Midas DL252 16 x 48 Fixed Format I/O Unit
ดิจิตอลสเตจบ๊อกซ์ Midas DL252 I/O Stage Box 16 Input, 48 Output with 16 MIDAS Microphone Preamplifiers, Selectable 96 kHz or 48 kHz sample rate operation, 3-AES50 Network Ports, Ethernet Control Port, MIDI In, Out and Thru connectors
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.
- 16 award-winning MIDAS microphone preamplifiers with switchable +48 V phantom power
- 48 actively balanced low impedance line level outputs
- Selectable 96 kHz or 48 kHz sample rate operation
- Remote operation up to 100 m via CAT5/5e cable
- All settings programmable from front panel controls or console
- PSU status indicator LEDs and configuration switches on front panel
- 3 AES50 network ports for redundant connections
- MIDI In, Out and Thru connectors
- Features Neutrik etherCON* AES50 network ports
- Rugged 5U rackmount chassis for durability in portable applications
- Dual redundant auto-ranging universal switch-mode power supplies
- 3-Year Warranty Program*
- Designed and engineered in the U.K.
