Behringer UV1 Microphone Preamp

Behringer Ultravoice UV1 — Channel Strip with Midas Preamp and USB Interface

This unit combines a Midas-designed microphone preamplifier, a full vocal processing chain, and a 24-bit / 192 kHz USB audio interface in a 1U rack unit. With +48 V phantom power and 60 dB of clean gain, the Behringer Ultravoice UV1 captures vocals, instruments, and voice-over work while connecting directly to a Mac or PC without needing a separate audio interface.

Midas Preamp Heritage and Send/Return Insert Loop

A Midas-designed preamplifier circuit — the same heritage found in professional touring consoles — pairs with a send/return insert loop for adding external outboard gear. Digital and analog paths run simultaneously, so the processed signal feeds a DAW over USB while balanced outputs drive studio monitors or a live console at the same time.

Preamp Performance — Low Noise, High Gain, Flexible Inputs

The preamp section delivers clean, detailed amplification for both condenser and dynamic microphones, with switchable +48 V phantom power, an 80 Hz low-cut filter, and a wide gain range that adapts to any source.

• Microphone Gain: 0 to +60 dB — headroom for ribbon, dynamic, and low-output condenser mics
• Low-Cut Filter: -18 dB/octave at 80 Hz — removes rumble and proximity effect before processing
• The equivalent input noise is -126 dBu (20 Hz–20 kHz, 150 Ω), which is quiet enough for demanding broadcast and voice-over work.

Built-In Vocal Processing — Compressor, De-Esser, Enhancer, Gate

Beyond the preamp, this channel strip includes a full set of dynamics and tonal shaping tools designed specifically for vocal material, each with dedicated front-panel controls for real-time adjustment during a session.

• Compressor: Drive (-40 to +20 dB threshold) and Density (1–75 dB/sec release) — controls level and adds punch without artifacts
• De-Esser: Frequency 800 Hz–10 kHz, program-dependent threshold — tames harsh sibilance on vocal tracks
• Adjust the Expander/Gate with a Threshold Off to +15 dB and Ratio 1:1 to 10:1 to automatically mute room noise and breath between phrases.

USB Interface, I/O, and Zero-Latency Monitoring

The unit doubles as a 2-in / 2-out USB 2.0 audio interface, making it a viable hub for a compact home or mobile recording setup. A dedicated monitoring section blends the direct input with USB playback for latency-free tracking through headphones.

• USB Interface: USB 2.0 Type B, 24-bit / 44.1–192 kHz — connects directly to Mac or Windows 10 with no extra drivers on Mac
• Inputs: Combo XLR-1/4" TRS (front), 1/4" TRS line (rear), 1/4" TRS insert return — accepts mic, line, and external processor returns
• Choose from various outputs including Balanced XLR, balanced 1/4" TRS, 1/4" TRS insert send, and 1/4" TRS headphone to feed monitors, consoles, and outboard gear simultaneously.
