Model SF-PA50A

50 W Mono Audio Amplier

- 70 V or 100 V

APPLICATION: The SF-PA50A is a 50 Watt audio power amplifier that converts one analog input to a 70 V or 100 V constant voltage amplified

output.

An analog audio source may be connected to either the mono balanced terminal block input or to the unbalanced Mini-Jack which sums the left

and right channels to mono. Amplifier gain is set by the installer using a rear-panel single-turn potentiometer with an associated dual-LED VU meter

calibrated to 20 dB below maximum power output.

The SF-PA50A is equipped with an internal VCA for setting the amplifier output level. A detachable terminal block provides for the connection of an

external 10 kΩ potentiometer or a 0 to 10 Vdc control voltage. RDL remote controls are available to provide single-turn, multi-turn (rotary encoder) or

pushbutton (ramp or fixed level selection) user level control. VCA control insures long term noise-free level adjustment.

The module is equipped with both thermal and output short-circuit protection. The high-efficiency Class D output stage produces minimal heat for

all levels of expected voice or music modulation. Upon power-up and during overloads or overheating, an LED MUTE indicator glows yellow and the

output is muted.

The SF-PA50A is equipped to operate from an included external 24 Vdc power supply. The SF-PA50A monitors the amplifier power and limits the

current to protect the power supply from shutting down even during extreme feedback or square wave modulation conditions. A red rear-panel

OVERLOAD PROTECT LED flashes when the SF-PA50A reduces power consumption to prevent shutdown of the power supply.

The SF-PA50A is constructed in a durable, professional all-metal enclosure suitable for free-standing, surface-mounted or rack-mounted operation.

This full-featured SYSFLEX product is engineered and manufactured in the U.S.A for continuous duty in demanding installations. The versatility of

SYSFLEX products adds enormous flexibility in the design and installation of professional A/V systems.

The SysFlex® series is a family of A/V modules providing complex interface solutions at the click of a connector. Certain SysFlex modules provide

connectorized interface between data networks and analog and digital audio devices. Other SysFlex modules include networked and conventional amplifiers

and other application

specific solutions. In RDL’s tradition of versatility, SysFlex modules can be used right where they are needed: Rack-mounted,

Surface-mounted, or unmounted. They are light-weight, compact and easy to install with simple, straightforward switch settings and LED indicators. Modules

quickly snap into the SysFlex rack mount and each is firmly secured with a single screw. The racking system segregates network and power wiring from

the audio and digital audio connectors. For connectorized network audio endpoints and A/V system components that provide unparalleled performance and

advanced features without giving up simplicity and ease of installation, SysFlex is the industry’s best value.
