DA-14 Operation and Application
Because of the fundamental simplicity of the DA-14, there are no
operating procedures apart from applying an input signal, connecting
outputs, and applying power. There are no level adjustments, as the
unit puts out a standard level. In addition, no reference is required as
the DA-14 locks to the AES input signal.
In addition to basic distribution, two additional DA-14 applications
should be noted:
•
S/PDIF to AES conversion
Because the DA-14 can operate in a range as low as 165mv, it
can be used as an S/PDIF to AES converter. By using an
S/PDIF adapter on your S/PDIF source and connecting it to the
DA-14’s BNC input, you can achieve full level AES output
(times four), provided that the source output is above the
165mv threshold. Note that S/PDIF adapters (BNC to RCA
Phono) are readily available at consumer electronics stores.
•
Multiple output capability
To configure two or more DA-14 units for multiple outputs
(beyond the basic four), remove the terminating jumpers, place
a BNC “T” on the input connector, and bridge as many DA-14s
as required to produce the required number of outputs. In this
configuration, ensure that the last DA-14 in the chain is
terminated — either internally, or externally with a 75-ohm
terminator on the BNC “T” connector.
Refer to the following “ DA-14 Interconnection ” section for an
illustration of this “multiple output” configuration. Refer to the
DA-14 Internal Jumpers ” section for information on
changing input termination.
