Model 8335 (TC/SYNC card) Owner's Manual

Introduction

We wish to thank you for purchasing the Fostex Model 8335. The Model 8335 is an optional TC/SYNC card designed exclusively for the Model D-15 Digital Master Recorder. By installing this TC/SYNC card in the D-15, external time codes (LTC) can be converted to the IEC time code (set of PRO R-TIME and PRO binary) and recorded. Furthermore, A-TIME or IEC time codes recorded on the tape can be converted to time codes (LTC) and played back. Also, new functions such as the CHASE function (playback only) by external time code, phase modifying operation using WORD, VIDEO, and AES/EBU signals will be added to further complement the D-15 function.

In addition to functions added to the D-15 by installing the Model 8335, functions before installation and partial changes after installation are also explained in this manual. Before operation, we suggest that you read the D-15 manual together with this explanation.

1. Contents of Package

Accessory items packaged with the 8335 are as listed below. Please check contents with this list for any missing items. If anything is missing, please contact the Fostex Dealer or Distributor.

2. Installing the card in the D-15

Normally, Fostex Dealer or Distributor will install this card in the D-15. Therefore, please request the dealer or distributor of purchase to do the installation.

Major Functions

Recording external time code (LTC)

External time code (LTC) applied to the TIME CODE connector can be converted to the IEC time code (consisting of PRO R-TIME time code and PRO binary), which is the standard format for professional DAT time code recording, and then recorded.

In a D-15 installed with this card, 24 and 25 fps time codes can be automatically discriminated and recorded but 29.97 and 30 fps cannot be discriminated. Consequently, if recording 29.97 or 30 fps time codes are to be recorded, the D-15 must be setup matched with the time code which is recorded by the Model 8335 SETUP menu "411 -***."

Time code (LTC) can be recorded only during recording of audio signals (or no sound recording) and time code cannot be recorded individually. Also, if audio insert is carried out, time code of that section will be erased.

Refer to page [16] for time code recording and page [13] for SETUP menu "411 -***."

Conversion and output of A-TIME/IEC time code to LTC

When A-TIME or IEC time code is recorded on tape, it can be converted to LTC and output from the TIME CODE OUT connector. The frame rate and format of the time code (LTC) to be output can be randomly set by the SETUP mode.

Refer to page [18] for time code playback and page [11] ~ [12] for the SETUP mode.

Chase by external time code (LTC) is possible (At PLAYBACK only)

Time code chase against externally input time code is possible. In this case, the chase mode selecting and external sync signal selecting is set by the SETUP mode.

Refer to page [19] for chase synchronizing and page [15] for the SETUP mode.

Phase modifying operation by WORD IN, VIDEO IN, AES/EBU IN is also possible

Phase modifying operation by the external sync signal (WORD, VIDEO, AES/ EBU) is possible with the 8335 installed. External sync signal selecting can be set by the SETUP mode.

Refer to page [21] for details on phase modifying operation by an external sync signal and page [15] for the SETUP mode.

Time locate/memory edit by TC is possible

In addition to time locate/memory edit by A-TIME, time locate/memory edit by TC time will be possible.

Event start by REF TC is possible

Simultaneous with the external time code (REFERENCE TC) time coinciding with the memory [00] time, the D-15 will execute event start (playback mode). If the D-15 GPI switch is ON during this operation, then EVENT 0 will be output from GPI OUT.

TIME CODE

OUTIN

1.TIME CODE OUT connector (Connector: RCA pin jack - unbalanced)

Time code (LTC) converted from A-TIME on the tape or IEC time code is output here.

2.TIME CODE IN connector (Connector: RCA pin jack - unbalanced)

External time code (LTC) is input here. Because this connector is the switching type, if it is used in parallel with the balanced connector (XLR), priority is given to the unbalanced (RCA) connector.

3.TIME CODE OUT connector (Connector: XLR-3-32 type - balanced)

Time code (LTC) converted from A-TIME on the tape or IEC time code is output here.

4.TIME CODE IN connector (Connector: XLR-3-31 type - balanced)

External time code (LTC) is input here. If this is used in parallel with the unbalanced (RCA) connector, the RCA type will be given priority and thus this connector will not function.

5.VIDEO THRU connector (Connector: BNC type)

The external video sync signal is input here when synchronizing with the video sync signal.

6.VIDEO IN connector (Connector: BNC type)

The external video sync signal is input here when synchronizing with the video sync signal.

7.VIDEO IN terminating switch (75 Ω ON/OFF)

Termination of the VIDEO IN signal is switched ON or OFF but is normally switched ON. If a multiple connection is made via VIDEO THRU, then the last equipment only is switched ON and others switched OFF.

8. WORD OUT connector (Connector: BNC type)

Word sync signals are output here. When synchronizing with an external signal, word sync signals in sync with the external sync signal is output here.

9. WORD IN connector (Connector: BNC type)

The external word sync signal is input here when synchronizing with the word sync signal.

10. WORD IN terminating switch (75 Ω ON/OFF)

Termination of the WORD IN signal is switched ON or OFF but is normally switched ON.

Changes in D-15 functions and new SETUP menu items

There will be some changes in the displays and key functions by installing the 8335 in the D-15 Furthermore, SETUP mode menu items heretofore not effective will now be effective. The content of these changes and now effective functions only will be explained here. Therefore, in regards to other functions, please refer to the D-15 Owners Manual.

Content of changes

1. TC on tape will be shown in the FL display!

2. External time code (LTC) input will be displayed as the Reference (REF TC)!

Due to these changes in above 1. and 2., the display content will be different as a result of the D-15 DISP TIME key operation.

3. Input monitor of audio/time code is possible!

Input monitoring of audio and time code is possible by pressing the D-15 [INPUT MONITOR] key. However, if audio data is being read into the RAM under the INSTANT START mode, input monitoring will be switched OFF automatically. Refer to page [14] of the D-15 Owner's Manual on judging input monitor conditions by the INPUT MONITOR LED.

<NOTE>

If it is desired to confirm the time code time which is being input, change to the "REF TC" display by pressing the [DISP TIME] key so that the time code figure being input can be confirmed.
