Studio Technologies Model 233 Announcer's ConsoleThe Model 233 Announcer's Console is the premier audio control "hub" for announcers, commentators, and live-event production personnel. Compatible with essentially all broadcast and production audio system environments, the tabletop unit is ideally suited for numerous applications including stadium announce, on-air television, and radio broadcasting.Key Features Microphone preamp with selectable gain and 48 volt phantom power Two line-level inputs Three pushbutton switches offer programmable "click-free" audio path control Transformer-balanced main output Two line-level talkback outputs Dual-channel intercom interface with "auto-terminate" Stereo headphone monitoring of selectable sources and integrated sidetone Three rotary headphone output level controls for external sources and sidetone Microcontroller-directed audio routing Tally status output and auxiliary relay contacts Powered by intercom or by supplied external DC source All configuration switches and trim potentiometers accessible via the bottom of the enclosure Flexible SetupThree 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 control dedicated line-level outputs to provide talent-originated cue signals to production personnel. The Talkback buttons can also be configured to send audio to the dual-channel intercom interface. "Stadium announce" mode and "production" mode enable special feature sets for these applications. Simple customization of the button labels ensures the user is presented with an easy-to-use set of controls and indicators.Superior AudioFeaturing a studio-inspired low-noise/low-distortion preamplifier design, adjustable gain, and 48 volt phantom power, the Model 233 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 stadium announcement, on-air, or other primary audio feed.Powerful MonitoringThe headphone output's circuitry provides high output levels with very low distortion and noise. The user can monitor up to four external audio sources: 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 233's intercom interface is compatible with standard party-line intercom systems from manufacturers such as RTS and Clear-Com. If desired, broadcast IFB can also be connected to the intercom input. Each source can be individually assigned to the left, right, or both channels of the binaural headphone output. Three rotary controls allow the user to adjust the levels of the externally connected sources and the user's sidetone. 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 ConfigurationModel 233 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 panel attaches to the bottom of the enclosure to limit access.Installer FriendlyThe Model 233 can be powered by the 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. To meet the exact needs of specific applications, three spare connector locations are available on the Model 233'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 or tally output to an XLR connector. Additional card kits, available from Studio Technologies, include direct microphone output and remote switch input.
