This no-compromise, 2U powerhouse is our premier solution for virtually any touring or installed sound system. A rear panel switch selects 2Ω or 4Ω operation, and bridging the amp delivers up to 3600 watts of pure, clean power into 4Ω or 8Ω loads. The AP4K features a meticulously optimized signal path, with a toroidal transformer to reduce hum and interference. The 3-tier Class H design approaches the efficiency of Class D amplifiers while maintaining the superior transient response and low distortion of the best analog designs. With transparent limiting, advanced protection, all-steel construction, and exceptional sound quality, the AP4K is designed to excel in the most demanding conditions and power exceptional performances.\u003c\/p\u003e\u003ch4\u003eFeatures\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-Channel Class H Design\u003c\/li\u003e\n\u003cli\u003e1800 W per Channel @ 2Ω or 4Ω\u003c\/li\u003e\n\u003cli\u003e3600 W Bridged @ 4Ω or 8Ω\u003c\/li\u003e\n\u003cli\u003eBalanced XLR and 1\/4\" Inputs\u003c\/li\u003e\n\u003cli\u003eBinding Post and speakON® Outputs\u003c\/li\u003e\n\u003cli\u003eShort Circuit, DC, and Thermal Protection\u003c\/li\u003e\n\u003cli\u003eSoft Turn-On Circuit to Protect Speakers\u003c\/li\u003e\n\u003cli\u003eAll-Steel Construction\u003c\/li\u003e\n\u003cli\u003eMade in Canada\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAmplifier class Class H\u003c\/li\u003e\n\u003cli\u003eContinuous Average Power AT 8 Ohms (Watts) 1000 W x2 (4Ω), 600 W x2 (2Ω)\u003c\/li\u003e\n\u003cli\u003eContinuous Average Power AT 4 Ohms (Watts) 1800 W x2 (4Ω),1000 W x2 (2Ω)\u003c\/li\u003e\n\u003cli\u003eContinuous Average Power AT 2 Ohm (Watts) 1800 W x2 (2Ω)\u003c\/li\u003e\n\u003cli\u003eContinuous Average Power Bridged (Watts) 3600 W (8Ω, 4Ω)\u003c\/li\u003e\n\u003cli\u003eBurst Average Power AT 8 Ohms (Watts) 1800 W x2 (4Ω), 1000W x2 (2Ω)\u003c\/li\u003e\n\u003cli\u003eBurst Average Power AT 4 Ohms (Watts) 3500 W x2 (4Ω), 1800 W x2 (2Ω)\u003c\/li\u003e\n\u003cli\u003eBurst Average Power AT 2 Ohms (Watts) 2500 W x2 (2Ω)\u003c\/li\u003e\n\u003cli\u003eBurst Average Power Bridged (Watts) 7000 W (8Ω), 5000 W (4Ω)\u003c\/li\u003e\n\u003cli\u003eFrequency Response (Hz CM +\/- 1dB) 20 Hz - 20 kHz\u003c\/li\u003e\n\u003cli\u003eHum and Noise (un \/ Aweighted -dB) -100 dB Unweighted, -115 dB A-Weighted\u003c\/li\u003e\n\u003cli\u003eTHD -1kHz- 4 OHMS \u0026lt;0.1%\u003c\/li\u003e\n\u003cli\u003eTHD - 20Hz-20kHz CM 4 Ohms \u0026lt;0.1%\u003c\/li\u003e\n\u003cli\u003eSlew Rate (V\/uS) 25 V\/uS Average, 50 V\/uS Bridged\u003c\/li\u003e\n\u003cli\u003eDamping Factor (30 Hz - 400 Hz AT 8 Ohms) 600\u003c\/li\u003e\n\u003cli\u003eCrosstalk (1kHz \/ 20Hz-20kHz) -75 \/ -60 dB\u003c\/li\u003e\n\u003cli\u003eInput Impedance - Bal\/Unbal (Ohms) 10 kΩ \/ 5 kΩ\u003c\/li\u003e\n\u003cli\u003eInput Sensitivity (Vrms) For Full Power Out 1.0 V (2Ω) \/ 1.4 V (4Ω)\u003c\/li\u003e\n\u003cli\u003eMax Voltage Gain (dB) 36 dB\u003c\/li\u003e\n\u003cli\u003eCMRR AT 60Hz (min\/typ) 48 dB \/ 56 dB\u003c\/li\u003e\n\u003cli\u003eStereo \/ Bridge (S\/B) Yes\u003c\/li\u003e\n\u003cli\u003eProtection DC, Load, Thermal\u003c\/li\u003e\n\u003cli\u003eLimiter Peak (Defeatable)\u003c\/li\u003e\n\u003cli\u003eHigh Pass Filter 18 dB per Octave at 50 Hz\u003c\/li\u003e\n\u003cli\u003eCooling Fan\u003c\/li\u003e\n\u003cli\u003eCooling Path Front to Rear\u003c\/li\u003e\n\u003cli\u003eInputs - XLR 2\u003c\/li\u003e\n\u003cli\u003eInputs - 1\/4 IN Jacks 4\u003c\/li\u003e\n\u003cli\u003eOutputs - Speakon 4-pin 2\u003c\/li\u003e\n\u003cli\u003eOutputs - Binding Post 2\u003c\/li\u003e\n\u003cli\u003ePower Consumption (typ\/max) 1130 W \/ 1800 W\u003c\/li\u003e\n\u003cli\u003eRack Spaces 2\u003c\/li\u003e\n\u003cli\u003eTransformer Type Toroidal\u003c\/li\u003e\n\u003cli\u003eExterior Finish Black Paint\u003c\/li\u003e\n\u003cli\u003eDimensions (DWH \/D fm ears inches) 16.5\" x 19\" x 3.5\" (41.5 cm x 48.3 cm x 8.9 cm)\u003c\/li\u003e\n\u003cli\u003eWeight (lbs \/ kg) 41 lbs \/ 18.5 kg\u003c\/li\u003e\n\u003cli\u003eModel: AP4K\u003c\/li\u003e\n\u003cli\u003eUPC: 840402033790\u003c\/li\u003e\n\u003cli\u003eShipping dimensions: 25 x 22 x 10 in\u003c\/li\u003e\n\u003cli\u003eShipping weight: 55 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAvailable now at ProDJ.\u003c\/p\u003e","brand":"Yorkville","offers":[{"title":"Default Title","offer_id":50862784381125,"sku":"AP4K","price":2175.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.prodj.com\/products\/yorkville-ap4k-2-channel-1800w-power-amplifier","provider":"ProDJ","version":"1.0","type":"link"}
