PA speakers
Alto Professional TX412B
The Alto Professional TX412B is a portable, battery-powered two-way PA speaker with a 12-inch low-frequency driver and a 1-inch titanium-diaphragm compression driver. Alto specifies 600W Class-D amplifier power, divided into 300W LF and 300W HF; this is the stated amplifier output and should not be labelled as a 600W RMS rating. The rechargeable battery allows operation away from a mains outlet, with runtime described by Alto as up to 10 hours. Actual playback time depends on use and operating conditions, so this maximum should not be promised for every performance. A built-in two-channel mixer accepts microphone, line-level and Bluetooth sources. Bluetooth streaming and TWS linking are provided, and an XLR mix output can link further speakers; connected sources or additional equipment may still require cables. Contour EQ is provided for music playback. The cabinet has a pole socket and monitor-angle configuration for practical placement.
