AER "Head One" Electric Bass Amplifier Head (275 Watt)

Integrated Amplifier For Electric Bass

Recommended Retail Price


With all the experience in acoustics, dynamic control and sound design AER reaches out into the field of professional electric bass amplification systems and introduces the AER Bottom Line Head One.

The concept: a small, light-weight two channel class d integrated amplifier head that covers the range from Anglo-saxon ‘punch’ to european ‘hifi’ orientated sounds. Head one can be used in three operational modes: 2-channel full range mode, 2-way active mode and bridge-mode in combination with Cab One, Cab Two or Cab Three.

It is equipped with ‘tube emulation’ for ‘drive’ sounds, two independent EQs, ‘colour-switch’ and ‘tone leverage’. Class d amps are getting more popular as besides efficiency they can be made so surprisingly small and light. Besides these benefits they inherit a lot of problems (noise, distortion, cut-off) especially if they are used in ‘limit mode’. Their overall performance is extremely depending on the design and the smart use of controls and protections to guarantee proper functionality. We have done a lot to make that happen!
