PA AUP240B 240W Class-D Power Amplifier (100V/8Ω)

When a school hall, retail floor or house of worship needs reliable sound that simply works, the Proel AUP240B answers with 240W of clean, dependable power in a single rack space. Its Class-D switching design pushes efficiency up to 85%, so it runs cooler, draws less from the mains and costs less to keep on all day. Dual outputs cover both worlds: a 100V constant-voltage line for long multi-speaker distributed installs, and an 8-ohm output for direct low-impedance Hi-Fi or stage monitoring. A balanced Euroblock input with its own level control makes wiring to a mixer or preamplifier quick and hum-free, while a switchable high-pass filter keeps low-frequency rumble out of the speaker line. The amplifier drops into standby after 60 seconds of silence to save energy, and a full protection suite - short-circuit, overload, thermal, clip and DC - with at-a-glance LED indicators means it has been built and tested to stay running, shift after shift.
