ART Dual RDB Line to Instrument Level Converter
Take your guitar and bass recordings to the next level with the ART Dual RDB. This smart dual-channel converter perfectly transforms line level signals to instrument level. Thus, making it ideal for sending DI tracks from your DAW to an amplifier for re-amping. Enjoy the flexibility to process two separate signals independently or blend one signal through two amplifiers.
Versatile Dual Channel Design
With two independent channels, the Dual RDB lets you route separate performances at once or split a single input to feed two amps simultaneously. The switchable Phase invert on the second output adds more control over signal polarity, helping create the perfect amp combination and richer tonal layers.
Professional-Grade Connections and Controls
Both channels feature dual 1/4″ TRS and XLR balanced line inputs with level controls on the front panel. You can precisely adjust the signal going to your amplifier without needing to tweak settings in your control room, matching the feel and response as if your guitar was plugged directly into the amp.
Passive and Powerful
The ART Dual RDB is a passive unit, requiring no external power or batteries. Its transformer-isolated outputs ensure clean, noise-free signals with a flat frequency response from 20 Hz to 20 kHz. This makes it a reliable and simple addition to any rig or studio setup.
