Each of the four channels includes a pair of RCAs and a stereo 3.5mm TRS inputs, while the mixer's output offers a pair of RCA and a stereo 3.5mm TRS connectors. Each channel features a level knob providing up to 30 dB of gain. The 3.5mm TRS output can also function as a headphone jack, providing enough power for most headphones. The MX44 Pro can be powered by an optional 9V battery or from the included 15 VDC power adapter.

Related Questions and Answers

Q: 1. do you need power for the mixer to work?

A: Yes it comes with a power supply.

Q: 2. 2 Qs: 1) Does this add any coloration to the signal; 2) will this work passively while it is powered down? One of the mics I'd be running through it is a Warm WA 47, which doesn't need the phantom power. I want to be sure that I can either go through the powered-up Rolls without it affecting the signal, or turn the Rolls off and just pass through it in passive mode. Sorry for the complicated and poorly phrased question!

A: The Rolls MX310 MorMics 3-Channel Mic Mixer/Combiner requires a power supply to function and is not passive. It does not specify any features that would color the signal specifically, however most electronic circuitry will typically influence the audio signal in some manner, typically minimally.

Q: 3. Is the "direct out" before or after any trim/gain adjustment? Looking to boost 8 mic signals to 8 line level. Will this do it?

A: The direct output on the Rolls RM82 8-Channel Mic/Line Mixer is taken immediately after the preamp stage, before any signal processing or adjustments.

Q: 4. What is the warranty? I have one a few years old and it's starting to have buzz issues.

A: Rolls rack mixers are covered by a limited one year warranty for parts and labor from the Manufacturer.

Q: 5. Is this supposed to work with 3.5mm headphones?

A: Yes, each channel has both 3.5mm stereo TRS and 1/4" stereo TRS headphone outputs.

Q: 6. If I input a 3.5mm mic will that get phantom power, and if so, how much, or is it just through the XLR connections?

A: Phantom power is provided through an XLR connection only. Mics that require power with a 3.5mm jack usually require plug in power which is approximately 2 - 5 volts. The MX310 is not able to provide this power.

Q: 7. How to connect to laptop for USB power?

A: I am not aware of an option to provide this with USB power. This comes with a power supply for use with wall plugin power only.

Q: 8. does this unit come with euroblock connectors included?

A: Yes it does. It comes with 4 - Balanced via Euroblock connectors, 2 - Mic / Stereo Inputs via Euroblock connectors and 2 - Stereo Inputs RCA Type via Euroblock connector, see manual for wiring configuration.

Q: 9. I have a roku, fire box, and a cable box rca audio to a reciever. I have what I think is the same. I have to get up and manually change sources. Will this do what I want automatically. Also there is sound comming out of these things most of the time, is that a problem?

A: Yes, it will combine all four sources into one output. I use it to combine multiple karaoke units and wireless microphones so it would be one source on receiver. It isn't powered so doesn't matter if it has audio sending to it all the time. If you have two sources going at the same time though, you will hear both. It does not automatically switch, it just combines. So this probably won't be what you want. You will have to change sources anyway to switch the video input between devices. I would get a new receiver that has an app for remote control.

Q: 10. hello - presumably this is compatible anywhere in the world?

A: I don't see why not, there are no active components inside.
