The P9HW is a wired, two-channel stereo personal monitor with individual mix controls. It delivers improved audio clarity and reduced feedback onstage versus traditional speaker wedges. Listen to one or two channels of audio from the mixing console through earphones, using Mix Mode technology to customize the mono blend or stereo mode to set the left/right balance. A four-band EQ and volume limiting further individualize the sound. Two standard AA batteries provide up to 6 hours of continuous use. The optional SB900 rechargeable battery (sold separately) extends runtime and allows easy in-unit charging. With a compact and rugged aluminum body, the P9HW ensures a long lifetime of use and easily clips onto a belt or guitar strap. Y-splitter cable included for connection to audio sources.
