Oscar delivered!

Recommended Posts

There've been lots of discussions about the Oscar Sound Tech lavs…how do they sound, how do they compare, etc., etc. Well, I just put my recently purchased TL-40s through a great test and (spoiler alert), they passed gloriously! I had the opportunity to mic and record two singers doing operatic-style vocalizations. As they went from loud to louder across the full range of their voices, I held my breath expecting to hear over-modulation or at least some peakiness during the exercises. They got so loud at one point that I had to stop them to turn down the inputs on my transmitters. But no matter what level or frequency hit those OST lavs, all I heard was smooth, clean response from them. Overall, I'm quite impressed with their performance in that situation.

I like my TL-40's. They are a good step up from stock Sennheiser mics for sure. Still, I find them a bit bright, almost brittle on the highs. That being said, the stock Sennheiser mics are just mud in comparison. I'd take a little too bright over muddy, useless gack any day.

Well there have been several discussions about how great the Oscar soundtech lavs sound great as I own several. But can anyone chime in here. He referred to it as "overmodulation" I thought overmodulation as a term was only referenced when consider radio telecommunication style systems. I had a discussion with someone recently when he mentioned overmodulation as when his boom was peaking, and I said that I've not heard many reference just a general peaking or distortion as overmodulation although it technically probably is. I equated it to intermodulation and said that I usually only use that term when it is applied to radio communications like, "I'm having issues with intermod", or "I think the transmitter is overmodulating on me" or something of that nature, like the OP used in this circumstance. Do any of you say I overmodulated that one...when considering just general mixing? lol Might be funny but the way the camera guy said it seemed weird to me.

When referring to the performance of the MICROPHONE, overmodulation is probably not the right term. A more relevant observation or measurement would be one that assesses when the mic capsule overloads --- exceeding the SPL (sound pressure level) the microphone can handle. If, on the other hand, what is being reported is that the specific mic going into a transmitter didn't push the transmitter into limiting or compression (in comparison to other lavs used) this is probably a function of the sensitivity of the lav, it's output level.

Oops, if I misused the term "overmodulation," Tim. I was really referring to any possible distortion throughout the entire signal chain including at the mic, the transmitter, the receiver, or the mixer input. My background "other life" was in the music biz, producing and engineering records, and we commonly referred to over-modulating the analog tape when making loud rock n' roll records!

Over modulation refers to a carrier signal so it technically can only refer to part of the signal chain after the microphone has transduced the sound pressure waves into  audio signal.  The correct term for too high of an SPL at the microphone would have been "overloading" or "clipping the mic."

That being said I know exactly what you meant.

Anyone had issues with build quality?

I've had to send 2 out of 3 back for repairs.

Customer service is good though.

Hell yes. I've had a multitude of issues with one I bought for Lectrosonics. Too much noise when "off-axis" causing the 200 to pump. Then when I converted to Sennheiser the cable once in a while starts crackling.
