I'm planning to upgrade my system, I almost selected the speakers and I'm now evaluating the amplifiers: audio source will remain a miniDSP 2x4 HD (maximum output 2.0 Vrms), and speakers nominal impedance will be 4 Ohm. I need some help in order to confirm if my understanding below is correct.
For the subwoofer I'm planning to use an ICEpower module, am I correct in calculating following maximum power outputs when using my source at 2.0 Vrms?
For the left/right channels I'm evaluating some Hypex modules instead:
Any help or clarification is really appreciated, thanks in advance!
For the subwoofer I'm planning to use an ICEpower module, am I correct in calculating following maximum power outputs when using my source at 2.0 Vrms?
- ICEpower 700AS1 (Voltage Gain: 27.4 dB): 549W
- ICEpower 1000ASP (Voltage Gain: 27.2 dB): 524W
- ICEpower 1200AS1 (Voltage Gain: 25.8 dB): 380W
- ICEpower 2000AS1 HV (Voltage Gain: 29.7 dB): 933W
For the left/right channels I'm evaluating some Hypex modules instead:
- Ncore NC252MP (https://www.audiophonics.fr/en/powe...ifier-ncore-nc252mp-2x250w-4-ohm-p-18419.html): with a voltage gain of 25.5 dB I should be able to drive it well over its limit (theoretical value 354W).
- Ncore NC502MP (https://www.audiophonics.fr/en/power-amplifiers/audiophonics-ap300-s500nc-p-18566.html): with the same voltage gain of 25.5 dB I should be able to drive it to a good 354W. The specs are confusing though, what does this mean exactly?
2.35 Vrms value is more or less matching with my calculation, but what does it mean exactly "RCA : 1.17V RMS"? Does it reach 2X500W @4 Ohm with 2.35 V or 1.17 V at RCA connectors?
- Purifi 1ET6525SA (https://www.audiophonics.fr/en/power-amplifiers/audiophonics-hpa-s450et-p-20205.html): here the gain is even more confusing, values below doesn't match with my calculation at all (i.e. 2.12 Vrms into 20 dB gain should result into 112W @ 4 Ohm and not the maximum value of 450W):
Any help or clarification is really appreciated, thanks in advance!
