ENGLISH
You can set the EXT PRE button to ON to separate the preamplifi er and power amplifi er of the E-350, and use an external
preamplifi er or A/V amplifi er with the power amplifi er of the E-350. An example of such a connection is shown below.
Bi-amping means to drive the low frequency range and high frequency range of a loudspeaker with separate
amplifi ers, for higher sound quality.
●
Connect the output of the external preamplifi er to the POWER IN jacks of the E-350.
●
Only the power amplifi er of the E-350 is used in this case. The preamplifi er is inactive. Input
source switching, volume adjustment, and other preamplifi er functions must be performed
at the external equipment.
Left speaker Right speaker
Note:
If you set the EXT PRE button to OFF, the E-350 will
operate normally (using the internal preamplifi er).
