U-Net connections are also made using Cat5 cables. If longer cable runs are required to U-Net enabled powered loudspeakers, a
robust Cat 5 cable should be used such as Neutrik Etherflex or Belden 1304A. Connectors should be Neutrik Ethercon RJ45
connectors. This will ensure reliable network connections of up to 120 metres. U-Net protocol uses a redundant ring fault
tolerance so connections “daisy-chain" between all units in the network going from port 1 on the first unit to port 2 on the next
and so on before finally making a return connection back to port 2 on the first unit to complete the loop. The U-Net network will
operate perfectly well without a closed loop but it is strongly recommended to use this option so that the network will continue
to work in the event of a break in cable or disconnected connector.
Audio Inputs
Analogue inputs should be connected with a good quality 3-pin Male XLR wired to similarly good quality twin screened cable.
Wiring is the industry standard for balanced connections;-
Pin 1
Ground or shield
Pin 2
+, Hot, in phase
Pin 3
-, Cold, out of phase.
Unbalanced connection can be made if necessary by either wiring ground to pin 3 and signal to pin 2 or ground to pin 1 and 3
and signal to pin 2
AES/EBU input connections are identical to analogue but cable used must be a dedicated 110Ω, low capacitance digital cable
such as Belden 1800F or 1696A
Audio Outputs
Analogue outputs should be connected with a good quality 3-pin Female XLR wired to similarly good quality twin screened cable,
this is particularly important if the Merlin is driving a long length of cable; from front of house to stage for example. Good quality
cable will minimise losses over the cable run. Wiring is the industry standard for balanced connections;-
Pin 1. Ground or shield
Pin 2
+, Hot, In phase
Pin 3
-, Cold, out of phase.
Unbalanced connection can be made if necessary by omitting connection to pin 3. Do not short the unused pin 3 to ground.
AES/EBU output connections are identical to analogue but cable used must be a dedicated 110Ω, low capacitance digital cable
such as Belden 1800F or 1696A.
USB
The front panel mounted USB connection is for direct connection to a PC for Firmware upgrades and other diagnostics.
Connection is standard USB 2.0 and a standard USB type 1 to USB type 2 cable is required
Processing Functions
The Merlin has a freely assignable 4 x 10 routing matrix allowing any input to be routed to any or all of the 10 outputs.
The diagram below shows the processing path on each of the 4 inputs.
