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.
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. PX10/PX8/PX5/PX3 Reference Manual...
The input signal is divided into separate frequency ranges for driving a two-way full-range speaker in bi-amp mode. Channel A + Channel B Use for driving a subwoofer with a stereo signal Stereo input signals drive a subwoofer in Power Boost mode (PX5 and PX3 only) (PX5) PX10/PX8/PX5/PX3 Reference Manual...
A full-range speaker and a subwoofer A full-range speaker driven in bi-amp mode Full-range speaker Power Boost mode Subwoofer NOTE In Power Boost mode, the two-channel amplifiers are used as one-channel, high-power amplifier (PX5 and PX3 only). PX10/PX8/PX5/PX3 Reference Manual...
Maximum power is constant if the volume is lowered. For example, if the amplifier gain on the PX10 is set to 32 dB, the input sensitivity is +9.3 dBu and the maximum output power is 1,000 W (if speaker impedance is 8Ω). When the volume is not lowered (0 dB), output power of 1,000 W results with +9.3 dBu input.
