Frequently Asked Questions - S-M53 DENON

How to connect the S-M53 speakers to the amplifier?

Turn off the amplifier before connection. Use the supplied cables: connect the red (+) terminal of the speaker to the red terminal of the amplifier, and the black (-) terminal to the black terminal. Respect polarities and left/right channels. Tighten the knobs well.

What cables to use for the speakers?

Use the cables supplied with the speaker. The smooth core wire connects to the red (+) terminal, the ribbed core wire to the black (-) terminal. Do not short-circuit the wires.

Where to place the speakers for optimal sound?

Avoid walls or corners too close to avoid exaggerating bass. If the sound is too strong, insert the foam bungs into the rear ports. Place the speakers on stable surfaces and use the supplied anti-slip pads.

How to clean the speakers?

Use a dry, soft cloth to remove dust. Do not use benzene, thinner, insecticides, or chemically treated cloths without precautions. Avoid touching the speaker cones.

What to do if the bass is too strong?

Insert the supplied foam bungs into the bass-reflex ports on the back of the speakers. Adjust the depth according to your preference. Do not push them beyond the flat surface.

How to avoid magnetic interference with the television?

The speakers have low magnetic leakage, but if color spots appear, turn off the TV for 15 to 30 minutes and then turn it back on. Move the speakers away if necessary. Avoid placing magnets nearby.

Can I use these speakers with any amplifier?

Yes, but check the impedance (6 Ω) and maximum power (60 W IEC). Consult your amplifier's manual for settings. Do not exceed the speakers' maximum input power.

How to install the anti-slip pads?

Turn the speaker over and stick the anti-slip pads (supplied, about 1 mm thick) under the cabinet as shown in the manual. This prevents the speaker from sliding.

What to do if the foam bungs fall inside the speaker?

Stop using the speaker immediately and contact the store or a DENON service center. Do not attempt to remove them yourself to avoid damaging the speaker.

How to remove the speaker grille?

Grasp both sides of the grille and pull forward. To reattach, align the bumps at the four corners of the grille with the holes in the cabinet and press.

1 CAUTIONS ON HANDLING

Cautions on Use – Speaker System

■ Avoid placing the speaker systems in places exposed to direct sunlight for long periods of time or near heaters or other heating equipment.
■ Placing in humid or dusty places may result in damage.
■ Do not apply inputs exceeding the speaker system's max. input (the input which can be applied a short period of time with regular program sources).
■ The output terminals may differ depending on the amplifier being used. Consult the amplifier's instructions.
■ Clipping or other problems may occur in the output waveform when using the speaker systems with a high output and the amplifier's tone controls set to the maximum. Avoid using them under these conditions.
■ Never play such special signals as a tape recorder's fast-forwarding signals or sine waves continuously.
■ When moving the speaker systems, be careful not to apply excess force to the speaker nets. Doing so could damage the speaker units.

Cleaning

■ Use a wiping cloth and wipe lightly to remove dirt from the cabinet and operation panel.
■ When using chemically treated cloths, follow the precautions that have been written for them.
■ Do not use benzene, thinners, or other organic solvents or insecticides on the main unit since they may cause a change in quality or color.

Other Cautions

Note that color blotching may occur on a TV, etc., due to interaction with the speaker system if there is a magnet or an object generating magnetic force nearby.

Examples: (a) When there are magnets on the door of the rack, stand, etc.
(b) When a health device, etc., equipped with magnets is placed nearby.
(c) When toys or other objects using magnets are placed nearby.

■ Note that the illustrations in this instructions may differ from the actual set for explanation purposes.

■ Be sure to keep the operating instructions.

After reading these operating instructions, store them in a safe place. We also recommend filling in the necessary items on the back cover.

CAUTIONS ON HANDLING (continued)

When installing, carefully examine the place and method of installation for safety.

When using a stand, etc., follow the instructions included with the stand and check for safety before installing and using. DENON will accept no responsibility for damages or accidents caused by the unit falling.

Cautions on Installation – Speaker System

The quality of the sound produced from the speaker system is affected by the size and type (Japanese or Western) of the room, as well as by the method of installation. Consider the points listed below before installing the speaker system.

If the bass sound is overemphasized when the speaker systems are installed directly on the floor, set them on concrete blocks or other hard stands.
■ Placing the speakers on a shelf or in a corner can boost the bass level of the speaker. If you want to reduce it, please place the foam plugs in the reflex port tubes that you can find on the back of the speakers.

CAUTION:

• The sound quality can be adjusted by changing the depth of the foam plugs in the ducts.
• Set the foam plugs to the desired depth.
• Never insert the foam plugs deeper than the plate surface.
• If this is done, it may not be possible to get them out and they may fall inside the set.
• If the foam plugs should get stuck or fall inside the set, stop using the set immediately and contact your store of purchase or one of the service centers listed on the included “DENON Service Network”.

■ Note that placing the speaker system on the same stand or shelf as a record player may result in howling.
If there is a wall, glass door, etc., directly in front of or behind the speaker system, cover the wall or door with a thick curtain to prevent resonance and reflection.
The speaker systems are of the low-leakage-flux type and can be used near televisions, but depending on the TV there may be color blotching on the picture. If this happens, turn off the TV's power, wait 15 to 30 minutes, then turn the TV's power back on. The TV's automatic degaussing circuit should reduce the blotching on the picture. If blotching persists, move the speaker further away.
■ Also note that if there is a magnet or any device generating magnetic force nearby, interaction between this device and the speaker systems can cause the colors on the TV to become blotchy.

■ Please stick the included anti-slip pads (cork, approximately 1mm thick) at bottom of the cabinet as below to prevent slipping. (SC-M53 only)

CAUTION:

• To ensure safety, do not place any objects on top or lean objects against the speaker system.
• The speaker may topple down or fall if force is applied to the sides. Be particularly careful to avoid this, as this could cause injury or other serious accidents.
• Fix connection cord to prevent being caught on it and making loudspeakers topping down.

WARNING:

• Be sure to fasten the speaker cords to a wall, etc., to prevent people from tripping over them or otherwise pulling on them accidentally, causing the speaker systems to fall.
• Be sure to check for safety after installing the speaker systems. Afterwards, perform safety inspections at regular intervals to make sure there is no danger that the speaker systems will fall. DENON will accept no responsibility for damages or accidents caused by inappropriate choice of the place of installation or improper installation procedures.

2 CONNECTIONS

Connecting the speaker terminals

* Read the amplifier's operating instructions carefully before connecting, and be sure to use properly.

Be sure to turn the amplifier's power off when connecting the speaker systems.

• Use the included cords to connect the input terminals on the back of the speaker systems (see diagram) to the amplifier's speaker output terminals.
• Connect the speaker system for the left channel amplifier's "L" terminals, the one for the right channel to the amplifier's "R" terminals, matching the polarities ("+" and "-" marks).
• Inverting the polarities will result in unnatural sound, with the phase off or no low bass sound. Also check that all two terminal knobs are tightly fastened.

Connections

(The red terminals on the right side are the “+” terminals, the black ones on the left side the “-” terminals.)

Loosen the terminal knobs, insert the cords core wires, then tighten the knobs.
