Studio Technologies Model 210 Announcers Console

Product Code: ST-M210

Key Features

The Model 210 Announcer's Console is designed to serve as the audio control centre for announcers, commentators, and production talent. The tabletop unit is suited for numerous applications including on-air television sports broadcasting. The Model 210 integrates all on-air, talkback, and cue audio signal routing into one compact system. Ease of use, configuration flexibility, and sonic excellence are some of the unit's highlights.

The Model 210 is compatible with most broadcast and audio system environments. Standard connectors are used to interface microphone, headphone, talkback, and IFB signals. Whether it's microphone switching, talkback output, or headphone cue feed, superior audio quality is maintained. A microprocessor provides the Model 210's logic power, allowing exacting control of the unit's operation.

Studio Technologies Model 210 Announcers Console

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 or 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 prove 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 setting of the preamplifier's gain. 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 function.

Main and Talkback Outputs

The Model 210 provides one main and one talkback output. The main output is designed to serve as the on-air, stadium announcement, or other primary audio feed. With a nominal level of –2 dBu, it is designed as a fully professional interface with high output capability, low distortion, and low noise. It features a high-quality transformer expressly designed for driving long broad- cast cable runs. The talkback output is intended to provide production trucks, control rooms, or support personnel with a talent-originated cue signal. The talkback output is transformer-coupled with a 4 dBu nominal signal level. It contains resistors in series with its output connections, allowing the talkback output from multiple units to be directly summed (combined).

For non-on-air applications, a special Model 210 feature can be enabled, placing the unit in a "production" mode. This allows the main output to be used as a second talkback output. In this configuration the unit can be even more powerful when used in a live event application, such as serving as a master console for a production director.

Dynamic Range Control

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.

User Controls and Status Indicators

Two pushbutton switches, three 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. A second pushbutton switch controls the status of the talkback output. This is the audio output used to communicate with producers, directors, spotters, or other behind-the-scenes production personnel. A status LED is associated with the talkback button. Two rotary controls allow the user to adjust the level of the headphone output.

Flexibility

A large part of the Model 210's unique power is the ability to configure the operation of the main output and talkback functions. To meet the needs of the many specific broadcast and production applications, a variety of button operating modes is available. The main output button can be selected to operate from among four modes. In the "push-to-mute" mode the button performs a momentary mute of the main output. In this way a "cough" button function is created, something typically required for television sports broadcasting. In the "push-to-talk" mode the button provides a momentary active function for the main output. This mode would be appropriate for applications such as stadium announcement. An alternate action "latching" configuration allows the button to enable or disable the main output as desired. This is useful in radio broadcasting, announce-booth, or voice-over applications. The fourth mode provides a hybrid function, supporting both push-to-talk and tap-to-enable/ tap-to-disable operation. This operation is similar to that found in many broadcast intercom system user stations.

The button associated with the talkback function can be configured to operate from either of two modes. One of the modes supports a "push-to-talk" function. This is typically used for on-air broadcast applications. The other mode provides a hybrid function, the operation of which is discussed in the previous paragraph. The hybrid mode is especially useful when the Model 210 is used in a production-support application.

IFB Input

A broadcast-standard "wet" (DC with audio) IFB circuit can be directly connected to the Model 210's IFB input.
