There are three different amplifiers that are used with the
different systems.
 | The A-903MK2 Amp is ideal for music room applications
to accommodate multiple inputs into the amplifier. |
 | The BG-115 Amp is used with the H-3 Speaker. |
 | The A-901A Amp is used with the F-121C Speaker because the
E-02R Module (the customized F-121C Speaker Equalization Module)
plugs into the A-901A and not the BG-115 Amp. |
