Description:
The Studio 4 Pro OTG represents the most capable model in the STUDIO PRO OTG GEN II family, engineered for creators demanding the highest studio standards. Its balanced mic section features extended frequency flatness (10 Hz–22 kHz ±0.1 dB), wide dynamic range (~110.6 dB A-weighted), and very low distortion (<0.0011%), providing clean, accurate capture for vocals and instruments alike.High-headroom balanced line inputs handle up to +22.3 dBu with very low noise and distortion, while the high-impedance instrument input ensures faithful DI signals at up to +12.1 dBu. Analog outputs deliver the widest measured dynamic range in the family (~108.7 dB), preserving mix detail from DAW to monitors.
The headphone amplifier pushes up to 114 mW into 50 Ω, enabling precise reference listening. With full OTG/USB class-compliance and up to 192 kHz resolution, the Studio 4 Pro is built for multi-source tracking, full production sessions, and professional monitoring in both mobile and fixed rigs.
Product Benefits:
• Highest dynamic range & headroom in the lineup
• Ultra-clean analog path for critical tracking
• OTG & high-res USB connectivity
