How to use MiPro MR-90, and wireless transmitters generally

[Ty Ford]

Hello John and welcome to the Cow Audio Forum.

A simple google search reveals this:

https://www.audiolines.com/product.php?productid=69527&cat=953&page=1

So 6b, is a range of frequencies.

MiPro is not considered pro level gear. I’m not familiar with it’s operation. Perhaps you can find more operating instructions on their web site.

Regards,

Ty Ford

I tried digging around Mipro’s website, as well as it’s parent company’s site, and wasn’t able to find any links for user/operating manuals.

I would recommend that OP contact the company directly for information – they should be able to send you a PDF via e-mail and also help you with any questions you have, basic or advanced.

Thanks for the suggestions Jordan and Ty. I haven’t had much luck getting any useful info out of MiPro’s web site. I sent them a couple emails asking for manuals, but haven’t heard back yet.

John,

I would HIGHLY recommend you read up on the basics of wireless microphones. You don’t have to know the theories and formulas behind RF transmission, interaction, etc. but you should know how to set up any wireless mic system – the basic rules don’t change. You need to know what type of antennas your unit uses, how to correctly set the frequencies so that intermodulation distortion doesn’t occur when using multiple mics, and how to correctly set your gain structure from the microphone all the way through to the end device, be it a camera or separate audio recorder.

Good luck and let us know if we can be of more assistance.

Hi John,
Just came across your post, not sure if you got it sorted, but if not hope the following helps.
I’ve got 3 of these systems and have had no problems with them at all. They are quieter than a lot of the top manufacturers lower end products, e.g. sennheiser G2. If you google the Sennheiser EK3041, you may notice some similarities! Mipro are the OEM manufacturer for Beyerdynamic radios, and I know people who regularly use 32 of the ACT rackmount systems for musicals, completely interference free.
The principle of the ACT system is that it can scan the frequency band it is operating on, and will then select an interference free frequency (you can also manually select a frequency by selecting a group, then a channel). Once the frequency is selected, press the ACT button on the receiver, whilst holding a powered up transmitter with the ACT window (looks a bit like an IR window, and has ACT printed near it) within 20cm of the receiver ACT button. This will set the transmitter to the same frequency as the receiver, and hey presto!!!
If you would like me to, I can scan the manuals and e-mail them off to you. I also have the frequency chart, but this would only be relevant for the UK/Ireland.

All the best.
