As an homage to these legendary products, we packed this technology in a 500-series module. The PHOTON 500 uses an opto-coupler, which introduces negative feedback in the audio path, taking care of gain reduction, being the basics of all compression. The PHOTON 500 has an electronically balanced input with 2520 compatible op-amp in the gain stage. The output is balanced by a Carnhill transformer.\u003c\/p\u003e  \u003ch3\u003eSpecifications:\u003c\/h3\u003e  \u003cul\u003e \u003cli\u003eOptical Compressor\u003c\/li\u003e \u003cli\u003eAll stepped manipulators\u003c\/li\u003e \u003cli\u003eSidechain HPF: OFF, 60Hz, 120Hz\u003c\/li\u003e \u003cli\u003eInput Impedance (balanced): 10k ohm\u003c\/li\u003e \u003cli\u003eOutput Impedance (balanced): 600 ohm\u003c\/li\u003e \u003cli\u003eAudio transformers: Carnhill\u003c\/li\u003e \u003cli\u003eOperating level: +4 dBu\u003c\/li\u003e \u003cli\u003eMax input level: +20 dBu\u003c\/li\u003e \u003cli\u003eMax output level: +22 dBu\u003c\/li\u003e \u003cli\u003eNoise level: -99 dBA\u003c\/li\u003e \u003cli\u003eMax gain: 30 dB\u003c\/li\u003e \u003cli\u003eMax gain reduction: 20 dB\u003c\/li\u003e \u003cli\u003eRatio: 2:1, 4:1, 12:1\u003c\/li\u003e \u003cli\u003eFrequency response: 8Hz - 20kHz, +\/- 0.1dB\u003c\/li\u003e \u003cli\u003eTHD+N: 0.012%\u003c\/li\u003e \u003cli\u003ePower consumption: 2.5W\u003c\/li\u003e \u003c\/ul\u003e","brand":"IGS Audio","offers":[{"title":"Default Title","offer_id":44449851703399,"sku":"55832","price":860.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/igs-photon-2024_55832_1_84827820-5dac-4344-a8a1-99aeda298df8.jpg?v=1787090694","url":"https:\/\/vintageking.mom\/products\/igs-audio-photon-500-opto-compressor","provider":"Vintage King","version":"1.0","type":"link"}
