Royer dBooster2 雙聲道麥克風訊號增益器/DI

Royer dBooster2 是一款雙聲道發燒級麥克風訊號增益器（mic lifter），具備原版 dBooster 的一切優點，並將其擴充為雙聲道，且兩個聲道皆可兼作電吉他與貝斯的超純淨 DI（直接注入盒）。兩聲道完全獨立，你可同時接入兩支麥克風、將兩聲道都作為 DI 使用，或混搭使用——一邊接麥克風、另一邊當 DI。

接上麥克風時，dBooster2 可在「將輸入訊號提升兩倍以上」與「提升四倍」之間切換，無論搭配何種麥克風與前級，都能維持無與倫比的動態餘裕且不損失增益。Mic 模式下，20dB 設定將輸入訊號提升四倍，為收錄較輕柔的樂器與歌手提供大量純淨增益；面對高音量樂器或大聲的歌手時，則可切換至 12dB 設定，避免前級或數位介面過載。使用 DI 輸入時，可選擇 0dB（unity）增益，或切換至 8dB 增益以獲得更高電平，同樣享有 dBooster 超純淨的高階電子線路。

The Royer dBooster2 is a dual-channel audiophile mic lifter — everything the original dBooster is, in two channels — and both channels double as super-clean DIs for electric guitars and bass. Both channels are fully independent, so you can plug in two mics at once, use both channels as DIs, or mix them up — one side for a mic and the other for DI. With microphones plugged in, the dBooster2 lets you switch between more than doubling the mic’s input signal and quadrupling it, maintaining unrivalled headroom with no loss of gain regardless of the mic and preamp being used. In mic mode, the 20dB setting quadruples the input signal for loads of clean boost when recording softer instruments and singers; for higher-volume instruments or loud singers, the 12dB setting keeps your preamp or digital interface from overloading. Using the DI inputs, you can select 0dB (unity) gain or switch to 8dB for more level, still enjoying dBooster’s ultra-clean high-end electronics. Its dual Class-A input stages deliver crystal-clean gain with virtually no noise or self-distortion, and its low-impedance output delivers audiophile performance in the studio and on live stages, driving long cable lengths and difficult loads like mic splitters and vintage-style preamps with no distortion, no loss of gain, and more headroom than any other mic lifter. It gives outstanding performance with Royer R-121s, R-10s, and stereo SF-12s — or any ribbon mic — and opens up dynamic mics like SM7bs and RE-20s in a way you have to hear to believe. It offers high input impedance, balanced low output impedance, rugged case construction, and wide frequency bandwidth, and protects ribbon mics from phantom power. Built in the USA.
