The charming sound of this vintage technology combined with the modern 120V technology results in a very special equalizer.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eBoost\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eOnly one filter​\u003c\/strong\u003e\u003cbr\u003eAll control functions are part of only one passive filter.\u003cbr\u003eThere are three frequency ranges:\u003cbr\u003eLow Freq \/ Mid Freq \/ High Freq\u003cbr\u003eEach with a cut control on the left and a boost control on the right.\u003cbr\u003eIn the middle is the output control.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eDesign\u003c\/strong\u003e\u003cbr\u003eA passive filter has no amplification stages. It can therefore only be lowered. If one frequency is to be boosted, all the others must be lowered. Behind the filter there is a stage that makes up for the lowered overall level. Since low noise is particularly important here, since up to 20 dB can be made up for, the 120V technology comes into its own.\u003cbr\u003e\u003cbr\u003eThe entire passive filter (variable resistor, capacitor and coil) provides a very nice sound characteristic. Besides the choice of components, the charging behaviour of the capacitors and the saturation behaviour of the coils play a major role in this. The resulting relative inertia compared to potentially very fast active filters is the reason for a pleasant, musically advantageous sound characteristic. We would choose smoothness and transparency as well as strikingly silky highs and pithy basses as a description that suits our perception.\u003cbr\u003e\u003cbr\u003eDuring fine-tuning, through component selection, in countless listening sessions, the emphasis was on achieving the most musical sounding curves possible, which, for example, need fear no comparison with a Pultec EQ from the 1950\/60s. Only without all the disadvantages of a 60 year old original, such as the very high background noise, but above all the very limited frequency selection.\u003cbr\u003e\u003cbr\u003eAnother highlight of the PASSEQ is the HF+ band, which has been extended by the frequencies 25 kHz and 35 kHz and sounds so incredibly good that you don’t want to switch it off.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAnalog inputs \u0026amp; output; XLR (balanced)\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMaximum input \u0026amp; output gain: 32.5 dBu\u003c\/li\u003e\n\u003cli\u003eInput impedance: 20 kΩ\u003c\/li\u003e\n\u003cli\u003eOutput impedance: 75 Ω\u003c\/li\u003e\n\u003cli\u003eCommon mode rejection: -60 dBu\u003c\/li\u003e\n\u003cli\u003eFrequency range (-3 dB): 10 Hz – 200 kHz\u003c\/li\u003e\n\u003cli\u003eCrosstalk (1 kHz): -108 dBu\u003c\/li\u003e\n\u003cli\u003eTHD + N (+30 dBu, 1 kHz): 0.0012 %\u003c\/li\u003e\n\u003cli\u003eNoise (A-bewertet): -95.2 dBu\u003c\/li\u003e\n\u003cli\u003eDynamic range: 134.5 dB\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eInternal Linear Power Supply with Shielded Toroidal Transformer\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOperating voltage for analog audio: +\/- 60 V\u003c\/li\u003e\n\u003cli\u003eOperating voltage for relays and LEDs: + 12 V\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMains Power Supply\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMains voltage (selectable, see fuse chamber): 230 V AC \/ 50; 115 V AC \/ 60 Hz\u003c\/li\u003e\n\u003cli\u003eFuse for 230 V: T 500 mA\u003c\/li\u003e\n\u003cli\u003eFuse for 115 V: T 1 A\u003c\/li\u003e\n\u003cli\u003ePower consumption: max. 15 VA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions \u0026amp; Weight\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eW x H x T (W x H x D (width x height x depth) x Höhe x Tiefe)\u003c\/li\u003e\n\u003cul\u003e\n\u003cli\u003e482 x 132 x 300 mm\u003c\/li\u003e\n\u003cli\u003e19 x 5.2 x 11.8 inch\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003eUnit weight\u003c\/li\u003e\n\u003cul\u003e\n\u003cli\u003e10.2 kg\u003c\/li\u003e\n\u003cli\u003e22.49 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003eShipping weight (incl. packaging)\u003c\/li\u003e\n\u003cul\u003e\n\u003cli\u003e11.9 kg\u003c\/li\u003e\n\u003cli\u003e26.24 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMade in Germany\u003c\/strong\u003e\u003c\/p\u003e","brand":"SPL","offers":[{"title":"Default Title","offer_id":41150587470003,"sku":"SPL-PASSEQ","price":494510.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0657\/6821\/files\/spl-equalizers-spl-passeq-passive-mastering-equalizer-30662467027123.jpg?v=1687236711","url":"https:\/\/www.bajaao.com\/hi\/products\/spl-passeq-passive-mastering-equalizer","provider":"BAJAAO.COM","version":"1.0","type":"link"}
