Like almost all amplifiers from LiREVO, the BASSORE series has a THD ratio below 0.1%, which clearly speaks for the good quality and efficiency of these amps. In the bass range there is the right practice amp in every size and in the end even stage-compatible solutions. Of course, all bassamps have parametric mid-range control, but from the B80 upwards even a dual EQ system that contains both the 3-band and an 8-band graphic EQ. An active and passive input channel on the front, as well as DI Out, Send / Return, Line-out and Tuner Out on the back. The DI Out can be switched pre / post and a ground lift is also considered. In addition to the extra fan unit, the 300 also includes a speaker out for a passive expansion speaker.
