I'm a noob when it comes to setting up a 2.1 system with proper bass management and EQ. How do the 2 channel guys implement a line level crossover between the subwoofer and main amps, a high pass filter for the mains, and equalize it without having a separate analog preamp?
I've been leaning towards the SMS-1.
I am simplifying my system from 5.1 to 2.1. But the move has proven to be more complicated than I thought it would be. My system currently consists of: Parasound 2100, 2x Emotiva UPA-1 amps, Selah Prestigio(sealed), 2x Epik Empires, Emotiva XDA-2 dac, Oppo DV983 CD player, PC, Mac, PS3, cable etc.
Now that I don't need HT bypass, have only one [analog] source(the XDA-2, which handles all of my digital sources) and don't have a turntable anymore, I'm thinking about eliminating the Parasound 2100 and buying an SMS-1 to use with my XDA-2, which only puts out fullrange signals. I believe my speakers have a -3db @ 75hz. Does anyone have experience using the Velodyne SMS-1 as a crossover? Since the XDA-2 has both XLR and RCA outputs and both my subwoofers and main amps also accept both, there will be a couple of ways to hook everything up:
1: XDA-2>XLR>UPA-1 and XDA-2>RCA>SMS-1
2: XDA-2>XLR>SMS-1 and XDA-2>RCA>UPA-1
The above options will keep the signal to the UPA-1 short without risk of altering by the SMS-1. But, my mains will be receiving a full range signal, which supposedly puts more stress on the amp and can adversely effect the midrange as the smallish drivers attempt to reproduce midrange and bass.
3: XDA-2>RCA>SMS-1>THRU(untouched full range signal)>UPA-1
4: XDA-2>RCA>SMS-1>OUTPUT(above 80hz)>UPA-1
Option 4 seems appealing because it doesn't send the bass under 80 or so to the mains, but I am unsure whether the SMS-1 re-digitizes the whole signal or just whatever is under 80hz.
Another problem is concerning how I will play the test tones out of the SMS-1 as it outputs the test tones in analog only and the XDA-2 only accepts digital signals. Should I use an ADC? Run it through my Parasound 2100 before removing it from the system?
If anyone has experience using the SMS-1 any thoughts would be appreciated, especially if you have put a full range signal through it and used its crossover. I am interested in whether the THRU signal actually sends out EXACTLY what it receives and if the high pass crossover is of good quality.
Is there a better way to EQ the subs and do bass management(crossover) without spending a ton of cash, like an Outlaw ICBM and a cheaper Anti-Mode?
Lastly, would the XDA-2 volume control perform as well as a pure analog volume control? I've seen posts saying that the XDA-2 and XSP-1 have the same volume control.
Coming from a 5.1 system with 4 amps, a pre/pro, a separate analog pre with HT bypass, 2 subs, and multiple sources, I never thought a 2.1 system could be so complicated.
I know this may sound like a newbie post, so any comments or suggestions would be appreciated.
