Does anyone know the effect send, preamp out and line out levels? -10db, 0db, +4 ? I'm having a bit of a problem connecting balanced line processors and the sends appear to be real low. Will it mess things up to try the balanced line out and returning in the effect return? I guess other alternatives would be to put a Sansamp Bass DI after the send to bring it to 0 db balanced or get something like a Radial J+4 to increase it to a balanced +4 signal. Any help would be appreciated.
