Verified Customer zZounds has verified that this reviewer made a purchase from us.
I bought this unit to use on wedding ceremony gigs. Primarily for the judge/officiant, but also the groom if requested. I currently own several wireless handheld units in the SLX series. in comparison, I really wasn't sure what to expect performance wise as I assumed these are a step down in quality from my SLX units. From the very first time I used the BLX unit, any doubts i had we're put to rest. These units work Great! The range is excellent and the audio is very clear. The CVL mic is just a $40 mic, but it gets the job done! I have a DBX 31 band on the mixer output to ring out a few undesired frequencies. For speech use, some EQ tweaking is a common thing. I would highly recommend changing the channels from the stock A1 and A2 setting. For whatever reason, Doing this gives you a higher & hotter gain signal. Other than that..... These units work really well. I'm very pleased with the purchase, And I now have faith in Shure's lesser expensive products. i have purchased several pieces of gear from zzounds and their support and service is excellent! -Steve
