The EBS MicroBass 3 is a 2-channel preamp, built exclusively w/ premium components. It is engineered by EBS in Sweden w/ technologies from the famous HD360 and Fafner II amplifier designs. The preamp operates at a signal level equal to a professional mixing console (+/- 15V) which gives you plenty of headroom. The high signal level makes it suitable to use as a preamp in combination w/ any type of power amp.
Run the Clean and Drive channels in series or parallel. Use the dual balanced XLR-outputs to tap the signal post and pre EQ at the same time. If you run the Effects loop in stereo mode, the balanced outputs become a Left and Right output instead. w/ 10 Mohms input impedance, it handles any type of bass "¢Ã¢ š¬ passive, active or w/ piezo pickups.
The built-in tuner makes it easy to tune between songs without the need of an external device. The MicroBass 3 also carries an onboard compressor, similar to the one found on several EBS amplifiers, and several more features.
