Important Information
Caution: The XRT30 Bass Section Cabinet weight is 192
pounds (87.1kg) and the High Frequency Column
weight is 82 pounds (37.20kg) net. It requires two or
more persons to safely handle each section.
1. It is very important that Loudspeaker Cables of adequate size
be used, to ensure that there will be no power loss or heating.
Cable size is specified in Gauge numbers or AWG (American
Wire Gauge). The smaller the Gauge number, the larger the
wire size:
If the Loudspeaker Cables are 25 feet (7.62m) or less, use at
least 18 Gauge (AWG) wire size or larger.
If the Loudspeaker Cables are 50 feet (38.1m) or less, use at
least 14 Gauge (AWG) wire size or larger.
If the Loudspeaker Cables are 100 feet (76.2m) or less, use at
least 12 Gauge (AWG) wire size or larger.
The Loudspeaker Connection Terminals can accept up to 12
Gauge (AWG) wire.
2. For additional connection information, refer to the owner’s
manual(s) for any component(s) connected to the XRT30
Loudspeaker.
3. The XRT30 has built-in speaker protection in the form of six
automatic resetting solid-state devices as part of the
crossover networks. Two protect the tweeters, one for the
midranges and three for the woofers. The characteristics of
this protection are that a certain amount of overdrive is
allowed but extended periods of overdrive will trigger
protection. If an obvious lack of high, mid or low frequencies
is noticed, the Loudspeaker Protection Device may have
activated. The protection devices will automatically reset
when the volume control is reduced significantly and kept low
until the output of the affected Loudspeaker Element returns
to normal.
4. When the XRT30 Loudspeaker System is driven by more than
one amplifier, the output levels of the different amplifiers
connected to the Loudspeaker System must be adjusted to
achieve a proper balance between the low, midrange and high
frequencies reproduced. This adjustment is best achieved
through the use of audio test equipment operated by a
qualified installer.
