Portable Sound System Ideas!

A friend reached out to me recently looking for some advice on a small, portable sound system to use for his duo of acoustic guitar and the puerto rican cuatro.

One of the instruments had a pickup and the other a microphone was used. In addition to a speaker needed close to their performance area, an additional speaker was needed to cover another room in the restaurant.

Knowing ease of use, affordability and portability were high on the list, I suggested the following.  I hope this can help you, too!

Small, powered 8″ speaker

– Small Mixer
– XLR cable and AC




Cleaning In Ear Monitors (How to clean IEM’s)

Nicholas Radina IEM Cleaning Tools

Ensuring In Ear Monitors (IEM’s) are clean, holes unclogged and all drivers are working can save you precious troubleshooting time and gain some confidence in your mix –although not the most glamorous daily task. This quick post will show you how to clean IEM quickly with just a few tools and a bit of time.

My tools and steps to clean in ear monitors:

“Cleaning Solution”
This concoction was recommended to me by my audiologist for flushing out ears — equal parts 91% isopropyl alcohol and white vinegar. I dip a lint free rag into this and wipe down each IEM before attempting to clean out any impacted holes.

Tip: Be sure to warm up the solution for 10 seconds in the microwave before flushing out your own ears

IEM Cleaning Tool
This tool, often included with your IEM’s, has a small loop and a brush. I dip the loop in the cleaning solution and clean out the holes. The brush is good for hard to reach places. I’ll then use the Jodi-Vac to suck out the remaining wax.

Listening Tube
Wouldn’t it be great to be able to listen and test each IEM driver?  I simply play pink noise into the IEM in question, then “probe” each hole to listen for proper function. This tool has saved me so much troubleshooting time when an artists says something is “wrong” with her ears. You would be surprised how many IEM drivers are blown and the artist tries to accommodate not knowing the failure.

NEW!! I offer a very simple and affordable listening tube you can order directly from me!

TIP: Be very careful with the metal probe — only do this once the ears are CLEAN. You don’t want to push a blockage deeper into the IEM canal.

The fine folks at Sensaphonics in Chicago also offer a nice molded version for their customers.

Jodi-Vac Cleaning Pump

Primarily used to keep hearing aids clean, friends at JH Audio recommended Jodi-Vac cleaning pump . I use the “Consumer” model which seems to work just fine yet the is also a great choice. Just be sure to keep the tip and tube clean. I tend to dip the needle in the cleaning solution and then, while the pump is on, plunge the needle into the cleaning tube. Seems to do the trick.

Silica Gel Packets Desiccant Dehumidifiers 

After the show, try to let your IEM’s air out a bit before putting them back in a case. I tend to throw a Silica Gel Packet (Desiccant) in the case. This helps combat moisture. Quick and easy. Tip: Grab the “Indicating Packs” if you would like to keep an eye on when the pack no longer is absorbing moisture.

Flashlight
This process is best done in the daylight but the take away is you want to have plenty of light to see any other issues BELOW the hole opening. IEM’s come in many different colors— some easier than others to see the “tubes” within the IEM.

I hope sharing my workflow is helpful to you. Please let me know if you have some other tips for cleaning IEM’s.
