BLX1 Wireless Bodypack Transmitter H9 Band (512–542 MHz) – Replacement Mic Transmitter for BLX4/BLX4R/BLX88 Receiver – Up to 14 Hr Battery, 300 ft Range

It works perfectly and sounds great. This one Replaces the transmitter I wore down after ten years of really hard playing. It is perfect. Just like my old transmitter pack. You can’t go wrong with Shure. I’m so glad this worked out for me.

Great product, great performance, crisp clear sound. In use now for a few weeks. I was worried about using regular batteries instead of being able to put this on a base to re-charge. 1 pair of good batteries like Energizer will last you 8 hours, the system says. Well I had it used for about 6 hours and changed the batteries NOT because it quit working, but because I felt it was going too long without a charge hahahah... so it was done for my piece of mind.

5-star all over.

Good product, just make sure you really know what the TV stations are using for their broadcasting. Consult with someone who knows all the available frequencies in your specific area.

The Shure BLX1 works well, with no dropouts or issues in a small theater environment. The price is right and they are easy to set up. We have had no failures or issues, but we also handle them with care. The plastic housings and battery doors are not as robust as the more expensive Sennheiser alternative. But as long as you use them appropriately you should have no problems.

This transmitter was ordered as part of a system to replace a a 20+ year old Audio-Technica wireless microphone system. Installation is easy, with no need to pick a specific MHz frequency band - just toggle through the available frequency settings and match with the receiver. Operation is simple with a sliding on/off switch on top of the transmitter. Sound quality of the system is excellent. When ordering make sure that the frequency band of the transmitter, designated by Shure with a letter and number ("H10" for example) matches the band for the receiver. 5 stars.

I purchased the Shure BLX1 Bodypack Transmitter less than a year ago; I am fitness instructor and use it along with the wireless headset to teach cycle classes twice a week. I wear the transmitter in a tune belt bodypack so that it is away from my body. Initially the product was great. However, after a short period of time, I noticed that the sound was deteriorating and would sometimes stop in the middle of a class. There was also some periodic hissing or what seemed to be a “bad connection” between the headset and the transmitter. I contacted customer service about the issue. They were very responsive and polite. I sent the Transmitter and Headset back for review and was assured that, as it was under the two-year warranty, they would fix it for me at no cost. NOT TRUE! The warranty, shockingly, DOES NOT cover the impact of sweat potentially corroding the connectors. These are designed FOR fitness instructors, who SWEAT. I was told that the $149 transmitter would cost $117 to repair … and it’s less than ONE YEAR OLD. Suggest you try a different brand!

Perfect. Exactly what we needed for out training rooms. I bought 2 of these to replace 2 of the same product that went missing. 3 years of relatively heavy use on the last set with no issues at all. I expect these will perform just as well as the last set did. FYI: We transmit with multiple microphones through 2 walls at a distance of about 100 feet with no issues at all.
