Owner’s Manual

SPEAKER SYSTEM

SUBWOOFER

Thank you for choosing this YAMAHA speaker system. In order to take maximum advantage of the speaker’s fea-

tures and ensure maximum performance and longevity, please read this manual carefully before using the speaker

system. Keep the manual in a safe place for future reference.

PRECAUTIONS

PLEASE READ CAREFULLY BEFORE PROCEEDING

* Please keep this manual in a safe place for future reference.

WARNING

Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical

shock, short-circuiting, damages, ﬁre or other hazards. These precautions include, but are not limited to, the following:

• Do not open the device or attempt to disassemble the internal parts or

modify them in any way. The device contains no user-serviceable parts.

If it should appear to be malfunctioning, discontinue use immediately

and have it inspected by qualiﬁed Yamaha service personnel.

• Do not expose the device to rain, use it near water or in damp or wet

conditions, or place containers on it containing liquids which might

spill into any openings.

CAUTION

Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage

to the device or other property. These precautions include, but are not limited to, the following:

• If you use a stand, make sure to observe the following precautions in

order to avoid toppling the device or causing damage to the internal

components.

- Check the stand’s speciﬁcations and make sure that it is sturdy enough to

support the weight of the speaker.

- Mount only one speaker on each speaker stand.

- Use the supplied screws if included.

- Tighten fastening screws securely.

- Use the speaker stands with their legs fully opened.

- Use the stand at a height of less than 140cm (55").

- Add weight such as sand bags around the stand legs to prevent them from

falling over.

- Remove the speakers from the stands before moving the stands or adjusting

their height.

- Limit the number of people around the placed stand.

We recommend using the TS-80 and TS-90 speaker stands

manufactured by Ultimate Support Systems, Inc. (sold separately) to

support the speakers.

• If you use the metal socket on the subwoofer for mounting of a satellite

speaker, use a pole no longer than 90cm (35.4") with an outer diameter

of 35mm (1-3/8"). Use of any other size pole may cause the device to

fall, and result in injury or damage to the internal components.

• When transporting or moving the device, always use two or more

people. Attempting to lift the device by yourself may damage your back,

result in other injury, or cause damage to the device itself.

• Before moving the device, remove all connected cables.

• Do not use the speaker’s handles for suspended installation. Doing so

can result in damage or injury.

• Do not expose the device to excessive dust or vibrations, or extreme

cold or heat (such as in direct sunlight, near a heater, or in a car during

the day) to prevent the possibility of panel disﬁguration or damage to

the internal components.

• Do not place the device in an unstable position where it might

accidentally fall over.

• 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.

• 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 4). 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.

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. (On the subwoofers, the poly switch

protects the woofer and a similar routine should be followed if the output is lost.)

• Use only Neutrik NL4FC plugs for connecting Speakon connectors.

Before Making Connections

■Phone Plug Wiring

Phone plugs for connection to the phone jack inputs should be wired as

shown on the right. Be sure to use proper speaker cable — NOT shielded

instrument or line cable — for all speaker connections.

■Neutrik NL4FC Plug Wiring

If you will be using the Neutrik connectors for speaker input,

wire the plugs as shown to the right. Be sure to use proper

speaker cable — NOT shielded instrument or line cable — for all

speaker connections.
