Auto-EQ tuning with REW

[merlin el mago]

Just bought 1 miniDSP balanced kit + 4x10 plug-in to run Auto-EQ tuning with REW, I have several questions:

I have micro ECM8000 & external soundcard M-Audio MobilePre USB with all cables to connect are both OK or I need other hardware?

The software for Windows XP/Vista I need?
-REW V5
-Adobe Air environment
-Net 3.5 environment

Wich voltage & current draws the miniDSP balanced kit?

 

[merlin el mago]

I read the manual 12V 150mA

hi , do you use the microphone alone with the board or do you need anything else to work with rew ?

 

[merlin el mago]

Micro, SPL meter & soundcard & laptop with REW.

 

[lduarte1973]

i´m not worried about spl level , i only want to check frequency response do i still need the spl meter ?

do you need anything to give ghost power to the microphone ?

 

[merlin el mago]

Yes you need the SPL meter or REW don't know the level pressure.

Yes a soundcard phantom powered for the micro.

thanks 🙂

My understanding is that you only need an SPL meter if you want a calibrated absolute SPL level on your FR plots. I accept that most people like this.
The way I do it is just read the FR data as +/- x dB from the peak.
I really don't care what absolute dB level I've measured, what I do care is how many dB is that mid-bass peak above the average.
I enter an educated guess for the SPL cal in REW

in this case a mic , soundboard and rew is enough then ?

The mic will need a phantom power supply - the simplest answer is to use a basic PA mic mixer. Check the REW forum elsewhere for info about this and getting it up and running.

REW forum says REW soft needs a SPL meter (don't needs to be calibrated only is for reference) or you really don't know when see the graphics the differences where to apply the EQ.

if i connect the mic to my bass amplifier (instrument) will it do ? it has a line out jack

 

[merlin el mago]

NO, you will need a mic preamp with phantom for the mic or a soundcard with mic pre with phantom.

 

[lduarte1973]

thanks i think all my doubts are cleared

 

[lduarte1973]

do you recomend any cheap package/combination , since i will only use these for minidsp ?

 

[merlin el mago]

I use micro Behringer ECM8000, soundcard+mic pre M-Audio mobile pre USB, SPL of a friend.

 

[lduarte1973]

any spl meter will do , one like this ?

Do you have Iphone, use SPL apps, REW onlyt need the SPL reading for reference

 

[lduarte1973]

no i dont , but i can buy one that isnt too expensive
