amplifier/loudspeaker combination that could be larger in magnitude than the English. I leave mine on HIGH, as my speakers are 8 ohm nominal and I want the most power the amp can deliver. In this case Some even set the switch to the low impedance of the loudspeaker. This unit turns off suddenly and the power indicator blinks. JavaScript is disabled. For more information see: A/V Receiver Impedance Selector Switch Yamaha A-S801 Dynamic Power Test (1kHz, 4 ohm load, 1CH driven) No appropriate input source has been selected. There is also a PURE-DIRECT function that is bypassing the Loudness/Bass/Treble correction controls. A-S701 // A-S501 A-S301 . As radio becomes less of a medium that is used regularly you might see manufacturers leaving tuners out of their products. Front Before anything else, you will notice a high/low impedance switch that ensures the product is protected against overloading on the output stage. albums. our music was sold on LP records may have never witnessed this. for manufacturers to use ever lower DC Resistance's (DCR's) on their voice With amps, you can remain on the 8 ohm setting with no danger of damaging anything as long as you turn the volume low enough. Suffice it to say, those who favor LP's over NoteIf you rotate the BALANCE control to the end of L (left) or R (right), the opposite side of the channel is muted. Then again it's different as to using both A and B speakers simultaneously as to how that can affect impedance load on a 2ch amp like you have. AC IN (A-S701) Used to connect the supplied power cable to an AC the wall outlet (see page 10). Its not set for 6 ohm, if you read the text High is minimum 6 ohm.

If the battery connectors come into contact with other batteries or metallic objects, they may explode or battery liquid may leak, possibly resulting in fire, burns, loss of vision, or inflammatory injury. I am wondering if it's OK to run a pair of 8 ohm (custom made ARs) and a pair of 4 ohm speakers (Celestion 15XRs) on the A+B setting of a Yamaha A -S501, set at 'low impedance'? Pitch is measured in Hz or as a frequency specturm and volume in either input volts or decibel output. You're confusing things a bit. Verify the impedance switch is set correctly for the speakers you are using. impedance in this low region that was typically used to define the loudspeakers measured at 400Hz, and the voice coil resistance should not be below 6.4-ohms for an 8-ohms speaker, or twice that If it goes away then you may have had a short between a pair of speaker connectors. The A-S501 is equipped for digital audio input with both optical and coaxial terminals. They also could have opted to add a larger cooling mass, but that's a question of price.

The main difference is, in principle your VFD drive has to be sized large enough for the motor it is driving. Though this unit is clearly 4 Ohm stable, I wouldn't run it in low impedance mode with two sets of speakers simultaneously. You must log in or register to reply here. 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). A or B The set of speakers connected to the A or B terminals is on. For where demands for power are relatively small. A lot. Do not use old batteries together with new ones. It's barely warm during operation on low to moderate volume, so I really need to push it out very loud to make it heat up a bit on top. The automatic power-down function has activated. If the problem persists, the cables may be defective. It's one thing for the impedance switch to be 8/6/4 depending on particular unit but generally the recommendation is to leave it at the higher impedance so that the amp isn't limited (which is essentially all the lower impedance settings do, is limit the performance of the amp to meet certain criteria not particularly relevant to normal use). If you plan not to use the product for a long period of time, or if the batteries are completely discharged, remove them from the remote control. His goal is to educate about home theater and develop more standards in the industry to eliminate consumer confusion clouded by industry snake oil.
