At its core are 4 NOS 6BA6 military-grade tubes and 6 custom-designed transformers, which together recreate the classic \"magic\" saturation and glue the original was famous for. The \"Next Gen\" version retains this sonic signature while introducing key improvements for modern studios, such as significantly lower self-noise (-78 dBu) and a more accessible price point, all while maintaining hand-built production in Madrid.\u003c\/p\u003e\n\u003cp\u003eCompared to the original, the Model 670N offers significantly greater flexibility. It features a new \u003cem\u003eOutput Gain Make-up\u003c\/em\u003e stage based on the transformer-coupled HA-880 op-amp, allowing for clean signal boost without losing the character of tube compression. Modern features have also been added, such as an advanced Sidechain filter (to prevent low frequencies from triggering compression), independent Bypass for each channel, and M\/S (LAT\/VERT) operation modes. The \u003cem\u003eDC Threshold\u003c\/em\u003e (Progressive Knee) parameter has been brought to the front panel, enabling a smooth transition from hard limiting to transparent compression, offering unprecedented dynamic control.\u003c\/p\u003e\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFaithful recreation of Vari-MU topology with 4 NOS 6BA6 tubes and 6 transformers\u003c\/li\u003e\n\u003cli\u003eOperating modes: Dual Mono, Stereo Link, Mid\/Side (LAT\/VERT)\u003c\/li\u003e\n\u003cli\u003e6 Attack\/Release times optimized for modern production\u003c\/li\u003e\n\u003cli\u003eProgressive DC Threshold (knee control) accessible on the front panel\u003c\/li\u003e\n\u003cli\u003eAdvanced Sidechain High-Pass Filter\u003c\/li\u003e\n\u003cli\u003eOutput gain stage based on HA-880 transformer op-amp\u003c\/li\u003e\n\u003cli\u003eUltra-low noise and distortion (THD \u0026lt; 0.5%)\u003c\/li\u003e\n\u003cli\u003eHand-built in Spain\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: Stereo Vari-MU Tube Compressor\u003c\/li\u003e\n\u003cli\u003eTubes: 4x NOS 6BA6\u003c\/li\u003e\n\u003cli\u003eTransformers: 6x Custom Heritage Audio\u003c\/li\u003e\n\u003cli\u003eFrequency Response: 20 Hz - 20 kHz (± 0.5 dB)\u003c\/li\u003e\n\u003cli\u003eInput Impedance: 15 kΩ\u003c\/li\u003e\n\u003cli\u003eMax Output Level: +29 dBu\u003c\/li\u003e\n\u003cli\u003eFormat: 19\" Rack, 5U height\u003c\/li\u003e\n\u003cli\u003eWeight: 5.8 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Heritage Audio","offers":[{"title":"Default Title","offer_id":52923680588113,"sku":"58556","price":2948.65,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/HeritageAudioTheHERCHILDNextGenModel670N1.jpg?v=1769683249","url":"https:\/\/wrdtunes.com\/products\/heritage-audio-the-herchild-next-gen-model-670n","provider":"Wired Tunes","version":"1.0","type":"link"}
