Shure FP24 Musical Instrument User Manual


 
General Description
The Shure FP24 is a studio-quality two-channel, portable, stereo
microphone mixer. With assignable L-C-R inputs, built-in slate mi-
crophone, 1 kHz tone oscillator, and headphone monitor, the FP24
is extremely flexible. Its impressive audio performance and com-
prehensive features make it suitable for the front end of any studio

engineers will especially value its compact size, sunlight-readable
LEDs, and rugged mechanical and electrical construction that
make it able to withstand extremes in the field.
