The \u003cstrong\u003e8900 Dynamic Range Controller\u003c\/strong\u003e was intrinsically developed to react to loudness (rather than voltage) like ears do. \u003c\/p\u003e  \u003cp\u003eThe 8900’s psycho-acoustic approach uses multiple true-RMS detectors, remarkably accurate log converters, and fast peak detectors to respond intelligently to real signal energy, not just electrical level. This innovative design employs unique controls like Crest Factor, Timing, and Release Hysteresis to precisely control the dynamic features of musical performances; one would ordinarily change out the entire unit to gain this flexibility.\u003c\/p\u003e  \u003cp\u003eFamiliar features such as Stereo Link, Soft\/Hard Knee, Ratio, Output Level, as well as the comprehensive 40-segment tricolor Gain\/Loss metering have been carefully optimized for flexible, creative control over a wide dynamic range with a noticeable lack of audible artifacts. A Side Chain Input permits external frequency shaping to be introduced into the detection circuitry. The entire audio path is all-discrete, including the custom-built VCA, for unsurpassed transparency and low-level resolution. The 8900 is a 2U, two-channel unit which requires one 9015 power supply.\u003c\/p\u003e    \u003ch3 id=\"toc_1\"\u003eSPECIFICATIONS:\u003c\/h3\u003e  \u003cp\u003e\u003cstrong\u003eINPUT:\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \u003cli\u003e20 kOhm balanced bridging; Pin 2 hot\u003c\/li\u003e \u003cli\u003e57 dB common mode rejection at 20kHz\u003c\/li\u003e \u003cli\u003e+27.4 dBv maximum before clipping\u003c\/li\u003e \u003cli\u003eIndividually channel swichable on back panel for +4 or -10\u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003e\u003cstrong\u003eTHROUGHPUT\u003c\/strong\u003e:\u003c\/p\u003e  \u003cul\u003e \u003cli\u003e±0.1 dB, 16 Hz to 68 kHz response (controls at zero)\u003c\/li\u003e \u003cli\u003e0.01% Harmonic distortion at any frequency 20 Hz - 20 kHz1, no gain reduction\u003c\/li\u003e \u003cli\u003e0.009% SMPTE Intermodulation distortion2\u003c\/li\u003e \u003cli\u003e30 v\/usec discrete low noise, high performance amplifiers\u003c\/li\u003e \u003cli\u003eno electrolytic interstage or output coupling capacitors\u003c\/li\u003e \u003cli\u003enoise -96.5 dBv bypassed, -74 dB absolute worst case (control position dependent)\u003c\/li\u003e \u003cli\u003erolloff: 3 dB down at 260 kHz\u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003e\u003cstrong\u003eFORM FACTOR - 2 CHANNELS, Each with separate Peak and Dual RMS Detectors:\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \u003cli\u003eDiscrete VCA; Discrete Audio Chain\u003c\/li\u003e \u003cli\u003eFront Panel Sidechain; Stereo and multiple unit control link\u003c\/li\u003e \u003cli\u003e40 Segment Tricolor meter; Meter range -20 to +20, true gain through unit\u003c\/li\u003e \u003cli\u003e4 segment instantaneous ratio meter (approximate indication of soft knee actuation)\u003c\/li\u003e \u003cli\u003ePeak, FastRMS and SlowRMS indicators\u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003e\u003cstrong\u003eOUTPUT:\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \u003cli\u003e+27.4 dBv clipping; unbalanced; Pin 2 Hot\u003c\/li\u003e \u003cli\u003e3 mv output offset, stabilized by D.C. servo correction\u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003e\u003cstrong\u003eOTHER:\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \u003cli\u003eExternal power supply: ±28 volts \u0026amp; ±18 V DC\u003c\/li\u003e \u003cli\u003eSeparate ground and chassis connections at rear\u003c\/li\u003e \u003cli\u003e19” x 3 1\/2” rack case, black anodized aluminum, silver legend, 8 1\/2” deep\u003c\/li\u003e \u003cli\u003eWeight: 7 lbs.\u003c\/li\u003e \u003c\/ul\u003e","brand":"GML","offers":[{"title":"Default Title","offer_id":44449743503463,"sku":"48470","price":3895.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/gml_8900_dynamic_range_controller__d0321__used__5103973_971cd7a2-0b9c-44de-86cd-6ba84847fd7e.jpg?v=1787090225","url":"https:\/\/vintageking.mom\/products\/gml-8900-dynamic-range-controller-d0321-used","provider":"Vintage King","version":"1.0","type":"link"}
