RDL SF-PA50A 50W 70/100V Audio Amplifier (North Am
Product Description
The RDL SF-PA50A 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 potentiometerConnect a balanced analog source to the mono terminal block input - or utilize the unbalanced 35mm 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 shutdownThe SF-PA50A supports powering via the included 24 VDC external power supply and North American power cord - 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
