Buzz Audio A-Rack

The Buzz Audio A-Rack 8+1 is the result of many requests for a multi channel mic preamplifier system with the same specification as the venerable MA-2.2 True Class A preamp.  To this end, we have designed a system that not only carries mic preamps, but can fitted with other modules when they come available.  Planned additional modules include a Class A Compressor and Stereo Direct Box, initially we offer the MA-1.5 Mic Pre module.

The standard rack bin is three units high and includes the power supply regulator and monitor module on the right.  Due to the high amounts of heat generated by the True Class A circuitry utilized in this design, adequate ventilation should be provided and it is suggested that 1/2u rack space is provided above and below the A-RACK if the unit will be covered with other equipment.  Alternatively, the system can be supplied in a four unit high frame with built in 1/2 unit ventilation areas front and rear.  In addition to the rack mount chassis, the A-RACK can also be supplied in an attractive 4u ventilated desk top enclosure.
