User Manual
The DL150 series I/O units are mixed technology products combining analogue and digital circuitry. These are combined on the
input and output cards using multi-layer horizontal PCBs. Extreme care has been taken when planning and executing the PCB
layout to maintain good grounding and analogue/digital separation.
The DL150 series units use proven technology from the D251 I/O unit from the current MIDAS range. The analogue input and
output cards are identical, the AES3 digital card is similar to the one used in the PRO2 surface and the CPU card is a modied
version of the one used in the DL251.
The user interface software is based on the same menu system currently used on the DL451 and has provision for all of the
functions these units can perform.
Equipped with 24 channels of MIDAS premium mic-pre ampliers with 2.5dB ultra precise gain steps the DL150 Series are the
ideal partner to the PRO1 and PRO2 digital consoles, signicantly increasing mixable mic inputs.
User interface controls and feedback are accessed via an intuitively laid out front panel. The controls and LED indicators provide
ease of use and instant at a glance feedback. All primary connections use high quality balanced XLR connectors.
Integration Within The MIDAS Product Range
Styled to match existing MIDAS console livery, MIDAS high performance I/O has never been easier or more cost eective.
