Model 5110
Mic/Line Input Module
DC Input and Data
A 4-position header, located adjacent to
the analog audio output header, is used
to connect DC power and RS-485 data to
the Model 5110. For details on appropri-
ate mating connectors refer to Appendix B
located at the end of this document.
A source of nominal 12 volts DC, with an
acceptable range of 10 to 18, is required
for Model 5110 operation. The maximum
current is 300 milliamperes at 12 volts DC.
For remote control operation an RS-485
data bus connection from a compatible
Studio Technologies’ remote access mod-
ule is required. Most applications will only
have the DC power connections imple-
mented so these two pins will typically
remain unconnected. Refer to Figure 4
for details.
Digital Audio Output
The Model 5110’s two audio output chan-
nels are available in digital form by way
of a DIN 1.0/2.3-compliant receptacle.
This receptacle is located adjacent to
the analog audio output connector. This
is an AES3-compliant unbalanced 75 ohm
signal that will transport audio, when using
good-quality coaxial cable, several thou-
sands of feet.
The digital audio output signal has a
sample rate of 48 k/sec and a bit depth of
24. The nominal level of the digital au-
dio output is –20 dBFS for Model 5110S
(SMPTE) modules and –18 dBFS for
Model 5110E (EBU) modules.
Mounting
The Model 5110 is intended for mount-
ing into an installation-specific enclosure
or rack panel. Refer to Appendix A for the
unit’s dimensions and mounting screw
locations. Please contact the factory to
discuss mounting options.
