Appendix A: Service Information
No Sound
• Is the GATE THRESHOLD control turned up too high?
Turn the GATE THRESHOLD all the way OFF and see
if you hear anything.
• Is the signal source turned up? Make sure the
signal level from the mixing console (or whatever
device immediately precedes the SQ•2) is high
enough to produce sound through the system.
• Are you using the SQ•2 with an insert plug in an
insert jack? Make sure that you are using an insert
cable, and not a mono Y-cable.
Poor sound
• Is it loud and distorted? Turn down the signal
coming from the mixer or signal source.
• Is the input connector plugged completely into
the jack? Make sure all connections are good and
sound.
• Switch the CHAN IN/OUT switch in and out to
compare the sound with the compressor in the
signal path and out of the signal path. This can
help determine if the problem is with the SQ•2 or
elsewhere in the system.
Noise/Hum
• Check the signal cable between the mixer and
the SQ•2. Make sure all connections are good and
sound.
• Make sure the signal cable is not 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 SQ•2? Use an AC
line fi lter, or plug the SQ•2 into a different AC
circuit.
Warranty Service
Details concerning Warranty Service are spelled
out in the Warranty section on page 19.
If you think your SQ•2 has a problem, please do
everything you can to confi rm it before calling for
service. Doing so might save you from the deprivation
of your compressor and the associated suffering.
These may sound obvious to you, but here are
some things you can check. Read on.
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 red LED above to the POWER switch
illuminated? If not, make sure the AC outlet is live.
If so, refer to “No Sound” below.
• Is the fuse blown? If the POWER LED on the front
panel is not illuminated and you are certain that
the AC outlet is live, if is possible the fuse has blown.
To remove and replace the fuse:
1. Disconnect the line cord from the IEC socket.
2. Remove the fuse drawer by prying it open with a
small screwdriver. It will slide all the way out.
FUSE
3. Remove the fuse and replace it with an
equivalent-type fuse:
315 milliamp slo-blo (T315 A/250 V)
Note: The same fuse is used for both 115 VAC and
230 VAC operation.
4. Replace the fuse drawer by pushing it all the way
back into the IEC socket.
5. Reconnect the line cord and turn the POWER
switch on.
If two fuses blow in a row, then something is wrong.
See the “Repair” section on the next page to fi nd
out what to do.
