Re: Phony 'Delivery' emails

You mean there isn't a warrant out for my arrest in (insert name of state I've never been to)?

And I'm not about to be evicted from my residence?

Re: Load on valve amps

I have a Peavey Classic 120/120 two channel tube power amp. On the Peavey users forum, it was mentioned that these use fly back diode circuitry to prevent disasters if a speaker became disconnected during use. I can definitely see the logic behind using the robust speakon connector.

Re: Load on valve amps

Don't forget that valve amps designed for live music may be damaged if turned on with no speaker attached. Tube Hi-Fi amps less so (depending on how the amp is designed.)

Time to play some Bananarama. Hottest chicks of '80's music other than Suzanna Hoffs (The Bangles).

RTA and Octaves

I'm using REW Room EQ Wizard for RTA. I have a selection of Measuring Modes, spectrum , octave , 1/2 octave , all the way down to 1/48 octave . If my EQ is only a 15 band (2/3 octave) equalizer, any reason to measure smaller than 1/2 or 1/3 octave ? I also have an FFT choice, 8192 , 16384 , to 13107...

Re: Calibrated Behringer ECM8000

The PC guys use TrueRTA. I'm on a Mac, I use REW (Room EQ Wizard). There's lots available, freeware and for purchase

Contact your mixers manufacturer and ask if it has phantom power to support condenser mics.

Re: Theory on Damping

Actually, I had read the thing about not damping everywhere on a forum that discusses old Altecs and Klipsch Cornwalls, so that makes sense.

Theory on Damping

I had my Cerwin Vega D9's (bass reflex design) open the other day and noticed damping material on just three sides. Looked inside my pair of JBL L100's, (bass reflex design) and saw the same thing. Damping on just three sides. Can there be too much damping? Is there something to this leaving one sid...

Re: Calibrated Behringer ECM8000

Both the Behringer and the Dayton calibration mics need phantom power to operate, this is provided by a mixer. I picked up a Behringer Xenyx 502 to do the job. Very inexpensive. Then the mixer's 1/4" output goes right into my computer's 1/8" input. Along with regular level adjusts, the mix...

Re: Amp/bass head for Omni15TB

I've a Eden WT405 I use with my O15(2x12 version). It's discontinued, but many are still on eBay. 250 watts @ 8, 405 @ 4, 650 @ 2 ohms. Ruggedly built. A bit heavy in the low frequency delivery. I have to EQ out a bunch at 21 & 32 hz so my woofers don't go bananas. A Thumpinator or 4th order BW ...

Re: Generators??

May be wise to hire an electrician for an hour before setting up. I am a commercial photographer and was photographing in a warehouse run by a large pull behind generator. The person from the warehouse was in charge of setting up the generator, and all my strobe power packs got fried. I got a hold o...

Re: Technique for speaker "burn-In"

All you need is a sine wave generator and a power amplifier. Keep the drive unit in free air. Set the frequency to about 75% of the expected free air resonance frequency of the drive unit and turn up the voltage until the cone reaches full excursion without making mechanical noise. Let it run for 5...

Just stumbled upon this thread. My table saw sucks, so I remember hearing about the Festool. Is the Makita the same?
