Specifications
Audio System Engine
Midas DL371
The PRO Series processing engine is a 7U 19” rack mount unit, which houses up to 7 audio
processing modules and routing hardware. Employing advanced FPGA architecture, it has
three removable power supplies, only two of which are required for full operation. The
power supplies are auto-voltage sensing, auto-switchover, hot-swappable, are tted with
locking AC connectors and are identical to, and therefore interchangeable with the PSU’s
in the PRO Series Control Centre.
The engine has dual-redundant HyperMac ports (both CAT-5e and Optical on the PRO6
and PRO9) which provides the digital equivalent of a 384-way (192 in + 192 out) multi-core
between the stage and FOH. There are also eight AES50 ports, which facilitate connections
to the PRO Series DL351 stage box, and/or other AES50 I/O hardware. It is also possible to
use any PRO Series with DL251, DL351, DL451 and DL431 plus the Klark Teknik DN9696 Hi
Resolution Audio Recorder and DN9650 Network Bridge.
The processing engine is loaded with 4 modules for a PRO3, 5 for a PRO6 and 6 for a
PRO9 in the standard conguration, with an extra-cost option for an n+1 redundant spare
module.

Midas DL351
The DL351 is a 7U 19” rack unit, can provide a maximum of 64 audio inputs and 64 audio
outputs. It has the same user-congurable card format as the DL451 but has the capacity
to house up to 8 cards, which can be any combination of 8 analogue mic/line in, 8
analogue out (XLR), 8 analogue TRS line level in and out, 8 digital in and out (4 AES/EBU
pairs) or a 25 pin D sub card with 8 analogue mic/line inputs and 8 outputs.
Midi in, out and thru, and GPIO connections are supplied as standard. Digital audio
interface is via 4 AES50 ports, one of which can be congured as a spare redundant
connection. Dual redundant power supplies with locking IEC connectors are tted as
standard.
The DL351 can be used with the Midas XL8 and PRO Series of digital mixing systems, or as
a stand-alone AES50 audio interface in a Midas snake and audio distribution system with
remote control via Ethernet.
