    M214A - Overview

    The Model 214A Announcer's Console is designed to serve as the audio control center for announcers, commentators, and production personnel. This tabletop unit supports applications utilizing the Dante® audio-over-Ethernet media networking technology. The Model 214A is suitable for numerous applications including on-air television sports broadcasting, stadium announcement, and corporate AV. Two pushbutton switches allow the user to control the main and talkback audio output channels. Ease of use, configuration flexibility, and sonic excellence are some of the unit's highlights.

    The Model 214A is compatible with broadcast and audio system environments that use Dante technology. An Ethernet connection with Power-over-Ethernet (PoE) power is all that's required to make the unit part of a sophisticated, networked audio system. Add a microphone and pair of headphones (or a broadcast headset) and the installation is complete. Whether it's the on-air audio, the talkback audio, or the headphone cue feed, superior audio quality is always maintained. Using the STcontroller software application, a range of configuration choices allow the desired operating parameters to be easily selected.

    User Controls and Status Indicators
    Two pushbutton switches, three LED indicators, and three rotary controls provide the user with a clear, easy-to-use interface. One pushbutton switch controls the status of the Dante main transmitter (output) channel. This is the audio channel intended for on-air, announcement, or other primary uses. Two LEDs display the on/off status of the main output channel. A second pushbutton switch controls the status of the talkback Dante transmitter (output) channel. This is the audio signal used to communicate with producers, directors, spotters, or other behind-the-scenes production personnel. A status LED is associated with the talkback pushbutton switch. The two pushbutton switches utilize gold-plated contacts for reliable long-term operation and include backlighting using white LEDs. Three rotary controls allow the user to adjust the content and level of the headphone output channels.

    Microphone Input
    A microphone signal is connected to the Model 214A by way of a standard 3-pin female XLR connector. The unit incorporates a high-performance microphone preamplifier which offers low-noise, low-distortion, and high-headroom amplification over a 19 to 64 dB range. The gain is adjustable in 3-dB steps. The microphone input is compatible with balanced dynamic or condenser microphones. Phantom power is provided and meets the worldwide P48 standard. A dual-color LED indicator serves as an optimization aid when setting the gain of the microphone preamplifier.
