If adjusting the BASS, TREBLE, BALANCE, and LOUDNESS controls doesn't change the sound on your Yamaha Receiver, it's likely that the CD DIRECT AMP (R-S700 only) or the PURE DIRECT switch is turned on. The CD DIRECT AMP or the PURE DIRECT switch must be turned off to use those controls.
How to stop crackling and hissing noises on Yamaha R-S700?
To address continuous crackling and hissing noises with your Yamaha Receiver, consider that the noises may result from lightning, fluorescent lamps, motors, thermostats or other electrical equipment. Try using an outdoor antenna and a earth ground. This will help somewhat, but it is difficult to eliminate all noise.
Why is the sound level low on my Yamaha Receiver?
If the sound level is low on your Yamaha Receiver, it could be due to the loudness control function operating. Try turning down the volume, setting the LOUDNESS control to the FLAT position, and then adjusting the volume again.
What to do if Yamaha R-S700 cannot tune in station automatically?
If your Yamaha Receiver is unable to tune into a desired station using the automatic tuning method: * Tighten the AM loop antenna connections and orient it for the best reception, as the signal may be weak or the antenna connections may be loose. * Try using the manual tuning method.
Why is my Yamaha R-S700 Receiver lacking bass and ambience?
If your Yamaha Receiver sounds like it's lacking bass and ambience, check that the + and – wires are connected in reverse at the amplifier or the speakers and connect the speaker wires to the correct + and – phase.
How to eliminate humming sound from Yamaha R-S700 Receiver?
To address a humming sound coming from your Yamaha Receiver, try the following: * Ensure the audio plugs are firmly connected; if the problem continues, the cables may be defective. * If using a turntable, make the GND connection between the turntable and the unit.
How to improve noisy FM stereo reception on Yamaha R-S700?
If you're experiencing noisy FM stereo reception on your Yamaha Receiver, consider the following: * Check the antenna connections and try using a high-quality directional FM antenna, as the issue may be due to the characteristics of the FM stereo broadcasts or a poor antenna input. * Switch to monaural mode.
Why can I only hear sound from one speaker on my Yamaha R-S700?
If you're only hearing sound from one speaker connected to your Yamaha Receiver, the issue might be: * Incorrect cable connections. Connect the cables properly, and if the problem persists, the cables may be defective. * Incorrect setting for the BALANCE control. Set the BALANCE control to the appropriate position.
What to do if the sound suddenly goes off on a Yamaha R-S700?
If the sound on your Yamaha Receiver suddenly goes off, here's what you can check: * The protection circuitry may have been activated due to a short circuit. Ensure the IMPEDANCE SELECTOR switch is in the correct position. * Make sure the speaker wires are not touching each other and then turn the power of this unit back on. * The unit may have become too hot; ensure the openings on the top panel are not blocked. * The automatic power down function might have turned the unit off. Change the automatic power down setting (“APD TIMER” in the Advanced Setup menu) to a longer setting, or disable the automatic power down function by setting the POWER MANAGEMENT switch on the rear panel to OFF.
How to fix a Yamaha R-S700 that fails to turn on?
If your Yamaha receiver isn't turning on, consider these possible causes and solutions: 1. Ensure the power cable is firmly connected to both the receiver and the power outlet. 2. Verify the impedance setting matches your speakers. 3. Check for short circuits in the speaker wires; ensure they are not touching each other. Then, turn the receiver back on. 4. Confirm the IMPEDANCE SELECTOR switch on the rear panel is set to either end, with the power off during adjustment. 5. If the unit experienced a strong electrical shock, turn it off, unplug it for 30 seconds, then plug it back in and try again.
