Appendix A: Service Information
Poor sound
• Is it loud and distorted? Make sure that you’re not
overdriving a stage in the signal chain. Verify that
all level controls are set properly.
• Is the input connector plugged completely into
the jack? Be sure all connections are secure.
Noise
• Make sure all connections to SRM-Flex are good
and sound.
• Make sure none of the signal cables are routed near
AC cables, power transformers, or other EMI-inducing
devices.
• Is there a light dimmer or other SCR-based device
on the same AC circuit as SRM-Flex? Use an AC line
filter or plug it into a different AC circuit.
Hum
• Try disconnecting the cable connected to the input
jack. If the noise disappears, it could be a “ground
loop,” rather than a problem with SRM-Flex.
Try some of the following troubleshooting ideas:
• Use balanced connections throughout your
system for the best noise rejection.
• Whenever possible, plug all the audio
equipment’s line cords into outlets which share
a common ground. The distance between
the outlets and the common ground should
be as short as possible.

Troubleshooting
No power
• Our favorite question: Is it plugged in? Make sure
the AC outlet is live [check with a tester or lamp].
• Our next favorite question: Is the power switch on?
If not, try turning it on.
• Make sure the line cord is securely seated in the line
cord socket and plugged all the way into the AC outlet.
• Are the power LEDs on the top and front panels
illuminated? If not, make sure the AC outlet is live.
If so, refer to “No sound” below.
• The internal AC line fuse may be blown. This is not
a user serviceable part. If you suspect the AC line
fuse is blown, please see the "Repair" section next.
No sound
• Is the level knob for the input source turned all
the way down? Verify that all the volume controls
in the system are properly adjusted. Look at the
sig/OL LED and meters to ensure that SRM-Flex
is receiving a signal.
• Is the signal source working? Make sure
the connecting cables are in good repair and securely
connected at both ends. Make sure the master volume
level is turned up sufficiently to drive the inputs
of the speaker.
• Make sure the input source is not muted or has
a processor loop engaged. If you find something
like this, make sure the level is turned down before
disengaging the offending switch.
• Has it shut down? Make sure there is at least six
inches of free space behind each SRM-Flex.
