New from Sonifex are three transformer-based passive splitter units.
The CM-AESB3 is a passive ‘one-to-three’ splitter designed to split a single AES3ID digital audio source to up to three destinations, using female BNC connectors. Aimed at the video production and broadcast environment, the CM-AESB3 splits the input signal through high quality transformers. Termination into 75Ω can be applied, to unconnected outputs to maintain optimum carrier parameters.
The CM-AESX3 is also a passive ‘one-to-three’ splitter ,used to create multiple AES3 digital audio signals from a single source, using Neutrik XLR connectors. It provides solutions to a range of digital signal distribution problems, where correct termination is essential to maintain signal integrity and 110Ω termination can be applied to unconnected outputs.
The CM-MS3 can split a single microphone or line source to up to three destinations, using Neutrik XLR connectors. It uses high-quality audio transformers that are capable of accepting input levels up to +18dBu, making the splitter useful in both microphone and line level splitting applications.
The CM-MS3 offers three methods of providing phantom power to a microphone connected to its input: from the external +48V DC power connector; from a microphone amplifier connected to Output 1 (direct); from a microphone amplifier connected to Output 2 (phantom loopback). Controlling which method is used to provide phantom power is achieved with simple push switches. It is possible to concurrently power a microphone using any two of the above methods without degrading audio performance, thus providing power supply redundancy. Also, ground loop hum problems can be quickly eliminated using the push switches to lift Pin 1 of the output connectors (Output 2 & 3 only).
‘Our new small-form, single three-way splitters are robust, high-quality units, housed in aluminium and they require no power to operate,’ says Sonifex Sales Manager, Eamonn Heffernan. ‘They use very high-quality audio transformers to give top quality performance and galvanic isolation.’
