Listening Through Headphones

• When connection cables with resistors are used, the volume level
of equipment connected to the INPUT jacks may be low. If this
happens, use connection cables that do not contain resistors.
Listening Through Headphones
You can use headphones to enjoy the BK-9 without disturbing
those around you, such as at night.
1. Plug the headphones into the PHONES jack located on the
BK-9’s front panel.
2. Use the BK-9’s [VOLUME] knob to adjust the headphone
volume.
Cautions when using headphones
• To prevent damage to the cord’s internal conductors, avoid rough
handling. When using headphones, mainly try to handle either the
plug or the headset.
• Your headphones may be damaged if the volume of a device is
already turned up when you plug them in. Minimize the volume
before you plug in the headphones.
• Excessive input will not only damage your hearing, but may also
strain the headphones. Please enjoy music at a reasonable volume.
