Did using a mic change the way you listen?

I've been on the fence for a while now on getting a mic to calibrate my system. I, like most here I'm sure, love to tinker and am curious if it is more a toy to tinker with or if after using a mic, I'll be like "Wow, how did I ever listen to anything before this?".

I'm using an older Yamaha RX-V3300 receiver so my adjustment options are limited, but this unit is also pre auto calibration. So I figure the mic might give me a starting point, but I also know I like to run my subs hot just using my SPL meter. I guess my concern is even though the mic might tell me one thing, my ears may tell me another.

Calibration is more about learning what your ears are actually telling you. The problem is that you don't know. What you like has so many variables that you really have little idea how what you hear relates to any objective measure. When you calibrate, you learn some of this. You may discover that you like or don't like whatever target response you calibrate to, but at least you will have a reference point to work from.

Looking for me, just google my username. I have used the same one for most sites for many years.

Re: Did using a mic change the way you listen?

I like the Omnimic because it shows me, in real time, the FR of my system and how changes I make affect it. It's a great tool for optimizing speaker and sub placement, and determining what kind of tweaks to apply for the best / flattest response at the listening position.

Because you don't have PEQ setup is important speaker/listening position can help.

Other option is the UMIK-1 or UMM-6 from Cross-Spectrum (mics only) and they work with REW.

They are both calibrated from 5 - 25,000hz.

Basically Mic/REW will tell you what you need to know about your system/room.

This could be your cheapest upgrade.

Are you happy with the sound you currently have?

You could buy $20,000 speakers and have them setup/positioned wrong and you could buy speakers worth $2,000 setup correctly, and these will sound better.

OK, I'm sold. I'll being placing my order shortly.

I actually am quite happy with the sound I have now, but there is always room for improvement.

I couldn't agree more with the cheaper speakers being setup correctly could sound better. I've found that in my room just using the spl meter that a single subwoofer in the front corner has a better frequency response than multiples around the room.

Highly recommend buying from Cross - Spectrum.

You won't regret it, alot of fun trying to get that extra out of your system.

Would you say it's safe to go with the UMIK-1 at this point?

I know they were having some issues, but reading through the other threads it looks like those have been resolved. Plus with the CSL calibration, that should remove any ghosts in the system, I would imagine.

Looking on Cross - Spectrum thread Herb says that the UMIK-1 is the way to go, so to answer your question "yes".

If you are unsure drop Herb a email or post on his thread, see link below.

Thanks, I'm looking forward to seeing what I'm actually listening to.

Why does that seem weird somehow?...

Yeah quite true, a test for your ears.

I always thought that my ears were not that great, but soon realized that they were ok when measured and found out that the high end dropped of @ 5 khz.

Some things to think about:
1. Use the RTA in REW to find the best position/listening position for each speaker
2. Measure each main speaker to fine tune after finding these positions
3. Depending on gear if you have EQ and Distance settings set these up
4. Keep this in mind, when you are EQing 0 - 250hz you are EQing for the room, when EQing 250 - 20,000hz you are EQing the speakers, if this makes sense.
5. When EQing bass (0 - 250hz) apply EQ filters to both speakers playing (mono).
