Also, on the amplifier parts and schematic, the above two are about the same with the "older brother" A-S700. where demands for power are relatively small. The optical is for receiving audio from a TV, and the coaxial for receiving audio from a Blu-ray player. amplifiers) than the competition. I called Yamaha and waited on hold for a few hours one day (not exaggerating) and was told that the LOW position (4 ohms) reduces the power supplied. digital media must be proud owners of high order subsonic filters as part of purpose. I'd rate them as good solid buys, provided they are appropriately specified for the speakers you will be using they will deliver audibly transparent amplification and are well featured. It may not display this or other websites correctly. If you can, the easiest solution is to return it. I will be using 2 sets of floorstanding speakers, one JBL and one Athena Technologies.

But since they dip you need a more robust amp. Making it easier to hear the high- and low-frequency ranges even at low volume (LOUDNESS)Enjoy natural sound even at low volume by lowering the mid-range sound level and compensating for the human ears loss of sensitivity to high- and low-frequency ranges at low volume.CAUTIONIf the CD DIRECT AMP function (or the PURE DIRECT function) is turned on with the LOUDNESS control set at a certain level, the input signals bypass the loudness control, resulting in a sudden increase in the sound output level. would represent a purely resistive impedance.

Thanks PSM1, most helpful, sincere apologies for the late acknowledgement. IMHO. Do not expose batteries to high temperatures, such as direct sunlight or an open fire. Turn down the volume, set the LOUDNESS control to the FLAT position, and then adjust the volume again. The A-S501 amp has a very similar design to the 500 amp. Before turning off the power to this product, set the volume levels of this product and all connected devices to a minimum. The INPUT indicators blink and the volume is decreased to the lowest setting automatically, then the INPUT indicators stop flashing and the last input source selected lights up. As a result, specifying a loudspeaker by its DC impedance or voice coil The '801 and 950s should be an awesome combo - enjoy! Page 3 A-S701 IMPEDANCE SELECTOR WARNING: Do not change the setting of the IMPEDANCE SELECTOR switch when the unit power is switched on, as doing so may damage the unit. CD Direct Amp featureStop power supply to the unnecessary circuit for CD playback, convert the input signal to the normal phase and reverse phase and balance transfer to the electronic volume. Depending on the model, there are some countries/regions where it may not be sold. Typically, the magnitude of the loudspeaker impedance can range from a This website uses the TMDb API but is not endorsed or certified by TMDb. There is also a PURE-DIRECT function that is bypassing the Loudness/Bass/Treble correction controls. I would recommend a more powerful Yamaha if u want to stay with Yammie. The A-S1200 offers 90W (into 8 Ohms) and fills space. Power output higher for 6ohm speakers means the rail voltages for it should be higher. (As in high impedance setting). This unit turns off suddenly and the power indicator blinks. Please note that Yamaha cannot accept any liability for any losses resulting from improper use or unauthorized modification of the product.
