APB-DynaSonics' ProDesk-8 Medium-format front-of-house consoles incorporate a wealth of professional features derived directly from the company's APB Spectra and ProDesk-4 Series of consoles. Intended for use in Production, AV and Contracting applications, ProDesk-8 stresses simple operation while providing uncompromised audio quality in a compact package. ProDesk's audio design is based on our critically acclaimed Spectra Series consoles. This includes the use of minimum phase-shift circuitry, expressive EQ and integrated Burr-Brown mic preamplifiers used in a proprietary front-end circuit. In addition to superior audio quality, reliability and serviceability are also primary design criteria for ProDesk. Internal construction is based upon a series of passive motherboards and multiple active daughter boards. The active electronics of a single input channel is designed onto field-replaceable electronics modules. Modular Mic/Line input channel configurations of 24, 32, 40 and 48 are available plus all version of ProDesk-8 also include 4 Stereo Line input channels, one channel of which is fitted with USB digital audio inputs. Cosmetics and mechanical structures are similar to Spectra, but with a narrower module pitch and shallower front to back dimensions resulting in a more compact design. Special provision are provided for overall remote muting of the Left-Right, Center, and Mono outputs as well as Group, Auxiliary and Matrix outputs by a rear panel opto-isolated phoenix connector.
