Onkyo SKS-L500 Connecting the Speakers, Using Speaker Mounts/Brackets, Operating Precautions

SKS-L500.fm Page 3 Monday, October 3, 2005 2:33 PM

The plaque of each speaker rotates so that you can posi- tion the speakers upside down.

Caution:

A mounting screw’s ability to support a speaker depends on how well it’s anchored to the wall. If you have hollow walls, screw each mounting screw into a stud. If there are no studs, or the walls are solid, use suitable wall anchors.

Use screws with a head diameter of 9.5 mm or less and a shank diameter of 4 mm or less. With hollow walls, use

a cable/pipe detector to check for any power cables or
water pipes before making any holes.
Leave a gap of 5 mm	Wall
between the wall and the
base of the screw head, as
shown.
(We recommend that you
consult a home installation
professional.)	5 mm

Connecting the Speakers

Read the following before connecting your speakers:

•Turn off your amp before making any connections.

•The nominal impedance of these speakers is 6 Ω. Use only an amp that supports this impedance.

•Pay close attention to speaker wiring polarity. Con- nect positive (+) terminals to only positive (+) termi- nals, and negative (–) terminals to only negative (–) terminals. If the speakers are wired incorrectly, the sound will be out of phase and will sound unnatural.

•Be careful not to short the positive and negative wires.

Doing so may damage your amp.

■Connecting the Speaker Cables

1Strip the insulation from the ends of the speaker cables,

and twist the bare wires tightly.

2	Use the cables to connect each speaker’s
	input terminals to the corresponding
	speaker output terminals on your amp.
	To make a connection, while
	pressing the terminal lever,
	insert the wire into the hole, and
	then release the lever.
	Make sure that the terminals are
	gripping the bare wires, not the insulation.

Using Speaker Mounts/Brackets

Threaded inserts for 5 mm machine screws are provided for wall-mounting with commercially available speaker mounts and brackets (SKC-L500C: rear, SKM-L500S: rear and buttom). Refer to the manual supplied with your mounts or brackets for installation details.

Note:	Mount or bracket
The portion of the screw that
goes into the speaker’s
threaded insert should be			5 mm
between 5 mm and 9 mm
long.
		5–9 mm

Operating Precautions

The speakers can handle the specified input power when used for normal music reproduction. If any of the fol- lowing signals are fed to them, even if the input power is within the specified rating, excessive current may flow in the speaker coils, causing burning or wire breakage:

1.Interstation noise from an untuned FM radio.

2.Sound from fast-forwarding a cassette tape.

3.High-pitched sounds generated by an oscillator, elec- tronic musical instrument, and so on.

4.Amplifier oscillation.

5.Special test tones from audio test CDs and so on.

6.Thumps and clicks caused by connecting or discon- necting audio cables (Always turn off your amplifier before connecting or disconnecting cables.)

7.Microphone feedback.

•The speakers contain strong magnets, so do not put magnetic or iron objects such as screwdrivers close to them. If you do, the object may be attached to the magnets, causing personal injury or damage to the diaphragm.
