Compression is handled by BF245A FET transistors in a matched quad arrangement; both gain stages use discrete IGS 2520 op-amps; UTM Industry transformers are fitted on input and output. Attack range of 20 µs to 1.2 ms and release from 50 ms to 1.2 s match the 1176 topology. All controls run on 24-position Elma switches.\u003c\/p\u003e\n\n  \u003ch3\u003eBF245A FET and 1176 Topology — Fast Compression in Stereo\u003c\/h3\u003e\n  \u003cp\u003eA FET as the gain reduction element defines the 1176 character: near-instantaneous response to transients (attack from 20 µs), wide ratio range, and a tonal character described as punchy, aggressive, and sticky at low attack and short release settings. The Volf implements this topology across two channels with a link option for stereo bus compression with coherent imaging. The IC\/UTM Industry transformer input switch selects between a cleaner IC input (less transformer coloration) and the warm, dense character of the transformer path — the difference is most audible at aggressive gain reduction settings. AMP mode bypasses the compression circuit and routes signal through the amplifier stage at 45 dB gain — FET and transformer character without any dynamics control.\u003c\/p\u003e\n\n  \u003ch3\u003eSidechain HPF, Wet\/Dry and All Buttons Mode\u003c\/h3\u003e\n  \u003cp\u003eThe sidechain HPF (60\/90\/120\/180\/240 Hz or Off) decouples low-frequency content from the compression control — essential on bass and mix bus material with heavy kick drum content, where without HPF the compressor pumps rhythmically in time with the low end. The 24-position Elma Wet\/Dry control implements parallel compression inline without external routing or a mix bus. Ratio options include standard 1176 values (4:1, 8:1, 12:1, 20:1) and the All Buttons mode, in which all ratio buttons are engaged simultaneously, producing the aggressive over-compression associated with recordings by Led Zeppelin, Nirvana, and countless others. Maximum gain reduction is 30 dB, maximum gain 45 dB, bandwidth 8 Hz to 22 kHz at ±0.2 dB.\u003c\/p\u003e\n\n  \u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eDual-channel stereo Class A FET compressor — inspired by UREI 1176\u003c\/li\u003e\n    \u003cli\u003eCompression element: BF245A FET, matched quad\u003c\/li\u003e\n    \u003cli\u003eDiscrete IGS 2520 op-amps in both gain stages\u003c\/li\u003e\n    \u003cli\u003eSwitchable input: UTM Industry transformers or IC-balanced\u003c\/li\u003e\n    \u003cli\u003eUTM Industry output transformers\u003c\/li\u003e\n    \u003cli\u003eAttack: 20 µs – 1.2 ms (stepped, Elma switch)\u003c\/li\u003e\n    \u003cli\u003eRelease: 50 ms – 1.2 s (stepped, Elma switch)\u003c\/li\u003e\n    \u003cli\u003eRatio: 4:1, 8:1, 12:1, 20:1 + All Buttons mode\u003c\/li\u003e\n    \u003cli\u003eMax gain: 45 dB; max gain reduction: 30 dB\u003c\/li\u003e\n    \u003cli\u003eAMP mode: bypass compression, signal through amplifier at 45 dB\u003c\/li\u003e\n    \u003cli\u003eSidechain HPF: 60 \/ 90 \/ 120 \/ 180 \/ 240 Hz \/ Off (stepped)\u003c\/li\u003e\n    \u003cli\u003eWet\/Dry Mixer — 24-position Elma (inline parallel compression)\u003c\/li\u003e\n    \u003cli\u003eStereo Link: yes\u003c\/li\u003e\n    \u003cli\u003eAll controls stepped — 24-position Elma switches throughout\u003c\/li\u003e\n    \u003cli\u003eInput impedance: 10 kΩ (IC) \/ UTM Industry transformers (switchable)\u003c\/li\u003e\n    \u003cli\u003eOutput impedance: 600 Ω (UTM Industry transformers)\u003c\/li\u003e\n    \u003cli\u003eMax input and output: +18 dBu; operating level: +4 dBu\u003c\/li\u003e\n    \u003cli\u003eInternal linear power supply, 20 W; made in Poland\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eType: dual-channel stereo Class A FET compressor\u003c\/li\u003e\n    \u003cli\u003eCompression element: BF245A FET, matched quad\u003c\/li\u003e\n    \u003cli\u003eInput impedance: 10 kΩ (IC\/UTM Industry transformer, switchable)\u003c\/li\u003e\n    \u003cli\u003eOutput impedance: 600 Ω (UTM Industry transformers)\u003c\/li\u003e\n    \u003cli\u003eOperating level: +4 dBu\u003c\/li\u003e\n    \u003cli\u003eMax input level: +18 dBu\u003c\/li\u003e\n    \u003cli\u003eMax output level: +18 dBu\u003c\/li\u003e\n    \u003cli\u003eMax gain: 45 dB\u003c\/li\u003e\n    \u003cli\u003eMax gain reduction: 30 dB\u003c\/li\u003e\n    \u003cli\u003eNoise level: 110 dB(A)\u003c\/li\u003e\n    \u003cli\u003eAttack: 20 µs – 1.2 ms\u003c\/li\u003e\n    \u003cli\u003eRelease: 50 ms – 1.2 s\u003c\/li\u003e\n    \u003cli\u003eFrequency response: 8 Hz – 22 kHz, ±0.2 dB\u003c\/li\u003e\n    \u003cli\u003eSNR: \u0026gt;84 dB\u003c\/li\u003e\n    \u003cli\u003eTHD: 0.12%\u003c\/li\u003e\n    \u003cli\u003eTHD+N: 0.19%\u003c\/li\u003e\n    \u003cli\u003eCrosstalk: 80 dB\u003c\/li\u003e\n    \u003cli\u003eSidechain HPF: 60 \/ 90 \/ 120 \/ 180 \/ 240 Hz \/ Off\u003c\/li\u003e\n    \u003cli\u003ePower: internal linear PSU, 20 W\u003c\/li\u003e\n    \u003cli\u003eMade in: Poland\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e","brand":"IGS Audio","offers":[{"title":"Default Title","offer_id":54001624940881,"sku":"58957","price":2481.29,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/IGSAudioVolf.jpg?v=1781115395","url":"https:\/\/wrdtunes.com\/fr\/products\/igs-audio-volf","provider":"Wired Tunes","version":"1.0","type":"link"}
