1 Headphones connector (3.5 mm stereo mini jack)

Use for a headphones connection. When a headphones connection is made, no sound is output from the speakers.To protect your hearing, make sure that the volume is low before headphones are used.• Do not use headphones with a loud volume for a long time. Otherwise, your hearing may be damaged.• Make sure that the volume of the audio devices is at minimum before headphones are connected. A sudden loud sound may damage your hearing. 2 VOL (volume) control

Controls the volume of both speakers and headphones.

The volume becomes louder as the VOL control is rotated to the right,

and quieter as it is rotated to the left.

The Loudness control function of the speakers allows you to enjoy rich

bass tone sounds even at low volumes.

It automatically corrects the sound volume level from the speakers to

allow you to hear the best possible sounds. When you use the speakers connected to an external device, such as your TV, computer, portable player, etc., adjust the output sound level as follows.a After you connect the speakers to an external device, turn on the power of the speakers and then rotate the VOL (volume) control to the 2 o’clock position (right illustration).b Adjust the volume of the external device to its loudest output level, without annoying blaring or distortion.For details about external devices, see their instruction manuals. c Rotate the VOL control of the speakers to adjust the volume to the desired level.

will light up. Also, the auto-standby mode will be available. Even when the speakers are turned off or are in standby mode, they consume a small amount of electricity. This unit has a function that automatically activates standby mode

(power save mode) when this unit is turned on and no audio signal is

input or when the connected device is playing at a low volume for a

certain amount of time (about 30 minutes).

In standby mode, the indicator light goes off.

When a connected device is played while the speakers are in standby

mode, the speakers activate automatically and sound is output.

When p (power) is pressed again, the speakers turn off. • The time before entering standby mode is only a guide. It varies depending on the usage environment.• If the sound from a connected device is too low, the speakers may not activate. In this case, turn up the volume of the connected device.• If you are using devices, such as mobile phones, which emit electromagnetic waves near the speakers, the speakers may activate by themselves, or not enter standby mode. 4 AUDIO INPUT 1/2 (input connectors)
