    AB-120 - Overview

    Designed for sports, live-event broadcasting and voice-over work!

    The ClearCom Encore AB-120 Announcer Console is a compact desktop unit designed specifically for sports, live-event broadcasting and voice-over work. The ultimate broadcast quality tool for announcers and commentators, the AB-120 integrates all the inputs, outputs and controls necessary at the announce position, including intercom "Talkback", IFB and a silent "Mic Mute" button that provides noise-free "Cough" and "Mic on/off" switching. The "no compromise" mic preamp ensures the highest broadcast quality audio from the announcer's microphone. A high-output stereo headphone amplifier guarantees talent can always hear both program audio and "cues" from the control room, even in the loudest of live sporting environments. The AB-120 plugs into and draws power directly from most intercom and IFB systems, permitting an announce position to be located virtually anywhere, regardless of available AC power. Extremely flexible, the console is easily configured for any combination of audio sources, microphones, headsets or intercom systems, ensuring quality audio and powerful communications.

    On-Air Broadcast Quality
    Designed as part of the Encore Analog Partyline Intercom System the AB-120 can be used with any professional broadcast headset or separate microphone/headphone and will always delivers broadcast quality line-level audio. A Jensen ™ output transformer delivers up to -10dBu (with 20dB of headroom) into 600 Ohms, providing a properly balanced signal and reduces the possibility of ground loops, buzz or hum. When locally powered, the AB-120 also provides phantom power for headsets with condenser microphones.

    Intercom Communications
    Pressing the "Talkback" key momentarily switches the microphone output from "on-air" to the intercom channel. The console can be configured so that intercom audio can be heard in the left ear, right ear or both, helping the talent to instantly identify the source. The AB-120 connects to almost any professional audio system.

    Please Note! This item is just one component of a larger system. Please refer to the diagram for ideas and recommendations for your Clear-Com intercom system. Diagram shown is a recommendation for a small broadcaster with partyline systems.
