Do USB audio adapters supply bias voltage for lavalier condenser mics, and is TRS better than TRRS?

There are some USB audio adapters which provide 5 or 7 channel output on 3.5mm TRS sockets. Those tend to have microphone inputs with bias voltage on them, too. Only problem is that the quality is ...

sound reinforcement & power - Is it possible to utilize multiple power circuits?

First, NEVER tie hots together, for many reasons. Not the least of which is that they could easily be on different phases and result in an effective short. But you can split your load between two ...

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 -- ...

Correct Amplifier Rating for Klipsch RP-150M Speakers

It appears those speakers are rated at 75 watt continuous, 300 watt peak power, so it sounds like they would do fine as long as your amp is decent. It is worth pointing out that using a receiver as ...

Plug-in power microphone to PC

Electret condenser microphones will deliver output even without plugin power. Really, really bad, low-gain high-noise output. So you better make sure that the plugin power is actually switched on. ...

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-...

Do USB audio adapters supply bias voltage for lavalier condenser mics, and is TRS better than TRRS?

If you're getting an external USB audio interface, get one that supports phantom power [48v]. The Shure [& many other pro-level lav mics] comes with interchangeable adaptors for connectivity to ...

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 ...

Power supply for single Eurorack module

Important Caveat - never worked with modular before, but... Specs in the manual require +/- 12v only. No +5v requirement. Current requirements are +12v 150mA and -12v 45mA. This is well within the ...

How to power an outdoor DJ Set?

Generators are noisy (audible) and noisy (electrical). Best bet is some form of battery system that can output a sinusoidal wave (try to avoid square waves!). You could run a solar rig into 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 ...
