Contract 700 RT

2 X 700W CONSTANT VOLTAGE COMPATIBLE INSTALLATION AMPLIFIER

Product at a Glance

The Contract 700RT is a professional-grade 2-channel amplifier delivering 700W per channel at 4Ω, engineered specifically for fixed installations requiring both power and flexibility. Designed with Class-AB architecture, it combines sonic fidelity with robust performance, supporting both low impedance (4Ω/8Ω) and high-voltage distributed audio systems (70V/100V). It is ideal for retail environments, hotels, worship spaces, and large-scale paging networks.

Built with integrators in mind, the amplifier features Euroblock terminal outputs, XLR signal pass-through, and a compact 2U rackmount chassis with a matte white front panel for unobtrusive deployment. Internally, the 700RT boasts a >400 damping factor, high input CMRR (>60 dB), and protection circuits against DC faults and overload, ensuring long-term reliability even in demanding conditions. The front panel provides precise output metering and dual rotary volume controls, making it easy to monitor and manage levels directly at the rack.

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.
