## Long description

The Alto Professional TS412 is a high-performance 2-way active loudspeaker designed to deliver professional-grade audio for a wide range of applications. With a robust 1250W RMS power output and a frequency response ranging from 44Hz to 20000Hz, this speaker ensures clear, room-filling sound. It features versatile wired and wireless connectivity, including Bluetooth streaming and remote control capabilities via the dedicated Alto App, making it a flexible solution for modern audio setups.
Advantages
The TS412 stands out for its exceptional power-to-weight ratio, utilizing efficient Class D amplification that provides high output without the need for noisy cooling fans. Its integrated 3-channel mixer simplifies setups by allowing direct connection of microphones, instruments, and line-level devices.

When it may not be suitable
This loudspeaker may not be the ideal choice for small, intimate acoustic settings where such high power output is unnecessary and could overwhelm the space.

What to consider before purchase
Ensure you have compatible stands or mounting hardware if you intend to elevate the speakers.

Check the dimensions of your transport vehicle to ensure the 15 kg units fit comfortably.
Usage recommendations
For the best audio performance, always utilize the Alto App to calibrate the Custom EQ settings to the specific acoustics of your venue. When using the speaker in a wedge monitor position, ensure the DSP mode is set accordingly to minimize feedback and optimize vocal clarity.
