Studio Technologies MODEL-210

The Model 210 Announcer's Console is an audio control "hub" for announcers, commentators, and production personnel. Compatible with essentially all broadcast and production audio system environments, the tabletop unit is often used for on-air sports broadcasting.

Flexible Setup
Two pushbutton switches—Main and Talkback—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 button controls a dedicated line-level output to provide talent-oriented cue signals to production personnel. 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 210 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 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 either or both IFB channels. 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.
