Description
The RDL SF-PA50AX is a SysFlex series 50W 70/100V mono audio amplifier designed to convert one analog input to a constant voltage amplified output for A/V technicians, system installers, and audio engineers in office buildings, retail environments, and educational facilities. Its Class-D output stage delivers 50W of RMS power at 70 or 100V from a balanced or unbalanced analog input, which offers adjustable gain via a rear-panel, single-turn potentiometer.
Connect a balanced analog source to the mono terminal block input, or utilize the unbalanced 3.5mm stereo mini jack to route signal from a mobile device. The terminal block output accommodates connection to 70 or 100V speakers, and a detachable terminal block is provided for hookup of remote control of the internal VCA. Thermal and short-circuit protection guard against electrical damage and unintended shutdown.
The SF-PA50AX supports powering via the included 24 VDC external power supply (power cord available separately), or from proper wiring to the terminal block power input. Engineered and manufactured in the USA, it boasts a durable metal enclosure for reliable toughness.
