    Depth (main frame) 17 inches (431.8 mm) 1-4.2 Power Requirement. The VR320 is factory-configured for the line voltage of the country of installation. Fuse type is 2A, 250V, time-delay, 20 mm (Eventide P/N 316054). Same type is used for 115 Vac or 230 Vac.

  • Page 18: Preparation For Use And Installation

    Chapter 3 of the Operator’s Manual discusses the detailed configuration procedures for setting up your unit at your facility. It is assumed in this section that you have an audio input signal available to be connected to the VR320 Channel One input. 2-2.

    2-6. SYSTEM CONNECTION. Figure 2-1 shows the rear panel of the VR320. There can be up to six telephone or audio input connectors, depending upon the number of optional channel boards installed. Your primary job will be to connect the input channels to your signal sources. Additional tasks include providing power, audio output, and, if desired, PC remote control, and printer interface signals and connections.

    Model VR320 Audio Logging Recorder 2-8. INPUT OPTIONS. Up to three input boards may be installed in each VR320 mainframe (see Figure 2-2). This manual describes the three board styles available. 1) Voice-quality audio input board (8 channels). 2) FCC-registered telephone board (8 channels).
  • Page 36 Model VR320 Audio Logging Recorder For each of the eight channels on an input board, there are six signals available at the 50-position socket: two signals for differential audio input, one for audio output, one for squelch or record enable control, and two grounds. If there are three input boards installed, the top board contains channels 1-8, the middle board contains channels 9-16, and the bottom board contains channels 17-24.

    3-1. DESCRIPTION. Setup is a configuration procedure performed from the front panel of the VR320. At this point, we assume that the unit is connected to power and audio, and is powered up. If so, you will be looking at an LCD display with a legend indicating either Ready or Not Ready depending upon whether the drive is loaded.
  • Page 46 This may be very close to accurate, or completely incorrect if never set. The clock is powered by a lithium battery that allows it to keep time even if no power is applied to the VR320. If the battery is discharged, the date and time will be wrong.

  • Page 47: Section Ii. Global System Configuration

    As discussed elsewhere in this manual, the number of samples determine the media usage. This is a linear function. Doubling the sampling rate reduces the recording time by half. The audio quality of the VR320 is dependent on the sampling rate. Jan 26/99...

  • Page 49: Security

    A technical note: Normally one would expect sampling rate to change frequency response. The VR320 has a fixed frequency response of slightly over 3 kHz. This would normally imply a sampling rate of about 8kHz and, in an 8-bit system like this one, a 64K (8 times 8) bit per second sampling rate would be required.
  • Page 50 Lock ChangPaswd (Change password) – When the VR320 is shipped, it is initialized with an 8- digit password “00000000” (eight zeros). This will be the password unless you change it from this menu. When you press the F1 (the ChangPaswd soft key), the unit requests the original password, which you enter using the keypad.
  • Page 51 If you enter the password twice and both versions are identical, the VR320 will accept the new password and the old one will then be invalid. If you do not enter the correct “old” password or if you make any mistakes during this procedure, it will abort and leave the password unchanged.

    Model VR320 Audio Logging Recorder In the Do NOT mode, in order to record on a drive on which media has already been recorded, it is necessary to eject the old medium and insert another.

Note that the VR320 will not allow you to select a print interval that is shorter than the collection interval. Each printout comprises a heading and shows the interval covered by the printout.

  • Page 63: Time Track

    Time Track is a feature that can be enabled to assure that the media is “always running.” One of the main advantages to the VR320 is that no space on the media is used when there is nothing to record. In some applications, however, it is desirable to have a continuous time track to be able to prove that the media was running continuously and that no input was missed because it was temporarily stopped.

    Assuming you have a VR320 with two tape drives. Whenever you start recording on the Upper media drive, the VR320 creates a file on the hard disk. The file name will be something like UPRFILE.

    Descriptors (on the secondary menu) is a powerful and hence potentially “dangerous” option that will copy the channel descriptors from the media in the selected drive to the memory of the VR320. The “danger” lies in the fact that it is time consuming to enter descriptors manually and, once they have been changed, the only way to get the original ones back is to re-enter them, unless, of course, you have media with the original descriptors.

    Model VR320 Audio Logging Recorder In digital recording, as used on the VR320, the audio signal is measured at regular intervals and converted to numbers.

  • Page 112: Sampling Rate In The Vr320

    SAMPLING RATE IN THE VR320. In the VR320, the recording time of a tape depends on the “sampling rate” chosen via the front panel. We chose the term “sampling rate” because it is more obviously related to digital audio than “transcoding rate”, which is a more accurate term.

  • Page 114: Tape Usage

    Therefore, if only two channels are active, an 8-channel VR320 will use tape only one fourth as rapidly as an 8-channel analog recorder. This, along with the rotating head technology, digital signal processing, and the nature of the tape itself, is what allows us to record so many hours on such a small tape.

    Another benefit of the hard disk drive in the VR320 is that it prolongs the life of the tape drives. Here’s why: a DDS tape drive is either “streaming” (recording data on tape at a fixed rate of about 500KB per second) or it is stopped.

    It has a large, configurable display that shows a time display as setup by the user. The clock generates a time code for the VR320 which will keep the VR320 accurate with respect to UTC or local time indefinitely. Further information on this clock is available from Eventide. If you use this accessory clock, most of the information in Appendix A will be of little interest and can be disregarded.

  • Page 175: Clock Frequency Adjustment Procedure

    A-4. TIME CODE INPUT. The VR320 provides an input for a time code generator. By sending time data, the clock of the VR320 can be automatically updated and corrected so that it remains within two seconds of the generator at all times. The time code input overrides the internal clock, so that setting the clock (or clock frequency) as described in The VR320 maintenance manual is unnecessary.

  • Page 176: Configuration And Data Format

    Configuration of either channel B (RS232) or channel F (RS485) may be used. In order to receive time code data, the generator must create the data in the proper format, and the RS-232 parameters of the VR320 must match those of the generator, whose data is received on RS-232 channel B.

  • Page 177: Vr320 Clock Example

    It is normal for the VR320 internal time to differ from that of the time code generator by up to two seconds. It is also normal for the VR320 to require up to a minute before responding to time changes commanded by the generator.

  • Page 178: Status Printer Indication

    When the second sequence is received, the VR320 will synchronize with it. This format is generated by Eventide’s accessory clock, described at the beginning of this Appendix, and is also an available output format from the Spectracom NETCLOCK/2. Spectracom can be reached at (716) 381-4827.

  • Page 179: Appendix B 4Mm Tape Issues

    These cartridges are colloquially and redundantly known as DAT tapes (Digital Audio Tape tapes). It is important to understand the differences among the tapes usable in the VR320. In some applications it may not matter which brand or quality you use; in others it may be critical.

  • Page 180: The Tape Counter And Tape Capacity

    B-4. THE TAPE COUNTER AND TAPE CAPACITY. The VR320 recognizes and operates with 90, 120, 125 (DDS-3 equipped machines) meter DDS tapes. The tape counter is re-calibrated depending upon the length of the tape. Therefore, “tape full” will occur in the 9900-9999 range regardless of selected length. Tape changeover, in units so equipped and configured, usually occurs in the 9600-9900 range.

  • Page 181: Deliberate Erasure

    If you feel you must erase a tape for security reasons, you can use a standard audio DAT recorder to record over it. Alternatively, use the COPY function of a dual-drive VR320 to record non-critical data over the material to be erased. Jan 26/99...
