The DL252 is a 5U fixed-configuration I/O unit with 16 mic/line inputs and 48 mic/line outputs. The DL252 is limited to analogue connections and provides a more cost-effective solution for those not requiring the flexibility of MIDAS modular I/O hardware.
MIDI in, out and thru and one 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 a front panel switch.
A rear panel Mute button is available for on-stage re-patching. The unit is also equipped with dual-redundant PSUs.
