Is a fan mod mandatory on new NX3000D? Are these amps really that loud??
I have an Accuforce Wheel and its control box fan drives me nuts already.

 

[jayk]

oh nice, another location to try, I put mine close to the hole for the side harness, let´s say over the "K" letter of your sticker.
Time for testing, hehe

Let me know what its like, I was thinking that area also. I'm only running mine on 12% on the amp at the moment.

I´m trying to remember a website or app which played soundwaves to display charts, showing what Hz were the most useful for a particular exciter, does anyone remember?

I´m trying to remember a website or app which played soundwaves to display charts, showing what Hz were the most useful for a particular exciter, does anyone remember?

These are useful as a side by side theoretical but they represent what a transducer or exciter does solo. What you actually FEEL from exciters, and what Hz are most "useful" when you are in the seat is a combo of:

- the exciters characteristics
- the amp that they are attached to
- the resonant frequency of the seat
- your weights impacts on isolators as that impacts the extent to which other parts of the rig become a part of the system
- your BMI / mass as YOU become a part of the system

So, those charts are a useful reference when comparing products but less so to tell you how much the energy they transmit will be perceived in any give application. For that, SIT IN THE SEAT and connect your phone to the amp with a frequency generator app. You can

- vary the Hz being passed as a single signal so you can get a subjective feel for what Hz are most "useful" in that you perceive the most energy
- most apps allow more than one frequency, so experiment by setting one where it feels like you are getting most energy and add another frequency. Move that around and feel the result. In other words experiment to see how the transducer can deal with doing two things at once.

This is really useful for dialing in effects. No two setups are unlikely to be exactly the same, hell the same setup isn't even the same for two people with significantly different density / mass. It's not going to be night and day different, but if you're trying to dial an effect in to the best Hz, it matters.

Thanks I will try a phone app while seated
are you calling me a fatty, by the way???

 

[Mr Latte]

I used this one a lot (PC) you can generate different frequencies for L/R with independent volumes and bring up a display of the Hz as well as easy Hz adjusting slider. You can also create tones and durations (sub tests) and save these as WAV.

See Here (free demo)
It may be more scientific or professional than some apps for phones/tablets
Not looked in a while to see what are the best tools on android/ios.

You could also use this RTA (free demo) to monitor frequencies.

THIS is an awesome website tool for generating audio to test or just have fun with. Has over 200 sound generators. Simply connect or duplicate the output of your "Primary Audio" soundcard to enjoy with tactile.

Silly/bad idea removed....

Oh my. Have you found any PC based ones that can send different signals to different channels? That could lead to all sorts of interesting experiments for multichannel effects.

Audacity lets you generate tones and place them or general audio to whatever channels you want along a time-line.

The primary benefit with doing tests with tones is mainly that the user can help determine what the lowest Hz they can feel good are, as well as what Hz may peak and what Hz are the limit that they feel with their installation. Doing tests with different gain settings to determine these. The user may also discover what Hz then also resonate in their seat/rig.

If you do that as groundwork then you now know the dynamic range that suits the installation and hardware you have. It then makes sense to use frequencies for effects that are within that range.

Hello @Alvaro de la Orden
What kind of 3M VHB you use ? Do you have an Amazon link ?

I am considering buying 4x Dayton Audio DAEX32EP-4 Thruster 32mm Exciters (40w 4 ohm) ($20 each)

The only problem is that i am using a (Sparco R100) seat, so i do not know if it is possible to mount the exciters to this seat somehow, or maybe another way to use these exciters as they are cheap and seem to work really well apparently.

I do not have any tactile feedback atm, using a simlab p1 rig and sparco r100 seat....

 

[Alvaro de la Orden]

Just ordered another Amp to power my last two exciters.
First location to try will be under my legs, close to the knees.
No isolation for my seat yet, struggling to find them

@Mr Latte could you weigh in on my thinking on something? I don't want to put the build hours in unless I know a change might be worth it.

