It is in good condition for its age with a few minor blemishes - please see photographs - and will come professionally packaged with manual plus, our usual three month warranty.\u003cbr\u003e\nRotel Say….\u003cbr\u003e\nThis stereo power amplifier was designed to offer lifelike sound and is a natural extension of our love of music. We are famous for our passion for good sound and our love of music.\u003cbr\u003e\nThe power supply is derived from a large, toroidal power transformer. The RB 970BX Mk II has a highly regulated power supply to ensure maximum power capability into difficult speaker loads. This type of design is more expensive to manufacture but it is better for the music. This amplifier will drive 4 ohm speakers very well. Two RB 970BX Mk II amplifiers would be an excellent choice for Bi-amping a set of high performance two way speakers in a stereo system. A third unit, in the Bridged Mono mode, would be an excellent amplifier for an 8 ohm Subwoofer.\u003cbr\u003e\nThis amplifier is capable of tripling its power output if it is operated in the Bridged Mono mode. The minimum speaker impedance for bridged operation is 8 ohms.\u003cbr\u003e\nWe have designed the PCB boards with Symmetrical Circuit Traces. This insures that the precise timing of the music is maintained and faithfully recreated. Circuit traces of different lengths change the timing between the channels slightly. This is unacceptable to us. The PCB transfers the signals as we feel this is more consistent than the sound quality of wire jumpers. The PCB contains metal film resistors and polystyrene or polypropylene capacitors in sonically selected applications. All aspects of this design have been examined with the goal being\u003cbr\u003e\nfaithful reproduction of music.\u003cbr\u003e\nSpecifications:\u003cbr\u003e\nContinuous Power Output: 60 watts\/ch (20 Hz - 20 kHz, ≤ 0.03% THD, 8 ohms}\u003cbr\u003e\nDIN Output: 110 watts\/ch (1 kHz @ 4 ohms, 1% THD)\u003cbr\u003e\nBridged Output (mono): 180 watts (20 Hz - 20 kHz, ≤ 0.03% THD, 8 ohms)\u003cbr\u003e\nTotal Harmonic Distortion: ≤ 0.03% (20 Hz - 20 kHz)\u003cbr\u003e\nIntermodulation Distortion: ≤ 0.02% (60 Hz : 7 kHz, 4:1)\u003cbr\u003e\nFrequency Response: 15 Hz - 100 kHz, ± 1 dB\u003cbr\u003e\nPeak Current Output: 30 Amps (0.1 ohm load, 10 microseconds, 1 pulse)\u003cbr\u003e\nDamping Factor: 280 (20 Hz - 20,000 Hz, 8 ohms)\u003cbr\u003e\nSpeaker Impedance: 4 ohms minimum\u003cbr\u003e\nSignal to Noise Ratio: 116 dB\u003cbr\u003e\nInput Impedance\/Sensitivity: 27 kOhms\/1 volt\u003cbr\u003e\nPower Requirements: 230 Volts, 50 Hz\u003cbr\u003e\nPower Consumption: 300 Watts (Max)\u003cbr\u003e\nDimensions: 440 (W) x 334 (D) x 92 (H) mm\u003cbr\u003e\nWeight: 6.8 kg\u003c\/p\u003e","brand":"2ndhandhifi","offers":[{"title":"Default Title","offer_id":51468543394133,"sku":"536 67978","price":135.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/1094\/5365\/files\/IMG_0805-scaled_cd113941-0164-4e37-8553-a260f04765c9.jpg?v=1758095713","url":"https:\/\/2ndhandhifi.co.uk\/products\/rotel-rb-970bx-mkii-power-amplifier","provider":"2ndhandhifi.co.uk","version":"1.0","type":"link"}
