Contract 350 RT
2 X 350W Constant Voltage Compatible Installation Amplifier
Product at a Glance
The British Acoustics Contract 350RT is a compact, efficient 2-channel Class-AB amplifier delivering 350W per channel at 4Ω. Designed for commercial and contractor-grade installations, it supports both 70V distributed audio and standard 8Ω/4Ω systems, making it ideal for versatile multi-zone setups. With a damping factor >300, low THD (<0.18% at 1kHz), and input load protection, it ensures stable, long-lasting performance. Features include front panel metering, dual rotary volume controls, and a rugged black aluminium chassis with a matte white front. The Contract 350RT offers reliable, straightforward integration for professional installation workflows.
CRAFTSMANSHIP
Painstakingly Perfect Production
Over the years, craftsmanship has been closely linked with small scale individualistic production. Back in 1972, we started the same way. As we grew in scale & size, it was difficult to build each speaker individually, but quality control was of utmost importance as so switching to a general assembly line was simply not an option. So we wrote up a code, one quite like enigma, to ensure quality control. We selected the right partners, got the right tools, and in cases where those weren't available, we invented them. We grew slower than most as our aim was to last longer than most.
