Incorporating a 20 watt amplifier, the APS 25b is a rugged, 2-way speaker with a 5.25" shielded woofer and a 1" wide-dispersion tweeter that produces clear detailed sound for all corporate, educational and commercial applications.

The APS 25b includes a Master Volume control and Tone control to reduce feedback. Individual level controls for each of the four inputs- two wireless, one wired mic level, and one line level-giving you more ways to configure your system. The speaker's variable line level output lets you daisy chain multiple speakers. The high gain mic input shorts automatically to reduce noise when no mic is plugged in.

Included with the APS 25b is the Auto On-Off circuitry triggered by any audio input signal for hands-off system startup; a high impact case for reliability, and an internal rechargeable battery that can operate the speaker for up to 8 hours. The speaker can be used free standing, stand-mounted (5/8x27 threaded holes on the bottom and side) or wall-mounted with the supplied U-mount bracket.

The APS 25b-RH1 includes a APS-IRII infrared receiver module, an IRH-10 and an IRD-10DC external sensor.

For pass-around, use the 2-channel IRH-10 infrared handheld uni-directional mic/transmitter. Multiple emitters around the base and near the mic element flood the room. An anti-roll ring around the mic head keeps the IRH-10 from rolling off a sloping lectern or school desk.
