Sonance LR2 - Manual (Page 2)

CONNECTING THE LS2 AND LR2
(see Illustration 3 )
IMPORTANT: Make sure all source components and power amplifiers are
turned OFF before making any connections.
Do not plug the power supply into a wall outlet until all connections have
been made.
1. Use a stereo RCA cord to connect the audio source component to the LS2’s
Unbalanced Input.
2. Use shielded 4-conductor wire, such as Sonance MediLinQ 22/4 audio wire
(part #91874), to connect the LS2’s Balanced Output terminals to the LR2’s
Balanced Input terminals as shown in Illustration 3. The maximum length
of 4-conductor wire that can be used is 1,000 feet.
• Make sure to connect the “+” terminals together and the “–” terminals
together and to connect Left to Left and Right to Right.
IMPORTANT: To minimize ground noise, connect the wire shield ONLY
to the ‘SH’ terminal on the LS2 sender. DO NOT connect the wire shield
to the LR2 receiver. Make sure not to allow the shield to touch any of the
adjacent wires.
• If you’re sending the LS2’s signal to multiple LR2s, ‘daisy-chain’ the LR2s
together using lengths of 4-conductor shielded audio cable. You can feed
up to nine (9) LR2 receivers from a single LS2 sender. The maximum
length of 4-conductor wire that can be used is 1,000 feet total.
• Do not connect the wire shield to any of the LR2 receivers.
4. Connect the included PS-1 power supplies to the LS2’s and LR2’s 12V DC
jacks and plug them into non-switched AC outlets that supply continuous
current.
• You can power up to nine (9) LR2 receiver units from the LS2’s single
power supply. Connect a power supply cable with standard 2.1mm
internal diameter connectors between the LS2’s 12V DC Out jack and the
first LR2’s 12V DC In jack, and then daisy-chain the next LR2’s 12V DC In
jack to the first LR2’s 12V DC Out jack using another power supply cable
(up to 9 total LR2s). Repeat for all LR2s.
