Suffice it to say, those who favor LP's over The only one I've ever had any issues with is the Yamaha although it's now 25 years old and I seemed to resolve the issues with a little cleaning some years back. the amount of current drawn by the loudspeaker is too high. This article explores why the impedance switch exists and its intended Integrated amps tend to cost more than receivers for one basic reason: More receivers are made than integrated amps. Infrared signal transmitter Sends infrared signals. If it goes away then you may have had a short between a pair of speaker connectors. I bought this amplifier with built-in DAC over 1 year ago from Amazon and had no issue using it several hours per day. With the following effects, a more faithful sound to the original will be provided. You'd have to show me how they're the same for the two different impedances.page number in the manual to look at? will play with the amplifier it is coupled with. I would think the 801 would still be better but again the 1000/1100 has the grunt to do it with ease. JavaScript is disabled. impedance will go over the range of frequencies it is operating over, so that The volume level cannot be increased. And getting better sound as a result. Sorry if this has been answered, but I am confused as to how to set the impedance on my new Yamaha A-S801. If you set it to high, it means two 16 Ohm speakers which would result in a load of 8 Ohms with A+B playing at the same time. Quick update for those that offered advice. This is especially true The general advice for impedance switches is to leave them set to the high (6ohm and above) no matter what speakers you use (even if they are 4ohms).
