How much power does the Nikko NR-1000 have with 4ohm speakers?

[Ben Rothman]

Hello everyone, I have a Nikko NR 1000 reciever and I'm wondering how manys watts per channel it gives out with 4 ohm speakers. With 8ohm speakers it has 60 WPC. On the back of the reciever underneath the speaker terminals it says "A or B 4 ohms to 16 ohms" it also says " A + B 8 ohms to 16 ohms" I know that means when using either speaker A or B I can run speakers from 4 ohms to 16 ohms, and when using two sets of speakers at the same time I can only use speakers from 8 to 16 ohms. If anyone has any information on how many WPC the NR-1000 has when using 4 ohm speakers that would be great.

Thank You!

"The output at 1,000 Hz clipped at 81 watts per channel into 8 ohms for an IHF clipping-headroom rating of 0.96 dB. Into 4- and 2-ohm loads (for which the receiver is not rated) the respective clipping power outputs were 82 and 40.5 watts. Using the tone-burst signal of the IH-F dynamic-head-room test, the output clipped at 111 watts into 8 ohms, 96 watts into 4 ohms, and 51 watts into 2 ohms. The IHF dynamic-head-room rating (8 ohms) was 2.32 dB.

At the rated 65-watts output (8 ohms) the distortion was less than 0.002 per cent below 5,000 Hz and was 0.0075 per cent at 20.000 Hz. At half power and one-tenth power the characteristics were similar, with slightly lower readings. At 1,000 Hz, the distortion into 8 ohms was undetectable, being below the "noise floor" at most power outputs. It was well under 0.001 per cent up to 70 watts, reaching 0.005 per cent at 80 watts output just before clipping occurred. The 4-ohm performance was similar, with the distortion being less than 0.0014 per cent up to 40 watts and rising to 0.04 per cent at 75 watts. The 2-ohm distortion became measurable at 20 watts, where it was 0.0027 per cent, and it rose rapidly from 0.016 per cent at 30 watts to 0.26 per cent at 40 watts."

Thanks for the reply!

NR-1000 made me think of the Onkyo TX-NR-1000 which was a very high end AV receiver from the mid-2000's.
