MADI.MONI is an extremely compact MADI monitor/analyser, allowing engineers to rapidly check the “go/no-go” status of MADI signals of any type (including S/MUX), and to monitor any audio channel or pair of channels on headphones. It is an essential tool for broadcast facilities, OB vehicles, theatres, live sound engineers and product development labs.
MADI.MONI accepts MADI signals in either coaxial form via a BNC socket, or optically via a suitable SFP cartridge. An empty SFP carrier is provided, into which may be fitted any compatible optical receiver or transceiver, to suit the fibre standards in use. Suitable manufacturer-approved DDM (Digital Diagnostics Monitoring)-capable cartridges – enabling analysis of the optical signal – may be specified at the time of order. All MADI formats are supported – 56 or 64 channels and 48 or 96 kHz frame rates – with auto-detection. Sample rates supported are 32, 44.1, 46, 88.2, 96, 176.4 and 192 kHz.
Operation of the analyser is essentially automatic: LEDs on the unit confirm the format of the MADI signal in terms of channel count (56 or 64 channels), frame rate (48 or 96 kHz) and base sample rate (44.1 or 48 kHz). Two sets of “traffic-lights” (red, yellow and green LEDs) indicate the amplitude and jitter of the incoming signal as “no-go”, “marginal” or “go” respectively. Two further LEDs confirm the input port in use.
Control of MADI.MONI is very simple, using four push buttons: one toggles between volume setting and channel selection modes, two SET buttons scroll up and down through volume levels or channel numbers; the MENU buttons allows access to various device settings, including input and output selection, mono/stereo operation and scaling factor.
