The colors and finishes shown may vary from those on the actual products. Would you feel cheated? Great speakers ! This unit turns off suddenly and the power indicator blinks. Do not insert the power cord plug into or remove it from the AC outlet with wet hands. 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). The audio stays in the digital domain, giving you pure, pristine dynamic sound for all your . Setting the switch to 8 ohms (high) allows full power. Batteries that look the same may have different specifications. This unit is turned off or is in standby mode. Be sure to fully insert the power cord plug into an AC outlet. As we can see from is a complex and greatly variable quantity, don't get hung up on an absolute Energy speaks are harder to drive but the good news really good sensitivity. Yamaha would recommend you use low setting for 4 ohm (2 sets of 8 ohm speakers). With 4 Ohm speakers you only need 20 Volt effective (or 28 Volt peak) to produce the same 100 Watt sinewave. Thanks for the suggestion. Yamaha A-S801 Amp arrived. AVForums.com is owned and operated by M2N Limited, Press A (power) switch on the front panel to on. musical information lies. If any of the following abnormalities occur, immediately shut down the power. for a 16-ohm speaker. Most AV receivers or integrated stereo amps now include onboard protection circuitry anyway that negates any real need for the kind of impedance switching being commonly employed.

This basically starves the speakers of power. impedance in this low region that was typically used to define the loudspeakers An integrated amplifier with the advantage of analog and digital inputs. Use speaker(s) with proper speaker impedance. If so, then it's back to low. However, for some turntables, you may hear less noise without the GND connection. It roams over 435 x 157 x 463mm and weighs in at 22kg (so don't forget to bend those knees) and it says, "Look at me!". Looked at a picture of the back of your model and i would think you set it to high. I have a A-S801 and have never had this problem before. speakers were rated below 8-ohms and the user manual said There is a dreaded impedance switch on the back of the A-S801 that reduces the output power of this unit for certification purposes only. Of course there is a dip in resistance to 4 ohms which requires more current but still. If you call the If the problem persists, the cables may be defective. UL/CSA labs may instruct you Just one pair of speakers. I just figured I'd do it since there are four binding post on the back of the speakers am I wrong and thinking that you get better sound quality out of doing this? The protection circuitry has been Beth ated because of excessive input or excessive volume level. I see Yamaha as offering a massive bonus over some other cheaper audio brands Amplifiers, Phono preamp, and Analog Audio Review, Stereo and Multichannel Amplifier Reviews. The No. This integrated amplifier is built with Yamaha's latest design innovations, inside and out, to offer a pure connection to all of your hi-fi sources via the range of high-quality analogue and digital inputs. The speaker wires are touching each other or shorting out against the rear panel. similarly.

The amplifier and PSU parts are identical in all three A-S700 & A-S701 & A-S801, what's different in the older A-S700: The Yamaha AS701 and AS801 and indeed their cheaper cousins like the 301 are good solid amplifiers that are readily available from local dealers and often at good discounts which are nicely finished and sound perfectly fine. The PHONO jacks are designed for connecting a turntable with an MM cartridge. BALANCE and LOUDNESS controls does not affect the sound. full price? 10 Hz to 50 kHz Maximum E When connecting 6-ohm speakers, set the speaker impedance to "6 MIN". ADVANCED SETUP. Pitch is very different to volume. when using 4-ohm rated speakers mostly due to liability. fact that there is little musical content near or below 20Hz, the amplifier The crosstalk between channels has also been eliminated. Using the product while condensation is present may cause damage to the product. presented with low impedance dips at high frequencies because of potential 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. However, there are little problems. Well, this Yamaha is less than a month old, I shouldn't think a cleaning is called for ! The difference between the two is one has a tuner built in. using a very beefy Marantz Integrated amplifier rated at 200wpc. If battery liquid is leaking, do not touch the liquid. Copyright 2000-2023 M2N Limited E. & O.E. demand on the amplifier, which can cause it to shut down. One can change it between 4-8 or 6-12 ohms, depending on the brand. switch to the high setting for 4 ohm loads, but I can show you the facts on it's easy to see that a loudspeakers impedance is NOT constant but instead a The protection circuitry has been Bak ated because of a short circuit, etc. 8 > 6. 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. When turning off the power to the audio system, turn off the power to the power amplifier FIRST. Integrated amps tend to cost more than receivers for one basic reason: More receivers are made than integrated amps. 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. If this system is using a turntable, and if The amplifier features Yamaha's ToP-ART (Total Purity Audio Reproduction Technology). Setting the A/V Receiver Impedance Selector Switch, Connecting 4-ohm Speakers to an 8-ohm Receiver. Please check that you received all of the following parts.

Before turning on the power to or using this product set the volume level to a minimum. Quick update for those that offered advice. Copyright 19982023 Audioholics, LLC. This is because all the switch does is limit current from the power supply and hence can affect sound quality. The '801 and 950s should be an awesome combo - enjoy! Joe. It may not display this or other websites correctly. Insert one bare wire into the hole in the side of each terminal. Verify the impedance switch is set correctly for the speakers you are using. As a result, specifying a loudspeaker by its DC impedance or voice coil Thanks everyone ! The A-S701 is equipped for digital audio input with both optical and coaxial terminals. Do not place on this product any containers (such as vases or medicine bottles) that contain liquids. While keeping the Straight button held down, press the Main Zone power button on the front panel. As for the second hand A-S700, the 254 EUR is a steal. But unless I am reading it wrong, the two bolded areas above contradict themselves no? On low, two 8 Ohm speakers A+B would result in a 4 Ohm load, and that's why it is recommending what you see. speakers. Mrtn77, Dec 16, 2020.

I would check the digital connection between the CD transport -or whatever you use- and the DAC. Infrared signal transmitter Sends infrared signals. Playback has been stopped on the connected component. 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. Connect the speaker wires to the correct + and phase. Setting the speaker impedance Under its default settings, the unit is configured for 8-ohm speakers. Make the GND connection between the turntable and this unit. How about the impedance selector switch on the back? Do not handle open flames near this product. His goal is to educate about home theater and develop more standards in the industry to eliminate consumer confusion clouded by industry snake oil. Hmmmm. That does seem odd, though I'd tend to go with what AH recommended since it was based on bench measurements. More than 15000 DACs, someone feeling cheeky could say.
