A) AC Port Connect an IEC standard 3-prong AC power cord here. The center post is chassis ground.
B) Analog Audio Inputs
The Eclipse's analog inputs accept either unbalanced 1/4-inch con-
nectors or balanced XLR connectors. Pin #1 is ground, pin #2 is posi-
tive phase (hot), and pin #3 is negative phase (cold). To "unbalance"
the XLR jack, use both pins #1 and #3 as ground and use pin #2 as
"hot." If pin #1 and/or pin #3 are unconnected, you will get more
noise and hum than signal! You can connect a guitar to the 1/4-inch
inputs, but the input level will need to be boosted (
GAIN}
).
C) XLR Analog Audio Outputs
These analog outputs accept balanced XLR connectors. The same pin
layout and "ungrounding" procedure described above applies here as
well.
D) 1/4-inch Analog Audio Outputs
These analog outputs accept balanced 1/4-inch connectors. The sleeve
is ground, the ring is negative phase (cold), and the tip is positive
phase (hot). Using an unbalanced 1/4-inch connector will reduce the
output by 6dB.
E) XLR Digital Interface
Use these connectors to connect professional digital audio gear to the Eclipse. These cables
are differential with a shielded twisted pair. To select the XLR input as the digital source,

We recommend the use of purpose-manufactured Digital Audio cables, which have low capacitance and con-
trolled impedance for carrying AES/EBU signals. Ordinary microphone cables will usually work at 48kHz,
but may reduce range and add jitter and distortion to the signal. It is unlikely that microphone cable will
prove satisfactory for 96kHz operation.  see page 24
