![]() With each step distortion is lower, mechanical and electromagnetic noise is lower, jitter is lower than the direct drive competition. This is easily noticed by more defined bass, clear highs, and a more musical mid-range. With each innovation the mechanical and electromagnetic noise are reduced which effects the quality of the music reproduction. The CEC TL0 3.0 uses the dual belt drive concept. The rubber belts are the only direct connection to the turntable and laser pickup drive. The turntable and the laser pickup plate is mounted with rubber suspension parts which isolate the motors mechanically from the turntable and the laser pickup. In the picture you can see the motors are mounted on a different plate from the turntable and the laser pickup. This minimizes mechanical noise and electrical interference. The dual belt drive design allows the motors driving the spindle and the laser pickup to be located away from the spindle and the laser pickup. The dual belt drive system minimizes the effects of mechanical vibration and electromagnetic noise from the motors. Music reproduction of compact disc reached a new summit with the CEC TL2N dual belt CD transport. The drive mechanism is isolated on a dual suspension system with high noise and vibration absorption. The spindle bearing centers the disc providing excellent vibration absorption characteristics. A precision rubber belt is used to connect the spindle and the motor. The spindle motor is isolated mechanically from the spindle. A stabilizer secures the CD disc to the turntable. You can fully enjoy your favorite CDs without worrying about changing belts.ĬEC uses a low torque motor which drives the spindle of the CD turntable. The belt can be replaced by the owner as needed, just like many record players. The CEC single belt drive mechanism employs a groundbreaking design that allows the condition of the disc drive rubber belt to be visually checked at any time. It does this by moving the motor away from the disc rotation axis and connecting the spindle and motor with a belt. The single belt drive CD mechanism reduces the effects of vibration and electromagnetic noise. CEC Single Belt Drive CD Turntable Mechanism The large motor makes it impossible to avoid signal distortion caused by vibration and electromagnetic noise generated by the motor. However, in order to obtain controlled and stable rotation, it is necessary to use a relatively large motor. The turntable is directly driven by the motor shaft. Ordinary CD players and transports employ a direct drive system in which a motor is placed directly below the disc turntable. This change in rotation speed of the CD turntable is controlled by the drive motor electronics. The rotation speed must be gradually reduced as the laser pickup moves to the outer edge of the CD to read the data at CLV. The music data on a CD is recorded at a Constant Linear Velocity (CLV). To this end CEC designs and builds their transport mechanisms in house. CEC designs their mechanisms and electronics to be top performing and CEC has brought many innovations to the market. CEC CD player and CD transports do one thing and one thing only, play “ Red Book” CDs without compromise at a price point. These all hurt the performance of CDs which when done properly is an excellent music source. Examples of these compromises are adding SACD capability, using zones speeds to control read rate, and interpolating the music data read. Many cd players and cd transports compromise there designs.
