10 Inputs & Outputs Explained

ANALOG IN

A pair of female XLR 3-31 type connectors used for inputting analog audio signals. These
are balanced inputs with a nominal input level of +4dBm and a maximum input level of
+22dBm. These inputs are intended for use with balanced line level signals, i.e., from a
mixer, synthesizer, drum machine, etc. Microphones, guitars, and equipment with an
output level less than –20dBm must first be connected to a preamplifier, then to the
CBX-D5.
The illustration below shows how an XLR to XLR type cable is wired.

Although balanced, these inputs can be used with unbalanced signals. The diagram below
shows how a balanced XLR to unbalanced phone jack connecting cable should be wired.

ANALOG OUT

Four male XLR 3-32 type connectors used for outputting channels 1 ~ 4 as analog audio.
These are balanced outputs with a nominal output level of 0dBm and a maximum output
level of +17dBm. These could be connected to the inputs of a mixer, amplifier, tape
recorder, DAT recorder , etc.
Cable wiring is the same as the “XLR to XLR cable” shown above. Connection to
unbalanced inputs is also possible by using an XLR to phone jack cable like the one shown
above. Note, however, that a 3-pin female XLR line socket would be used, not a 3-pin male
XLR plug as shown in the illustration.
NOTE: You may buy your XLR connecting cables or you may decide to make your
own, either way always use good quality connectors and cable.
