The Audio Upgrades Mic Pre Card offers high end outboard
mic preamp performance in a low cost miniature package designed
to retrofit the mic preamps in mixing consoles. Unique buffered
current feedback amplifiers are used with a class A discrete
front end offering performance beyond outboard mic pre's. The
small size means it can fit in the tightest packages. Power
requirements are plus and minus 9 to 18 volts with low current
consumption making the preamp ideal for battery powered
applications. 48 volt blocking capacitors are fitted for easy
hookup. Onboard clamping diodes prevent input surges, and the 56
ohm output impedance
drives the most difficult loads, including headphones. With it's
small size and low power drain, the Audio Upgrades Mic Pre Card
can fit almost anywhere, offering "high speed" sound at an
affordable price. Installation is easy, requiring only six
connections. The preamp is ideal for critical music recording as
well as demanding film and post work.
