Universal Audio Volt 4 Max: The Ultimate 12-In / 6-Out Desktop Studio Interface
Featuring professional 32-bit / 192 kHz conversion, two preamps with Tone Shaping and Max Processing, an extensive 12-in / 6-out I/O with optical ADAT expansion, Main/Alt speaker switching, and a built-in talkback microphone, the Volt 4 Max is the beating heart of any modern recording studio.
Why Choose the Universal Audio Volt 4 Max?
1. Tone Shaping & Max Processing (Over 18 Sound Combinations)
Instantly give your recordings the analog tone you want without latency or complicated software settings:
- 3 Tone Shaping Modes: On each channel, choose between Warmth (rich UA 610 tube sound), Focus (tight solid-state clarity), or Shine (open, airy British Class-A high-end).
- Max Processing Presets: Onboard analog dynamics processing with 6 custom compressor presets for vocals, guitar, and bass (such as Rap Vocal, Album Vocal, Electric Guitar, and Tight Bass), based on legendary 1176, LA-2A, and VCA hardware.
2. Superior 32-Bit / 192 kHz Audio Conversion
Thanks to a dynamic range of 119 dB on the inputs and 126 dB on the monitor outputs, you can capture every musical nuance with razor-sharp clarity. From subtle acoustic instruments to powerful vocal signals: your mixes remain transparent, detailed, and noise-free.
3. Extensive Connectivity: 12 In / 6 Out with ADAT Expansion
. Effortlessly connect all your studio equipment. In addition to the analog inputs, the Volt 4 Max features an optical ADAT/S/PDIF input. This allows you to easily expand the interface with up to 8 additional digital channels for recording drums, synthesizers, or an entire band.
4. Professional Monitoring: Speaker Switching & Talkback
- Main / Alt Speaker Switching: Switch between two different sets of studio monitors with the push of a button to check your mix on multiple systems.
- Built-in Talkback Microphone: Communicate directly from your control room with musicians in the recording room.
- Two Headphone Outputs: Equipped with a 6.3mm TRS and a 3.5mm stereo headphone jack (with a dedicated cue mix) for seamless collaboration.
5. Smart Display, Auto-Gain & Clip Protection
- Full-Color Smart Display: Provides immediate, clear visual feedback on levels, selected settings, and real-time gain reduction from the compressor.
- Auto-Gain: Let the Volt 4 Max automatically determine the ideal recording level in just a few seconds.
- Clip Protection: Prevent distorted recordings caused by unexpected loud peaks; the hardware automatically intervenes to prevent clipping.
