Q: 8. Does this amp provide phantom power at 48V? I don't see it referenced in the manual.

A: The Toa Electronics BG-235 Amplifier & Mixer does not provide 48v phantom power.

Q: 9. TOA SR-HS3 recommended amplifier?

A: The Toa Electronics SR-H3S Slim Line Array Speaker - Long & Curved Version uses 360W RMS power at 8 ohms impedance. A compatible amplifier would first need to consider how many speakers need to be connected. In a scenario where one speaker is connected to each amplifier channel, a general rule of thumb is to provide around 20% more power than the speaker's RMS rating from the amplifier channel. In this scenario, an amplifier providing around 450W at 8 ohms from each output channel would be ideal.

Q: 10. The megaphone gives Feedback when in doors is there any way to stop it?
