The Tascam UH-7000 is a pro-level USB interface for Mac and Windows that can also be used as a standalone mic preamp. It features built-in DSP mixer effects, supports 24-bit/192kHz USB transmission and AD/DA conversion, and is housed in a rugged metal casing for durability.

The UH-7000 is equipped with two HDIA (High Definition Instrumentation Architecture) microphone preamps that are designed to perform at −128dBu EIN, a 117dB signal-to-noise ratio and distortion ratio of 0.0009% or less. The Burr-Brown PCM4220 AD and PCM1795 DA converters allow for high-quality conversion, ensuring optimal sound reproduction for recording and monitoring.

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.

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.
