100V LINE SYSTEMS
For 100V speakers, connect the selected zone output to the first speaker in the zone using
double-insulated speaker wire which has adequate current rating to handle the total output
of the amplifier.
Connect the "100V" output terminal for the selected zone to the positive (+) connection of
the speaker and "COM" output to the negative (-) connection of the speaker. Connect further
speakers in parallel to the first speaker with all positive terminals and connected together
and all negative terminals connected together as shown below.
A 100V line speaker system can comprise of many speakers connected together. The
determining factor for how many speakers can be used on a single amplifier is the power
rating. For most purposes, it is advised to connect as many speakers as needed wi th a
combined wattage of no more than 80% of the amplifier's output power rating (in the case
of the ZZONE6xxxPA, this is 30W per zone output). The terminals of a 100V speaker are
connected via a transformer and if necessary, this transformer may be "tapped" for different
power ratings. These tappings can be used to adjust the wattage (and output volume) of
each speaker in a zone to help achieve the ideal total power of the system for the relevant
zone output.

LOW IMPEDANCE SYSTEMS

Alternatively, each zone output of the ZZONE6xxxPA is capable of powering one or more low
impedance speakers. There is an option on each zone for either a 4Ω or 8Ω speaker output
to determine the minimum impedance. It is essential to select the correct output terminal
when opting for low impedance speakers. For a single 8Ω speaker, connect the positive (+)
wire to the "8Ω" terminal and the negative (-) wire to "COM" For a single 4Ω speaker or for
2 x 8Ω speakers connected in parallel, connect the positive (+) wire to the "4Ω" terminal and
the negative (-) wire to "COM". In either case, the connected load should have a combined
impedance no lower than stated on the terminal. Lower impedance may cause irreparable
damage to the amplifier. The connected speaker(s) must also have a power handling to
accept up to 30Wrms from the zone output. Lower power handling may risk damage to the
speakers.
