The use of Dante AoIP means that inputs and outputs can be added as required (up to a max of 16 per unit). Any physical input can be combined, mixed, and routed to any output, giving you complete flexibility to create fully customisable cross-points. Additionally you can choose which of those cross-points need to be controlled by the use of rotary encoders. Using a built-in web GUI, up to 24 encoders (4 nameable pages of 6 rotary encoders) can be assigned to inputs, outputs or cross-points. Encoders can control the volume and pan of headphones and volume of the assigned inputs, outputs or cross-points. Each rotary encoder has a separate colour-coded meter section showing the channel name, detailed level metering and left\/right panning on a bright daylight reading display. The colours are configurable to quickly identify particular source groups, so headphone source selection becomes intuitive.\u003c\/p\u003e\u003ch3\u003eProduct

The use of Dante AoIP means that inputs and outputs can be added as required (up to a max of 16 per unit). Any physical input can be combined, mixed, and routed to any output, giving you complete flexibility to create fully customisable cross-points. Additionally you can choose which of those cross-points need to be controlled by the use of rotary encoders. Using a built-in web GUI, up to 48 encoders (8 nameable pages of 6 rotary encoders) can be assigned to inputs, outputs or cross-points. Encoders can control the volume and pan of headphones and volume of the assigned inputs, outputs or cross-points. Each rotary encoder has a separate colour-coded meter section showing the channel name, detailed level metering and left\/right panning on a bright daylight reading display. The colours are configurable to quickly identify particular source groups, so headphone source selection becomes intuitive.\u003c\/p\u003e\u003ch3\u003eProduct

The use of RAVENNA\/AES67 AoIP means that inputs and outputs can be added as required (up to a max of 16 per unit). Any physical input can be combined, mixed, and routed to any output, giving you complete flexibility to create fully customisable cross-points. Additionally you can choose which of those cross-points need to be controlled by the use of rotary encoders. Using a built-in web GUI, up to 24 encoders (4 nameable pages of 6 rotary encoders) can be assigned to inputs, outputs or cross-points. Encoders can control the volume and pan of headphones and volume of the assigned inputs, outputs or cross-points. Each rotary encoder has a separate colour-coded meter section showing the channel name, detailed level metering and left\/right panning on a bright daylight reading display.

The use of RAVENNA\/AES67 AoIP means that inputs and outputs can be added as required (up to a max of 16 per unit). Any physical input can be combined, mixed, and routed to any output, giving you complete flexibility to create fully customisable cross-points. Additionally you can choose which of those cross-points need to be controlled by the use of rotary encoders. Using a built-in web GUI, up to 48 encoders (8 nameable pages of 6 rotary encoders) can be assigned to inputs, outputs or cross-points. Encoders can control the volume and pan of headphones and volume of the assigned inputs, outputs or cross-points. Each rotary encoder has a separate colour-coded meter section showing the channel name, detailed level metering and left\/right panning on a bright daylight reading display. The colours are configurable to quickly identify particular source groups, so headphone source selection becomes intuitive.\u003c\/p\u003e\u003ch3\u003eProduct

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

applications. It provides a fully featured commentator position and a line-level input. The unit has an individual commentator output, with an additional output providing a mix of commentator and line input audio. A limit indicator on the main panel shows when the adjustable limiter on the main output is active, and a bright 21 segment LED PPM meter, which can be disabled, shows the main output level. The line input can be configured to remain present at the mix output even if the commentator is off air, making it useful for routing crowd effects or pre-recorded material to the programme feed.

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.

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.

The CM-BHA has an adjustable limiter to protect the listener from excessive levels indicated by a blue LED.

The high degree of separation between send and receive signals makes it suitable for use in telephone IFB (interrupted foldback) applications and the high drive capacity at the 4-wire output enables a presenter’s earpiece to be connected directly to the unit without an external amplifier. This extremely compact unit is powered from the telephone line and provides an interface to a 4-wire circuit with separate level control of send and receive signals. Optimum rejection of the input signal on the 4-wire output is achieved in a bridge circuit by adjusting three elements (NULL, R-BAL and C-BAL) via potentiometers which simulate the complex line impedance. This can be used to compensate for local line variations or to adapt to the telephone systems of other countries, where line characteristics may differ.\u003c\/p\u003e\u003ch3\u003eProduct Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIsolated, full-duplex 4-wire interface to direct non-digital telephone exchange lines.\u003c\/li\u003e\n\u003cli\u003eLine powered, requiring no battery or external power.\u003c\/li\u003e\n\u003cli\u003eSimple optimization of sidetone rejection with any country’s telephone system.\u003c\/li\u003e\n\u003cli\u003eLEDs indicating ‘Ring’, ‘Line Hold’ and ‘Limit’ conditions.\u003c\/li\u003e\n\u003cli\u003eInput level control with line-sensing limiter and limit indicator.\u003c\/li\u003e\n\u003cli\u003eHigh drive output with level control for direct feed to presenter’s earpiece, etc.\u003c\/li\u003e\n\u003cli\u003eLoop-through RJ11 line sockets provide universal connection to line and telephone set.\u003c\/li\u003e\n\u003cli\u003eConnection to the telephone set is maintained while the unit is in use.\u003c\/li\u003e\n\u003cli\u003eSmall, rugged aluminium case.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTypical Applications\u003c\/h3\u003e\u003cp\u003eTalkback applications, e.g. to get cue feed to a remote presenter from a distant studio, hospital\/community radio talkshows, house of worship remote listen \u0026amp;

The line-powered unit is compatible with all analogue direct exchange lines and includes an LED indication of incoming calls. The unit is intended to be used with an earpiece amplifier to receive an audio feed by telephone from a studio. The line and telephone set are connected to the unit via the RJ11 connectors in order to make an outgoing call. A telephone may not be required if calls are only incoming, because telephone line ringing is indicated by a flashing LED built into the unit.
