Studio Technologies Model 205 Announcer's Console

Product Code: ST-M205

Key Features

The Model 205 Announcer's Console offers a unique combination of analog and digital audio resources for use in broadcast sports, eSports, live event, entertainment, and streaming broadcast applications. The unit is housed in a compact, rugged steel enclosure that’s intended for table-top use. Calling the Model 205 "cute" or "cool" would be accurate; its nicely proportioned but diminutive size makes it ideal for use in space-constrained locations. The Model 205 supports Dante® audio-over-Ethernet digital media technology with AES67 compatibility for integration into contemporary applications. The unit is extremely simple to deploy, is "pro" quality throughout, and provides an intuitive user experience. The Model 205's audio quality is excellent, with low distortion, low noise, and ample headroom. Careful circuit design and rugged components ensure long, reliable operation.

Studio Technologies Model 205 Announcers Console

The Model 205 integrates directly into both Dante audio-over-Ethernet and standard analog audio environments. With just a Power-over-Ethernet (PoE) connection, a microphone, and a pair of headphones or an earpiece, a complete broadcast on-air position can be created. And by using the Model 205's microphone output a direct connection to an analog microphone-level input on an associated camera, remote I/O interface, or audio console can be supported. Two remote control inputs allow external switches or contact closures to activate the main and/or talkback button functions.

Model 205 operating features are configured using the STcontroller personal computer software application. An extensive set of parametres allows the unit's functions to be tailored to meet the needs of many applications. STcontroller, compatible with version 7 and later of the Windows operating system, is a fast and simple means of confirming and revising the unit's operating parametres.

Applications

The Model 205 on its own can provide an "all-Dante" solution for one on-air talent location. A wide range of applications can be supported, including sports and entertainment TV and radio events, streaming broadcasts, corporate and government AV installations, and post-production facilities. The unit's small size makes it ideal for live-sports applications, such as basketball, where physical space for personnel is very limited. Four Dante receiver (audio input) channels supply the user with their talent cue (IFB) signals. Should the cue signal be "mix-minus" an integrated sidetone function can provide the user with a microphone confidence signal. Three Dante audio output channels, one designated as main and two as talkback, are routed via an associated local-area network (LAN) to inputs on Dante-compatible devices. Three pushbutton switches, main and two talkback, provide the user with direct control over audio routing. The audio switching is performed in the digital domain and is virtually "click-free."

By providing the main audio signal in two forms, Dante digital audio and analog microphone level, the Model 205 makes integration into a wide range of on-air environments easy to accomplish. And with the two talkback audio channels available as Dante output channels, routing to inputs on a variety of devices, such as matrix intercom systems, audio consoles, and monitor loudspeaker systems, is simple and flexible.

Some applications may benefit from not utilizing the Model 205'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 purposes 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 inputs on an audio console or console-related I/O unit. Supporting these scenarios is not a problem as the Model 205 supplies a microphone output connection that's specifically intended for this purpose. Simply connect the unit's microphone output connection 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 205'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 205 is simple. An etherCON® RJ45 jack is used to interconnect with a standard twisted-pair Ethernet port associated with a PoE-enabled network switch. This connection provides both power and bidirectional 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 condenser 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 205's remote control inputs to allow activation of button functions.
