This insert can also be used for compressor \"keying\". A switch on the front panel allows the user to monitor the side chain insert and switch it in and out of circuit.

Instead we couple direct to the Class A (BE41) amplifier modules with hi-quality WIMA capacitors.  This approach presents a much less reactive load to the microphone and allows it breathe better.  In other words, the QSP is like an extension to the microphone and this means you can clearly hear the differences between all microphone types and brands.  The HI Z - LO Z switch allows you change the load the microphone sees, and this can produce subtle tonal changes depending on the type of microphone.\u003cbr\u003e \u003cbr\u003e Another advantage of the direct coupled input is noise - or lack of it. You will discover the QSP has an extremely low noise floor making it useful for low output microphones such as ribbons.  The low noise plus the high output headroom results in a preamp with 92dB dynamic range at full gain of 70dB.\u003cbr\u003e \u003cbr\u003e In addition to the four mic inputs, you also have four high impedance instrument inputs on the front panel.  These inputs can be used for keyboards and instruments with unbalanced pickups.  Both the mic and line inputs benefit from the sound of the Lundahl output transformer which exhibits an incredible frequency response right out to 250kHz, whilst adding a subtle amount of harmonic distortion at the lower frequencies.   Transients are preserved and the bottom end sounds full making the QSP-20 the perfect choice for all music styles.\u003cbr\u003e \u003cbr\u003e \u003cspan style=\"font-weight: bold;\"\u003eApplications:\u003c\/span\u003e\u003c\/p\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eModern music recording\u003c\/li\u003e\r\n\u003cli\u003eAcoustic music recording\u003c\/li\u003e\r\n\u003cli\u003eMobile recording set ups\u003c\/li\u003e\r\n\u003cli\u003eDrums!\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eFeatures:\u003c\/span\u003e\u003c\/p\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eThe vivid sound of discrete Class A amplifiers in the signal path\u003c\/li\u003e\r\n\u003cli\u003eThe lush tone of Lundahl audio output transformers\u003c\/li\u003e\r\n\u003cli\u003eUp to 70dB of gain\u003c\/li\u003e\r\n\u003cli\u003e+28dBu output headroom\u003c\/li\u003e\r\n\u003cli\u003eCulmination of 20 years design experience\u003c\/li\u003e\r\n\u003cli\u003eRobust chassis construction\u003c\/li\u003e\r\n\u003cli\u003eOn board linear power supplies - no wall warts\u003c\/li\u003e\r\n\u003cli\u003eEasy to use control layouts\u003c\/li\u003e\r\n\u003cli\u003eCompetitive pricing\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"Buzz Audio","offers":[{"title":"Default Title","offer_id":44450066399335,"sku":"72748","price":1871.25,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/buzz_quad_studio_preamp_1_0cbab38c-656f-4eae-954b-40cb44fee403.jpg?v=1787091548"},{"product_id":"buzz-audio-tonic-t1009-used","title":"Buzz Audio Tonic #T1009 (Used)","description":"Before modern semiconductor technology, audio filters and equalizers were made with passive components - capacitors and wound coils of wire that formed inductors (or chokes).

This piece is an excellent choice for tracking bass guitar, but will also find application on vocals and other general compression tasks.\u003cp\u003eThe SOC-1.1 Audio Compressor is based on the Light Dependant Resistor (LDR) technology from the past, but incorporates a unique \"Differential Drive Side Chain\" topology and our own Opto module design to create a more adjustable and faster compression characteristic. Gain reduction is totally passive, there are no distortions introduced from semiconductor elements and the signal path is kept to a minimum. LDR selection and matching within a stereo unit ensures accurate tracking compared to vintage LDR designs.\u003c\/p\u003e\u003cp\u003eA common problem with older opto compressor designs (and many modern ones!) is the inherent slow attack time of the LDR elements, which can cause sibilance problems and audible \"pumping\" effects. A special \"speed up\" circuit within the side chain section of the SOC-1.1 effectively reduces the attack time to less than 1mS (in fast attack mode). We believe this is the fastest attack time of any LDR based compressor on the market today and makes it suitable for stereo mixdown (2 buss) compression tasks.\u003c\/p\u003e\u003cp\u003eAll the features available on the SOC-1.1 allows users to create many different flavours of compression, from full on squash to just gentle levelling.
