When making a digital
connection between the U-8
and the CD player, MD
player, DAT player, or the
like, connect the digital
output from the CD, MD,
or DAT player to the
Digital Input connector on
the U-8. For more
information, refer to
“

Connection

External Equipment
” in
the U-8 Technical Guide.
Be careful of loop connections
fig.04-06a.e
When the U-8 is connected as shown in the above diagram to a device that passes the input
sound through to its output (an MD/DAT/CD-R that is recording), the U-8 and that device
will form a loop that can cause oscillation, producing an unexpectedly loud sound.
This type of connection can cause malfunction and damage to speakers and other equipment;
take care to avoid these conditions.
In addition to the above figure, take a moment now to check your connections for the
following conditions.
• Could there be a looped connection between the analog and digital realms?
• Has any looped connection resulted from insertion of a mixer or other piece of equipment
between the devices?
