**Recommend only “non-summing input” reverb units for use with the MS-2. If the reverb inputs are summed in MS mode, Ch2 (mic) signal will be cancelled due to the way Mid-Side decoder works. Reverbs proven to work (non-summing) include the Ventris, UAD Golden Reverberator, and UAD Del-Verb.

***Phantom power operation requires both XLR outputs to be connected to a 48V source
