With both 4-wire analogue inputs and outputs, as well as AoIP network audio connectivity, the AVN-TB units can be used with existing legacy 4-wire systems and with new AES67 AoIP networked audio infrastructure. Additionally, all audio is at 48kHz sample rate, meaning that it’s broadcast quality audio as standard. RAVENNA (of which AES67 is a subset) allows for the distribution of audio across a network. The AVN range use RAVENNA as the communication method providing compatibility with other AES67 systems.\u003c\/p\u003e\u003ch3\u003eProduct Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e10

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

Its sturdy construction and features make it suitable for use in a wide variety of environments. Sonifex has a solution for those situations where a separate commentary unit is required, or where ISDN\/pots communications, or a complex digital solution aren’t needed. The CM-CU21 stand alone commentator unit is a rugged, reliable solution which includes all the features needed to ensure 2 commentators can provide their expertise, together with a guest position or co-commentator. The guest position can alternatively be used as a line-level input for international sound or special effects such as the sounds of the action and spectators. Each of the 3 announcer positions has an individual output, with two additional outputs providing a mix of all active commentary channels.\u003c\/p\u003e\u003ch3\u003eProduct Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e2 Commentator positions plus a guest position, each with individual outputs; plus 2 mix outputs.\u003c\/li\u003e\n\u003cli\u003eTalkback outputs selectable by the two main commentators, with built in limiter \u0026amp; adjustable gain.\u003c\/li\u003e\n\u003cli\u003e4 Return audio circuits that are routed to headphones along with all the commentator inputs.

This uses audio transformers at its input and output, providing galvanic isolation from outside interference, ensuring your communications are loud and clear, every time. In 4-wire mode, the unit acts as a 2-way intercom, with input audio routed to the headset earpiece, and microphone audio is routed to the output upon pressing the talk button. The output level is maintained at +2dBu peak level by a built-in AGC. In IFB mode, the input audio is routed to the output, and is interrupted by the microphone signal when the talk switch is pressed. The talk switch can easily be converted from momentary to latching operation to suit your application. A low battery warning LED flashes when the 9V PP3 battery has depleted to 6V, giving plenty of notice to swap the battery. In addition, the CM-BH4W automatically switches off when the headset jack is removed, and the low power circuitry gives up to 150 hours use from a single alkaline 9V PP3 battery.

The CM-BHA has an adjustable limiter to protect the listener from excessive levels indicated by a blue LED. The limiter is only enabled when an earpiece or headphones are used, and when it is activated by the toggle switch.
