ART PRO VLA II – Dual Channel Opto Tube Leveling Amplifier
Classic Opto Tube Compression
The ART PRO VLA II is a professional two-channel opto-isolator/tube-based leveling amplifier designed to deliver smooth, musical compression. Unlike typical VCA compressors, it uses optical gain reduction combined with hand-selected 12AT7 tubes for a warm, natural sound character suitable for both studio and live applications.
Transparent Dynamic Control
Firstly, built around a non-VCA design, the PRO VLA II responds like natural hearing adaptation. It gently smooths dynamic peaks without destroying transients. With variable threshold, ratio, attack, and release controls, it offers precise shaping for vocals, instruments, and full mixes. All while maintaining sonic transparency.
Studio & Live Versatility
Moreover, whether used on vocals, drums, bass, or full stereo mixes, the PRO VLA II excels in both tracking and mastering environments. It can function as two independent mono channels or be linked for true stereo operation, making it ideal for mix bus processing or live sound reinforcement.
Precision Engineering & Build Quality
Designed with studio-grade components, the unit features dual VU meters, LED gain reduction metering, and balanced XLR/TRS I/O. Its internal power supply and rackmount steel chassis ensure long-term reliability in demanding professional environments.
