It not only shares the 3-band equalizer of its big brother, the Heritage Audio 1073, but also shares the same transformer coupled line preamp  and Class A transformer balanced output stage.\u003c\/p\u003e  \u003cp\u003eThis makes the 73EQJR unique on its class, being able to capture a full transformer based, Class A sound without relying on external preamps. The EQ features the same Baxandall type High and Low shelf found in the HA1073, with the addition of a high frequency selector switch. 4 different frequencies are possible instead of the fixed 12 kHz one.\u003c\/p\u003e  \u003cp\u003eThe mid band is the same exact dual inductor one, thick low and sweet high midrange boosts without becoming muddy or brittle. The line preamp has a range of +6 to -20 dB, allowing heavy EQ boosts without overloading A\/D converters.\u003c\/p\u003e  \u003cp\u003eFinally, special care has been taken with power handling, implementing internal +24 V slow turn on regulation (about 20 seconds to reach full voltage). This makes your 73EQJR independent of the rest of the slots and makes your lunchbox's PSU happier.\u003c\/p\u003e  \u003ch3\u003eSpecifications:\u003c\/h3\u003e  \u003cul\u003e \u003cli\u003eInput Impedance: 10 kOhms bridging, transformer balanced and floating\u003c\/li\u003e \u003cli\u003eOutput impedance: Less than 75 Ohms, transformer balanced and floating, to drive a 600 ohms load\u003c\/li\u003e \u003cli\u003eMaximum output: Greater than +26 dBu into 600 Ohms\u003c\/li\u003e \u003cli\u003eTHD: Less than 0.025% at 1 kHz, less than 0.05% at 100 Hz\u003c\/li\u003e \u003cli\u003eMaximum gain: 6 dB\u003c\/li\u003e \u003cli\u003ePower consumption: Less than 85 mA per rail at ±16 VDC\u003c\/li\u003e \u003c\/ul\u003e","brand":"Heritage Audio","offers":[{"title":"Default Title","offer_id":44450300100711,"sku":"103904","price":1099.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/heritage-audio-73eqjr_103904_1_cb860a78-d6f8-449e-abcd-77064f19ca91.jpg?v=1787092512","url":"https:\/\/vintageking.com\/products\/heritage-audio-73eqjr","provider":"Vintage King","version":"1.0","type":"link"}
