{"product_id":"sonifex-cm-tb8-8-channel-talkback-control-unit","title":"Sonifex CM-TB8 | 8 Channel Talkback Control Unit","description":"\u003cp\u003eThe CM-TB8 is a powerful and highly flexible self contained communications unit allowing multiple 4-wires and IFBs within a single 1U rack space. It offers easy connection to any industry standard talkback system including the Sonifex CM-TLL line listen unit, the CM-BHA and CM-BH4W belt-packs plus the CM-CU1 and CM-CU21 commentator units. The CM-TB8 8 Channel Talkback Control Unit is ideal in an OB truck or small studio. The unit has individual connections for both a headset on 5 pin XLR and microphone\/headphones on XLR\/stereo TRS jack, with the current selection indicated on the front panel. The gain setting for each input type can be individually set between +6dB and +68dB allowing for a wide range of microphone types and +48V phantom power is also available. Small talk level adjustments can be made quickly, using the front panel rotary control with a maximum adjustment range of ±12dB. This adjustment can be disabled if required to stop inadvertent changes. A level limiter automatically adjusts the microphone gain if the signal level exceeds a preset level, and the current talk level is indicated on the front panel when it exceeds 0dB and +8dB. A separate output on the rear panel provides a balanced, gain adjusted and level limited microphone signal on 3 pin XLR.\u003c\/p\u003e\u003ch3\u003eProduct
