CAUTION
The POWER switch on this unit will not completely shut off all
power from the AC outlet. Since the power cord serves as the main disconnect device for the unit, you will need to unplug it from the AC outlet to shut down all power. Therefore, make sure the unit has been installed so that the power cord can be easily unplugged from the AC outlet in case of an accident. To avoid fire hazard, the power cord should also be unplugged from the AC outlet when left unused for a long period of time (for example, when on vacation).

Installation and connections

How to install

A speaker’s playback sound is delicately influenced by conditions in the listening room. To produce optimum listening conditions, take due onsideration of the conditions of your installation location before beginning actual installation.

Place the speakers at ear level.
For a natural stereo effect, the right and left speakers should be installed in symmetrical and equidistant positions from the listening position.
To prevent sliding, apply the supplied cushions to the bottom of the speakers.

| WARNING
Store small parts out of the reach of children and infants. If accidentally swallowed, contact a doctor
immediately.
---|---

The speakers should ideally be placed at an angle of 30° to the left and right (for a total of 60°) from the listening position, and facing inward.

VENTILATION CAUTION
When installing this unit, make sure to leave space around the unit for ventilation to improve heat radiation (at least 15 cm at top, 15 cm at rear, and 15 cm at each side).

WARNING
Slots and openings in the cabinet are provided for ventilation to ensure reliable operation of the product, and to protect it from overheating. To prevent fire hazard, the openings should never be blocked or covered with items (such as newspapers, table-cloths, curtains) or by operating the equipment on thick carpet or a bed.

Connections

Disconnect the power cord before making or changing connections.
Read the instruction manuals for the devices you are going to connect with the speakers.
Connect the power cord after all the connections are complete.
Use the supplied power cord.
The input signals to the RCA, STEREO MINI and TRS input terminals are mixed, so please beware of the volume level.

Connecting cords
Connect the supplied speaker cord to the speakers.

Strip about 1 cm of the head of the supplied speaker cord and twist and remove the exposed insulator.
After removing the insulator, thoroughly twist the core wires.
Connect the supplied speaker cord to the speaker terminals on the LEFT and RIGHT sides.
Insert the core wires into the terminals while pressing the claw on the speaker terminal.
Connect the speaker cord with the red line into the + terminal side (red) and the speaker cord without the red line into the – terminal side (black).

CAUTION

After connecting to the terminals, lightly pull the speaker cord to make sure that heads of the speaker cord are securely connected to the terminals. A loose connection might cause audio output to be interrupted or noise to be output.
When connecting the speaker cord, thoroughly twist the core wires, and make sure that the core wires are not protruding out of the speaker terminals. Core wires protruding out of the speaker terminals may come into contact with the rear panel or with each other. This may cause an excessive load to be placed on the amplifier which results in operation stopping or a malfunction.
If a mistake is made with the polarities (+, -) on the LEFT and RIGHT sides when connecting the LEFT and RIGHT speaker cord, normal stereo effect can no longer be obtained.
