Connections
Connecting Balanced Sources
Use high-quality three-conductor cable for
balanced connections, such as Star Quad by
Belden, Canare, Mogami, etc. The better the shield,
the better the audio signal is protected from
induced EMI and RFI.
Note: With screw-down connectors, it's best to
use stranded wire that is not tinned. Solder can
"flow" under the pressure of the screw-down
terminal and cause the connection to become
loose.
To connect a balanced mic or line-level signal:
Strip the wire back about 1/4" inch, insert the
wire as far as it will go into the appropriate hole in
the supplied Phoenix-type connector, and tighten
down the screw with a small slot-head screwdriver.
It is recommended that you use 20 or 22 gauge
wire with the Phoenix-type connectors. The
connectors are wired as follows:
Pin 1 = Ground (Shield)
Pin 2 = Hot (+)
Pin 3 = Cold (–)

Balanced Connection (Line Input Shown)
Note: To connect to the
MIC
inputs, turn the
connector upside-down relative to the
LINE
input
connector. Double check the wiring with the wiring
graphics indicated on the rear panel.
Connecting Unbalanced Sources
It may be necessary to connect a 2-conductor
unbalanced input to a balanced input on the DX8.
To connect an unbalanced line-level signal:
Follow the instructions for connecting a balanced
line-level signal above, but wire the connector as
follows:
Pin 1 = Ground (Shield)
Pin 2 = Hot (+)
Pin 3 = Ground

Connecting the DIRECT OUTPUTS
This is a 15-pin D-Sub connector. The signals on
the
DIRECT OUTPUT
are unbalanced. Use shielded,
twisted pairs for the
DIRECT OUTPUT
cable to ensure
the best rejection of external noise (EMI and RFI).
The

Connecting the RECORD Outputs
These are RCA-type unbalanced connectors. Use
high-quality shielded cable with RCA-type plugs for
these connections.
Connecting the Bus A and B OUTPUTS
These are 3-pin Phoenix-type connectors that
provide a balanced line-level output signal from Bus
A and Bus B. Use high-quality, three-conductor
shielded cable for these connections.
