BST UPA60 - 60W 100V Line Mixer Amplifier

BST UPA60 – 60W 100V Line Mixer Amplifier

The BST UPA60 mixer amplifier delivers 60W of 100V line power, designed for PA and BGM systems in small and medium-sized venues. Its compact 1.5U rack chassis features a 5mm brushed aluminum front panel and aluminum knobs, integrating two microphone inputs, two line inputs, a priority input on Mic 1, and a line output. A two-band EQ and multiple protection circuits ensure clear, reliable sound. Thanks to its active outputs (4–16 Ω, 70 V and 100 V), it is versatile for connecting speakers in various configurations and distances.
