PRESS SPLITTERS | Press conferences today

When there is a single audio source but many possible receivers and users, it is necessary to distribute that signal in such a way that the quality of the audio signal is not affected. If we also want to avoid possible noise problems and isolate multiple signals, the solution is to use a Press Splitter.

In this way we avoid the typical image of the football player surrounded by microphones and cables, replacing it with a simplified image with a single microphone.

In a press room, the voices of one or more speakers must be sent to multiple media outlets. Typically, the signal from these microphones is routed to a console or processor for processing and delivered for distribution to the media.

The role of the Splitter starts here:

This signal, preamplified and treated by the console at line level, will be connected to the input of a Press Splitter, which, depending on the outputs it has, will be able to supply that identical and even amplified audio signal (if the Splitter is active) to between 8 and 32 users.

Audio Splitters (if required) work with transformers. Transformers perform signal distribution across multiple outputs identically. Transformers transfer voltage between windings without electrical contact between them. In this way an isolation of the noise between windings is created. So if our Splitter receives a signal contaminated with noise from the environment, the output will be a clean signal isolated from that noise.

The CMRR (common-mode rejection ratio) indicates the ability of a device to reject signals induced in common mode. High-quality transformers offer high CMRRs of up to 118 dB.

Professional audio transformers feature protection via magnetic screens made of a high permeability material, ensuring that the magnetic field flows through the protection and not through the transformer core. In this way, possible magnetic interference from the environment (such as those produced by a TV monitor, power transformers, etc.) will be rejected.

A Passive Splitter works by means of a transformer so that the signal is distributed to each user with the same level (line level) with which it has arrived from the console. It is a device that does not need to be connected to the electrical network to work, making it very useful outdoors, for example. As a passive device, there is a small insertion loss.

An Active Splitter has a transformer and amplification or only amplification. In other words, the main characteristic is that the amplification stage will give you the option of modifying the gain by amplifying or attenuating the signal coming from the console. In addition to this feature, it can be equipped with visual monitoring, for example.

In both options, the audio input is balanced by a transformer that gives it a CMRR of more than 100 dB.

Within our range of Active Press Splitters, you can choose::

• Number of outputs: 8, 12, 16, 24 or 32 outputs
• Format: portable, 19″ rack-mounted box, or for installation in a wall, floor, or table box
• Monitoring: Visual LEDs, available for each output or only for the input.
• Gain: per output or per group of outputs
• Isolation: all our splitters have a transformer at the input, and you can also choose to have one for each output.
• Dante / analogue signal: there is the option of two input signals, selecting the one you want to work with: analogue signal and digital signal from the Dante network.

There are rooms where digital video signal distribution is also necessary. Within our range we have the possibility to choose press splitters with:

• Hybrid Signal, Audio and Video 3G-SDI: analogue audio and digital video signals are distributed to the press in the same equipment.
• 3G-SDI video signal and de-embedded audio: a single 3G-SDI video signal reaches the equipment and it is responsible for distributing the video signal, de-embedding the audio from the digital frame, converting it to analog and distributing it to the press as an analog line-level audio.
