Description
Focusrite ISA One Analog Single Channel Mic-Preamp
The Focusrite ISA One Analog Single Channel Mic-Preamp represents a pinnacle of audio engineering, delivering outstanding sound quality that draws from a rich legacy in professional music production. With its durable and portable design, the ISA One features the renowned ISA transformer-based preamplifier, celebrated across the audio industry for its exceptional performance. This product encapsulates the vintage microphone preamplifier topology of the original ISA110 module from Focusrite's Forté console, making high-end sound accessible to musicians and engineers at an approachable price point.
Versatility is a hallmark of the ISA One, thanks to its independent D.I. (Direct Input) channel, which adds significant functionality. It includes dedicated gain control, an active or passive impedance switch, and separate XLR and TRS outputs. This allows users to seamlessly blend a D.I. guitar signal with a mic'd guitar cabinet or handle vocal performances with ease, making it a favorite among versatile performers and recording engineers. The variable impedance circuit ensures precise matching with microphones, significantly enhancing recording quality.
The ISA One also boasts comprehensive metering and processing capabilities for optimal performance. The unit features independent input metering with a classic moving coil VU meter and dual six-LED peak meters, enabling pre- or post-insert metering for transparent audio signaling. User-friendly controls for phantom power, phase reverse, and a 75Hz high-pass filter are easily accessible from the angled front panel, providing an intuitive and efficient user experience. For those looking to push their recording capabilities further, an optional state-of-the-art A-D converter is available. Additionally, a dedicated headphone output with volume control allows for personalized monitoring through two TRS jack inputs, perfect for both studio sessions and live performances.
