Distribute analogue audio anywhere

The AADA416FM quad amplifier allows the flexible distribution of analogue audio in any broadcast environment.

It features four separate audio distribution amplifiers each with an electronically balanced input and four floating outputs, with the inputs and outputs configurable in five different ways to meet your exact requirements.

Configure the inputs and outputs to be what you need

The AADA416FM allows a truly versatile configuration of inputs and outputs.

The most commonly used combinations are configuring the board as a quad amplifier (four mono - or two stereo - inputs and four outputs of each), dual amplifier (two mono - or one stereo - inputs and eight outputs of each) or single amplifier (one mono input and sixteen outputs).

It is also possible to have a mixture of outputs, and configure the board as either a mixed triple amplifier or mixed dual amplifier.

Guarantee robust outputs

The AADA416FM has the essential low noise and distortion which allows the audio to pass through more stages of processing without a loss in quality.

The balanced outputs are fully floating which makes them very robust - should one side be connected to ground, the other will double in amplitude to maintain the difference between the balanced signals, giving a correct single-ended system.

Each output has an individual line driver which gives excellent isolation between them, meaning a damaged signal injected on to one of the outputs will not affect any of the others.

Adjust the gain

The AADA416FM can deal with analogue audio that comes from anywhere, with the ability to be configured for the different maximum operating levels that can occur over different geographical areas.

The fixed gain settings (-6dB, 0dB or +6dB) allow you to scale the incoming audio so that it is the same relationship to your full scale level. The variable gain settings (of +/-6dB) then allow you to correct for gain errors elsewhere.

Monitor your audio

A number of useful monitoring tools ensure you remain aware of exactly what's happening to your audio at all times.

Each channel has an individual audio silence detector with adjustable threshold level and duration - useful for alerting you that your audio signal has failed. There is also an overvoltage detector for each channel with adjustable threshold level. Both these tools can be used with GPIs to trigger alarms.

Two 3.5mm jacks are provided for local monitoring using headphones and can be used during installation or when investigating problems, allowing you to listen to the audio at various stages to check for continuity or quality.

Easy to set up and use

It takes no time at all to get the AADA416FM configured and on air. The AADA416FM is manually operated by on-board pots and jumper links, with its economical distribution making it ideal for for cost-sensitive applications.

Save rack space

The AADA416FM will save you rack space, with this 100mm x 266mm module providing up to 48 DAs in a single 2U frame, making it excellent value per channel.

The AADA416FM conveniently fits in Crystal Vision's standard frames (available in four sizes to suit all applications) alongside any other video or audio products from the range.

The audio inputs and outputs are accessed by using either the RM17 frame rear module or the 'easywire' RM37 which features a 64-way DIN 41612 connector, providing plenty of room to solder the wires on to the individual pins.
