SPEAKER SYSTEM

SKR-4700

Thank you for purchasing of the Onkyo speaker system. Please read this manual thoroughly before using it. Following the instructions in this manual will enable you to obtain optimum performance and listening enjoyment from your new speaker system. Please retain this manual for future reference.

Before using this unit

●

The speaker cabinet is made of wood and sensitive to extreme

temperatures and humidity. Avoid placing the speaker system in locations subjected to direct sunlight or in humid places such as near an air conditioner, bathroom, or kitchen.

●

Be sure to turn off your ampliﬁ er before connecting the speaker

system. Connecting it while the ampliﬁ er is on may result in damage to the ampliﬁ er or the speaker system.

●

The nominal impedance of this speaker system is 8 Ω. Use

only ampliﬁ ers capable of handling this impedance.

Precaution on use

●

This speaker system can handle the speciﬁ ed input power

when it is used for ordinary music reproduction. If the following abnormal signals are fed to the speaker, however, an overcurrent may ﬂ ow in the internal circuits, causing burning or breakage of the wires even if the input power is below the speciﬁ ed rating.

1. Noise produced when FM station is not tuned in.

2. Sound produced when fast-forwarding cassette tape deck.

3. High-frequency sound generated by an oscillator, an electronic musical instrument, etc.

4. Oscillating ampliﬁ er signals.

5. Special test signals produced by audio checking CD, etc.

6. Sound produced when connecting or disconnecting audio connection cables. (Always turn off the ampliﬁ er’s power before connecting or disconnecting cables.)

7. Howling when a microphone is used.

1. Strip the insulation of speaker cables, and twist the core wires tightly.

2. While pressing the lever, insert the wire into the hole, and then release the lever.

3. Make sure that the terminals are gripping the core wires, not the insulation.

AV ampliﬁ er

● Turn the sound volume to the minimum and disconnect the power

cord from the ampliﬁ er before connecting the speaker cables.

●

The nominal impedance of this speaker system is 8 Ω. Use

only ampliﬁ ers capable of handling this impedance.

●

Use the supplied speaker cables to connect

Before turning on the ampliﬁ er’s power switch:

●

between speaker’s input terminals and the ampliﬁ er’s speaker terminals as illustrated on

●

the right.

●

Connect the speaker cables securely to the

terminals, with the core wires twisted properly. In this case, make sure that the core wires do not touch each other. Note that a short circuit in core wires may result in damage to the ampliﬁ er.

●

Make sure that the positive (+) and negative (-) speaker cables

do not contact each other. Otherwise, a short-circuit may occur, causing damage to the ampliﬁ er.

Be sure to connect the speaker cables with correct polarity

(connect the speaker’s positive (+) and negative (-) binding posts with the ampliﬁ er’s corresponding speaker terminals). Reversed polarity results in impaired bass-range reproduction, causing mislocalization of the sound image. Also, be sure to connect the Right and Left speakers with the ampliﬁ er’s corresponding speaker terminals.

Pull lightly on the speaker cables to ensure that they are

connected ﬁ rmly.

Placement

For better-quality sound, observe the following precautions when you install the speaker system:

●

Placing the speaker system on several small-diameter supports

generally results in better sound than placing it directly on a wide installation surface. Also note that high quality bass cannot be obtained if the speaker system is unstably positioned. Always use thin discs of cork or metal (such as coins) to seat the speaker stably.

●

Place the Right and Left surround speakers in similar conditions.

If they are placed in extremely different conditions, left right channel balance will be adversely affected.

Using spacers

When using as a Surround Back Speaker

It is very important to place your speakers properly to obtain the optimum sound space for your listening pleasure. The surround back speaker is required for enjoying 6.1ch / 7.1ch surround sound. The surround back speaker will also improve the quality of sound effects for far more realistic acoustics.

Place the speaker so that its height is 1 meter higher than that of the listener's ears.

Speaker care

Your Onkyo speaker is ﬁ nished with a very high quality polymer laminate covering that serves to protect the wood speaker cabinet. Wipe the cabinet periodically with a dry, silicon-embedded or plain soft cloth. The covering may be cleaned with a soft cloth moistened with water and a mild soap. Avoid the use of furniture polishes or harsh cleansers. Use a soft brush or hand vacuum cleaner to remove dust and lint from the grille material.

If the speaker is to be wall-mounted, make sure that the walls are strong enough to support the speaker’s weight. The weight that mounting screws can support varies greatly depending on the wall material and the position of the reinforcing ribs embedded in the wall. Use the thickest and longest possible mounting screws with mounting screw head diameters less than 9 mm and shank diameters less than 4 mm (please consult with your interior designer or contractor).
