Step 3 – Improve the HK Amp with the Match UP DSP:
I added the Match UP 10DSP Amplifier. This will get a bit complicated, since you want greater than the Amp. You want the Amp, the extra MEC Card as a result of we’d like 1 additional enter channel for our system, and the BMW particular wiring harness to wire it into the HK Amp and RAM module. That is what I ordered:
Match UP 10 DSP: https://www.audiotec-fischer.de/en/m…fiers/up-10dsp
Match PP-BMW 1.9RAM-HK: https://www.audiotec-fischer.de/en/m…-bmw-1-9ram-hk
Match MEC Analog In for UP 10DSP: https://www.audiotec-fischer.de/en/m…/mec-analog-in
The MEC Card set up into the AMP is fairly easy, take away 3 screws from the facet after which you’ll be able to take away the facet panel and slide out the underside panel of the amp, then pop within the MEC card, slide backside again on, and set up new facet plate that got here with the MEC with the identical 3 screws. DO NOT change the jumpers on the MEC card, there’s some verbiage on it within the directions with warnings however the default settings are what we’d like, so dont change something.
The wiring harness could be very straightforward, plugs to the amp solely slot in one spot really easy sufficient. The primary HK Amp plug and RAM Module plug are labeled so you’ll be able to inform what’s what. Within the pic, what you see is the HK Amp, however stacked behind the amp there are 2 different issues . The RAM module is the one behind the stack .. onerous to see it in photos. Each Plugs are on the left hand facet so they’re straightforward to get to. The entry panel appears small, however thats actually all you want.
Energy wires don’t include the Amp so that you want these. I bought this package beneath, although I solely wanted the ability and floor wires. I really ordered the 4 Gauge package, however 4 gauge doesnt actually match the inputs on the amp, so I’d advocate the 8 gauge package. Battery is within the again below the ground, energy wire doesnt hook on to the battery, it goes to the little crimson field beside the battery. Loads of youtube movies on the market displaying wire these . Straightforward peasy. This package comes with an inline 50 Amp fuse which is what the Amp handbook states we’d like.https://www.amazon.com/SCOSCHE-ICAK8…47&sr=8-3&th=1
In order that was the set up of all the things, subsequent is the setup and tuning of the built-in DSP within the Match Amp. This isn’t a tough course of, however there’s a lot to be taught. I knew nothing, and after just a few days of analysis whereas I used to be ready on the Amp I felt comfy sufficient to do it myself. This tuning entails setting the amp inputs and outputs, setting crossover factors, setting speaker delays, and tuning the sound curves for every output, and another issues.
You’ll be able to obtain a primary setup from the hyperlink beneath to put in as your start line, however this principally solely units the inputs and outputs which is good, however thats simply the place to begin. https://www.audiotec-fischer.de/en/m…ase/soundIndex
I’d not run this amp with out tuning it, so both tune your self or yow will discover a spot that does DSP tuning they usually can do it for you. Earlier than I tuned I had peaks and valleys far and wide, so with out tuning it is going to be louder for positive, nevertheless it in all probability gainedt sound excellent.
Lots of excellent docs and youtube movies about dsp tuning on the market and there’s no proper or unsuitable manner, however right heres what I used. Home windows laptop computer operating the DSP PC-Instrument from Audiotec Fischer to tune the amp/DSP, an iPad Air operating AudioContol MobileTools App hooked to a minidsp UMIK-1 microphone to learn the sound generated from the pink noise, and I performed the pink noise from my iphone over carplay. Used just a few pink noise information, however primarily used this 20 min one. https://www.kicker.com/test-tones
Im no knowledgeable on tuning, however I can attempt to reply any questions you might have. I nonetheless want to complete my tuning, so Ill attempt to get some pics of the method after I do it and add them to this thread. To this point although, the distinction is night time and day between the Match and inventory HK amp. In my restricted testing time, it will get extraordinarily loud and general sound high quality could be very excellent. Subs are nonetheless very loud, however you’ll be able to tune these down within the SW. I like the truth that you’ll be able to tune every speaker to sound precisely the best way you need it to and set the sound stage to be centered to precisely the place you are sitting. I presently have a reasonably flat curve, however I like a bit of extra treble so I must tune in just a bit bit extra and modify the degrees of every speaker.
So general, very pleased with this mod thus far. All collectively I am in all probability in about $3000 which is lots (add one other $700 for the B&W grills), however should you’re a loopy music individual like me I really feel it is cash effectively spent… the inventory HK system pissed me off each time I turned it on.
NOTES:
For those who get a message within the SW in regards to the MEC card voltage, you want to modify the Voltage setting within the DSP PC-Instrument to be “max. 11 / 3,5 Volts”. Screenshot beneath of that setting. This MEC card enter maps to the middle channel, you’ll be able to modify the acquire slider up some if you’d like extra quantity out of the middle channel.
Within the final screenshot, the field labeled #4 is the place the amp energy cable goes. For floor, there’s just a few good decisions over to the left facet of the battery fairly near the amp.
