Lanzar Opti 2050, 2100 & 4100


above: circuit side (bottom)

2050 | 2100

below: control panel

Overvue:

  • Pretty much the top half of the board is power supply
  • EQ curcuits are on the main board next to their respective driver daughter board (each EQ uses two LM 833N). If you didn't need any EQ much (if not all) of this circutry could be bypassed or removed*
  • Driver board is all discreet transistors
  • the light green areas snap off yielding board sizes of: 2050 4.75"x7.5"/2100 4.75"x9.25"/4100 anyone

* i can imagine seeing boards with all the PS & EQ removed leaving mostly empty space
