What is the power output of an amplifier rated as 2 x 100W when used with 2 speakers that require 160W (4 ohms) each?

There is a bit of misunderstanding here. The amplifier specification is a maximum power output - ie 2 x 100 W or less. The loudspeaker specification is a maximum allowed power input 160W or less -- ...

Furman power conditioner - can I use with a power bar to expand my outputs?

You should be fine plugging your power bar into the furman (i do the same thing) as long as you don't pull too much current. The pl-8c has a 15amp 'breaker' on it, so don't exceed that. I don't ...

When to use a power conditioner (e.g. Panamax M5400-PM) vs a pure sine wave UPS (e.g. CyberPower CP1500PFCLCD)

It seems unlikely that you need EITHER of those gadgets, but if you MUST choose one of them, the CyberPower gadget seems like more value for the $$$. The Panamix gadget seems like a vastly over-...

I am not getting any sound out of my PA system. Did I connect something incorrectly?

Start by checking the row of LED-s on the Numark. They show the output level from the Numark. If they are not blinking, the Numark does not send any signal. If not, where is your signal supposed to ...

Can power be supplied to a lavalier via the connector?

This isn't going to be possible. The power-adapter unit that sits between the connector and the mic is where the power comes from. It is not going to be possible to bypass this. Bear in mind that the ...

Splitting a condenser mic and using phantom power

Split it after the phantom power box. This way you have only one phantom source. If you had 2, any difference between them in voltage would create current from one source to the other. I suspect ...

Woofer size and power required to drive accurately 1 meter away microphone for frequencies 50-250 Hz

This question as it stands is not quite answerable. You could use a 5" or a 12" and both could be accurate in that frequency range. Size just allows for more movement of air. And they could be ...
