Wiring and Setting Up
6. Plug in the Euroblock connector to the speaker.
7. The speaker is fitted with a multi-tap transformer for use in distributed-line systems. Check your system design and amplifier output
to match the Wattage required from each speaker. Select the desired Wattage tap before replacing the rear cover.
CAUTION: the speaker is supplied with the transformer tap switch set in low impedance mode (LOZ). Never connect the speaker to a
70/100 volt amplifier while the speaker is set for low impedance. Always check that the transformer switch is set correctly before use.
Typical connections of speakers in a 70V/100V distributed system
8. Select the LOZ tap for use in stereo systems. The average impedance of each speaker in this range is 8 Ohms.
Typical connections of two speakers in a stereo system.

WARNING: To avoid potential damage to your speaker, ensure that the amplifier is switched OFF prior to connecting or disconnecting any
cables.
WARNING: Before switching the amplifier ON, double check that all connections are secure and that the polarity is correct.
1. Pull out the rear wiring cover to access the removeable Euroblock connector plug and socket.
2. The speakers come with a standard speaker cable gland for EN54-24 applications. Feed the cable through and attach to the Euroblock
connector. Allow enough slack wire, and tighten the cable gland.
3. For speaker-level input connections, use Pins 1 and 2 and make sure
that the wiring polarity is correct, where:
Pin 1 is positive
Pin 2 is negative
4. For connection to additional speakers in a distributed line, use
Pins 3 and 4 to loop thru to additional speakers. Make sure that the
wiring polarity is correct, where:
Pin 3 is positive
Pin 4 is negative
5. Strip off approximately 8 mm (¼") of the outer protective layer of one conductor and twist its inner cores together to prevent shorting
from stray wires. Insert and secure to the Euroblock connector, while ensuring that correct polarity is maintained. Repeat this for all
speaker wires. Gently pull on the wires to verify they are making a secure connection to the Euroblock connector(s).
