The UH-7000 is a pro-level microphone preamp and audio interface, designed with a strong focus on low noise and high audio quality. Not only can this unit be used as a 4-in/4-out audio interface in a DAW production environment, but as a standalone microphone preamp and AD/DA converter. The sound is partially due to the careful attention spent on selecting parts. In addition to the Burr-Brown PCM4220 ADC, PCM1795 DAC converters and thin film metal resistors, installed is a powerful TCXO clock generator with +/−1ppm precision.

What Makes The TASCAM UH-7000 2-channel USB Audio Interface so Awesome?

• HDIA Mic Preamps Capture Detailed Nuances – The High Definition Instrumentation Architecture (HDIA) mic preamp maximizes high specifications that produce the lowest noise. Parts were selected through repeated listening tests in order to confirm high-performance in both numerical ratings and actual audio quality. The instrumentation amplifier method requires a large number of parts and labor; therefore it is rarely used in ordinary audio equipment. Designed with a circuit that is used not only for professional audio equipment but also in measurement devices that handle highly detailed signals, the UH-7000 is capable of capturing the finest expressive nuances for all musical performances.           
• Circuit Specifications and Clear Audio Response - The analog audio input circuit was designed to achieve low noise and high   audio quality throughout the entire signal. Key parts only made the cut after many intense listening tests. Everything from the film capacitors for improved noise performance to the thin film metal resistors and others. The frequency response used for audio equipment expresses the sound pressure frequency characteristics. Since this showcases how each frequency of the input audio (sound pressure amplitude) varies, it is often shown as a graph.
• When expressed numerically, the frequency range and amplitude variation values are used. The ideal value is a straight-line graph from the lowest frequency to the highest frequency. The closer the response is to being flat, the more accurately the characteristics of the source sound are maintained. People tend to focus on the frequency range, but the amplitude variation is very important. For example, "20 Hz–20 kHz, +/−1 dB" is closer to being flat than "20 Hz–20 kHz, +/−6 dB"
• Large Aluminum Input Level Knobs and 20-Segment LED Level Meters for Precise Recording –The UH-7000 is fronted with large aluminum input level knobs The smooth-tension knobs of the UH-7000 support extremely fine adjustments. The unit also includes independent 20-segment LED level meters. In combination with the large knobs, recording levels can be adjusted even more precisely. The UH-7000 starts up in mic pre only mode automatically when not connected to a computer. This unit is an ideal choice as a mic preamp for master recorders such as the DA-3000.
• Outstanding AD/DA Burr-Brown Converters – The internal circuitry is furnished with Burr-Brown's impeccably pure PCM4220 AD converter. This converter uses a high performance chip that was developed specifically for professional audio and boasts a dynamic range of 123 dB (−60dB input, A-weighted) in isolation. Audio signals digitized by the PCM4220 can be sent via USB to the computer or output from the XLR AES/EBU digital output jacks.
• For digital-to-analog conversion, the UH-7000 uses the equally impressive Burr-Brown PCM1795. The digital inputs and outputs support transmission in IEC60958-4 (AES/EBU) and IEC60958-3 (S/PDIF) formats.
• Powered Monitor Volume Control – The link line function allows the line output volume to be adjusted using the headphones volume knob. This allows users to connect the unit directly to powered speakers and adjust the monitoring volume without need for a mixer or other equipment.
