TROUBLESHOOTING
With proper care and handling, your mixer should give you years of trouble-free
service. However, if your SSM-1250 is not working properly, follow these sugges-
tions to see if you can eliminate the problem. If you cannot, take the mixer to your
local RadioShack store for assistance.
Problem Possible Solution
Nothing works Check the AC power connection and make sure the AC
outlet is “live.”
Check all the connections to the system (amplifier/
receiver, input sources, and so on).
Check the fuse. See “Replacing the Fuse” on Page 21.
No signal from an audio
input source Make sure the OFF/ON/TALKOVER switch is not set to
TALKOVER .
Check the mixer’s and the source’s control settings.
Check the connection between the mixer and the input
source.
Hum from PHONO
sources
Make sure the turntable’s ground wire (usually black or
green) is connected to the
GND screw on the back of
the mixer.
Hum from other input
sources Make sure there are no low-level inputs connected to
the
LINE input jacks.
Feedback “squeals” Move the microphone further away from the output
speakers or use a unidirectional microphone.
