Assembling the AM Loop Antenna

1. Bend in the direction of the arrow.
   
2. Insert into the hole.
   

Speaker Connections

Connecting the Speaker Cables Check the left (L) and right (R) channels and the + (red) and – (black) terminals on the set and the speakers to be used and interconnect the cables to the same polarities.

1. Peel off about 10 mm of the sheathing at the tip of the cable, twist the core wire and terminate it.
   
2. Turn the speaker terminal counterclockwise to loosen it.
   
3. Insert the speaker cable's core wire into the base of the speaker terminal.
   
4. Turn the speaker terminal counterclockwise to tighten it.
   

When using a banana plug

Tighten the speaker terminal firmly before inserting the banana plug.

NOTE

• Use speakers with an impedance of 6 to 16 Ω/ohms. The protection circuit may be activated if speakers with an impedance other than specified are used.
• Connect the speaker cables in a way that they do not stick out of the speaker terminals. The protection circuit may be activated if the core wires touch the rear panel or screws or if the + and – sides touch.
• Never touch the speaker terminals while the power is on. Doing so could cause electric shock.

Protector circuit
The protection circuit will be activated in the following cases:

• When the speaker cable's core wires are touching the rear panel or screws or when the speaker cable's + and – sides are touching
• When the surrounding temperature is extremely high
• When the internal temperature rises due to extended use with a high output

If this happens, unplug the power cord, then check the connections of the speaker cables and input cables. If the set's temperature is extremely high, wait for it to cool off and improve surrounding ventilation. After doing this, plug the power cord back in.

Before Using

Cautions on Installation

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

• If the bass sound is overemphasized when the speakers are installed directly on the floor, set them on concrete blocks or other hard stands.
• Note that placing the speaker on the same stand or shelf as a record player may result in howling.
• Also note that if there is a magnet or any device generating magnetic force nearby, interaction between this device and the speakers can cause the colors on the TV to become blotchy.

• Fasten the speaker cables to the wall, etc., to avoid catching them on your hands or feet and causing the unit to fall.
• Be sure to check for safety after installing the speakers. Afterwards, perform safety inspections at regular intervals to make sure there at the speakers will fall.
  DENON will accept no responsibility for damages or accidents caused by inappropriate choice of the place of installation or improper installation procedures.

Acoustic Sponge

When installing on a desktop or in the corner of your room, the bass may emphasized. Insert sound foam plug in the bass-reflex duct at the back of the SC-M37.
You can adjust the bass sound with the amount of sound foam plug you insert.

• Do not insert the foam plug too deep. The foam plug could fall in and get stuck inside.
• If the foam plug cannot be removed or falls inside, stop using the unit immediately and consult your store of purchase or your nearest repair and inquiry center.

How to Install

Attach four of the included anti-slip pads to the bottom of the unit as shown on the diagram above.

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

• Raising the amplifier's volume excessively and playing with distorted sound could damage the amplifier and speakers. Enjoy the sound at a reasonable volume level.
• When moving the unit, note that applying strong force to the surface of the speaker through the saran net could damage the speaker.

Connections

When connecting, be sure to read the amplifier's owner's manual carefully and connect properly.

• Connect the input terminals on the rear panel of the speaker with the speaker output terminals on the amplifier, using the speaker cables (Supplied).
• Connect the speaker for the left channel to the "L" terminal on the amplifier, the speaker for the right channel to the "R" terminal on the amplifier, making sure to check the polarities ("+" and "–").
• There are various types of speaker output terminals on amplifiers. Check your amplifier's owner's manual.

• Be sure to turn the amplifier's power off before connecting the speakers to the amplifier.
• If the polarities are inverted, the phase may be off and the sound may have no bass component, making it seem unnatural. Be sure to connect the polarities properly.

Connections
Use the included speaker cable to connect the input terminals on the back of the speakers to the amplifier's speaker output terminals.

1. Twist firmly the wires by hand so that they do not stick out and cause short-circuits.
   
2. Loosen the terminal by turning to the left and insert the speaker cable through the hole in the speaker terminal.
3. Tighten the terminal by turning to the right and check that the core wire is not protruding from the hole.

Once connections are completed, pull gently on the speaker cables to check that they are securely connected.

Do not let the core wires of two speaker cables touch each other. Doing so will short-circuit the amplifier circuitry and damage the amplifier.

Removing the Speaker Net

• The net on the front of the speakers can be removed.
• To remove, grasp both sides of the net and pull forward.
• To mount, line up the projecting pieces in the four corners of the speaker net with the holes in the four corners of the cabinet and press in.
