V12 includes those features most-desired by touring and permanent-installation engineers. Full-parametric eq is provided on all input channels. A wealth of outputs are available for unexpected situations. Gold-plated connectors and balanced-cir- cuitry are provided,both internally and externally,for long-term interference-free operation sound fundamentals The sonic performance of the V12 is sure to please discriminating sound engineers and audiences alike,even when the console is pushed hard in demanding applications. In order to maintain high-headroom with low-noise,V12 circuits exclusively employ the latest-generation of integrated circuits (operated on +/-20 volt rails) and studio-grade proprietary-design microphone pre-amplifiers. Dual-VCA elements are the best available fromTHAT Corporation, offering improved performance over single-elementVCA designs. Phase-shift has received special attention in the design,revealing less than five-degrees of phase-shift on lower frequencies and less than 18-degrees on upper frequenciesbetter performance than that observed in significantly more-expensive consoles. wide range of configurations V12 consoles are supplied with either 24,32,40,and 48 mono input channels,plus four full-featured stereo mic/line input channels.Basic configurations for all consoles include Master and Group modules, plus four stereo-input modules that may be used as effect-returns. All other inputs may be individually-ordered as mono-mic/line or stereo-mic/line modules. An optional expansion-system enables the addition of up to two 28-input side cars. Up to three V12 chassis may also be linked together for single-console operation. muting systems Three-types of mute systems provide the appropriate mute system for any application. Microprocessor based systems may be disabled for total manual mute operation. The V12 microprocessor mute system was co-developed with JL Cooper,insuring utmost reliability and industry-standard operation methods. V12 console side-car V12 input expansion capabilities The V12 consoles input capacity may be increased in a number of ways. The first method is simple substitution of stereo modules for mono modules. There is no restriction as to the quantity or location of any modules,except for the 66-position frame,which is restricted to no-more-than 28 stereo-input modules (including the four stereo modules that are provided as standard on all V12 configurations). The second-method links multiple V12 chassis together,using the optional internal-linking electronics and multi-way cable system. Up to three-chassis may be linked together,making up to 156-inputs available. While all functions link-together,specific functions may be selectively-isolated,including the very important solo-functions where multiple operators may not wish to disturb other members of the mixing team operating on master or slaved consoles. This functionality is accomplished via a conveniently-located front-panel solo-isolate switch. The third-method employs the V12 expander-frame system. This is a 28 input-position frame that also includes a two-wide master sectiondelivered with all mono input modules,but optionally configured with any number of stereo modules. Up to two-sidecars can be connected to a master chassis, making available up to 108 input-positions. When three 52-input V12 chassis are linked with two 28-input side-cars,up to 212 input-module positions are then available for use within this single-console system. The inclusion of a master section allows a side-car to be used as a limited- function stand-alone mixer or to allow the local-control of selected outputs, such as effect sends,whose feeds may be isolated from the master console. The side-car provides,in addition to master control from the main console, four local-VCA group channels,eight local-aux outputs and local left/right/mono outputs. These features are especially useful when the console is used as a drum or orchestra mixer. master modules 1+2 built to defy murphys law V12 consoles are constructed to endure the rigors of the road. A segmented mother-board system is employed,thoroughly shock- mounted from the multi-walled chassis. Despite being extremely-rigid, the V12 console is amazingly light. Gold-plated interconnects and con- nectors are used throughout,delivering impeccable performance in even the most harsh environments. also available without microprocessor system RadioFans.CN 收音机爱 好者资料库 v.1.01/24/00 specifications Crest Audio specification literature is available in downloadable PDF format at our website 2000 Crest Audio Inc.
