Most amplifiers have a “trim” or “gain” knob to control the input level. Why doesn’t the A1 amplifier have one?
Bose® engineers know that extra controls can equal setup time at the gig. The input stage of this amplifier is designed for the power stand. On the other hand, has an input impedance appropriate for most pro audio components such as mixing consoles. When you use the A1 with such pro audio components, use the output fader on an upstream mixing console to adjust the level of signal going to the A1 amplifier.
