JBL LSR4312SP Owner's Manual page 14

Quick Start
d. Connect the LEFT, RIGHT, CENTER, L SURROUND, and R SURROUND "through" outputs of
the subwoofer to the inputs of the corresponding speakers. (See the illustration on page 33 in this
manual for reference.)
To connect stereo digital signal sources:
a. Connect the digital output of the source to either the S/PDIF or AES/EBU digital input of
the LSR4312SP.
b. Set the following DIP switches on the rear panel of the LSR4312SP:
i. Select which channel(s) of the digital stream the LSR4312SP will reproduce by enabling DIP
switches #3 and/or #4 for Channel A, Channel B or both.**
ii. To apply bass management to a stereo digital signal, set the LFE / Bass Management DIP
switch (switch #5) to Bass Management.
c. Connect the LSR4312SP S/PDIF and/or AES/EBU output to the S/PDIF and/or AES/EBU digital
input of the LEFT channel speaker.
d. Connect the S/PDIF and/or AES/EBU output of the left channel speaker to the S/PDIF and/or
AES/EBU digital input of the right channel speaker.
* A stereo digital signal can be distributed to speakersin any order using the speaker's inputs and
outputs. Such as: L, Sub, R; R, Sub, L; Right Left Sub; Left Right Sub; Sub, L, R; Sub, R, L.
To connect multichannel (surround sound) digital signal sources:
The S/PDIF and AES/EBU inputs may be assigned to receive an LFE (Low Frequency Effects) signal. Bass
management of multiple digital signals requires an external bass management processor that provides a
monaural or stereo bass managed signal to the subwoofer(s).
a. Connect the digital LFE output of the multichannel source or output of an external bass
management processor to either the S/PDIF or AES/EBU digital input of the subwoofer.
b. Set the following DIP switches on the rear panel of the subwoofer:
i. Typically, the digital signal will carry the LFE signal paired with another signal, most often
the Center channel signal, on the same wire. Consult your documentation to determine
which channel of the digital stream (A or B) carries the LFE signal and set the LSR4312SP to
reproduce that channel by enabling either DIP switch #3 for Channel A or DIP switch #4 for
Channel B. Do not enable both DIP switches.
ii. Set the LFE / Bass Management DIP switch (switch #5) to LFE.
c. Connect the digital S/PDIF and or AES/EBU output(s) to the other speaker that requires the
signal (for example, the Center speaker). (Consult the owners manual for the LSR4328P and
LSR4326P for DIP switch settings and speaker ID information.)
d. If the subwoofer is receiving a bass managed signal from an external processor, make sure the
LFE Low Pass Filter is set to NONE. (See #8 on page 14 for more information.)
** Typically Ch A= Left channel of the digital signal, Ch B= Right channel of the digital signal.
