I/O อินเตอร์เฟส Stage Box Midas DL252 16 Input, 48 Output Stage Box with 16 MIDAS Microphone Preamplifiers, Three AES50 Network Ports, Ethernet Control Port
The DL252 from MIDAS is a 5U 19″ rackmount fixed-configuration I/O unit with sixteen microphone/line inputs and forty-eight line outputs. Limited to analog connections, the unit provides a more cost-effective solution for those not needing the flexibility of MIDAS modular I/O hardware.
MIDI (In, Out, Thru) connectors and an Ethernet control port are fitted as standard. Three AES50 ports handle the (n+1) redundant digital audio interface. The DL252 is capable of being switched between 96 kHz and 48 kHz via the front panel.
A rear panel “Mute All Outputs” button is provided for aiding in onstage re-patching. The unit is also equipped with dual-redundant, universal power supplies.
