It runs 800 watts a side into 8 ohms and 1,050 watts a side into 4 ohms, with the same on-board speaker processing as the rest of the series. The black two-unit chassis weighs 7.2 kilograms, so the extra power costs you almost nothing in the rack.\u003c\/p\u003e\u003ch2\u003e800 watts a side into 8 ohms, 1,050 into 4\u003c\/h2\u003e\u003cp\u003eEach channel delivers 800 watts into 8 ohms, 1,050 watts into 4 ohms and 600 watts into 2 ohms, so it will drive two 8-ohm cabinets per side without complaint. The Class-D output is a balanced BTL circuit, total harmonic distortion is 0.1 percent at 10 watts, and frequency response holds within 1 dB across 20 Hz to 20 kHz. Signal-to-noise is 101 dB A-weighted, which keeps the hiss out of quiet passages.\u003c\/p\u003e\u003ch2\u003eD-CONTOUR and the on-board speaker processor\u003c\/h2\u003e\u003cp\u003eD-CONTOUR multi-band dynamic processing on the inputs can be set to FOH\/MAIN, MONITOR or OFF, so the same amp behaves correctly whether it is feeding mains or wedges. The speaker processor section adds a 6-band parametric EQ, a limiter and up to 74 milliseconds of delay, with high-pass and low-pass filters sweeping 20 Hz to 20 kHz and polarity control for lining up a sub. Analogue input to speaker output takes 1.5 milliseconds.\u003c\/p\u003e\u003ch2\u003eSpeaker presets and eight user slots\u003c\/h2\u003e\u003cp\u003eYamaha ships factory presets for its own passive cabinets, covering the CBR, Club and VXS\/VXC series, which means a matched system is a menu choice rather than a measurement session. Eight user presets store your own crossover and limiter settings for different rigs. The over-voltage limiter is user-configurable by wattage or by speaker preset, so a smaller cabinet on the monitor send stays within its limits.\u003c\/p\u003e\u003ch2\u003espeakON, binding posts and quarter-inch outputs\u003c\/h2\u003e\u003cp\u003eOutput connectors are two Neutrik speakON NL4 sockets, two pairs of binding posts and two quarter-inch TS jacks. Inputs accept up to +24 dBu at 20 kilohms balanced or 10 kilohms unbalanced, and gain is selectable between 32 dB, 26 dB, +4 dBu and +14 dBu to suit the console or processor upstream. An input summing function lets you feed one signal to both channels without a Y-cable.\u003c\/p\u003e\u003ch2\u003eProtection, fans and power draw\u003c\/h2\u003e\u003cp\u003eThermal trouble triggers an output limiter first and only shuts the supply down if it persists, while over-voltage and over-current faults cut power immediately and a DC fault stays latched until you clear it. Two 16-step variable-speed fans move air front to rear. Per-channel protect, clip\/limit and signal LEDs sit beside the power, alert and USB indicators, and an auto LED-off setting keeps the rack dark on stage. Power consumption is 60 watts idling and 280 watts at one-eighth power. A 2-metre AC cable and USB cover are included.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;\"\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eYamaha\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;\"\u003eModel\u003c\/th\u003e\n\u003ctd\u003ePX8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;\"\u003eIncluded\u003c\/th\u003e\n\u003ctd\u003eUSB cover, Owner's Manual, Specification sheet, AC cable (2.0m) x 1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;\"\u003eStrings\u003c\/th\u003e\n\u003ctd\u003eOperating Temperature: 0°C to +40°C, Storage temperature: -20°C to +60°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;\"\u003e100V models\u003c\/th\u003e\n\u003ctd\u003e8Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;\"\u003e2Ω\u003c\/th\u003e\n\u003ctd\u003e600W x 2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;\"\u003e120V models\u003c\/th\u003e\n\u003ctd\u003e8Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;\"\u003e220V-240V models\u003c\/th\u003e\n\u003ctd\u003e8Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;\"\u003eTotal harmonic distortion\u003c\/th\u003e\n\u003ctd\u003e0.1% (1kHz, 10W), 0.3% (1kHz, Half power)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;\"\u003eFrequency response\u003c\/th\u003e\n\u003ctd\u003e±1.0dB (1W, 8Ω, 20Hz to 20kHz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;\"\u003eS\/N ratio\u003c\/th\u003e\n\u003ctd\u003e101dB (A-weighted, 8Ω, Gain setting = +14dBu)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;\"\u003eCrosstalk\u003c\/th\u003e\n\u003ctd\u003eLess than -60dB (Half Power, 8Ω, 1kHz, Vol max input 150Ω shunt)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;\"\u003eVoltage Gain\/Sensitivity\u003c\/th\u003e\n\u003ctd\u003e32.0dB\/+9.3dBu (Gain setting: 32dB), 26.0dB\/+15.3dBu (Gain setting: 26dB), 37.3dB\/+4dBu (Gain setting: +4dBu), 27.3dB\/+14dBu (Gain setting: +14dBu)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;\"\u003eMaximum input voltage\u003c\/th\u003e\n\u003ctd\u003e+24dBu\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;\"\u003eInput impedance\u003c\/th\u003e\n\u003ctd\u003e20kΩ (Balance), 10kΩ (Unbalance)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;\"\u003eI\/O Connectors\u003c\/th\u003e\n\u003ctd\u003eNeutrik speakON NL4 x2, Binding post x2 pairs, 1\/4\" PHONE(TS) x2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;\"\u003eIndicators\u003c\/th\u003e\n\u003ctd\u003ePOWER x1 (Green), ALERT x1 (Red), USB x1 (Green), PROTECT x2 (Red), CLIP\/LIMIT x2 (Red), SIGNAL x2 (Green);
