signal generators and...


Is there a device that can show me numerically what frequency I am generating at a given time.I am using a rolls signal generator and while it works fine I would like to see where the problems are and solve them with a parametric eq.I'm figuring it would have to run parallel with the signal output.This would make it easier to kill room modes faster.

Subject: English chosen as the official language of the EU!

London (AP) -- The European Commission has just announced an agreement whereby English will be the official language of the EU rather than German, which was the other possibility.

As part of the negotiations, Her Majesty's government conceded that English spelling had some room for improvement, and has accepted a 5 year phasein plan that would be known as "EuroEnglish".

In the first year, "s" will replace the soft "c". Sertainly, this will make the sivil servants jump with joy. The hard "c" will be dropped in favor of the "k". This should klear up konfusion, and keyboards kan have one less letter.

There will be growing publik enthusiasm in the sekond year, when the troublesome "ph" will be replaced with the "f". This will make words like "fotograf" 20% Shorter.

In the third year, publik akseptanse of the new spelling kan be expekted to reach the stage where more komplikated changes are possible. Governments will enkorage the removal of double letters, which have always ben a deterent to akurate speling. Also, al wil agre that the horible mes of the silent "e's" in the language is disgraceful, and they should go away.

By the 4th yar, peopl wil be reseptiv to steps such as replasing "th" with "z" and "w" with "v". Diring ze fifz year, ze unesesary "o" kan be dropd from vords kontaining "ou" and similar changes vud of kors be aplid to ozer kombinations of leters.

After zis fifz yer, ve vil hav a reli sensibl riten styl. To mak it ezir to red, al nowns wil bekum Kapitalizd. Zer vil be no mor Trubls or Difikultis and Evrivun vil find It eze to understand ech Ozer.

ZE DREM VIL FINALI KUM TRU!!
Kg, Are you using the Rolls MO2020 generator? I have one and it is a great tool. In general, all you need is a sine wave generator and SPL meter. If you really want to go at it, a frequency counter and the above mention would give you best results.

Alfredo,
Yes I have the same rolls as you.It is a great unit but, what I think is happening while I am sweeping the bass frequencies and adjusting room modes with my parametric is....
I'm not catching the whole mode and just taking a slice of the middle.The Q is too narrow.What I would like to do is plot the room from 20-80hz.Then adjust the room modes, width proper.Sounds crazy but I'm a freak about the bass and something is wrong.I will be able to see the mode rise and fall.I have two that are close together due to the rooms 13.5 x 15.5 lenth and width.Sean gave me a great link to a multimeter that has a frequency counter built in.I can now donate my old Army multimeter to a friend and pickup the Tenma 72-4025.We shall see...39.95 what a deal.
Kg, what do you have other than the rolls? Are you using a SPL meter? What kind of speakers are they? Model? Floorstanders or bookshelfs? These could be some of the factors to consider but judging by the dimensions it look like is your room. Placing bass traps would help. A cube room is the worse place for bass modes because you have the same resonance in all six surfaces. If you want to learn more, go to Rives Audio. They have a ton of useful information. Alfredo
At this point I'm using stand mount monitors.All spkrs are set to small and xover at 80hz.It is quite simple to trouble shoot a room were the bass is xover to a single bass channel(LFE).What I would like is to get a better picture of the peaks and dips.At this point I can see them on my spl meter but I don't have a clue what frequency they are.Those test discs space the signals too far a part and it is difficult if not impossible to sweep.Once I get a frequency counter I can sweep and see what frequency and monitor with the spl meter.While I comment rives for his product and all his wisdom,analog parametrics have been around for years and to price a two ch. with only three bands per ch. at the price he charges I think he should drop the price.I would suggest a pro type for the sub and an eq for the mains.Just my opinion.He is a manufacturer who is overstepping his bounds in these forums.I don't know of any other manufacturer who advertises through forum posts.IMHO.
