Description
The DiGiCo MOD-DMI-MICPRE is a professional microphone preamp interface card designed to expand the input capacity of compatible DiGiCo systems. It provides eight microphone preamp inputs through a single 25-way D connector. Each input features individual low-noise gain control and phantom power for flexible microphone operation. The card integrates directly with the console's normal channel-strip interface for convenient control. This provides a straightforward way to add microphone inputs without requiring an external preamp interface. The DMI-MIC is well suited to live sound, installation, broadcast, and professional audio applications.
Individual Gain Control
Each of the eight microphone inputs provides independent low-noise gain adjustment from -20 dB to +60 dB. This wide gain range allows the card to accommodate different microphone sensitivities and input signal levels. Gain can be controlled directly through the compatible DiGiCo console channel strip. This provides engineers with familiar control over connected microphone sources from the main console interface. The low-noise preamp design helps maintain signal quality throughout the available gain range. This makes the DMI-MIC suitable for both quiet microphone sources and higher-level signals.
Phantom Power and Input Control
The DMI-MIC provides individual phantom power capability for its eight microphone inputs. This allows compatible condenser microphones and other phantom-powered devices to be connected directly to the card. Each input can be managed independently according to the requirements of the connected source. The controls are integrated into the normal console channel-strip interface for efficient operation. Engineers can therefore manage input gain and microphone power without needing to access the physical card. This provides a clean and convenient workflow for professional live audio systems.
High-Quality Audio Performance
The DMI-MIC is designed to provide professional audio performance with low noise and wide dynamic range. Its A-D conversion provides a specified dynamic range of 116 dB, while typical analog noise is rated at -90 dBu. The card provides an EIN specification of 126 dB and CMRR of 74 dB at 1 kHz. These characteristics help maintain clean and detailed microphone signals throughout the signal path. The card also provides wide frequency response at both 48 kHz and 96 kHz operation. This makes it suitable for demanding professional recording and live sound environments.
Flexible Digital Integration
The DMI-MIC can be installed in compatible DiGiCo systems equipped with DMI ports. It is designed for use with S-Series and SD-Range consoles as well as compatible 4REA4 systems. The card provides a direct interface between connected microphones and the digital audio processing environment. Its integration with the console channel strip simplifies configuration and day-to-day operation. The modular DMI format provides a practical way to expand microphone input capacity within supported systems. This makes it useful for productions and installations requiring additional microphone preamp channels.
Professional Connectivity
The DMI-MIC uses a single 25-way D connector to provide access to all eight microphone preamp channels. This compact connection format simplifies cabling within compatible DiGiCo system configurations. The card supports a maximum input level of +22 dBu, providing useful headroom for professional audio signals. Its combination of individual gain control, phantom power, and low-noise performance makes it a versatile microphone input solution. The DMI-MIC is designed for reliable integration into professional audio workflows. It provides an efficient eight-channel microphone preamp expansion option for compatible DiGiCo equipment.
