Acoustical Specifications and Wiring
Recommended Wire Gauges
The loudspeakers should be connected to the amplifier outputs with heavy-gauge wire. To minimize power loss, larger
diameter wire should be used for longer lengths. The following chart can be used as a guide.
Note:
All wiring shall conform to applicable local and/or national electrical codes.
Verify that the polarity of the amplifier outputs are connected properly to the loudspeaker.
Internal Configurations
All Panaray
®
loudspeakers ship with a selectable internal crossover.
Each speaker ships in the passive position, but you can change the configuration from passive to bi-amped or bi-amped
dual mid-range (LT 3202
®
-III only).
• In passive mode — the internal passive crossover network is utilized, and a single amplified signal is connected to the
loudspeaker. This requires only one set of input connections and one amplifier channel.
• In bi-amplified mode — the mid-frequency and high-frequency drivers are accessed through separate pins on the NL8
connector. Two sets of connections and two amplifier channels are required. Bi-amplified mode allows additional control
of the balance between the mid-frequency and high-frequency levels.
• In bi-amplified dual mid-range mode — the mid-frequency and high-frequency drivers are accessed through separate
pins on the NL8 connectors. Three sets of connections and three amplifier channels are required. Bi-amplified dual mid-
range allows independent control of two sets of V2 mid-frequency drivers as well as control of the high-frequency driver.
Note:
There are no passive components in line when bi-amp or bi-amp dual mid-range configurations are selected.
All Panaray LT loudspeakers require active equalization. Do not operate the loudspeakers without the proper active
equalization for the particular loudspeaker and operating configuration. Failure to do so may result in permanent damage
to the loudspeaker.
See the Active Equalization section for more details.
