This 4-channel Class AB amplifier produces 60W RMS x 4 at 4Ω or can be bridged to deliver 190W RMS x 2 at 4Ω for component speakers or subwoofer applications. The versatile design allows operation in 4-channel, 3-channel, or 2-channel modes, making it perfect for powering complete systems from front and rear speakers to dedicated subwoofer configurations.\u003c\/p\u003e\n\n\u003cp\u003eThe automatic signal sensing technology automatically selects between RCA or speaker-level inputs and powers on in sync with your receiver. Variable high-pass filter (40Hz-500Hz) and low-pass filter provide precise frequency control on both channel sets. The adjustable bass boost feature offers 0\/6\/12dB of enhancement at 50Hz for optimal low-frequency impact. With high-volt input level control accommodating up to 6.5V (RCA) or 26V (speaker level), large toroidal transformer for stable power supply, and comprehensive protection circuitry, the GM-A6704 delivers clean, powerful, distortion-free performance.\u003c\/p\u003e\n\n\u003cp\u003e✔ Key Features \u0026amp; Benefits\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e✔ \u003cstrong\u003eClass AB Design:\u003c\/strong\u003e Balanced efficiency and performance with minimized crossover distortion for high-quality sound reproduction\u003c\/li\u003e\n\u003cli\u003e✔ \u003cstrong\u003eVariable Bass Boost:\u003c\/strong\u003e Adjustable bass enhancement from 0 to 12dB at 50Hz in three levels (0\/6\/12dB) for customized low-frequency impact\u003c\/li\u003e\n\u003cli\u003e✔ \u003cstrong\u003eVariable HPF\/LPF:\u003c\/strong\u003e Adjustable high-pass and low-pass filters from 40Hz to 500Hz for precise frequency control and system optimization\u003c\/li\u003e\n\u003cli\u003e✔ \u003cstrong\u003eMultiple Configuration Modes:\u003c\/strong\u003e Operate in 4-channel, 3-channel, or 2-channel modes for flexible system building\u003c\/li\u003e\n\u003cli\u003e✔ \u003cstrong\u003eBridgeable Configuration:\u003c\/strong\u003e Combine channels for 190W RMS x 2 at 4Ω for component speakers or subwoofer applications\u003c\/li\u003e\n\u003cli\u003e✔ \u003cstrong\u003eAutomatic Signal Sensing:\u003c\/strong\u003e Automatically detects RCA or speaker-level inputs and powers on with receiver\u003c\/li\u003e\n\u003cli\u003e✔ \u003cstrong\u003eLarge Toroidal Transformer:\u003c\/strong\u003e High-quality power supply with high-speed switching MOSFET for stable, consistent performance\u003c\/li\u003e\n\u003cli\u003e✔ \u003cstrong\u003eComprehensive Protection:\u003c\/strong\u003e Thermal, short circuit, and overload protection with gain control caution feature\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eTechnical Specifications\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass:\u003c\/strong\u003e Class AB Amplifier\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChannels:\u003c\/strong\u003e 4-Channel (Bridgeable to 2-Channel)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Power:\u003c\/strong\u003e 1000W Total (170W x 4 at 4Ω, 250W x 4 at 2Ω)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRMS Power (CEA-2006):\u003c\/strong\u003e 60W x 4 at 4Ω (14.4V)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRMS Power:\u003c\/strong\u003e 95W x 4 at 2Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridged Power:\u003c\/strong\u003e 190W x 2 at 4Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Power:\u003c\/strong\u003e 60W x 4 (50Hz-15kHz, 5% THD, all channels driven)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad Impedance:\u003c\/strong\u003e 2Ω to 8Ω (2Ω minimum for bridged mode: 4Ω)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 10Hz - 70kHz (+0dB, -3dB)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal-to-Noise Ratio:\u003c\/strong\u003e 95dB (IEC-A Network)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistortion:\u003c\/strong\u003e 0.05% (10W, 1kHz)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Sensitivity:\u003c\/strong\u003e 0.3V - 6.5V (RCA), 3.0V - 26V (Speaker Level)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable HPF\/LPF:\u003c\/strong\u003e 40Hz-500Hz, 12dB\/Octave Slope\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFixed LPF:\u003c\/strong\u003e 80Hz, 12dB\/Octave Slope\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBass Boost:\u003c\/strong\u003e 0\/6\/12dB at 50Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e 4 x RCA, Speaker-Level with Auto-Sensing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutputs:\u003c\/strong\u003e Screw-Type Speaker Terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse:\u003c\/strong\u003e 25A x 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply:\u003c\/strong\u003e 14.4V DC (10.8V - 15.1V allowable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Consumption:\u003c\/strong\u003e 31A Maximum\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PIONEER","offers":[{"title":"Frankies Auto Electrics","offer_id":40427170037961,"sku":"10039818","price":229.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0024\/9803\/5810\/files\/b61110c2e58c4f1da4df20301b9288cf.jpg?v=1768341117","url":"https:\/\/www.jbhifi.com.au\/products\/pioneer-gma6704-1000w-4-channel-bridgeable-class-ab-car-amplifier-with-variable-bass-boost","provider":"JB Hi-Fi","version":"1.0","type":"link"}
