Will do a multisub config and have a 2x4 balanced version, in 0.9/2 V in, 2 V out. I bought the 4 way crossover plugin (recommended in a forum thread I read) but wonder now if this was wrong to buy, should I have bought the 2x4 advance? In the 4Way plugin I´m missing the inout/output matrix.
Been reading the “Using MiniDSP 2x4 to Time-Align Multiple Subs On One Channel before Room Correction” guide written by AustinJerry. Link:
According the guide one should first gain matching the sub, step 1, and in a later step determining the gain structure, step 7. Is this really correct, if the gain is off in step 1 it might cause damage to the miniDSP?
Anyway I did it the other way around. Now wondering if I should go for the 0.9 or 2 V input in the Minidsp since my output is more than 2 V?
Marantz SR 5006 stereo mode. pre-out sub set at 0dB, AVR master volume 0dB, REW -3dBFS, connected by HDMI from PC to AVR. Crossover 80Hz main / sub, Measured voltage on AVR pre-out sub connector: 2,4 V
If lowering pre-out sub level to -2 dB -> 1,922 V
If lowering pre-out sub level to -8,5 dB -> 0,902 V
After reading about measuring I tried to change the crossover to 250Hz and measured again, now I had to lower the pre-out sub level to -11 dB to get 0,882 V. I don´t know what crossover to use today so I left the -11 dB setting. Right or wrong?
Please also check these print screens, if it looks okey levelwise?
