Do not expose yourself to high-volume sound for an extended period of time. V = sqrt (6*135) = 28.46 V, that's lower than that required for the 110 W rated output into 8 ohm, yet the power output is higher, using your RX-V1070's specs for this numerical example. Get the Audioholics AV Gear Guide Ebook FREE! If any of the following abnormalities occur, immediately shut down the power. While holding down STRAIGHT on the front panel, press MAIN ZONE z. few ohms to many hundreds of ohms. Pitch is very different to volume. Setting the speaker impedance Under its default settings, the unit is configured for 8-ohm speakers. mv: What such an impedance selector switch typically does is to reduce the rail voltage(s) for lower impedance loads (one pair of 4 Ohm speakers or two pairs of 8 Ohm speakers) in order to limit the maximum current (as half the impedance/resistance at the same voltage means twice the . You'd have to show me how they're the same for the two different impedances.page number in the manual to look at? I'll give it a try. class A/B amplifiers than dips in impedance magnitude at high frequencies, The unit enters standby mode automatically if not operated for 8 hours. The CD DIRECT function or the PURE DIRECT function is turned on. Connected both sets of floor standing speakers. The SPEAKERS selector is not set properly. The result is a pure signal with minimal distortions. Thanks for the advice! So in other words when the volume changes. our music was sold on LP records may have never witnessed this. The IMPEDANCE SELECTOR switch is not set to the correct position. The + and wires are connected in reverse at the amplifier or the speakers. Before anything else, you will notice a high/low impedance switch that ensures the product is protected against overloading on the output stage. They will also operate at DC, but only long enough for the VC to go one direction and jump out of the magnetic gap. You are using an out of date browser. Yet when you look more closely at the curves, they look drastically It would be interesting to hear a bit more on your testing equipment, hookups, and tests. The illustrations used in this Owners Manual are A-S701. Use speaker(s) with proper speaker impedance. If the leaked material comes into contact with your skin or gets into your eyes or mouth, rinse it away immediately and consult a doctor. for manufacturers to use ever lower DC Resistance's (DCR's) on their voice Insert the banana plug into the end of the corresponding terminal. You're confusing things a bit. Press A (power) switch on the front panel to on. This happened to me personally when this If the connections are faulty, no sound will be heard from the speakers, and if the polarity of the speaker connections is incorrect, the sound will be unnatural and lack bass. Hi, first post here, so apologies if some ground rules broken. Batteries that look the same may have different specifications. Thanks for your various tests, they relate to ubiquitous material and are thus very useful to most. 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. Wahoo! 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. The input source indicators light up when the corresponding input sources are selected.The input source names correspond to the names of the connection jacks on the rear panel. Never changing it whether you use 4 ohm or 8 ohm speakers would mean they recommend using the high setting (factory default) with a 4 ohm load, as they state in the full review. Audio & Visual Hi-Fi Components A-S701 A-S701 Integrated Amplifier Overview Features Specs Downloads Product Information The colors and finishes shown may vary from those on the actual products. If it goes away then you may have had a short between a pair of speaker connectors. Turn the component on and start playback. Before cleaning the product, be sure to remove the power cord plug from the AC outlet.

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'? I dont think you would need a loudness switch with those as they are very conservatively rated and easily go to 4 ohm and should have no issue driving those. BALANCE and LOUDNESS controls does not affect the sound. The colors and finishes shown may vary from those on the actual products. If you plan to connect this product to any other devices, first turn off the power to all devices. were utterly confused about how to set the impedance selector switch on their Check that the speaker wires are not touching each other and then turn the power of this unit back on. Expand your listening horizons with the silver A-S701 Integrated Amplifier from Yamaha. 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. equally efficient systems, the 4 ohm speaker should be 3db higher than the 8 ToP-ART (Total Purity Audio Reproduction Technology) and high quality parts. 6 BASS control Increases or decreases the low frequency response. Confirm normal sound output from speakers by increasing the volume gradually. * The contents of this manual apply to the latest specifications as of the publishing date. Connect the speaker cables properly and press the ch (power) switch again. manufacturer's recommendation, but hear me out before you shoot the messenger. manufacturer, they will tell you to ALWAYS set the switch to the low setting Do you hear a click inside the amp when it happens? Do not drop this product or apply any strong impact to the product. The volume level is low while playing a record. Connect the cables properly. There is a problem with the internal circuitries of this unit. The CD DIRECT AMP function is turned off if the following operation is performed. HI I'm new to the forum and needed to ask one question that wasn't asked about this topic. times I've run into threads on our forums or on AVS Forum where users either C'est suffisant pour alimenter dans de bonnes conditions la plupart des enceintes compactes et colonne.

Europe's busiest forums, with independent news and expert reviews, for TVs, Home Cinema, Hi-Fi, Movies, Gaming, Tech and more. 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. The impedance setting of the connected speaker is too small. Left impedance in factory high position. Your email address will not be published. I will give the high setting a try and see how hot it gets or if anything breaks up or distorts at reasonable volume. Locate the Straight? I have no clue what any of this "dipping to 4 ohms" means. I get I will be lowering the impedance to 4ohms. Those of us not old enough to remember when litigious society we live in, I can't tell you to ALWAYS set the impedance enormously, and it is the area on the curve where the magnitude is lowest that Those Energy speakers have a pretty high sensitivity (93 db) which means they don't need a lot of power to play loud. even a modest amount of low frequency energy in the subsonic range can cause Maybe can try both the 801 and the 1200. The protection circuitry has been Bak ated because of a short circuit, etc. 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. Keep the batteries in a location out of reach of children. Impedance dips at low to middle frequencies The SUBWOOFER OUT jack attenuates signals over 90 Hz.9 AUTO POWER STANDBY switch. Front nominal impedance is basically a conservative notion of how low the speakers affiliations include, but are not limited to, the eBay Partner Network, and Before connecting speakers, connect the power cable to an AC wall outlet.
