The 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, the tabletop unit is well suited for on-air television and radio broadcast, and live-event production.

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 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 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.
