Primary winding can be used to convert the output impedance of any direct-coupled power amplifier upward or downward to effectively match the impedance of a particular loudspeaker system
Also has an isolated secondary winding to allow usage with 70 and 100 volt systems
Utilizes punched and welded bottom plate for convenient mounting
Heavy-duty screw-type terminals for positive connection from the power amplifier and to the external speaker wires
Attached label provides terminal identification and voltage/power ratings to aid you in the proper connection and usage
