Koss KS4380-2 - Speaker Setup

36
Speaker Configuration setup is important to perform
prior to using the surround sound modes. It is possible
to receive multi-channel surround sound without a
center speaker. But for best results with Dolby Pro Logic
and Dolby Digital decoding, at least 5 speakers (Left,
Center, Right, Left Rear and Right Rear) should be
used.
How to change speaker configuration
settings:
1. Press the SPEAKER SETUP button to choose speaker
type. Each time you press the SPEAKER SETUP button,
the speaker type changes as follows:
Subwoofer, Center Speaker, Rear speaker, Center
Delay, Rear Delay.
2. Press the SELECT button change the settings for each
speaker.

Choose if no subwoofer is used.
Front Speaker:
 FRONT : LARGE

When using small compact front speakers, it is
recommended to connect a powered subwoofer to

out frequencies are sent to the front speakers. This can
cause damage to small compact speakers when played at
high volume.

 CENT : LARGE
Use this mode with a large center speaker.
 CENT : SMALL
Use this mode with a small center speaker.

The center channel signal will be divided between the
Front L and R speakers.
