Unity Intercom provides a low-cost, novel and reliable IP intercom system that allows you to use your existing smartphones as Intercom stations.

Unity works by connecting over Wi-Fi or via a mobile network to a “Unity Server” providing Talk and Listen on multiple independent channels, as well as an independent programme audio feed. The free apps downloaded onto iOS or Android devices convert smartphones into wireless intercom stations from which the Talk and Listen channels can be selected. It works in both 2-wire (broadcast) and 4-wire (user to user) mode with a large Push-To-Talk button that can be momentary or latched. Unity can also display camera “On-Air” Tally and integrates with hard-wired communication systems like Clear-Com or RTS, letting you use Unity as a wireless station.

For the mobile intercom stations, the appropriate iOS or Android Unity app is downloaded (free), Listen and Talk channels are selected – then simply Push-to-Talk (PTT). The smartphones can be equipped with headsets – either cabled or Bluetooth – or used in speaker mode.

CallMe™ is a new cost-effective Subscription Codec service that lets contributors send high-quality broadcast audio back to the studio using the internet, without the need for dedicated hardware or software.

It has been developed to let Radio and TV Stations put a contributor on-the-air without having to send out an Outside Broadcast vehicle or for them to have any special hardware, software or even specific technical knowledge.


Our entire V-400 clock range has received an engineering and design refresh to provide enhanced operability, lower power consumption and additional features. The displays themselves are clearer and infra-red remote control for setup is included as standard, as is stopwatch operation.

TimeLord-Net has received a very welcome update, thanks to its new modular design it is the only master clock you will ever need. Keeping its greatest qualities while also being able to take in just about any time reference using the four module slots and built in NTP capabilities.
The new TimeLord-µNet is a small, cost-effective solution to time referencing, a simple small form factor NTP time server that includes its own GPS antenna for an accurate time reference. TimeLord-µNet comes with PoE capabilities and will lock to GPS on power up with very little user interaction needed.

The Industry-standard ACCESS-IP Audio codec just got better with the addition of Opus Codecs and Dual-Streaming capability. It is not for nothing that the ACCESS the industry-standard audio codec and with well over a thousand sets in daily use in the UK alone, the fact is, it really works.
The Comrex ACCESS especially comes into its own on mediocre and contended connections as can happen when using 3G/4G over the public internet where dynamic jitter buffering keeps latency down to the absolute minimum that a connection can support and clever forward error correction and error masking mean that lost packets are not missed. BRUTE Broadcast-Reliable-UDP-Enhancement and Congestion Avoidance further increase the robustness of the connection where packet losses of 25% and above are barely noticed. The Traversal Server gets around NAT router and Firewall issues by monitoring codec addresses and managing connections, further improving its usability on public connections. The ACCESS is also N/ACIP compatible that allows inter-working with other codecs and can also work seamlessly using SIP, making it compatible with IP Phone calls also.

OPUS Codecs which provide low-delay robust high quality audio are now included in the ACCESS family including the BricLink. Having OPUS as standard, allows compatibility with the Vortex CallMe Browser codec that lets guests and reporters connect directly to the Studio without the need to send out equipment or for the guest to visit the studio. Clicking on a web link “goes Live”.

Of major significance, is the addition of Dual Streaming capability which allows the use of two or more different data paths to connect back to base. Until now, this has required the use of an expensive external network-combining device and this important capability is now included within the ACCESS-USB2. Mobile dongles from different networks can be plugged in and clever data-throttling algorithms ensure that data is shared properly between the connection paths including ones with vastly different streaming capabilities. Algorithms in the Rackmount studio codec manage the re-combining of the data to provide even more robust and stable audio than previously.


MCC is the BRIC IP Codec Management Software that helps control, maintain and monitor your ACCESS, BRIC-Link or MIDAS codecs. Call/Drop function for remote use, Packet Loss, Delay, Call Quality and many other parameters to help keep your broadcast seamless and problem free with full control of your codecs from a single instance of Windows. Manage codecs, profiles and monitor delay, call quality and packet loss so that your broadcast runs as smoothly with multiple workstations and codecs.

LiveShot 2nd Generation multi-stream codec from Comrex provides ultra-low latency, full-duplex HD/SD plus Comms over single or multiple IP connections. Using techniques learned with the industry-standard ACCESS, LiveShot uses the same technology to stream video and audio over challenging public Internet connections such as 3G, 4G, WiFi and satellite, at bitrates from 32kb/s to 15Mb/s which it can combine for bonding and diversity without the need for additional hardware.

LiveShot uses state-of-the-art H.264 HIGH Profile video and AAC-ELD audio coding with less than 200ms delay, while its intelligent buffer manager keeps latency to a minimum on any network, making LiveShot the ideal tool for live two-way outside broadcasts. As well as the full-duplex video and audio stream, LiveShot provides an independent two-way cue / IFB channel which is available via Bluetooth or a wired headset in the field.

The Portable unit fits between a broadcast camera and its battery and incorporates two "XLR-style" USB sockets to accommodate flexible gooseneck adapters, each carrying one or two wireless modems. The CrossLock technology built into LiveShot combines the data bandwidth from several network connections (e.g. multiple 3G dongles) for higher-quality streams. No service contract or subscription is required and the separate data streams are automatically recombined by the 1U LiveShot Rack unit back at the studio.

The LiveShot Central Server provided by Comrex will allow remote management of your whole family of LiveShot codecs directly from a web browser. It can even be used to pull down better-than-live quality content which has been archived to the Portable's SD card during a broadcast. When combined with CrossLock, LCS makes firewall traversal a breeze and allows connections to be established from either the field or studio unit at the touch of a button.

The V4X Intelligent 3G/4G Antenna is the ideal partner for any device that needs to stream audio or video using a 3G/4G mobile connection.

Using a patented intelligent multi-beam antenna array, V4X extends the range and throughput of a 3G/4G connection, bringing stable data throughputs around 2Mbps in most 3G locations without difficulty. Compared with the small aerials built into 3G/4G dongles, the V4X provides some 20dB additional gain with excellent stability. Intelligent selection of the cell with the best data throughput ensures optimum connectivity from any location.

Tests using V4X to connect to 3G/4G with an ACCESS IP Audio Codec in places where 3G/4G coverage is marginal and reception poor, have proved the remarkable capabilities of this combination for outside broadcast use; indeed they are in daily use for news, current affairs and sports coverage in places where only ISDN and wired connections would have been considered before.

The V4X acts as a Wireless Access Point and devices are then connected using a WiFi or cabled network connection, allowing the optimum siting of the V4X for 3G/4G reception whilst still providing excellent connectivity.

The new V4X-PRO with IP65 protection rating has been specifically designed for pole-mounting and outdoor use.
