Doing a remote? Put Comrex on the line.

When you purchase Matrix Portable, you can be confident that you are using the most rugged and reliable remote broadcast equipment available.

With the TelCell Module, the Matrix can be used as a portable coupler on plain phone lines and with most cell phones. You can connect with anyone, even if they do not have a codec. While the Matrix does not enhance the audio characteristics of the line, the addition of professional microphones and headphones will help maximize your audio quality.

Choose the Matrix Portable ISDN Module when ISDN is available, rather than purchasing an additional codec. It offers MPEG Audio Layer III, G.722 and Comrexs Turbo G.722, allowing you to select the most appropriate combination of fidelity, compatibility and low delay for your needs.

The optional Matrix GSM Module uses GSM CSD (circuit switched data) to deliver 7 kHz frequency response over wireless service . It operates  where GSM circuit switched data is available .  Many carriers around the world offer CSD. In the US, T-Mobile and Cingular were offering this service, however recently they have been discontinuing the Circuit Switched Data service without warning. It has become increasingly difficult to reliably obtain CSD service or to be able to rely on this service for broadcasts and Comrex can no longer recommend this service in the US.

Program and cueback can be sent over the same phone line. This is a real advantage when off-air monitoring is delayed from real-time, such as with HD Radio or when using a profanity delay.

Compact and modular, Matrix Portable is designed to withstand the rigors of the road. Its delivered equipped to handle full duplex audio, with up to 15 kHz audio bandwidth, over standard dialup POTS. Audio quality scales automatically to compensate for poor phone lines, keeping you connected and on the air.

Matrix Portable provides the most convenient way to deliver superior audio quality on any dialup telephone circuit. Combining the most practical user features with Comrexs technology advancements, it is unquestionably the first choice for those who seek flexible audio remotes.
