━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

(1) 기능

본 기기는 Dante 네트워크, 아날로그로 연결하여 오디오 신호를 주고받을 수 있어야 하고 PoE 및 48V 팬텀 전원 공급, 소프트웨어를 통한 입출력, 팬텀 전원 등 제어 가능한 기기여야 한다.

System details

Front panel

- Gain and phantom power status LEDs	: Shows the gain/pad setting and

phantom power status for each of

the four input channels.

- Power/ID LED	: Indicates power when the unit

Is on, and blinks in response to a

software command for unit

identification

Rear panel

- Mic/line inputs 1 ~ 4	: Balanced and RF filtered inputs.

Software selectable gain presets:

without pad: 0dB, +15dB, +30dB,

+45dB with pad: -12dB, +3dB,

+18dB, and +33dB +48V phantom

power on each channel

- RJ-45 ethernet connectors	: The left RJ-45 connects to an

Ethernet switch(PoE or non-PoE)

and also provides the DC input for

daisy chained units. the right

RJ-45 provides DC out to daisy

chained units.

- +24V DC input	: Allows the unD4I-L to be powered,

if a PoE ethernet switch

is not used.

- Power link in/out	: Allows DC power to be daisy

chained between multiple units.

- Logic inputs 1 ~ 4	: Allows external contact closures to

be sensed and UDP, messages to

be triggered to external devices.

- Logic outputs 1 ~ 4	: Allows LEDs and other low current

devices to be driven, based on UDP

messages from external devices.

General

- Mic/line input type	: Balanced and RF filtered
