Descripción

Previo de alta gama entradas y salidas balanceadas. xlr, inside fully balanced esto se encuentra en previos de un precio muy superior. conversores de digital a analogo de alta calidad. this model is a very versatile beast - it has full dolby digital and dts decoding, courtesy of motorola, but it can also be used for straight audio. it even has a command button labeled pure audio , while its natural complement, power amplifier pa250 b, also has a command button labeled 2ch/5ch . the casing is typically thule - sheet metal, thick front aluminium fascias, with a slight slope, all of it beautifully machined to very high standards. and of course, heavy, really heavy, which is good, since weight tends to decrease vibration. the preamp uses a multitude of integrated circuits, with no less than 13 regulated power supply lines (all using lm317/337 regulators, properly bypassed and protected). the video lines are especially impressive - their bandwidth is all of 80 mhz, way over what is actually needed, but in return, with little loss, if at all detectable. the audio lines use what must be thule s standard equipment, burr-brown s opa 2134 fet input op amps. now, these are far removed from the usual cheap and nasty ics, and are in fact intended for audio use. they are relatively fast (20v/us), and fet inputs guarantee high input impedance, thus enabling excellent signal transfer characteristics. no mechanical pots here - it s all done using national semiconductor s lm1792 ladder network controls, and with no less than four of them. the controls are thus electrical, and given to the remote control, with the notable exception of the volume, which may also be adjusted using the centrally mounted knob. selection of source is via high quality, sealed, gold plated contact relays, while solid state devices provide the necessary logic. very high tech indeed. the rca cinch connectors are all gold plated