I enjoy pedal board tactile and have tried various things. Smaller shakers don't have enough oomph to register compared to what I have on the chair but this BK used as:

- mono front bumps
- mono front wheel lock
- some burble when revs are low

manages to have a meaningful impact without overheating (which has been my big issue with this BK - now brought back to life thanks to a 50 cent thermal fuse replacement)

What are your thoughts on going after a strong stereo feel for pedal board? Is it achievable? Seems like the design of a pedal set focused on rigidity will suck the life out of stereo separation, right?

Have you ever tried separating pedals onto individual isolated platforms, e..g Clutch vs Brake+Gas so the energy is being directed to left and right heels and toes?

 

[Mr Latte]

Its possible yes, but to get the best results from pedals you want two individual heel/foot platforms that are isolated from the main rig. These can then have other antivibration materials applied and the tactile connects directly to each one (L/R).

Spoiler: M O R E ?

Ideally what you want is that the horizontal surface or bridge that these supports are connected to is not offering easy transmission between each channel. This is the main flaw in most installations adding tactile to pedals, that often do nothing or very little to maintain L/R side independence.

Imagine two sections of alu or steel plate, these supported with multiple cheapo isolators or more substantial isolators that will prevent the plate from having much movement. Beneath these, we have another plate but we also apply antivibration or sound-deadening materials. Then we have a horizontal bridge across a rig that each side of these foot/plates may be supported on.

The difference with something like this is that for the energy to travel from the left/right and vice versa it has to go down through the isolators/antivibration materials, then across the horizontal bridge support and then also once again through antivibration materials and isolators before it can be felt in the other foot.

This can greatly reduce any stereo crosstalk. You can still apply mono effects to each side if desired but it will improve the stereo effects sensations much better. Of course, some experimentation needs to be done to find what isolators offer good support and firmness when foot pressure is applied so in these we do not want much dip or movement.

Controlling The Flow:
A problem, however, is that if we have a link for the tactile to go beyond these foot/plates and into pedal sets then the pedals themselves will act as a bridge causing stereo crosstalk. So if someone really wanted to take this to a high level then it would mean having not just stereo based foot/supports that are isolated but also pedals that let us install each pedal stem individually and have it on its own isolated support from each other pedal.

For each pedal/support, it could have its own tactile and from previous tests I experimented last year, I did get some nice feedback on temporary test builds that used TST units for mid/high bass going to pedal stems and use BK units with lower bass into the heel/footplates. I have not tried yet using exciters in pedals but it likely can have some success if people already do this with small vibration motors on pedal stem sections.

We can increase the tactile presence entering or feet/legs if we can get good tactile to enter our feet from both the heel and toes. I focused on more low bass energy entering the heel but it also possible to enter in via the pedals stems but then also the energy from a TST unit able to move through the pedal stem support into the foot base supports.

Having more than one unit not only lets us combine effects into toes/heel also but it lets us place more effects better and not bog down a single unit so easily.

Hi all, I am currently running 2 shakers through a 2 channel amp in extensions mode in simvibe. I am thinking of getting a 4 channel amp so I can run simvibe in chassis mode. I have my current 2 channel amp plugged into the sound card but how would I connect a 4 channel amp such as the nx4 6000 to the sound card? Secondly how would I connect the output to the shakers?. The nx4 6000 has the locking style output connectors, how do they attach to the shakers where you use wire and strip the end of the cable shroud off them to poke through the connecting post?
Cheers

That Soundcard your have your current Amp connected, you need to setting it up for 5.1 or 7.1 channels, so you can use another output from Soundcard to new amp

Okay, do you know if you can mount rack type Amps vertically? I am thinking of getting the nx4 6000 Behringer amp but only have a narrow space to put it in. Is there any issues with vertical as opposed to horizontal mounting?

No idea sir.

Regarding my simrig, antishocks are arriving this week, I need to isolate the seat from rest of rig
