RB-DMX4 4 x 4 Channel Digital Audio Mixer/Router
Sonifex will introduce two new products in its Redbox professional audio family at IBC 2009 in Amsterdam.

The RB-DMX4 digital mixer can mix or route 4 mono input channels into 4 mono outputs, or 2 stereo inputs into 2 stereo outputs. The inputs are sample rate converted to allow sources of different sample rates to be mixed with the output sample rate being defined independently. Each pair of inputs is selectable via front panel push buttons, from either AES/EBU balanced XLRs, S/PDIF unbalanced phonos or TOSlink unbalanced optical inputs. There are 2 stereo outputs available as simultaneous AES/EBU balanced XLRs, S/PDIF unbalanced phonos or TOSlink unbalanced optical outputs. The output sample rates are selectable from between 32kHz and 192kHz.

There is a monitor socket on the front panel with a gain pot to allow users to monitor the output of each channel. Each input has a trim pot, which can be used to attenuate the input signal which allows for a perfect mix of channels at different audio levels. Audio presence LEDS around each input button give an indication of input audio level. There are also 4 presence LEDS which give an indication of output level.

RB-DD4 4 Channel Digital Audio Delay The RB-DD4 4 channel digital audio delay allows users to delay 4 mono channels of audio independently or together. Each channel delay is user selectable from multiples of common video frame rates, or a user defined value set via the serial interface. The unit is perfect for synchronizing audio to video which has been delayed by processing latency.

Using front panel controls you can select the length of one frame of delay, the multiple of frames to delay by and which channel needs to be delayed, with an option for 'ALL' channels.

The RB-DD4 offers with three different types of connection for each input and output including AES/EBU, S/PDIF and TOSLink. All three different types of output can be used simultaneously. There is a monitor socket on the front panel which allows users to listen to each mono channel, by front panel selection. The channels can be optionally monitored as pairs using a rear panel stereo option. Audio presence is detected and displayed for each channel on front panel LEDs.

By using the Sonifex SCi serial software on the RB-DD4, the unit can be programmed for different delay durations, levels and switching functions so that the unit can be programmed for specific applications.
