Studio Technologies, Inc. Model 204 Announcer’s Console, Issue 1, Page 2
By providing the main audio signal in two forms, Dante digital
audio and analog microphone level, the Model 204 makes
integration into a wide range of on-air environments easy to
accomplish. The talkback audio channel is available as a Dante
output channel which makes routing to an input on a variety of
devices, such as matrix intercom systems, audio consoles, and
monitor loudspeaker systems, simple and flexible.
Some applications may benefit from not utilizing the Model 204’s
Dante main output channel. This typically won’t be an issue of
inadequate audio quality but rather a need to match work-flow
requirements. For example, for lip-sync or transmission pur-
poses it may be optimal to have the on-air audio transported
as an embedded signal along with the associated camera video.
Alternately, all on-air audio sources may need to connect to in
-
puts on an audio console or console-related I/O unit. Supporting
these scenarios is not a problem as the Model 204 supplies a
microphone output connection that’s specifically intended for
this purpose. Simply connect the unit’s microphone output con-
nection to the desired analog input, such as the mic/line input
on an ENG-style camera—that’s it!
The circuitry associated with the Model 204’s analog microphone
output is very simple, essentially a passive path that routes a
signal connected to the microphone input connector directly to
the microphone output connector. A solid-state circuit, in series
with the mic in-to-mic out path, allows muting of the signal on the
microphone output connector whenever the Dante main output
channel is muted. Having both the Dante main output and the
microphone outputs work in tandem can be a valuable resource,
allowing one to serve as the primary on-air signal source while
the other serves as the backup.
Setup and Operation
Set up, configuration, and operation of the Model 204 is simple.
An etherCON® RJ45 jack is used to interconnect with a stan
-
dard twisted-pair Ethernet port associated with a PoE-enabled
network switch. This connection provides both power and bidi
-
rectional digital audio. A broadcast headset or handheld (“stick”)
microphone can be directly connected to the unit’s 3-pin XLR mic
input connector. The input is compatible with dynamic or con
-
denser microphones. The integrated P48 phantom power source
provides support for a wide range of condenser microphones. A
3-pin XLR microphone output connector provides a “direct mic
out” function for integration with microphone inputs on related
devices. Stereo headphones, the headphone connections from
a stereo or monaural headset, or even a monaural earpiece can
be connected to the phones output jack. External switches or
contact closures can be connected to the Model 204’s remote
control inputs to allow activation of the main and talkback but
-
ton functions. The STcontroller software application is used to
configure the wide range of Model 204 operating parameters.
This allows the unit’s performance to be optimized to meet the
needs of specific applications.
The user is presented with two pushbutton switches and three
push-in/push-out rotary level potentiometers. This makes it
easy to control the status of the main and talkback outputs as
well as adjusting the signals that are sent to the headphone
channels.
