Universal Audio 4-710D (4路話放連1176類壓限及數字輸出)

作為UA受歡迎的模擬產品系列的最新一員，4-710D結合了UA的經典設計方式和幾個現代技術革新– 這使它成為一個獨特的錄音棚設備，具有廣泛的應用範圍。4-710D的核心是四通道的聲音混合(tone-blending)“Twin-finity”話筒前置放大器，帶真正的1176型壓縮。基於獲獎無數的710 “Twin-Finity”前置放大器的設計– 它備受工程師們所讚譽，包括了Al Schmitt（Jackson Browne、Dr. John、Diana Krall的錄音師）和Matt Boudreau （the Samples, Sean O'Brien的錄音師） - 四個話筒前置放大器中的每一條通道都能夠在100%真空和100%固態之間都允許連續可變音調。

4-710D的其他顯著特性包括了：

• 每條話筒通道都有全新設計的1176型壓縮/軟限幅電路
• 8通道高質量24bit、192kHz 模/數轉換器
• 通過雙ADAT光纖口或者AES/EBU DB-25進行數字輸出
• 單片平衡式輸出級•平衡發送/返送插入

4-710d Four-Channel Tone-Blending Mic Preamp w/ Dynamics

Four Channels of Tone-Blending “Twin-Finity” Preamps and 1176-Style Compression with Built-In A/D Converters

The Universal Audio 4-710d is a boutique quality, four-channel microphone/line preamplifier with unique tube and solid-state tone blending capabilities — perfect for a wide range of microphone and instrument sources. This versatile multi-channel preamp offers selectable 1176-style compression circuitry on each channel, plus four additional line inputs feeding eight channels of pristine analog-to-digital conversion. Building upon UA’s classic analog design approach, combined with smart modern features, the 4-710d is the most flexible preamp in the UA lineup.

At the core of the 4-710d are four channels of tone-blending “Twin-Finity” mic preamps with true-bypass 1176-style compression, including specially tuned "fast" and "slow" settings. Each of the four mic preamp channels allows for continuously variable phase-aligned tone, between a 100% tube and 100% solid-state signal path. Send and return jacks are available for external processing or signal access.

• Four TEC Award-winning 710 Twin-Finity™ microphone/line preamps, each featuring:
• Phase-aligned tone-blending of tube and solid state circuits, creamy to crunchy
• Newly designed 1176-style compression circuit per preamp channel
• Backed by 1-Year limited warranty

The eight analog inputs are digitized via ultra high-quality 24-bit A/D converters at selectable sample rates up to 192 kHz. Digital output is available via dual ADAT “lightpipe” or AES/EBU DB-25 connectors, facilitating integration with most popular audio interfaces.
