{"product_id":"heritage-audio-73jr-mkii","title":"Heritage Audio '73JR MKII","description":"\u003cp\u003eReal deal 73 sound.\u003c\/p\u003e\n\n\u003cp\u003eThe 73JR II is an update to the already classic 73JR — a true 73 style mic preamp in a single 500 series slot, with some added features that will satisfy the most demanding of recording engineers.\u003cbr\u003e\nEmploying discrete circuitry and conventional components, the 73JR II is a faithful 3 stage all Class-A 73 preamp. Styroflex and tantalum capacitors have been used throughout. No corners were cut.\u003cbr\u003e\nThe all-discrete Class-A hi-pass filter is sweepable from 20 to 220 Hz — making it easier to make your low end tighter without affecting desired frequencies.\u003cbr\u003e\nThe Line mode allows for reamping of prerecorded tracks, and is a perfect solution for adding some colour to lifeless recordings. The DI input (which automatically switches to DI mode when inserting a ¼” TS cable) is an all-discrete Class-A JFET circuit in front of the microphone transformer — giving you all of the colour and weight you could ask for.\u003cbr\u003e\nFinally, special care has been taken with power handling, implementing internal +24v slow-turn-on-regulation. This is extremely healthy for your 500 series enclosure’s power supply, and keeps the 73JR II’s power independent from other slots.\u003c\/p\u003e\n\n\u003cp\u003eHeritage quality, through and through\u003c\/p\u003e\n\n\u003cp\u003eThere are several compromises usually made when adapting a 73 preamp for the 500 Series, but none that you will find in the 73JR II. The 73JR II uses the full 3 gain stage circuit for up to 80 dB of gain with noise of -125dBu EIN all over the gain positions. The 73JR II uses a true 24volt on board power supply for identical performance and distortion point.\u003c\/p\u003e\n\n\u003cp\u003eThe 73JR II uses only discrete, through hole traditional components and hand labor for that great 70s vibe.\u003cbr\u003e\nThe output transformer is a custom Carnhill, made for in the St Ives factory. The input transformer is a custom Carnhill, made in Carnhill´s Oxford factory — this one has a huge impact on the extra mojo of the unit, and is the same one found in our higher-end 80 Series modules.\u003c\/p\u003e","brand":"Heritage Audio","offers":[{"title":"Default Title","offer_id":57960063140223,"sku":"47733","price":699.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1008\/1216\/1407\/files\/47733-1.jpg?v=1783941568","url":"https:\/\/sxpro.co.uk\/products\/heritage-audio-73jr-mkii","provider":"SX Pro","version":"1.0","type":"link"}
