[. . . ] The Apex435 is also the microphone of choice for saxophones, flutes, brass or woodwinds, acoustic guitars or acoustic bass where subtlety and clarity is paramount. In live sound applications and remote recording Apex435's cardioid pattern offers excellent feedback rejectionand better isolation and will give you the best results on most vocal applications and a wide range of solo instruments including background brass and woodwinds, acoustic stringed instruments (violin, viola and cello), drums and percussion. Note: The cardioid symbol on the microphone housing denotes the `live side', or front face of the microphone that in all cases should face the performer. The Apex435 is a professional wide-diaphragm, cardioid condenser microphone with an internal -6dB 100Hz low frequency roll-off switch. To set the cutoff switch, simply unscrew the bottom of the microphone housing, slide the microphone body off of the chassis and look for the simple blue switch in the middle of the microphone circuit board. In virtually all recording and live sound applications, the low frequency roll-off should be engaged to reduce handling noise and low frequency `rumble' at source.
