INPUT SELECT
1
4-way selector to match installation loudspeaker to a 70 V or 100 V installation amplifier or an amplifier
with low impedance output (8 Ω/120 W RMS). Select the appropriate position before connecting. Both
middle positions are intended for use with 100 V installation amplifiers.
POWER SELECT
2
4-way switch for selection of the required transformer tap (60 W/30 W/15 W/7.5 W). If 8 Ω/120 W RMS is
selected on the INPUT SELECT switch, the internal transformer is bypassed.
SPEAKER IN/THRU
3
Terminal block for connection of an installation amplifier and for sending the amplifier signal to the
additional loudspeakers in parallel (terminal block supplied). When wiring, please ensure correct
polarity (see illustration above terminal block).
COVER PLATE
4
For outdoor installations, use the supplied cover plate to protect the connectors and switches from
wetness and humidity. The cable glands in the cover plate
ternal diameter of up to 7 mm. Ensure that the rubber gasket is correctly positioned before securing the
cover plate to the speaker housing. Then tighten the locking nuts on the cable glands. Use the supplied
blanking plugs to seal any open cable glands if only one cable is used to control the speaker.
