The input gain is adjustable in hardware - +4dBu, -10dBVMy system that I am building will use the Sony RSXGS9 as the source. This means I need to use the analog RCA outputs from the source.
Does the APL1012 have adjustable input gain?
Why is digital preferred?
The Sony RSXGS9 has an optical out but it is lower quality than the analog out, and the digital output has no volume control. It is 0 dB FS always. No headroom for processing.
It is time to ask your friendly car audio shop for help in that.This thing is incredibly cool but unfortunately, due to the complicated tuning process and price. Im not sure how many people can actually afford/have the know how to use this.
Can I use the "Focusrite Scarlett Solo USB Audio Interface (2nd Gen)"?For quick measurements, I also use the Scarlett 2i2 mic preamp though for more extensive measurements I pull out the MOTU 1248 mic preamp.
The Scarlett Solo would work just fine. I took a quick look at the specs and they were basically the same. I bought the 2i2 because sometimes I do a hardwired loopback to compare the signal output (if analog) to the mic measurement.Can I use the "Focusrite Scarlett Solo USB Audio Interface (2nd Gen)"?
Should the USB not work, then it looks like could also come out of the Headphone jack to a 1/2"to 3.5mm and then into the mic port on the MacBook...
One could always start out with the software and see if it was to their liking?So. Whats the total price on this thing to have a fully running set up? Someone said earlier $1800 euros so thats $2k and then how muxh for tda and whatever else?

It is more significant in cost than just sticking a toe in the water... more like the whole foot. But it could be a way to ease into it. Maybe it would also work for miniDSP FIRs?
As far as the DSP part....
I found three or four units that were FIR based.
All pass filters go a ways towards addressing phase, as well as speakers that are well behaved and crossovers that do not have wild phase excursions. However FIR based DSPs are techicnically a more straight forward and better approach than IIR based DSPs.
... whether one can actually hear the difference, is another discussion.
There are undoubtedly good IIR based systems, and also systems running no DSP. So a FIR based DSP is not exactly required.
If you reread it, you find it does answer a lot towards the question.Doesn't answer the question
Sorry for misunderstanding... If you are glad for your existing setup and have 100% satisfaction with the carsound quality, why you spend your time on this forum instead of having pleasure by listening your stunning system?Or if your system is already stunning, then it will not make 1800 euros worth of difference, or whatever the price is... it will make no difference
If you think that we are "understanding each other in this Point", Then My post must have been poorly worded...Sorry for misunderstanding...

APL technology has changed mind of many enthusiasts despite their pervious experience in the audio World. Carsound is not an exclusion.
Sure, 1800 euros is a lot of money and one has to think about before investing in new components... But let listen first to what APL technology could make before final decission.
APL1012 for sure is not for newbees, but with the help and support from Raimonds, nothing will be impossible even for them.
But again, perhaps it is simply a wrong timing to change the stunning system. Especially if you made it by yourself and now it is time to enjoy it. Fully understanding you in this point. Good luck!
You should direct the Workshop not to touch (equalize) the curve in your SSF region. It means - set to "flat" that region with some gain. That is avilable by use of "low frequency limit" parameter in Workshop which is setting the gain for LF region and making curve flat.General question; Since I am using a ported subwoofer my port tune is 33Hz, so I have the SSF on the amp set around 27Hz.
When using Workshop, the measurement I assume will reflect the percieved bass slope and try to compensate to match an EQ curve, which usually keeps a flat response to 20Hz, thus defeating the purpose of the ssf? So am I wrong in thinking when making my own custom EQ curves, I should build a high pass about 25Hz into the curve so APL doesnt try to boost below my ssf?
Also, the APL1012 the clipping lights on the output panel - what exactly does this indicate (aside the obvious), and how to fix should it be clipping?
As in when your done with the workflow described in the manual, and performed measurements as uniform as possible, the soundstage will sound equivalent whether one is sitting the the driver seat or passenger seat of a car?APL measurement/tune are not seat (place) orientated in general.
Stage will also depend on distance (time alignment ) values you input relative to seating position.As in when your done with the workflow described in the manual, and performed measurements as uniform as possible, the soundstage will sound equivalent whether one is sitting the the driver seat or passenger seat of a car?
