I was wondering anyone was familiar with the BBE Bmax preamp. What I need to know is - What is the output line voltage? I'll be running it through a QSC PLX-2402 at 4 ohms. The input sensitivity is 1.3 volts for this amp at 4 ohms. I've emailed BBE and they've given me no response - and it doesn't say on their website. Thanks!
