Designed for multiple presenters, the Califone PA419Q2 Portable Bluetooth PA provides a 6.5” speaker, two wireless microphone receivers, and two handheld wireless microphones. Each microphone sports a transmission range of 150’. Intended for applications such as in schools and churches, the unit includes both Bluetooth and NFC (Near Field Communication) for quick and easy wireless audio streaming from a Bluetooth-enabled device. It can also accept wired-microphone signals over an XLR-1/4” input.
The unit can provide voice or music amplification out to groups up to 300 people, or in rooms up to 2,000 sq ft. A voice priority feature automatically mutes any music being played back while a connected voice is making announcements. Three seconds after the speaking stops, the music will return to its previous level. Each microphone receiver includes a channel selector, a volume control, as well as audio and RF indicator lights.
The PA system can run on AC power or its rechargeable lithium battery, which is 20% lighter than a comparable lead-acid battery. It can play for at least 2.5 hours on a single charge, and will recharge while playing when connected to an AC power supply.
Additional connectivity includes a digital display with a USB/SD card slot, an RCA input pair, and a stereo 3.5 mm auxiliary input for connecting smartphones and other media devices.
The rear panel also includes a music/speech button, mic/aux/MP3/master volume controls, an RCA line-level output, and a set of composite RCA video outputs. The bottom of the device includes a standard 1-3/8" tripod mounting hole for placement on a stand. The included remote control allows you to adjust the pitch of digital audio by up to ±20% in 3% increments, which can be useful for dance and music teachers. The built-in handle facilitates ease in transportation.
