The Model 230 Announcer's Console is designed to serve as the audio control "hub" for announcers, commentators, and production personnel. The tabletop unit is suited for numerous applications including on-air television and radio broadcasting. The Model 230 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.
Whether it's the mic preamplifier, audio switching, talkback signals, intercom interfacing, or headphone cue feed, superior audio quality is maintained throughout. A microprocessor provides the Model 230's logic power, allowing precise control of the unit's operation. With extensive flexibility built in, creating the desired operating configuration is a simple matter. While the operating features of the unit can be carefully tailored, the user is presented with an easy-to-use set of controls and indicators. A wide range of resources, great performance, and simplicity during use—these are the hallmarks of the Model 230.
A truly next-generation product, exhaustive research into the needs and desires of field production personnel was integral to the Model 230's creation. Providing a veritable "tool kit" of features, the unit supports a wide variety of applications that include on-air television and radio broadcasting, stadium announcement, and simultaneous interpretation.
Microphone Input
A high-performance microphone preamplifier circuit provides low-noise/low-distortion amplification over a 20 to 60 dB gain range. The gain is adjustable in 10 dB steps. The input is compatible with balanced dynamic and condenser microphones. The microphone power source is 48 V nominal and meets the worldwide P48 phantom power standard. The preamplifier's gain can also be set for 0 dB, allowing a line-level audio signal to be connected. This could provide useful in special applications such as when an external preamp or mic processor is being used.
An LED indicator serves as an aid for optimizing the preamplifier's gain setting. The output of the microphone preamplifier is used by the main output as well as being routed to the compressor circuit that supports the talkback functions.
Main Output
The Model 230 provides a main output that is designed to serve as the on-air, stadium announcement, or other primary audio feed. Nominally –2 dBu, it is designed as a fully professional interface with high output capability, low distortion, and low noise. The output circuitry features a high-performance output transformer expressly designed for use in professional audio applications.
Talkback Functions
The talkback functions are intended to provide personnel associated with production trucks, control rooms, live-performance, and sports venues with talent-originated cue signals. The Model 230 contains two pushbutton switches that control the talkback functions. Each button can be configured to allow talkback audio to be routed to one of three locations: intercom channel 1, intercom channel 2, or a line-level talkback output. The line-level talkback output is transformer-coupled with a +4 dBu nominal signal level. It contains resistors in series with the output connector, allowing line-level talkback outputs from multiple units to be directly "summed."
For non-on-air applications, the Model 230 can be placed in its "production" mode. This software-based mode allows the main output to be used as an additional talkback output. This feature makes the unit even more powerful when used in live-event applications, such as serving as a master console for an orchestra conductor or production director. With this flexibility, the exact needs of many specific applications can easily be met. And, of course, whatever configuration is selected the audio quality will be excellent.
Dynamic Range Control
To enhance the Model 230's talkback functions, a studio-quality compressor circuit is provided to control the dynamic range of the signal coming from the microphone preamplifier. Far from a simple "clipper," the circuit utilizes a sophisticated laser-trimmed voltage-controlled-amplifier (VCA) integrated circuit for quiet, low-distortion level control. The signal from the compressor is used by the talkback functions. This ensures that talkback audio signals remain clear and intelligible under all real-world conditions. In addition, dynamic range control is especially important when talkback signals are being routed to party-line intercom channels.
User Controls and Status Indicators
Three pushbutton switches, four LED indicators, and two rotary controls provide the user with a clear, easy-to-use interface. One pushbutton switch controls the status of the main output. This is the audio output intended for on-air, announcement, or other primary uses. Two LEDs display the on/off status of the main output. Two additional pushbutton switches control the status of the talkback functions. These functions create the audio cue signals used to communicate with producers, directors, "spotters," or other behind-the scenes.
