miniDSP 2x4HD install and Setup Guide
My AVR already has dual independent sub outputs: (that I use for Front/Rear)
(So my *Distance/EQ/Phase Corrections are already in place for both Sub outs)
* The miniDSP will likely add some delay (as much as 4.5 feet) in your sub signal,
So you may want to re-run your AVR's room correction software (Audessey/YPAO/Dirac)
with the new mini in the chain and all filters set to bypass. (no EQ filters applied)
If you wish, you can use REW with the miniDSP to EQ your subs and set the time alignment (delays)
but I'm not going there right now in this thread. There's already a dedicated REW thread for that.
Sub-1 pre-out on the AVR will supply the signal for my Front Funk Audio 18.0's (into input 1 on the miniDSP)
Sub-2 pre-out on the AVR will supply the signal for my Rear near-field Subs and Crowson MA's (into input 2 on the miniDSP)
(USB cable running to my laptop is on the left)
The miniDSP Output 1&2 go to my Front Funk Audio 18.0 Subs (Left and Right)
The miniDSP Output 3 goes to the rear of my room where I split that signal with a Y splitter to my 2 VNF Velodyne Subs.
The miniDSP Output 4 goes to the rear of my room to feed my Crowson amplifier for my Motion Actuators.

Showing how my Front Sub Input 1 signal is feeding Output 1+2 (Signal is turned off for my Rear Subs and Crowson MA's (3&4 outs)
Rear Subs and Crowson's only get the Rear Signal from my AVR to Input 2 on the miniDSP (1&2 outputs turned off)
You can easily Matrix the in/outs to match your own configuration.
You may want just *1 sub signal input to the miniDSP and 4 outs with all the same output signal
...then go into each sub channel and set their own EQ/Delay etc. individually (You'll want to use REW for that!)
(you can also import the filters needed to get a flat response directly through the REW software)
* I have read that using both inputs on the miniDSP doubles the signal strength, (+6dB gain)
So if your AVR/Processor only has 1 Sub-Out...use a Y-Splitter to feed Both miniDSP inputs. (for non-HD model only)
The non-HD model miniDSP only has a 0.9v line voltage, the HD version has a 2.0v line voltage.
By Default the miniDSP 2x4 crossovers are set for High Pass BYPASSED only on outputs 1&3 for Subs, BUT set for Low Pass BYPASSED on outputs 2&4 for Speakers.
So you will need to manually change the Xover bypass filters on outputs 2&4 to match output channel 1 & 3 (the last two bottom selections) for using 4 Sub Outs
Channel 1 and 3 out are correct by default for Subs, just make sure all are the same now for 4 sub outs.
Next go back to the Input Channel page, select the PEQ Tab, (Lower Left corner, under Input 1) just above Mute.
That opens up 10 available colored EQ slots for making adjustments for BEQ settings (Frequency/Gain/Q/Filter Type)
The far right tab should read Low Shelf (aka LS) for the filter type. Some BEQ's will require a PEQ as your last entry, use PEAK as your Filter Type for those.
Unused EQ tabs should just be disabled by hitting the BYPASS button. (far right, bottom corner) turning the EQ color tab to Grey.
If there are any -/+ Gain numbers with a MV or N/A for filter type at the end of the BEQ...that's a recommended Master Volume change on your AVR or Pre/Pro
Some titles are a little too quiet, even at reference levels, some are already clipping before BEQ so the MV adjustment should be made
(relative to your normal listening levels)
If you want all your subs to have the same BEQ settings, make the PEQ adjustments on the Two Input channels, not the 4 Outputs
(both ways will work, but input channel is quicker (you only need to do it once if you clicked the Link Enabled tick box option to pair input 1 & input 2 together)
...just don't use both Input and Output when entering PEQ changes.
I Highly recommend reserving the Output Channles for your own House Curve adjustments,
That way each of the 4 output channel can have individual EQ, Distance/Delay and Crossovers for subs of different size, type, location
....or for motion actuators/buttkickers.
Each EQ slot has 4 Parameters for you to Correct: Frequency (Hz), Gain (dB) Q (Bandwidth) and Filter Type
If there is a Multiplier in the BEQ instructions (like x4) you enter the same parameters for EQ1, EQ2, EQ3, EQ4, before moving to the next frequency in the BEQ
Hit "Connect" in the top right corner of your screen to update the new BEQ settings to your miniDSP (Green check mark in screen shot below)
Then click the "syncronize now" selection if you get a popup. Once you are up and running, you can unplug the USB cable from your laptop.
...or leave it hooked up to monitor your 4 sub output levels in real time
If you want to switch between 4 different memory modes using an IR remote,
make sure the side of the miniDSP with the IR receiver (and the blue light) is facing your seat,
(cover the LED with black tape if its too bright)
I used the miniDSP remote ($5) to toggle between BEQ adjustments saved in Memory slot 1
and have my 2nd memory slot saved with my Sub 1,2,3 channels Muted, only active channel is 4 for my Crowson MA's
This is perfect for late night viewing as it delivers seat shaking bass effects without shaking the whole house. (Stealth Mode)
Memory slot 3 I use for regular TV viewing, so all EQ levels are set to bypass.
My USB cable isn't quite long enough to reach from my miniDSP to get my laptop back to my seat,
...so my next purchase will be a miniDSP WiFi adapter WI-DG (to keep my laptop "On" my laptop) ...$75
Thanks Nalleh! ORDERED!
...also ordered up a heavily discounted/discontinued "Alexa Friendly" Yamaha RX-A3070 AVR (NIB)
that was on close out, to replace my 3 y/o RX-A3050 (3050 had no Alexa and no Dolby Vision support, time to let it go)
I got it all hooked up, But the instructions for the WI-DG are a little wonky for PC users.
In order for your wireless Laptop to find the WI-DG in your available network connection list,
You have to first download the i-Tunes app for Windows users from the Apple online store (free) to get the mDNS service installed on your PC.
..You cant DL it from any other source, it has to be the version on the apple site Here: http://www.apple.com/itunes/download/
So I did that, and got the miniDSP-Wi-DG_221D52 added to my list of wireless networks available, connected to that,
the next step is to use a non-microsoft browser, like Firefox or Chrome, and enter http:// minidsp-wi-dg.local/
in the browsers url bar to load the password/login page for your WI-DG (a one time connection).
But it failed no matter what I tried, so I tried the suggested hard wire connection with an Ethernet cable, still no bueno!
I went online to the http://www.minidsp.com/forum/index
but got nothing there either,
Tossed everything back in the box and let it sit for almost a month. LOL!
Finally emailed miniDSP support to start a ticket, Two days later they said to manually enter the IP address (usually 192.168.100.1 works) instead of minidsp-wi-dg.local
They were right, instant connection. Entered a password I made up, switched from AP mode (Access Point) to Station Mode. Joined the WI-DG to my local network (wireless router)
Rebooted everything, loaded my miniDSP pluggin (miniDSP HD1 software on my PC) got the IP address using the Auto selection in the top right corner, Boom all Good!
But the following day experienced several connection drops, and the auto would make 3 attempts and often fail.
It took a while for Auto to find my IP to finally auto-populate, but I took note of the IP once it finally did, snapped a pic with my smartphone.
Now when the signal drops and I lose connection, I just manually insert that IP, in my case it was 192.168.0.20, and I get an instant stable "connect" every time.
...I turned Auto off.
Your IP address for the Wi-DG interface can be found on the System Information screen
Start your own Library of BEQ settings for your Favorite Movies
Enter the BEQ settings for your Favorites or for Movies you know are coming soon that you've pre-ordered.
Hit the Save button in the Top Left of the screen after each BEQ is entered, create a file folder named BEQ and start saving them to your laptop/pc/macbook
(Use the Load function to make entering BEQ's to your miniDSP a one click setup now
Here's a few I entered just while I was watching TV, it only took 30 minutes to enter/save 13 movies (~ 2.5 min ea)
... but now I can just hit the load button when its movie time
has compiled ALL the BEQ miniDSP files from our BEQ list above
That you can download to your own computer now, so you will be able to load them dirctly into your miniDSP 2x4HD with a couple mouse clicks, no more typing required.
He's working on a way to integrate your personal house curve settings on the output channels, update coming soon. (for now you have to add those yourself)
GitHub link complete with ReadMe instructions: http://github.com/bmiller/miniDSPBEQ
Just keep in mind, if you've applied personal house curve EQ adjustments to your miniDSP's output channels,
they will have to be added when using downloaded BEQ files (that are left neutral on the output end)

