The DL154 delivers legendary MIDAS sound quality in a cost eective, discrete 2U chassis
that utilises time-tested and proven MIDAS technologies. Equipped with 8 channels of
MIDAS premium mic-pre ampliers with 2.5 dB gain steps and 16 balanced line level
outputs, selectable sample rate and dual redundant AES50 network ports the DL154 is the
ideal partner to the PRO 1 and PRO 2 digital consoles – signicantly increasing the network
capacity and number of mic. inputs and analogue outputs.
User interface controls and feedback is via an intuitively laid out front panel. The controls
and LED indicators provide ease of use and instant feedback at a glance. All primary
connections use high quality balanced XLR connectors.
Housed in a road-ready, rugged 19" 2U rack-mountable chassis, the DL154 is ideally suited
for storage in standard ight cases (not included).
Integration WithinThe MIDAS Product Range
Styled to match our existing console aesthetic, MIDAS high performance I/O has never
been easier to use - or more cost eective.

Architect’s & Engineer’s Specication
The MIDAS DL150 series of I/O units are a one piece solution housed in a rugged 19" 2U rack mount chassis with cosmetic trim suitable for use and
storage in a road ight case.
All user interface controls and feedback are located on the front panel. User interface controls are laid out for ease of operation with consideration
for the amount of user feedback required. All switches are high quality momentary type with integral blue LED illumination and printed
switch caps.
All primary connectors are on the rear of the unit. All inputs and outputs are on balanced XLR connectors. All analogue audio inputs and outputs
are tolerant of 48V connection and short circuit protected. The DL150 series only use Neutrik XLR connections.
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 modied version of the one used in the DL251.
The DL150 units use an internal switch-mode power supply.
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.
