{"product_id":"heritage-1073-eq-jr-1414019-used","title":"Heritage 1073 EQ JR #1414019 (Used)","description":"Designed for 500 series rack enclosures, the Heritage Audio 73EQ JR is a full-featured line input module that shares the 3-band equalizer, the transformer-coupled line preamplifier, and the Class A transformer-balanced output stage of the classic 1073 module. This combination allows the module to capture a full transformer-based Class A sound without the need for external preamps. The equalizer section of the module features the same Baxandall-type high and low shelf filters found on the 1073, but with the addition of a high frequency selector switch. You can select four different frequencies of 10, 12, 16 or 20 kHz. The low frequency shelving EQ has a selectable frequency of 35, 60, 110, or 220 Hz. The mid frequency has a dual inductor-based Â±18 dB peaking filter with a fixed Q and selectable center frequencies of 0.36, 0.7, 1.6, 3.2, 4.8, and 7.2 kHz. An EQL button allows for the equalizer section to be turned off and on.The output stage is a Class A singled-ended design driven by a 2N3055 high headroom amplifier. To improve the performance of the module within a 500 series enclosure, the unit utilizes an internal slow turn-on +24V power supply for lower inrush current. The module is finished with Carnhill transformers and Marconi-style knobs for a classic tone and user interface experience.","brand":"Heritage Audio","offers":[{"title":"Default Title","offer_id":44450157953127,"sku":"82783","price":650.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/heritage-1073-eq-jr-1414019-used_82783_1_e6f61934-288b-4f9b-879f-c89a3cde4313.jpg?v=1787091917","url":"https:\/\/vintageking.mom\/products\/heritage-1073-eq-jr-1414019-used","provider":"Vintage King","version":"1.0","type":"link"}
