Detaljer

Innimellom kommer det et produkt på markedet som dekker mange bruksområder. Ofte kan dette bety semmer kvalitet eller kompromisser. Med Tascam UH-7000 viser Tascam gammel storhet. Dette er et lydmessig meget flott produkt, til en fornuftig og markedsriktig pris. UH-7000 dekker mange oppgaver, men felles for alle er dens flotte lydkvalitet.

AD/DA konverter:          - som stand alone AD/DA konverter tilbyr den hele 123dB dynamikk-vindu både fra analog krets til digital konvertering, og tilbake. Dette er spesifikasjoner som er utrolig imponerende for en konverter i denne prisklassen. Her har Tascam lånt teknologi utviklet av moderselskapet Teac. De har en hi-end serie produkter i HiFi-kretser, som har fått ualminnelig mye skryt i en rekke tester. UH-7000 nyter godt av denne utviklingen.

USB 2.0 lydkort:               - som et lydkort fungerer den både til Mac og PC, og har støtte for de siste operativsystemene. Hentet fra sine små brødre, US-322 og US-366 får du en forsinkelsesfri lyttemikser med dedikterte effekter, slik at lyttingen blir meget god under opptak. Sistnevnte er meget viktig når man skal prestere. God og inspirerende lytting gjør selvsagt fremførelsen bedre. Her kan du ta opp i inntil 24 bit, 192kHz opptakskvalitet.

Mikrofon-preamp:         - Tascam har en historie det står respekt av. De har laget en rekke markedsledende studiomiksere gjennom årene, og forforsterkerne i mikserne deres var alltid regnet som ufargede og nøytrale. I UH-7000 sitter deres siste teknologiske utvikling, HDIA-forforsterkeren. I studiokretser er det to hovedretninger man kan velge når det gjelder selve mikrofonforsterkeren. Man velger enten en mikrofonforsterker som farger lyden i den retningen man ønsker med produksjonen. Her finnes en rekke muligheter, men noen av de mer legendariske er løsninger fra Neve og API.  Den motsatte retningen er å benytte ufargede forforsterkere som mest mulig slipper igjennom akkurat den lyden som mikrofonen fanger opp, uten å legge til eller trekke fra hverken frekvenser eller dynamikk. UH-7000 tilhører sistnevnte kategori, og fordelen med denne løsningen er at man senere i produksjonsprosessen har muligheter til å påføre ønsket lydfarging.

Hi-end lyd-streaming:  - UH-7000 er en glimrende løsning for alle lydentusiaster som ønsker å lytte på Hi-definition lyd direkte fra et mediebibliotek på datamaskinen. Man kan koble utgangen fra UH-7000 til hi-fi forsterkeren din, eller bruke den gode hodetelefonforsterkeren i UH-7000 og få en meget behagelig og god lydopplevelse. Inntil 192kHz hi-def lydfiler kan avspilles og konverteres til det analoge domenet. UH-7000 har selvsagt et fullt balansert analogt utgangssignal, med dedikert volumkontroll hendig plassert på frontpanelet.

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 built-in HDIA (High Definition Instrumentation Architecture) microphone preamps are newly designed with low noise and high audio quality. These impressive mic pres perform at −128dBu EIN, a 117dB signal-to-noise ratio and distortion ratio of 0.0009% or less.

The grand nature of the UH-7000's 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.

The units half-rack size makes it easy to install at a studio console or work desk. The thick aluminum panels on the front and sides of the full-metal body increase stability. Highly important but easily forgotten are the smooth-tension aluminum input level knobs for precise level adjustments.

The UH-7000 microphone preamp and audio interface enables composers, musicians and recording engineers to produce music in their private quarters at a level only reached in professional studios.



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.
Excellent input audio circuit specifications
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. 

Equivalent Input Noise (EIN): −128 dBu

Audio equipment generates a small amount of voltage even when all input/outputs are disconnected. This noise is calculated as equivalent input sound pressure, most commonly known as equivalent input noise (EIN). Signals at levels lower than this value are masked. -128 dBu represents the smallest signal level the UH-7000 can actually handle.

Signal-to-noise (S/N) ratio: 117 dB (mic to AD converter)
The signal-to-noise (S/N) ratio is a logarithmic value that expresses the amount of noise in comparison to the signal. As a value that indicates the performance of audio equipment, it is extremely important. As this value increases, the amount of noise decreases.

Total harmonic distortion (THD): 0.0009% or less (mic to AD converter)
With no distortion being the ideal, this value expresses the distortion (harmonic content) from the circuit. As this value decreases, the amount of distortion also decreases. Most other USB audio interfaces cannot reach THD levels this low.

Frequency Response: 20 Hz to 80 kHz, +0.005 dB/−0.16 dB (mic preamp at all sampling frequencies)
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".



High precision clock TCXO used to realize stable digital signal control
The clock generator can heavily influence digital signal quality; therefore the UH-7000 is built with a temperature-compensated crystal oscillator (TCXO). This oscillator has a higher precision than the crystal oscillators (XO) used in ordinary equipment. The timing clock uses a crystal oscillator that governs digital signals, but the frequency generated varies according to the temperature. In contrast, a TCXO includes a temperature compensation circuit that has exactly the opposite temperature characteristics of the crystal oscillator. These temperature characteristics guarantee stable clock generation. Compared to the norm, +/−100ppm precision (4.8 Hz at 48 kHz) produced from a standard crystal oscillator, the UH-7000 reaches +/−1ppm precision (0.048 Hz at 48 kHz).
Outstanding AD/DA converter performance with professional studio input/output solutions


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.
