I have just bought a velodyne eq max 8 sub

I'm running it with a Yamaha A1030 receiver, which does have a EQ setup with mic. My new sub comes with a EQ microphone as well.

I'm unsure how to best set this up exactly and which microphone to run first and all the buttons and dials on the back, could anyone be kind enough to advise please?

I had mine done by a pro, so not entirely sure about sub eq.

Sub should be set to 50% volume when running room correction, and crossover should be set to whatever you prefer. For most speakers it'll be 80-120. I've got mine set to 40 as my fronts go down to 28hz.

The knobs and buttons on the back you don't touch once it's set up.
 
As with anything there is a few ways to do this.

Using the mic you got with your amp
Set sub to say 50-75% volume. Crossover I normally leave to the default 80 that most amps set it to anyway. Then run the auto setup on the amp.

After that's done, run some scenes you know well and see how it sounds. Don't fell like you can't make changes to levels if you think it sounds better to you. Quite often to my ears, the auto setup on amps get things wrong, especially the sub. So get a good bass scene (Darla tapping on the fish tank in Finding Nemo is awesome for this) and play with the volume a bit till you get it sounding right for you.


Using a sound meter and tape measure
Measure out the speaker distances and enter them into the amp speaker setup. Then play the test tones, using the sound meter sat in the listening position to make sure they are all the same. I do like a little bit of a boost in the centre channel but thats just personal pref.

I do it this way but then im al old fart and do it old school :)
 
crossover on sub to max (receiver does crossover freq, cross over on sub is when having passthrough to speakers)
vol on sub to 50%

run setup on receiver
play a few vids tweak the sub settings on receiver (lvl and crossover freq)
 
correct so far, however you want to run the subs own EQ first, then run the yamahas eq setup.

vol on sub is not set in stone that it should be at 50%. It depends.

With AVR setup there is no need to do distance, as that is done by the delay to each speaker during AVR calibration.

Crossover on the subwoofer back panel should be bypassed or to maximum, as avr bass management does that.

But what do your surrounds and centre speaker go down to? It doesn't matter what your fronts can do unless you have no other speakers.

Crossover on the sub should be bypassed, or set to maximum. Crossover on the AVR ideally should be set to 120hz because that is the subwoofer LFE cut off, if you set it to below that

What speakers do you have?

On some AVR's you can set indepedent crossover per speaker pair. So you may have full range left & right, with semi-full range center, with limited range rears. So you are able to set crossover per speaker say 60hz for L/R/C then 80hz for side & surrounds, and anything under that (per speaker) is re-directed to subwoofer.

On other AVR's the crossover is for all speaker, so then you choose the crossover for the speaker with the highest bass response.
 
No +/- figure so that could mean anything. Most likely +/- 6dB, I doubt 10dB as that is area of junk speakers.

Have to take a guess, 2x8" ported speaker might not go that low. I'd add another 10-15hz on top of that.

what you have to think about is where do you want certain frequencies to come from.

for example in your current setup anything below 32hz is sent to the sub. anything between 32-40hz is sent to the centre speaker. anything above 40hz is sent to all speakers.

I personally would want maybe everything below 60-80hz being handled by the sub and then everything above the figure chosen going to all speakers.
 
yep some debate that all crossovers should be set the same, rather than mixing.

Problem with that, for music I like the L/R playing a bit lower down, say 40/60 hz setting, likewise sub for music lower down too. Or you could use direct but my unit doesn't have that feature for digital inputs, only direct with analogue input (that way full range for L/R, subwoofer not active, no bass management)

But for movies can get away with higher setting.

Plus with lower crossover point than requiring more power from your amp. Are you using seperates?

If you can, try and find proper report on those speakers.

I have a pair of speakers, they're 2x 5.25" mid/bass driver bipole, stand mount sized, ported, no +/- figure. It states 40hz response. Yeah right. Was tested and really 80-100hz or so in reality.

The pl300 spec sheet states 28hz. If you think that's wrong take it up with monitor audio.

It has no +/- figure, so they are padding that number out. By not disclosing that figure, then they can say 28hz. Not lying, just not revealing it, and they can use a lower figure.

Sorry but same as my bipoles, slightly warping the figures to sound better. Yes they are high end speakers not denying that.

But I have my doubts a tower with 2 x 8" driver can reach that low, typically. Unless it has unusual port system like transmission line, which can go very low for the cabinet size/driver size (compared to like for like ported box)
