Studio Technologies Model 234 Announcers Console

The Model 234 Announcer's Console provides a combination of high-performance audio with an extensive set of user features and configurable resources. The unit is intended for use in demanding broadcast sports, eSports, live event, entertainment, and streaming broadcast applications. With a few simple connections the Model 234 can provide one on-air talent with all the resources they need to support a wide range of applications. The compact, rugged steel enclosure is intended for tabletop use, small enough for use "court-side" or in a crowded booth, yet flexible enough for remote production deployment. The Model 234 supports Dante® audio-over-Ethernet digital media technology with AES67 compatibility for integration into contemporary applications.

The Model 234 can integrate directly into both Dante audio-over-Ethernet and standard analog audio environments. With just a Power-over-Ethernet (PoE) Gigabit network connection, a microphone, and a pair of headphones a complete broadcast on-air position can be created. With the addition of a second Ethernet connection Redundant Dante can be supported. And by using the Model 234's analog microphone output a connection to a microphone-level input on an associated remote I/O interface or audio console can be supported.

With a total of six Dante audio inputs and an integrated sidetone function, users can easily create their desired headphone audio mix. They'll enjoy clear and "click-free" monaural or stereo audio that can only help their on-air performance. Four independent Dante talkback channels allow users to communicate with a variety of support personnel. Among the range of operating capabilities includes the ability to create talent cue (IFB) channels. This was specifically included for REMI/At-Home applications. Provision has been made such that a technician can "customize" the Model 234's hardware. Option kits, purchased separately, can be added to support functions such as multi-pin headset connectors, up to four remote control inputs, and a low-voltage DC tally output.

The Model 234 was designed to meet two main goals: supporting great audio quality and providing an extensive set of configurable features. Using the latest in audio integrated circuits and advanced 32-bit audio processing, the unit's audio performance should meet or exceed that of any audio console, standalone microphone preamplifier, remote I/O interface, or outboard A/D or D/A converter. With over 40 years of professional audio experience, Studio Technologies takes audio performance seriously! And while providing excellent measured specifications is a "must," a device also has to "sound" good before we feel its design is complete.

The amount of flexibility provided in the Model 234 allows it to meet the needs of virtually all on-air announcer applications. And using the Studio Technologies' STcontroller software application makes "customizing" the operation of a Model 234 fast and simple. The unit's ability to handle both day-to-day and specialized situations makes it a unique product in the market. For example, each pushbutton switch and rotary encoder can be independently configured with multiple choices that range from simple to quite advanced. If a Model 234 can't seem to be configured to meet an application's goals please contact Studio Technologies' technical support for an application review.
