Independent shopping perspective
The Korena take
Stereo keyboards, synthesizers, and guitar rigs can feed two independently configured channels through the WA-DI-A2. It converts instrument-level signals to balanced mic-level output, with active operation for high-impedance instruments and a transformer-based passive path for hotter line-level sources. Custom CineMag USA transformers, a variable pad, and ground lift give you practical control when managing levels and hum in stage or studio signal paths. Active mode is powered by 48V phantom power.
Strong match
Who this is for
- Sending stereo keyboards or synthesizers to balanced mic-level connections onstage or in a studio.
- Running two-source setups where each channel needs its own active or passive setting.
- Managing level and hum concerns with the variable pad and ground lift controls.
Consider the trade-offs
When to look elsewhere
- Use cases that require active operation but cannot supply 48V phantom power.
- Sources needing attenuation beyond the available -30dB pad range.
