Connections

• Before connecting the device to other devices, turn off the power for all

devices. Before turning the power on or off for all devices, set all

volume levels to minimum.

• Use only speaker cables for connecting speakers to the speaker jacks.

Use of other types of cables may result in ﬁre.

• Be sure to observe the ampliﬁer's rated load impedance (see page 4),

particularly when connecting speakers in parallel. Connecting an

impedance load outside the ampliﬁer's rated range can damage

the ampliﬁer.

Handling caution

• When choosing a power ampliﬁer to use with your speakers, make sure

that its power output matches the speakers' power capacity (refer to the

Speciﬁcations on page 18). Even if the ampliﬁer's power output is lower

than the speakers' PGM (program) power capacity, the speakers may be

damaged when clipping of a high input signal occurs. The following

may cause damage to speakers

- Feedback caused when using a microphone.

- Continuous high sound pressure level produced by electronic instruments.

- Continuous high-power output of distorted signals.

- Popping noises caused by turning on equipment, or by connecting or

disconnecting system components while the ampliﬁer is turned on.

• When turning on the AC power in your audio system, always turn on the

power ampliﬁer LAST, to avoid speaker damage. When turning the

power off, the power ampliﬁer should be turned off FIRST for the

same reason.

• Do not operate this device at high volume levels or at a level that is

uncomfortable, since it is capable of producing sound levels that could

cause permanent hearing loss. If you experience any discomfort or

ringing in the ears, or suspect an hearing loss, you should consult

an audiologist.

Special Notice

Protective Circuit (poly switch)

All full-range loudspeakers are ﬁtted with a self-resetting poly switch that protects the high-frequency driver from damage caused by excessive power. If a loudspeaker

cabinet loses high-frequency output, immediately remove power from the unit and wait for two to three minutes. This should be long enough to allow the poly switch to

reset. Reapply power and check the performance of the high-frequency driver before continuing, with the power reduced to a level that does not cause the poly switch to

interrupt the signal.
