The Studio Technologies Model 230 Announcer's Console is a powerful audio control hub for announcers, commentators, and production personnel. Compatible with essentially all broadcast and production audio system environments, this tabletop Model 230 is well suited for on-air television and radio broadcast, and live-event production.

The Studio Technologies Model 230 Announcer's Console is compatible with essentially all broadcast and production audio system environments. Standard connectors are used to interface microphone, headphone, on-air, talkback, IFB, and party-line intercom signals.

Flexible Setup
Three pushbutton switches—Main, Talkback 1, and Talkback 2 —operate under microprocessor control to offer unmatched flexibility and “click-free” audio routing. The Main button controls the main output with operating modes that include push-to-mute (cough), push-to-talk, and latching. The Talkback 1 and Talkback 2 buttons can be configured to route to one of three locations: intercom channel 1, intercom channel 2, or a line-level talkback output. For non-on-air applications a special feature set referred to as “production” mode can be enabled. Simple customization of the button labels ensures the user is presented with an easy-to-use set of controls and indicators.

Superior Audio
Featuring a studio-inspired low-noise/low-distortion preamplifier design, adjustable gain, and 48 volt phantom power, the Studio Technologies Model 230 is compatible with balanced dynamic and condenser microphones. With high output capability and the use of an output transformer expressly designed for professional audio applications, the main output offers broadcast-quality audio as the on-air, stadium announcement, or other primary audio feed.

Powerful Monitoring
The headphone output’s circuitry provides high output levels with very low distortion and noise. The user can monitor up to six external audio sources: IFB channel 1, IFB channel 2, line input 1, line input 2, intercom channel 1, and intercom channel 2. Possible signal sources for the line-level inputs include off-air receivers, wireless IFB systems, and audio consoles. The Studio Technologies Model 230’s intercom interface is compatible with standard party-line intercom systems from manufacturers such as RTS™ and Clear-Com®. Each source can be individually assigned to the left, right, or both channels of the binaural headphone output. Two rotary controls allow the user to adjust the headphone output levels. Studio Technologies’ unique “auto-terminate” feature ensures talkback-to-intercom “squeal” will never occur in the headphone output if an intercom line is disconnected.

Speedy Configuration
The Studio Technologies Model 230 configurations are made using DIP-type switches and trim potentiometers that are accessible via the bottom of the enclosure. No disassembly is required. An included security plate attaches to the bottom of the enclosure to limit access.

Installer Friendly
The Studio Technologies Model 230 can be powered by the IFB input, intercom interface, or the supplied external 24 volt DC source. Regardless of the power source used, the console is always fully operational including 48 volt phantom power. Audio inputs and outputs utilize industry-standard 3-pin XLR-type connections. Three spare connector locations are available on the Studio Technologies Model 230’s back panel. Factory-available assemblies and card kits allow a technician to customize these spare locations to accept a 6- or 7-pin XLR-type headset or to bring the auxiliary relay contacts to an XLR connector. Additional card kits include direct microphone output, second line-level talkback output, and remote switch input.
