keeps dropping out.
Poor connection, defective
cable, or source is unstable.
Check connections and cables. Confi rm you are using
suitable cable of proper impedance. If cables and
connections are OK, source may be unstable.
I am having trouble
daisy-chaining my
digital audio through
multiple speakers.
Cable may not be suitable for
digital application.
Make sure you are using cables per the S/PDIF and
AES/EBU specifi cation, as described on page 44 in
this manual.
My remote control
doesn’t work all of the
time.
Batteries weak.
Remote not pointed at the
Front Left speaker.
(Remote will not work with
LSR4312SP alone.)
Make sure remote is pointed at the Front Left

in the ON position).
My subwoofer will not

lights at all anywhere
on the subwoofer.

LSR4328P
USB connection and/or CAT5
Network cables not properly
connected.
Missing terminator.

the required voltage
Firmware Incompatibility
Check all network connections to make sure the CAT5
cable is inserted all the way into each jack.
Make sure you have two network terminators
installed in your system so that all RJ485 jacks are in
use. Confi rm the USB cable from your computer is
connected to the front left speaker (the speaker with
LEFT DIP switch in the ON position).
Disconnect and reconnect power cord. Frequent
occurrance indicates inadequate supply voltage.
This should be corrected with the application of an
external power conditioning device.
