The equalizer has the same Baxandall-type high and low frequency shelving as the HA1073, with the addition of a high-frequency selector switch. Instead of a fixed 12 kHz frequency, you can choose 4 different frequencies.\u003c\/p\u003e\n\n\u003ch2\u003e73EQJR Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eClass A Line preamplifier\u003c\/li\u003e\n\u003cli\u003eSelectable High Frequency shelving, Baxandall type\u003c\/li\u003e\n\u003cli\u003eSelectable Low Frequency, Baxandall type\u003c\/li\u003e\n\u003cli\u003eMid Frequency, fixed-Q, dual-inductor-based\u003c\/li\u003e\n\u003cli\u003eSelectable midrange center frequencies\u003c\/li\u003e\n\u003cli\u003eClass A single ended with high-headroom output stage\u003c\/li\u003e\n\u003cli\u003eInternal slow-turn-on\u003c\/li\u003e\n\u003cli\u003eCarnhill transformers\u003c\/li\u003e\n\u003cli\u003eRequires compatible 500 Series chassis\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003e73EQJR Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eInput Impedance: 10 kΩ bridging, transformer balanced and floating.\u003c\/li\u003e\n\u003cli\u003eOutput impedance: Less than 75 Ω, transformer balanced and floating, to drive a 600 Ω load.\u003c\/li\u003e\n\u003cli\u003eMaximum output: Greater than +26 dBu into 600 Ω.\u003c\/li\u003e\n\u003cli\u003eTHD: Less than 0.025 % at 1 kHz, less than 0.05 % at 100 Hz.\u003c\/li\u003e\n\u003cli\u003eMaximum gain: 6 dB.\u003c\/li\u003e\n\u003cli\u003ePower consumption: Less than 85 mA per rail at ±16 V DC.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Heritage Audio","offers":[{"title":"Default Title","offer_id":58445324845388,"sku":"42527","price":917.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0769\/9854\/1644\/files\/HeritageAudio73EQJR1.jpg?v=1786984655","url":"https:\/\/noiseroom.lt\/lt\/products\/heritage-audio-73eqjr","provider":"Noise Room","version":"1.0","type":"link"}
