The VC-8 is an adat/analog converter which allows connections to be made with adat optical exclusive digital multirecorder such as the VR-800 and various analog mixers. In order to accomplish high quality collaboration with analog mixers, the professional 20 bit type are employed for AD/DA. Also, to build a most effective system matched with the number of analog mixer output BUSes (2 BUS OUT, 4 BUS OUT, 8 BUS OUT) the INPUT MODE switch makes it unnecessary to reconnect the cables at record/playback. Furthermore, the VC-8 can be used as a S/P DIF/analog converter, and by connecting to the sound card contained in various computers with digital input/output, it will give a clean record/playback environment free of internal noise generated in the computer. Before operating VC-8, it is recommended to thoroughly read this manual to insure long life of this equipment. Precautions (please read before use) Power supply * When unplugging the AC adaptor from the outlet, be sure to grasp the adaptor. Attempting to unplug it by pulling on the AC cable may damage the wiring. * It is dangerous to use any power cable that is cut or frayed. If the power cable is damaged, immediately stop using it, and have it repaired. * Do not plug in or unplug the AC adaptor with wet hands. Doing so may result in dangerous electric shock. * Do not open the unit or touch any parts inside. Doing so may result in a dangerous electric shock, and could damage the unit. * Do not let water or other liquids, flammable materials, or metal objects such as pins get inside the unit. These things may cause electrical shock or short circuit the VC-8, and damage it. If the VC-8 should become wet, unplug the AC adaptor from the AC outlet, and contact your authorized service station. Outstanding Features * A digital multiple system can be setup by using the adat optical and analog in/out converter of the VC-8 together with various analog and digital mixers provided with adat optical such as the VR800. * Due to employ of the professional 20 bit AD/DA converter, it is possible in conjunctive operation with the analog mixer without degrading the high quality sound of digital recordings. * As the INPUT MODE is switchable, it is possible to construct a system to match the number of BUSSes in the analog mixer. * Additionally, as S/P DIF can be converted to the analog inputs/outputs and vice versa, it can be connected to the internal sound card of the computer provided with digital inputs/outputs. * Either the internal (44.1kHz) or OPTICAL/WORD (Phase adjusting range: 32~48kHz) can be selected and thus it can be widely adapted to digital equipment. Location * Avoid using the VC-8 in the following locations: * Locations of extreme low or high temperatures, or extreme changes in temperature. * Locations with excessive moisture or dust. * Locations where direct sunlight falls for an extended time, or near a stove or other source of heat. * Locations where electrical voltage varies. * Unstable locations or where there is heavy vibration. * Near strong magnetic fields (on top of a television or speaker). 3 Model VC-8 Owner's Manual Names and Functions ANALOG INPUT MODE switch This switch is used to select the channel to which the ADAT output should be assigned for the signal input to the ANALOG INPUT jack. This switch will be active only when the DIGITAL MODE switch is set to ADAT. Refer to pages 6 and 7 for details. POWER switch/POWER LED AC power to the VC-8 is switched ON/OFF (or "standby"). If the VC8 is not to used for a long period, the AC adaptor should be unplugged from the wall AC mains. WORD IN terminal switch This must be switched ON when the external WORD clock is input. ADAT/ANALOG CONVERTER OPTICAL CLOCK 75 ON OFF WORD OPTICAL INT(44.1k) LOCKED ANALOG INPUT MODE 1-2 1-4 1-8 DIGITAL MODE ADAT S/P DIF POWER STBY ON LOCKED LED This indicates status of the operating clock selected by the CLOCK selector switch. Refer to page 6 for details. CLOCK selector switch The VC-8 operating clock (INT, WORD or OPTICAL) is selected by this switch. Refer to page 6 for details. DIGITAL MODE selector switch The DIGITAL MODE IN/OUT formats (ADAT or S/P DIF) is selected by this switch. Refer to page 6 for details. DIGITAL INPUT/OUTPUT connectors ANALOG INPUT connectors (1-8) These are connected to BUS OUT (or GROUP OUT) of the analog mixer. Refer to pages 5 and 7 for details. There are connected to the VR800 digital multitrack recorder or to the DIGITAL IN/OUT connectors of a digital recorder provided only with digital in/ out connectors. 8 IN AD-12A ONLY 7 6 5 4 3 2 1 IN OUT 12V DC IN OUT 8 7 6 5 4 ANALOG 3 2 1 WORD IN DIGITAL OPTICAL DC IN jack (Center: Plus +) The AC adaptor (AD-12A) included with the VC-8 is connected here. Do not use an adaptor that is not soecified for the VC-8.) ANALOG OUTPUT connectors (1-8) These are connected to the TAPE INPUT jacks of the analog mixer. Refer to pages 5 and 7 for details. WORD IN connector (BNC) The external WORD clock signal is input here. Refer to page 5 for details. 4 Model VC-8 Owner's Manual Connecting Examples Example at operating it as the ADAT-ANALOG converter The following connecting schematic is an example of locating the VC-8 between an analog mixer with 8 TAPE IN - 8 BUS OUT (or GROUP OUT) and the VR800 (digital multitrack recorder). In this system, the 8 BUS output from the analog mixer is converted to adat digital signals and the signals of channels 1~8 can be recorded on tracks 1~8 of the VR800. DATA OUT WORD OUT SCSI OPTICAL DATA IN MIDI OUT IN AC IN POWER OUT DATA IN 8 IN 7 6 5 4 3 2 1 DATA OUT VC- 8 AD-12A ONLY 12V DC IN OUT 8 7 6 5 4 ANALOG 3 2 1 OPTICAL WORD IN WORD OUT VR800 BUSS OUT (GROUP OUT) 1~8 TAPE IN 1~8 Note: When connecting to a digital recorder with WORD OUT such as VR800, it always must be connected to WORD IN of the VC-8 and used by input of WORD clock. Analog Mixing Console Sound sources Note: When the digital inputs and outputs of the VC-8 and VR800 (or another digital recorder) are connected as shown in above connecting schematic, be sure to set one side as the clock master and the other as the clock slave. In other words, if the VC-8 had been set as the master, then VR800 (or another digital recorder) must be set as the slave, or if in the reverse situation whereas VC-8 had been set as the slave, then VR800 (or another digital recorder) must be set as the master. The most recommended setting at using the VC-8 is to establish the digital recorder as the master and the VC-8 as the slave as shown in table below. Recorder VC-8 CLOCK switch INT (44.1kHz) VR800 (or recorder): Slave VC-8: Slave VR800 (or recorder): Slave VC-8: Slave VR800: Asynchronous mode Other recorder: Internal mode VR800 (or recorder): Master VC-8: Master VR800: Synchronous mode Other recorder: External mode VR800 (or recorder): Slave VC-8: Slave The most recommended setting. Furthermore, if the WORD clock can be input, then WORD must be input. This setting is employed if the recorder (general DAT and MD) has an internal clock and thus cannot accept digital signals. Mutual exchanged of digital signals between the equipment is possible by this setting, but deterioration of sound quality is unavoidable. This setting cannot be used. A digital loop will be created in general type DAT and MD and thus will not operate correctly. CLOCK switch WORD or OPTICAL 5 Model VC-8 Owner's Manual Setup of the VR800 1. ...
