Datasheet

The four pushbutton switches are used to enable the rout-
ing of microphone audio to the Dante transmitter (output)
“talk” audio channels. Configuration choices allow the
operation of the four talk buttons to be optimized to meet
an application’s needs. Their action can be independently
configured, as well as selected to send only voice audio,
or to send both voice audio and an 18 kHz sine wave tone.
This latter capability is specifically provided for supporting
REMI/AT-Home or other specialized applications. A fifth
pushbutton switch, labeled AUX, can be configured to
provide either an “all talk” function or to serve as a call
enable button.
The multipurpose display utilizes eight bi-color LEDs to
provide a range of Model 5304 performance indications.
It can serve as an audio level meter, providing a real-time
indication of the microphone signal as it is sent to one
or more of the active “talk” channels. It will also provide
an indication of the setting of the rotary encoders. The
multipurpose display will also indicate when a configuration
choice has been made or when the Dante identification
function has been received.
Call Signaling Support
Call functions allow Model 5304 users to send and receive
channel-specific visual alert signals. Using 20 kHz tones,
the call signals are sent as part of the audio channels (“in
band”) allowing interoperability between multiple Model
5304 units and other products from Studio Technologies.
This call signaling method is also compatible with ana-
log legacy party-line intercom systems. Call signals can
be useful to indicate to users that they are needed “on
headset” or that they should be actively listening to an
intercom channel. The call function can also be used to
provide real-time cues to production personnel during the
running of live events.
The auxiliary pushbutton switch, located on the right side of
the Model 5304’s front panel, can be configured to serve as
a call button. In this way, any active talk channel will include
a 20 kHz call tone when the auxiliary button is pressed. A
call signal present on any of the four Dante receiver (input)
channels can be detected and displayed. To optimize call
operation for specific applications, a configuration choice
Studio Technologies, Inc. Model 5304 Intercom Station, Issue 3, Page 3
allows the way in which the Model 5304 will light its LED
indicators when call signals are received.
Configuration Flexibility
A highlight of the Model 5304 is its ability to be easily
configured to meet the needs of specific users and ap-
plications. All configuration choices are made using the
STcontroller software application that communicates with
the Model 5304 by way of the unit’s Ethernet network
connection. Configurable parameters include microphone
power and preamplifier gain, sidetone audio operation,
signal present indication, microphone level display, talk
button operation, call indication, remote control inputs,
and headphone monitoring.
The microphone input can be selected for compatibility
with dynamic or electret microphones. The gain of the
microphone preamplifier can be selected from among five
choices. These selections allow compatibility with a variety
of microphones that are part of broadcast and intercom
headsets.
A unique Model 5304 feature is the ability to individually
configure the way that each of the four talk pushbutton
switches function; four choices are available. For standard
intercom user station operation, Push to Talk, Tap to Latch,
or Push to Talk/Tap to Latch operation can be selected. For
situations where only monitoring of an intercom channel
is desired the Disabled mode is available. Configuration
choices allow the two remote control inputs to be individ-
ually assigned to mimic the action of any one of the four
intercom talk buttons or the auxiliary button.
Four audio channels arrive via Dante and are destined for
the 2-channel headphone output. Each input source can be
independently routed to the left headphone channel, right
headphone channel, or both the left and right headphone
channels. This flexibility allows a variety of listening envi-
ronments to be created, including stereo, single-channel
monaural, and dual-channel monaural. As previously
described, a rotary encoder is used to control the audio
level associated with each Dante receiver (input) channel.
In addition, a fifth rotary encoder allows the overall head-
phone level to be controlled.
