Da jeg nu har haft et sæt MS4 på besøg ville jeg høre om nogen ved hvor meget effekt en AVR8500 smider ud i 4 Ohm ? Iflg. manualen leverer den 2 x 125W i 8 ohm, men den siger intet om ydelsen i 4 Ohm. Nogen der kan hjælpe ?

er rimelig sikker på at harmans forstærkere fordobler effekten, når man halverer impedansen.. så kan du selv regne lidt

hej acer
nu har jeg selv kun 7500....mener der står i den medfølgende brugsanvisning at der ikke må kobles 4 ohm på...men jeg kan jo huske forkert????

mvh Velkommen

Mindes at jeg lige har læst i et high fidelity blad, at witzel har ret..

whauu.....250W ? Det var derfor MS4 var så livlige

LAB RESULTS

Manufacturer's stated output: 110W (20Hz-20kHz, 8ohms, 0.07% THD, multi-channel mode)

Measured power output (front channels, two driven) @ 1kHz: 155W (8ohms, <0.5% THD) 255W (4ohms, <0.5% THD)

Fidelity firewall (front channels, two driven): 150W @ <0.1% THD (8ohms)

Distortion at 50W (front channels, two driven): 0.0033% (8ohms, 1kHz)

Frequency response (front channels, two driven): 20Hz-20kHz ±0.12dB

Measured power output (front channels, five driven) @ 1kHz: 125W (8ohms, <0.5% THD), 185W (4ohms, <0.5% THD)

Measured power output (centre channel, five driven) @ 1kHz: 130W (8ohms, <0.5% THD) 180W (4ohms, <0.3% THD)

Measured power output (rear channels, five driven) @ 1kHz: 120W (8ohms, <0.5% THD) 175W (4ohms, <0.5% THD)

Nice, så var witzels opgivelser ikke helt hen i skoven
