An innovative hybrid bass amp
DB751 is an innovative hybrid bass amp-all tube preamp section composed of discrete MOSFET power amp section.
DB750 become previous model based on Preamplifiers and made improvements to the EQ control.
As a result, DB750 traditional tube drive is, of course, kid blends, possesses distinctive tone punchy.
2 Ω: 975 Watts, 4 Ω: 750 Watts of power are all musicians, realized the headroom.
(Both available LED indicator) adopt a self determining protection circuit and thermal dynamic overload protection circuit
