SERVICE INFORMATION
Bad sound!
• Is it loud and distorted? Follow the procedures de-
scribed in the “Quick Start” section to verify that the
levels are set properly.
• Is the input connector plugged completely into the
jack? Be sure all connections are secure. It’s a good
idea to periodically clean all electrical connections with
a non-lubricating electrical contact cleaner.
Noise
• Make sure all connections to the active speakers are
good.
• 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 the SRM150? Use an AC line
filter or plug the SRM150 into a different AC circuit.
Hum
• Turn the MAIN LEVEL control all the way down. If the
noise disappears, it’s coming from the signal source. If
not, try disconnecting the cables connected to the input
jacks one at a time. If the noise disappears, it could be a
“ground loop,” rather than a problem with the SRM150.
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.
Never remove the ground pin on the
power cord of the SRM150 or any other
component. This is very dangerous.
If you think your Mackie product has a problem,
please check out the following troubleshooting tips and
do your best to confirm the problem. Visit the Support
section of our website (www.mackie.com/support)
where you will find lots of useful information such as
FAQs and other documentation. You may find the answer
to the problem without having to send your Mackie
product away.
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.
• Is the blue light on the front panel illuminated? If not,
make sure the AC outlet is live. If so, refer to “No sound”
below.
• The resettable circuit breaker has popped. Refer to
“FUSE” [9] on page 10 for information on the circuit
breaker.
No sound!
• Is the input gain control [3] or the MAIN LEVEL [6]
control turned all the way down? Follow the procedures
in the “Quick Start” section on page 4 to verify that all
the volume controls in the system are properly adjusted.
• Is the signal source working (and making union scale)?
Make sure the connecting cables are in good repair and
securely connected at both ends. Make sure the output
volume (gain) control on whatever is connected to the
SRM150 is turned up sufficiently to drive the inputs of
the speaker.
