DL441 analogue input module
The DL441 analogue input module provides eight balanced line (or mic) inputs. Its rear
panel houses eight input XLRs, each having
check and 48V LEDs.
The line inputs may be used as simple unity gain inputs to the XL8, such as insert
returns. However, there is also provision for gain adjustment in 5dB steps from -5dB to
+40dB. This allows very high signal levels to enter the system and means that the
same hardware can be used for mic inputs, if required by the system.
When used for microphones the input can also provide 48-volt phantom power.
