Sonifex Promotes Profanity Delay At NAB 2011
5th April 2011
On the Sonifex booth C2739 at NAB 2011 is highlighted the RB-PD2 broadcast profanity delay. Released last year, this delay has bloomed into a fully fledged feature rich product in daily use all over the world.
Managing Director Marcus Brooke commented: “The profanity delay is one of a number of delay products in our Redbox range. Designed specifically for radio broadcasters it has automatic and simple operation to make it easy to use in a busy broadcast environment. We’ve sold units into the UK, Europe, the Middle East, China, Australia, New Zealand, South Africa and a few into the USA. We’re highlighting the product at the NAB show to show US customers what a good product it is and we’ve got a special show discount of 25% off for all of our delay and embedder/de-embedder products during April and May for US customers”.
The RB-PD2 stereo profanity delay is a 1U 19” rack-mount which features an automatic audio stretch algorithm that allows between 2 and 55 seconds of delay to be built up live whilst “on air”, and maintaining the correct pitch. The delay can also be created by playing an audio file on a Compact Flash™ memory card. When the programme is complete, the audio stretch algorithm seamlessly reduces the delay to zero.
It has both balanced analogue and AES/EBU digital audio inputs and outputs on 3 pin XLR connectors and provides sample rates up to 48kHz at 24 bit. It can act as a combined A/D and D/A unit meaning that analogue inputs can be output as AES/EBU or vice-versa.
The delay can be initiated by pressing the BUILD DELAY button on the front panel. A front panel display shows the amount of delay being built-up, up to the amount initially selected. There are several ways to make sure that any unwanted material is removed from the audio at the outputs. A COUGH function, activated from a dedicated front panel button, allows locally generated sounds being presented at the inputs, such as the presenter coughing or equipment switching noises, to be discarded.
The DUMP function, which is also activated from a front panel button, has 2 different modes. The first DUMP mode removes a section of the most recent audio that has already been buffered, by a pre-selected amount. The second DUMP mode dumps the audio built up in the delay and plays a pre-selected audio file on the Compact Flash™ memory card whilst building the delay again. When the file has finished playing, the delay is then again equal to the duration of the file. The DUMP button can beused multiple times to use up the built-up delay and once used, the unit automatically starts to rebuild the original delay time.
As a last resort, all the buffered audio can be discarded by pressing and holding the DUMP button which activates the DROP function. At the end of a radio show when you want to broadcast live, the delay can be ramped down by pressing the front panel EXIT DELAY button.
A dedicated record mode allows audio presented at either the analogue or digital inputs to be recorded to a linear WAV file on a Compact Flash™ memory card. Additionally, the card format used is PC readable, allowing pre-recorded linear WAV files to be transferred easily from a PC or other such device.
The RB-PD2 features a remote port supplying 8 inputs and 6 outputs, all of which are freely assignable. The inputs can be used to trigger any of the unit’s functions such as build delay, activate cough or enter record mode and start a new recording. The outputs can provide external signalling to indicate when certain events have occurred such as the delay reaching the required value or the outputs are muted. The remote outputs can optionally be made to follow the inputs with the current programme delay inserted between actuation on the input and actuation on the output. This can be useful for timed events that need to account for the delay built up by the RB-PD2.
Because playback from a Compact Flash™ card can be triggered remotely, the RB-PD2 can also be used at a transmitter site to play an emergency audio file via GPI in the event of silence detection.