This is all you have to do:
1.) Rip movie to your PC using makemkv (http://www.makemkv.com/
2.) In the beq designer (http://github.com/3ll3d00d/beqdesig...ases/tag/0.3.7
), select Extract Audio from the tools menu and select the mkv file.
3.) Click the extract button
4.) Click Add under signals and select the file that step 2 created
5.) Click preview and then ok
6.) Start adding filters until you are happy with the result. Most filters will be low shelf filters with a Q around 0.7-1.0.

This tutorial does not go into every detail. You may have to experiment in BEQ Designer to figure out exactly what each step entails. This will apply a simple BEQ with a single set of filters on all channels.
1. Extract Audio - Decimate but do not Mix to Mono. This will keep all of the independent channels.
2. Add Signals. You should now see a signal for each channel.
3. Link Signals - Make one the master and make all of the rest slaves. Now if you add filters to the master, all of the signals will get them.
4. Add Filters to the master signal. You should see the filters take effect on all channels on the PvA graph.
5. Check Headroom - Click the up arrow below the PvA graph. This will bring up the waveform graph below. Check the "Filtered?" checkbox. Now select each signal and make note of the headroom shown. One or more of the signals may show negative headroom. The negative gain you choose to add should be based on the worst case, so make note of which signal had the least headroom (or the largest negative headroom). Add a negative gain filter to the same master signal above to increase headroom so that it is no longer negative on any of the channels.
6. Remux - If you followed all of these steps starting with extraction, the signals should map to the filters automatically.
This tutorial was meant to be quick and simple. It won't answer every question for someone first starting with BEQ Designer, but it at least gives you the guidelines to follow as you work your way through learning how the app works.
1. You will lose audio objects in Atmos/DTS:X mixes.
2. Many mixes already have channels with little or no headroom without any filters added, so don't be alarmed by that.
3. If you check "Compress Audio?" when remuxing, it will encode the audio as FLAC instead of uncompressed PCM.
4. If you want to do per-channel BEQ rather than applying the same filters to all channels, simply skip the Link Signals step and you can apply different filters to each channel.
