Introduction Thank you for your purchase of the Yamaha PX10, PX8, PX5 or PX3 power amplifier. Please read through this manual carefully before using for the first time, in order to take full advantage of your PX power amplifier’s superlative features and enjoy trouble-free operation for years to come. • Please read the Precautions in the PX10/PX8/PX5/PX3 Owner’s Manual before use. • The illustrations as shown in this manual are for instructional purposes only.
Introduction — Usage examples Usage examples PX amplifiers can be used for various applications. Use with two full-range speakers This conventional application inputs stereo L/R signals to each channel (A/B) for stereo reproduction with two speakers. Use with a full-range speaker and subwoofer The input signal is divided into separate frequency ranges for driving a full-range speaker and subwoofer.
Introduction — Usage examples Use with a full-range speaker driven in bi-amp mode The input signal is divided into separate frequency ranges for driving a two-way full-range speaker in bi-amp mode.
Introduction — Usage examples PX amplifier available system configurations PX amplifier can be used with the following 15 types of system configurations, including the examples above. Input configuration (routing) Dual mode Parallel mode Single mode Sum mode Channel A and channel B are independent. After dividing channel A input signal to channel A and channel B, the signal is processed. After processing channel A input signal, the signal is divided to A and channel B.
Introduction — Usage examples Signal processing in PX amplifier The PX amplifier gives you comprehensive control over the sound with input processors and speaker processors. The signals from the input connectors are processed in input processors equipped in each input connectors. The processed signals are added or divided depending on the set routing, processed finally with the speaker processor in each channel, and output from the [SPEAKERS] terminals.

Reference — Troubleshooting Troubleshooting Symptom Possible causes Possible solution For the protection of the display, the display automatically turns off if the PX amplifier has not been operated for 20 minutes. Press any key on the front panel or rotate the main knob to turn on the display again. If the Black-out mode is on, the back light of the display automatically turns off when PX amplifier has not been operated for around 10 seconds.
Reference — Troubleshooting Symptom No sound from speakers. The panel controls cannot be operated. Possible causes Possible solution Cables are not connected appropriately. If the meter does not rise even if raising the volume knob, there may be problems in connectivity at the input side. If the meter rises, there may problems at the output side. Connect to input jacks and output terminals appropriately. At the output side, make sure that terminals outputting signals are connected.
