Output Format:*
"IEC-C" IEC 958 Type II Coaxial connector.
" IEC-C" IEC 958 Type II Optical connector
"AES" AES/EBU/IEC 958 Type I XLR connector.
1. Digital I/O Connector:*
"II AA" IEC 958 Type II-format to coaxial/optical output.
AES/EBU format to XLR output.
"II AI" IEC 958 Type II-format to coaxial/optical output.
IEC 958 Type II format to XLR-type output.
"IA AA" AES/EBU-format to coaxial/optical output.
AES/EBU format to XLR output.
"IA AI" AES/EBU format to coaxial/optical output.
IEC 958 Type II("consumer") to XLR-type output.
2. Error Rates, for Combined(A+B) Head Error Rate (maximum 9984); A-Head Error Rate(max. 4992); and B-Head Error Rate (max.4992).
3. Single-Play Mode causes SV-3800 to automatically drop into PAUSE mode when Skip-ID or next PNO is detected.
"SP--" single Play Mode set to off.
"SP 00" Single-Play Mode set to on.
4. Blank-Skip Mode causes SV-3800 to automatically SKIP-FWD to next PNO when it encounters blank section lasting more than 2 seconds during PROGRAM PLAYBACK.*
"PS--" Program Playback Blank Skip Mode set to off.
"PS00" Program Playback Blank Skip Mode set to on.
5. SCMS ID6 Setting during Record Mode, plus current SCMS status of tape:*
"00 P XY" SCMS ID6= "00" for record(copy-free); Tape Status - "XY".
"11 P XY" SCMS ID6 = "11" for record (copy restricted); Tape = "XY".
"10 P XY" SCMS ID6 = "10" for record (copy-prohibited); Tape - "XY"
6. Output Level Adjustment for analog port, between+4 dBU and -10 dBU. *Use the SKIP buttons or SHUTTLE WHEEL to increase/decrease level in 1dB steps, from -6 thru +4 dBU; REW and REV button step down/up to -10 dBU setting.
7. Head Cylinder Use, showing in Counter Display the number of hours of head revolution since manufacture.
8. Various Error codes and Operating Modes, plus Software Release(see page 33 of User Manual for a complete explanation of codes).
9. Peak Level Display, for accuracy setting replay/record levels. For levels setting between -16.8 and -19.3 dBU, the exact record/output level is displayed within the Counter Display(decimal point is represented by "-" sign). Use SKIP button to toggle between left and right channel settings.
* These parameters are stored within the SV-3800's non-volatile RAM. Values for most system settings can be re-initialization by pressing the following buttons: Pause, Counter Mode and Counter Reset; release only Pause, and then press Stop. "00000" is shown in the Counter Display to confirm re-initialization.(See page 34 of User Manual for full list of default settings.)
