So, I am feeling math challenged this morning despite the coffee so am asking for some help.
I drive my QRX212 HF (bi-amped) with one channel of a QSC PLX1602.
I have my DSP set up for this.
I need 2 more channels of amp in the rack with no available space.
I am considering the Behringer 4 ch amp as a solution but am trying to figure out the DSP gain changes I need to make for the substitution.
The specs as I could find them...
The PLX1602
Voltage gain = 40x (32dB)
Input sensitivity, V RMS
Full rated power at 8 ohms = 1.2v (+3.9 dBu) = 300w
Full rated power at 4 ohms = 1.1v (+3.2 dBu) = 500w
The INuke NU4-6000 (4 ch mono mode)
Max rated power at 8 ohms = 440w
Max rated power at 4 ohms = 860w
Input sensitivity for rated power into 4 ohms = 0.775 V (0 dBu)
Any help would be appreciated. Thanks.
