Open Box TASCAM DA-3000 Master Recorder/ADDA Converter Level 1

The DA-3000 is perfectly designed for stereo PCM/DSD recordings at high sampling frequencies suitable for archival masters. This magnificent unit is capable of recording analog and digital signals up to 192kHz PCM or 5.6MHz DSD. The unit records to both SDHC cards and UDMA supported CF cards.

The variety of inputs and outputs enable connection with all types of studio equipment, including audio interfaces and mic preamps. The analog inputs and outputs include both XLR and RCA jacks. The digital connections include S/PDIF RCA coaxial and XLR jacks to support AES/EBU. The BNC SDIF-3 inputs and outputs support DSD digital connections.

With the goal of making a high-quality audio recorder and ADDA converter easy to use, TASCAM designed the front panel with all of the necessary external controls and included long, brightly lit meters and display. The 128x64 OEL display allows you to check necessary information quickly, and the 24-dot level meters allows you to confidently monitor levels at all times.

You can synchronize the operation of multiple DA-3000 units by interconnecting their digital inputs and outputs. Files that have been recorded in sync will have sample-level synchronization as well. In addition to stereo DSD recording of Jazz and classical music, this also makes simple DSD multitrack recording of bands possible.

Use of a dual mono structure for the output circuit eliminates interference between the left and right channels and achieves high audio quality by maximizing the performance of the components. Two high-quality mono circuits are built into the unit. The left/right channels each use one highly-acclaimed BurrBrown PCM1795 D/A converter chip.

The TASCAM DA-45HR, which is still used in many studios, uses a dual mono structure with NE5532 ope amps and BurrBrown D/A converters. By using an equivalent output circuit structure including DA converters of even higher quality that support DSD, the DA-3000 provides a portable high-quality monitoring system.

The internal circuit uses a fully-balanced structure that is completely resistant to noise from the inputs and outputs. This has a great effect on the output and input stage impacting the recorded audio. The input audio is digitalized by the BurrBrown PCM4202 ADC after it passes through the analog input circuit.

Operational amplifiers have a great impact on audio quality, so TASCAM carefully selected the NJM2114 and NE5532. In addition, they selected low-impedance capacitors featuring low resistance, low noise and high precision to emphasize audio quality.

In order to assure high-quality audio input and output, a stable power supply is indispensable. The EI core transformer incorporated into this unit has separate coils - one for the digital circuits and control panels and one for the analog circuits - making it possible to capture even higher-quality signals by suppressing noise. In addition, for the clock generator, we have used a temperature-compensated crystal oscillator (TCXO) that boasts 1-ppm precision.

Cooling fans inside equipment generate noise and can cause loss of accuracy when monitoring at low volume levels. With the DA-3000, TASCAM has achieved high performance in a fanless design, allowing you to maintain a comfortable monitoring environment that is free of fan noise.
