{"product_id":"presonus-eris-4-5bt-2nd-gen","title":"PreSonus Eris 4.5BT Active Studio Monitors","description":"\u003cp\u003eThe PreSonus Eris 4.5BT is a pair of active media reference monitors that bring studio-quality sound to compact setups. Designed for bedroom studios, video production and high-fidelity gaming, they deliver the accurate, even frequency response that the Eris series is known for worldwide - without the hyped bass or coloured sound typical of consumer desktop speakers.\u003c\/p\u003e\n\u003cp\u003eEach monitor is powered by a 25W Class AB amplifier, with a 4.5-inch woven-composite woofer and a 1-inch ultra-low mass silk-dome tweeter crossing over at 2.8 kHz. The result is a smooth, detailed listen from 70 Hz to 20 kHz, with a peak SPL of 100 dB at one metre - more than enough headroom for critical listening in a home or project studio environment.\u003c\/p\u003e\n\u003ch3\u003eInputs and Connectivity\u003c\/h3\u003e\n\u003cp\u003eThe Eris 4.5BT offers a practical range of connection options. Two balanced quarter-inch TRS inputs and two unbalanced RCA inputs cover the majority of desktop audio interfaces and consumer sources, while a stereo 3.5mm input handles laptops and mobile devices directly. Bluetooth 5.0 adds fast, reliable wireless streaming for casual listening without disconnecting your studio sources. A front-panel volume control and integrated headphone amplifier with 3.5mm output round out the feature set for convenient everyday use.\u003c\/p\u003e\n\u003ch3\u003eAcoustic Tuning and Protection\u003c\/h3\u003e\n\u003cp\u003eHigh and low-frequency acoustic tuning controls - each offering plus or minus 6 dB of adjustment centred at 10 kHz and 100 Hz respectively - allow the monitors to be dialled in to suit the listening environment. A comprehensive protection circuit covers RF interference, output-current limiting, over-temperature, turn-on and turn-off transients and a subsonic filter, while a power saver mode engages automatically after 40 minutes of inactivity.\u003c\/p\u003e\n\u003cp\u003eThe cabinet is built from vinyl-laminated medium-density fibreboard for rigidity and resonance control, keeping the focus on accurate sound reproduction rather than cabinet colouration.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e4.5-inch woven-composite woofer and 1-inch silk-dome tweeter\u003c\/li\u003e\n\u003cli\u003e50W Class AB dual amplification (25W per side)\u003c\/li\u003e\n\u003cli\u003eBluetooth 5.0 wireless input\u003c\/li\u003e\n\u003cli\u003eBalanced quarter-inch TRS, unbalanced RCA and stereo 3.5mm inputs\u003c\/li\u003e\n\u003cli\u003eFront-panel volume control and integrated headphone amplifier\u003c\/li\u003e\n\u003cli\u003eHigh and low-frequency acoustic tuning controls (plus or minus 6 dB)\u003c\/li\u003e\n\u003cli\u003eComprehensive protection circuitry and power saver mode\u003c\/li\u003e\n\u003cli\u003eVinyl-laminated MDF cabinet construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAmplifier power: 50W Class AB (25W per side)\u003c\/li\u003e\n\u003cli\u003eWoofer: 4.5-inch woven composite\u003c\/li\u003e\n\u003cli\u003eTweeter: 1-inch silk-dome\u003c\/li\u003e\n\u003cli\u003eCrossover frequency: 2.8 kHz\u003c\/li\u003e\n\u003cli\u003eFrequency response: 70 Hz to 20 kHz\u003c\/li\u003e\n\u003cli\u003ePeak SPL: 100 dB at 1 metre\u003c\/li\u003e\n\u003cli\u003eInputs: Bluetooth 5.0, 2 x balanced quarter-inch TRS, 2 x unbalanced RCA, 1 x stereo 3.5mm\u003c\/li\u003e\n\u003cli\u003eInput impedance: 10 kΩ\u003c\/li\u003e\n\u003cli\u003eAudio controls: High frequency plus or minus 6 dB at 10 kHz, low frequency plus or minus 6 dB at 100 Hz\u003c\/li\u003e\n\u003cli\u003eCabinet material: Vinyl-laminated MDF\u003c\/li\u003e\n\u003cli\u003eVoltage: 220-240V\u003c\/li\u003e\n\u003cli\u003eIncludes: Speaker wire, 3.5mm TRS to stereo RCA cable and stereo 3.5mm TRS to 3.5mm TRS cable\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Presonus","offers":[{"title":"Default Title","offer_id":57482587570563,"sku":"2777504123","price":179.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0557\/0556\/7432\/files\/0035_2777504123_pre_mon_frt_1_nr.jpg?v=1772539601","url":"https:\/\/www.normans.co.uk\/products\/presonus-eris-4-5bt-2nd-gen","provider":"Normans Musical Instruments","version":"1.0","type":"link"}
