Summary of Post: The product manual of the RX-5502 AV Receiver and several reputable websites, specify the RX-5502 output power at: 100W X 2. However, the product is sold on amazon as 100W X 4. Even though the product manual insist on a 100W X 2(only a pair of speakers driven), some information in html charts, from reputable websites, specifies the RX-5502 at 100W X 4 However, another html chart from the reputable Sheerwood AU site specifies the RX-V5502 at 100W X 2.


An informed shopper will find it difficult to purchase this item unless the perplexing contradictory information is clarified. Hopefully this post will prevent a shopper looking for 400 watts from buying a 200 watt product.


If anyone understands why there exists contradictory information regarding the power rating output of the Sherwood RX-5502 AV Receiver, please add a post to this thread.

End of Post Summary.


Post Begins:


The Sherwood RX-5502 is an AV receiver advertised on amazon as 100 Watt x 4 RMS. However there are pieces of information on several reputable places on the internet (including an official Sherwood website and the RX-5502 manual) that specify the Sherwood RX-5502 AV receiver as 2 X 100 W.

The product manual from the official Sherwood AU website specifies the RX-5502 at: Power Output - Stereo 100W x 2 (20Hz-20kHz, THD 0.08%) @ 8 Ohm.


Please see for yourself the power rating of the RX-5502 on page 22 of the manual (two links for the manual are provided) :

The Sheerwood America website specifies the RX-5502 at Output Power : 100W X 4Ch(1kHz, THD 0.08%)@8 Ω. However, on the same Sherwood america webpage, one can click on the EU product manual and see the product is rated at 100W X 2(only a pair of speakers driven).

I suspect the confusion lies in total watts (400) vs. watts per channel (100). As Maagguss says, however, if all four are being driven the measured maximum output is likely to be less.

The Sherwood method of rating power output is the same as used by the major brands of Denon, Onkyo, Yamaha, Harman/Kardon..

They state the power output into 2 channels even if the AVR is 5.1, 7.1, 9.1 or 4 channel such as the Sherwood.

In their spec/feature disclosure for advertising they tell you the # of avaialble channels...


Next if one wants to dig deeper, in the older days a few years back...

The brand would disclose power output driving ALL available channels simultaneously....

But those days are gone...


Just my $0.05.... 👍😉

Several reputable sources on the internet specify the RX-5502´s power rating at 100WX2. However, the majority of these reliable vendors DO NOT clearly specify that both A & C have 100W X 2 capacity, for an overall total of 400W.


Does the information provided leave room for doubt and confusion?
