Test State
The 'Test' state is only accessible by pressing the 'Test' button on the remote control. When in this state, a
pink noise 'test tone' will be played from each speaker instead of the selected source input. This tone will
come from one speaker at a time, in 2.5 second intervals, in the following order: left front, center, right front,
right rear, left rear, sub. To exit this state, just press the 'Test' button again.
Use the Test state to verify that your speakers are connected properly, or to set levels between the rear, front,
and center channels.
Frequently Asked Questions
Q. Can I extend the speaker cables?
A. Yes. Purchase standard speaker wire, 20AWG and cut and strip to desired length. Using any other
gauge wire is not recommended, may damage the system and may void your warranty.
Q. There is no sound coming from one (or more) speakers.
A. Confi rm that the speaker is connected properly. When inserting the wire, make sure the bare wire
sits on the metal connector in the spring clip. This is critical – metal must be on metal – or the
connection will not be suffi cient. Sometimes the plastic wire shielding is pushed onto the metal
connector, which prevents the wire from making a solid contact with the connector in the spring clip.
This will also prevent your speaker from working. If this is the case, simply pull the wire out some so
that the wire makes a clean contact with the metal part of the connector.
Q. What happens if the speaker wires are reversed? (red wire to black spring clip on one speaker, red wire
to red spring clip on the subwoofer, or vise versa)
