SONIFEX CM-CU21 Commentatator Unit

SONIFEX-CM-CU21-Commentator-Unit

The new AVN (Audio Video Network) products are designed to operate over a standard CAT5 infrastructure, offering Dante®, AES67 AoIP compatibility and simple web server configuration.

AVN-CU2 Configurable Dante Commentary Unit for 2 Commentators

The AVN-CU2 takes a new approach to provide a multi-purpose configurable tool for commentary teams. Its power lies in the impressive mix engine which overlays the usual Dante® Controller settings. Once Dante® flows have been made, inputs and outputs can be mixed freely to AoIP or physical inputs and outputs, controlled using the programmable buttons and rotary encoders, which control the gain and pan of inputs, outputs or cross-points, allowing total flexibility for different situations. It can be used in any number of different commentary situations, controlled manually or remotely and controls can be ‘locked down’ so that they can’t be tampered with or altered, to guarantee reliable operation.

If you’re putting audio onto your Dante® network, make it the best audio quality that it can be, by using the Sonifex DIO audiophile Dante® interfaces. These simple plug and play audio interfaces provide a convenient and elegant method of connecting legacy analogue and digital audio equipment to the Dante AoIP audio network.

Telephone Hybrids

Sonifex telephone hybrids are some of the best sounding hybrids in the world with analogue, digital, portable, GSM & HD Voice hybrids available.

Analogue Telephone Hybrids
The analogue HY-03 telephone hybrid sets the standard as an excellent value, high quality telephone hybrid. It is fully automatic, with automatic signal limiting, automatic call answering and both local and remote line hold switching.

Digital Telephone Hybrids
The digital DHY-04 telephone hybrid is probably the best performing digital hybrid in the world, with simply stunning line balance rejection figures – 76dB typically. It is fully automatic together with echo cancellation, conferencing, front panel input and output gain controls and front panel LED metering of receive and send signals. Additionally it has auto-sensing AES/EBU or analogue XLR I/O, an Ethernet port for remote configuration and remote control, SNMP and DTMF dial up recognition.

GSM Hybrid
The DHY-04G is a digital GSM hybrid which has all features of the DHY-04 but uses a 2G cellular connection instead of an analogue POTS line. Ideal for studios in remote locations and with the outstanding performance of the DHY-04.

HD Voice Hybrid
The DHY-04HD HD Voice Hybrid is used on a 3G or GSM cellular phone network instead of a telephone (POTS) line. The DHY- 04HD can accept a SIM card and by connecting a GSM antenna, it can receive and make high quality broadcast calls over the cellular network, converting the 3G/GSM call to the 4 wire audio signal to/from a mixer. The cellular module is quad-band GSM and 5 band UMTS/ HSPA+, to take/make calls on any 2G/GSM, or 3G network.

Portable Telephone Hybrids
The CM-TBU line-powered telephone balance unit is a basic hybrid for 2-way talkback purposes and the CM-TLL provides a low-loss interface to receive audio from a telephone line.

Audio Logging
The Net-Log has been specifically designed for long-term recording and archival.

It uses a dedicated hardware recording platform with a simple network connection for audio playback.

Audio & IP Stream Logging

Flashlog 8 is configurable, ultra powerful multi-channel logging software. Using the Sonifex sound & radio capture cards, IP based line inputs and internet radio streams, Flashlog can be used to continuously log up to 2 years of radio broadcasts or audio.
