DRIVER PROTECTION:
The horn loudspeaker should not be
operated at frequencies below horn
cut-off. It is suggested that any pro-
gram material be high-passed at 400Hz with a 6dB
per octave filter. This can be done by a low level fil-
ter 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 termi-
nal connections without loosing hardware.
Screwdriver adustable rotary dial adjusts power
taps on the 25/70/100V transformer.
