Inductor Equalizer\u003c\/strong\u003e\n\n\u003cp\u003eThe iQ. Inductor Equalizer is a dual-mono parametric equalizer with inductors in the filter circuits, housed in a rackmount unit with an internal power supply, designed by IGS Audio for recording, mixing, and mastering duties. Four bands – SUB, BASS, MID, and HIGH – cover 28 Hz to 25 kHz with overlapping frequency ranges, allowing two bands to operate simultaneously in the same frequency region. Each band has its own independent bypass switch. A global hard-wire bypass completes the control layout. Inductors in the filter path give the correction a different character from RC-based designs: gain curves are asymmetric and behave similarly to transformer saturation at higher correction values. Q is adjustable from 0.3 to 6. Correction range: ±10 dB per band. Output impedance: 600 Ω, input: 10 kΩ. Maximum output level: +26 dBu. Internal 115\/230 V power supply. Power consumption: 25 W.\u003c\/p\u003e\n\n\u003ch3\u003eInductors instead of capacitors – where the different character comes from\u003c\/h3\u003e\n\u003cp\u003eStandard active EQs build their filter sections on RC circuits (resistors and capacitors). The iQ. Inductor Equalizer uses inductors – coils – as the reactive elements in the filter sections. Inductors behave differently from capacitors in the signal path: their phase characteristic, magnetic saturation behaviour, and interaction with the rest of the circuit at higher signal levels all differ from RC equivalents. An inductor can saturate in a way similar to a transformer, introducing subtle harmonic colouration at higher correction values that RC filters do not generate. Simultaneous boosting and cutting at nearby frequencies – a classic tonal shaping technique in analog equalizers – produces asymmetric, non-cancelling curves with a phase signature that digital EQ cannot replicate. Each of the four bands can be bypassed individually without affecting the others.\u003c\/p\u003e\n\n\u003ch3\u003eFour bands with overlapping ranges – for precise and creative work\u003c\/h3\u003e\n\u003cp\u003eThe SUB band covers 28–300 Hz (shelf), BASS covers 280 Hz – 3 kHz (peak), MID covers 2.2–12.5 kHz (peak), and HIGH covers 8–25 kHz (shelf). The overlapping band boundaries allow complex correction curves combining two bands in the same frequency region with different Q values and different gain amounts – for example, a broad bass boost at Q 0.3 simultaneously with a narrow notch within the same range at Q 6. The dual-mono configuration means each stereo channel has a fully independent four-band equalizer; the unit can work as a stereo processor with matched settings or as two independent mono processors in a single rack unit. Crosstalk: 100 dB. Frequency response: 20 Hz – 20 kHz ±0.1 dB.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e4-band parametric equalizer, dual-mono, with inductors in the filter circuits\u003c\/li\u003e\n\u003cli\u003eOverlapping band frequency ranges – two bands operable simultaneously in the same region\u003c\/li\u003e\n\u003cli\u003eSUB: 28–300 Hz (shelf) | BASS: 280 Hz – 3 kHz (peak)\u003c\/li\u003e\n\u003cli\u003eMID: 2.2–12.5 kHz (peak) | HIGH: 8–25 kHz (shelf)\u003c\/li\u003e\n\u003cli\u003eQ: 0.3–6 (each band independently)\u003c\/li\u003e\n\u003cli\u003eCorrection range: ±10 dB per band\u003c\/li\u003e\n\u003cli\u003eIndividual bypass per band + global hard-wire bypass\u003c\/li\u003e\n\u003cli\u003eInductors saturate like transformers at higher correction values\u003c\/li\u003e\n\u003cli\u003eCrosstalk: 100 dB\u003c\/li\u003e\n\u003cli\u003eInternal 115\/230 V power supply\u003c\/li\u003e\n\u003cli\u003e3-year manufacturer warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: inductor parametric equalizer, dual-mono, rackmount\u003c\/li\u003e\n\u003cli\u003eChannels: 2 (dual-mono)\u003c\/li\u003e\n\u003cli\u003eBands per channel: 4 (SUB, BASS, MID, HIGH)\u003c\/li\u003e\n\u003cli\u003eBand ranges: SUB 28–300 Hz \/ BASS 280 Hz–3 kHz \/ MID 2.2–12.5 kHz \/ HIGH 8–25 kHz\u003c\/li\u003e\n\u003cli\u003eQ: 0.3–6\u003c\/li\u003e\n\u003cli\u003eCorrection range: ±10 dB\u003c\/li\u003e\n\u003cli\u003eBypass: global hard-wire + individual per band\u003c\/li\u003e\n\u003cli\u003eInput impedance: 10 kΩ (balanced)\u003c\/li\u003e\n\u003cli\u003eOutput impedance: 600 Ω (balanced)\u003c\/li\u003e\n\u003cli\u003eOperating level: +4 dBu\u003c\/li\u003e\n\u003cli\u003eMaximum input level: +22 dBu\u003c\/li\u003e\n\u003cli\u003eMaximum output level: +26 dBu\u003c\/li\u003e\n\u003cli\u003eCrosstalk: 100 dB\u003c\/li\u003e\n\u003cli\u003eFrequency response: 20 Hz – 20 kHz ±0.1 dB\u003c\/li\u003e\n\u003cli\u003ePower supply: 115\/230 V, 50\/60 Hz (internal)\u003c\/li\u003e\n\u003cli\u003ePower consumption: 25 W\u003c\/li\u003e\n\u003cli\u003eShipping weight: 4 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"IGS Audio","offers":[{"title":"Default Title","offer_id":54001634869585,"sku":"47374","price":3378.15,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/IGSAudioiQ.InductorEqualizer1.jpg?v=1781176235","url":"https:\/\/wrdtunes.com\/products\/igs-audio-iq-inductor-equalizer","provider":"Wired Tunes","version":"1.0","type":"link"}
