M28 – MARANI 28 Channels Rack Digital mixer
M28 is a 3 rack unit high performance digital mixer. On the front panel, among its 24 input connectors, 16 of them can be used as MIC or LINE. Together with the 16 Mic/Line Inputs, 6 AUX Output channels (two of them can be selected as Monitor Output mirrors) and the Main LEFT and RIGHT channels are available on XLR connectors, the 8 Line Inputs are on ¼ Jack. On ¼ Jack is also available an earphone connector, whose gain is adjustable, available as MONITOR OUTPUT.
The M28 supports USB stereo recording. By connecting a USB Stick to front panel's USB connector, the M16 it's providing stereo or dual-channel recording and playback, allowing to select the recording source in between input and output channels. M28 is managed with powerful MARANI DSP engines, providing a series of sophisticated audio processes like up to 1024 taps FIR filtering on MAIN LEFT and RIGHT Outputs, Effects, Ducker, RTA, Feedback Eliminator, Automixer and more. Moreover, each input and output channel contains Parametric Equalization, RMS Compressor, delay and other useful processes. On Each output is also available a 31 bands Graphic Equalizer.
In addition, there's a WIFI module inside the M28, making it more convenient to connect the device with its dedicated PC interface software or iPad APP, for real time monitor and parameters editing, especially in studio and live performance application. Each device can be connected by up to 4 WiFi connection (PC or iPad) and 10 Ethernet connections(PC), for a total of 14 devices connected at the same time. If a modification to the M28 setting is done with one of the devices, the modification is reported automatically to all the others connected in parallel. Firmware update is also available via simple software operation.
To the embedded 24 channels, 4 more Input Channels can be added via extension cards: the extension cards can be different and allow the extra 4 channels to come from different sources as standard analog ones, AES or Dante™.
