The MA-303su Single-Channel Portable Wireless PA System from MIPRO is designed for live sound reinforcement applications with small- to medium-sized crowds, such as for schools, places of worship, corporate training, paging, trade shows, street performances, fitness instruction, and other comparable situations. This portable 6 pound PA system can be hand-carried using the fixed carry handle or mounted on a microphone stand. It will last up to 11 hours when powered by its built-in lithium rechargeable battery and can recharge in approximately 4 hours. A 4-level battery indicator displays the status of the battery and the unit may also be powered by an AC adapter.
For sound amplification, the device uses a 60W Class-D amplifier to drive a 5" low frequency woofer and a 1" high frequency tweeter. A 1/8" (3.5mm) input jack allows for connection of an external MP3, iPod, CD player, or other line level source. A built-in USB music player and recorder with remote control allows for direct connection to a computer, and an LCD display shows the track name, number, time, and recording status. An alarm button can also be engaged to generate an emergency warning siren sound. A 1/8" (3.5mm) output jack allows for connection to the input of an external sound device.
The PA system features an integrated UHF diversity wireless microphone receiver with 16 selectable channels as well as auto scan and transmitter sync functionality. This model operates on the 6C: 668 to 692 MHz band. Alternatively, a wired microphone can be connected using a 1/4" (6.3mm) unbalanced microphone input.
