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 with a
combined wattage of no more than 80% of the amplifier's output power rating (in the case of
the ZZONE2120PA, this is 120W 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 amplifier is capable of powering one or more low
impedance speakers. There is an option on each zone for either a 8-16Ω 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 ("+" 8-16Ω) wire to the (+) of speaker terminal
and the speaker negative (-) wire to "COM" of the amplifier terminals.
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 RMS loading
from the zone output. Lower power handling may risk damage to the speakers.
