Azden APS 25b-VH2 Battery Powered 20 Watt Multi-Function 2-Way Speaker System, with 2 installed VHF Wireless Receivers, & 31HT Handheld Microphone / Transmitters.

• The APS 25b-VH2 battery powered speaker system is a fully self-contained wireless sound reinforcement system with two VHF wireless handheld microphones.
• 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 re-chargeable 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-VH2 includes two APS-VR VHF receiver modules and two 31HT microphone / transmitters.
