QUALITY MATERIALS

Enjoy long-term reliability of UL
recognized plastics with UV inhibitors
and a five-year waranty.

DRIVER PROTECTION:

The horn loudspeaker should not be
operated at frequencies below horn
cut-off. It is suggested that any pro­gram material be high-passed at 400Hz with a 6dB
per octave filter. This can be done by a low level fil­ter at the amplifier input or by a series capacitor at
each loudspeaker. Electrolytic capacitors can be
used but they must be non-polarized.

EASY ACCESS & ADJUSTMENT

Includes security cap, partially-captive
screws and swing-open access to termi­nal connections without loosing hardware.

Screwdriver adustable rotary dial adjusts power

taps on the 25/70/100V transformer.
