For more information see: A/V Receiver Impedance Selector Switch Yamaha A-S801 Dynamic Power Test (1kHz, 4 ohm load, 1CH driven) Reproducing pure, high fidelity sound (PURE DIRECT)When the PURE DIRECT function is on, noise can be reduced by bypassing the circuit that the audio input the signal is not using and stopping the power supply to the circuit.Therefore, in all input sources, you can enjoy music playback in straight and high-quality sound.The indicator above the PURE DIRECT button lights up when this function is turned on.NoteThe BASS, TREBLE, BALANCE and LOUDNESS controls do not function while the PURE DIRECT function is turned on. Reproducing CD sound with the highestsound quality (CD DIRECT AMP) (A-S701 only)When selecting the input source other than CD, if you press the CD DIRECT AMP button, the input source switches to CD. presented with low impedance dips at high frequencies because of potential To make sure the drop-out isnt occurring in the DAC, plug it into another input on the Yamaha. Keep it on 8, leave it there and don't worry about it. Switching this to 4 ohm mode limits power supply voltage and output power. equally efficient systems, the 4 ohm speaker should be 3db higher than the 8 Do not use old and new batteries together. The EIA published a standard which has for many years been the defacto etc. Front Because of liability and the litigious society we live in, we can't tell you to ALWAYS set the impedance switch to the high setting for 4 ohm loads, but we can show you the facts on what this. $799.95 $499.99 37% off msrp Add to cart Item Condition: Yamaha Factory Refurbished Manufacturers Warranty: 1 Year Yamaha + 2 Year Free Extension Included Accessories: CAUTIONDo not change the IMPEDANCE SELECTOR switch while the power is turned on, as doing so may damage the unit.If the IMPEDANCE SELECTOR switch may not befully slid to either position, remove the power cableand slide the switch all the way to either position.Select the switch position according to the impedanceof the speakers.

Leave the setting on 8ohm. Thanks everyone ! Use speaker(s) with proper speaker impedance. But since they dip you need a more robust amp. Do you hear a click inside the amp when it happens? Home Products Audio & Visual Hi-Fi Components A-S701 I just know that I miss the variable loudness knob that most Yamaha's have. Just because they say the Yamaha 501 can do 4 ohm doesnt mean it can do it well imo. Replace the speaker set and press the 6 (power) switch again. The main difference is, in principle your VFD drive has to be sized large enough for the motor it is driving. Impedance dips at low to middle frequencies demand on the amplifier, which can cause it to shut down. Yamaha also has a "pure" CD and all input selector that bypasses all the internal filters if you want to hear exactly what the component signal sounds like. Distinguished Member Aug 1, 2011 #2 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). You must log in or register to reply here. There is no universally adhered-to standard for how consumer loudspeaker Do not drop this product or apply any strong impact to the product. If the power cord plug inserted into the AC outlet is wiggly or loose, do not use that outlet. Nothing comes close. If the problem persists, the cables may be defective.

RIAA equalization curve may be producing a demand for output at 15Hz from the Both are fairly efficient. 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). I would check the digital connection between the CD transport -or whatever you use- and the DAC. You're confusing things a bit. It has relays and protections all over, so I'm somehow confident that it's really hard to blow it away with ease. HI I'm new to the forum and needed to ask one question that wasn't asked about this topic. But they dip into 4 ohms. And how!

IMPEDANCE SELECTOR switch12). Why do you think it will be a benefit? digital media must be proud owners of high order subsonic filters as part of The protection circuitry has been activated due to excessive internal temperature. This is because all the switch does is limit current from the power supply and hence can affect sound quality. My kid is using it daily on TV and XBOX over the SPDIF input, I'm using it couple of times per week as well and it works as expected, as in day one. From my understanding 4 ohm or 8 ohm speakers well go up and down depending on how the frequency (sound) changes in pitch when the signal (music) flows from the speakers. Use the voltage specified for this product. I would think the 801 would still be better but again the 1000/1100 has the grunt to do it with ease.
