Summary – I am using this in a rack paired with my Mackie DL32R mixer. If you need multiple wireless in ear units for your band and don’t want to spend thousands of dollars, the PEM-04 is a great value. While I don’t notice any static and the physical range on the wireless is more than enough, the overall sound quality is “ok” at best. So if you are looking for studio quality dynamic range and clarity, you will be disappointed (more on this in detail below). The rack mounted transmitter unit is heavy duty, looks very nice in the rack and seems like it will last. However the receivers are cheap plastic material all around and I feel like they could easily get crushed in transit if not protected. Also the plastic clip on the back of the receiver - I feel like If I stretched it too much to go over a thick belt it would break off. Again, it’s a price/value issue. I think for the price, the PEM-04 offers a great value. In my opinion, this is for people just starting out as more seasoned musicians will probably want better quality audio.More details – Audio quality - Even though the specs say the frequency response is 20hz to 20khz, it not super well balanced. The mids and highs are strong and the bass frequencies are thin sounding. Imagine if the receiver had an EQ knob that went from bass on one end and treble on the other, it sounds like you have it turned all the way to the treble side. I have tested with Shure in ear buds and Audio Technica M50X headphones with about read more the same result. The rack mount transmitter has ¼” headphone jacks and when I plug in there it sounds better but the wireless receivers are very treble heavy on the sound. Overall, the Nady PEM-04 does the job on the cheap but again if you want studio quality full range audio, buy something more expensive. Input impedance issues – This will likely vary based on your setup. I have aux outs from the Mackie DL32R plugged into the inputs of the Nady PEM-04 via balanced XLR (on the Mackie side) to balanced ¼” (on the Nady side) patch cables. In the Mackie mixer software, I have to turn the aux faders to -20db and turn the Nady receiver up to about an 8 to get clean audio. If I turn the aux fader on the Mackie to Unity (where it should sit) then I only have to turn the Nady receiver to about a 2 and its loud but very poor audio quality (distorted, etc). By comparison same settings going through the headphone jack on the DL32R when the fader is set to unity are crystal clear and full range. So depending on your setup, you will need to play with the aux output setting of your mixer vs the volume knob on the Nady receiver to get a clean sound. The sound will still be lacking on the low end, but its good enough to hear what everyone is playing.Wireless Transmit distance – The wireless transmit rage seems just fine (in my setup, the DL32R and Nady transmitter are sitting on the stage so we aren’t too far away from it). I feel there are more than enough channels on the unit to work around any other wireless that the band is using.
