Cautions Regarding Handling
Maintenance
●
Never connect the speaker output terminals to any ground. Both speaker
terminals carry an active signal due to the full balanced circuit design of
AMP3800.
●
Be careful when connecting active subwoofers or similar devices to the
speaker terminals. A short circuit to the ground may result in damage to
AMP3800 or a broken fuse.
●
The DC voltage at the speaker terminals is not 0 when measuring related to
ground. However, the differential DC voltage from (+) to (-) speaker terminal
is nearly 0 and thus harmless to speakers.
●
Audiophile amplifiers produce heat! Make sure to leave enough open space
around AMP3800 (at least 15cm) for keeping the air circulating. Make sure
you never cover the heatsink and air vents on the top cover, which could
result in an overheating. It is recommended to use AMP3800 in a low-dust
environment.
●
In case of overheating (over approx. 70
℃
) AMP3800 will cut off the
operating power automatically. In this case it is suggested to put the main
power switch to “OFF” position. Otherwise AMP3800 will power ON again
after cooling down.
●
AMP3800 requires no periodic maintenance and contains no user-
serviceable parts. Contact your dealer or an authorized CEC service center
for inspection and repairs in case of malfunction.
●
If the surface of the AMP3800 enclosure is soiled, wipe with a soft cloth or
use diluted neutral cleaning liquid. Be sure to remove any fluid completely.
Do not use thinner, benzene, alcohol, chemical cloths or bleaching agents as
these may damage the surface of the AMP3800 enclosure. Also avoid using
aerosol insecticides near the unit.
●
If dust should have accumulated on the unit, remove it with stick tape (e.g.
Scotch tape). Make sure not to touch the enclosure with any tools or other
hard parts.
