Universal Audio 4-710d 4-Channel Tone-Blending Microphone Preamp

The Universal Audio 4-710d 4-Channel Tone-Blending Microphone Preamp is engineered to elevate your recordings with unparalleled flexibility and professional-grade sound quality. By fusing the timeless appeal of classic analog design with innovative modern features, the 4-710d stands apart as the most versatile preamp in Universal Audio's stellar lineup. This preamp marries vintage warmth with crisp, transparent digital output, making it an indispensable tool for studios looking to achieve professional results.

Featuring four top-tier mic/line preamps equipped with a unique tube/solid-state tone blending circuit, the 4-710d empowers you to fine-tune your sound effortlessly. Each channel offers both 100% tube and 100% solid-state signal pathways and allows for continuous blending between the two, providing an extensive range of textures from creamy smooth to audaciously crunchy. Additionally, every preamp channel includes true-bypass 1176-style compression, complete with quick “fast” and “slow” settings for immediate tweaking on the fly. This enables easy fattening of vocals, stabilizing bass guitars, and enriching synths and horns with sizzling texture.

On the connectivity front, the 4-710d shines with eight analog inputs and high-quality 24-bit A/D conversion. Selectable sample rates up to 192 kHz ensure pristine sound quality, and seamless integration with most interfaces is guaranteed through dual ADAT optical and AES/EBU DB-25 connectors. Furthermore, an ultra-low jitter clock subsystem and soft-limiters across all channels promise reliable, distortion-free audio capture. Whether you're expanding a home studio or upgrading professional facilities, the 4-710d is a multifaceted powerhouse that brings your microphone collection to life with unmatched preamp tones.
