- High Performance Power: Independent high-capacity toroidal core transformers are dedicated to the digital control section and the CD mechanism, ensuring stable and clean power supply.
- Integrator Friendly: Compatible with RS-232 for seamless integration into existing home audio systems.
- Vibration Control in Every Detail: The CD mechanism is mounted on a semi-floating sub-chassis, and power transformers are on a floating structure to reduce vibration transmission. Heat dissipation fins are designed with varying lengths to eliminate sympathetic vibrations.
3. Setup Guide
3.1. Unpacking and Placement
Carefully remove the VRDS-701T from its packaging. Place the unit on a stable, level surface away from direct sunlight, heat sources, and excessive moisture. Ensure adequate ventilation around the unit.
3.2. Connections
The VRDS-701T is a CD transport and requires connection to an external Digital-to-Analog Converter (DAC) or an amplifier with a built-in DAC. Use high-quality digital cables for optimal performance.
- Digital Audio Output: Connect the Coaxial (RCA) or Optical (TOSLINK) digital output from the VRDS-701T to the corresponding digital input on your DAC or amplifier.
- Clock Input (10MHz IN): For enhanced synchronization and audio precision, connect an external 10MHz master clock generator to the BNC clock input.
- RS-232C: Connect to a control system for integrated operation.
- 12V Trigger: Use for synchronized power on/off with compatible equipment.
- Power Connection: Connect the supplied AC power cord to the AC IN terminal on the rear panel and then to a suitable wall outlet.

5. Maintenance
To ensure the longevity and optimal performance of your TEAC VRDS-701T, follow these maintenance guidelines:
- Cleaning the Unit: Use a soft, dry, lint-free cloth to wipe the exterior of the unit. Do not use abrasive cleaners, waxes, benzene, alcohol, or other chemical solvents, as these can damage the finish.
- Disc Handling: Always handle CDs by their edges. Avoid touching the playing surface to prevent fingerprints and scratches. Store discs in their cases when not in use to protect them from dust and damage.
- Ventilation: Ensure that the ventilation openings on the top, sides, and rear of the unit are not blocked. Proper airflow is crucial to prevent overheating and maintain stable operation.
- Power Off: When the unit will not be used for an extended period, it is recommended to disconnect the power cord from the wall outlet.
6. Troubleshooting
If you encounter issues with your VRDS-701T, refer to the following common troubleshooting steps before contacting support:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power, unit does not turn on. | Power cord not securely connected; power outlet is faulty; unit is in standby mode. | Ensure the power cord is firmly plugged into both the unit and a working wall outlet. Press the power button on the front panel to switch from standby to ON. |
| No sound output from connected DAC/amplifier. | Digital audio cable not connected or loose; incorrect input selected on DAC/amplifier; DAC/amplifier is off or faulty. | Check that the Coaxial or Optical digital cable is securely connected between the VRDS-701T and your DAC/amplifier. Ensure the correct digital input is selected on your DAC/amplifier. Verify the DAC/amplifier is powered on and functioning correctly. |
| Disc not playing or unit displays "No Disc". | Disc is dirty, scratched, or damaged; disc inserted incorrectly; unsupported disc format. | Clean the disc with a soft, lint-free cloth, wiping from the center outwards. Ensure the disc is inserted correctly with the label side up. The VRDS-701T supports standard audio CDs. |
| Skipping, stuttering, or distorted audio during playback. | Disc is damaged or severely scratched; unit is subject to excessive vibration; internal issue. | Try playing a different, known-good CD. Ensure the unit is placed on a stable, level surface and is not exposed to external vibrations. If the problem persists with multiple discs, contact support. |
| Remote control not working. | Batteries are dead or inserted incorrectly; remote sensor is blocked; remote is out of range. | Replace the batteries with new ones, ensuring correct polarity. Remove any obstructions between the remote and the unit's front panel sensor. Ensure you are within the effective range of the remote control. |
If the problem persists after trying these solutions, please contact TEAC customer support or your authorized dealer for further assistance.
