TROUBLESHOOTING & SYSTEM CHECK LIST
X12, X24 and X14 Controllers
Are the sense lines properly connected to the amplifiers? Are the correct Loudspeaker Specific Processing
modules installed?
D26 Digital Controller
Is the proper loudspeaker-specific configuration selected on your D26?
External Amplifiers
Are all power amplifiers used with X-type externally powered line array modules and subwoofers properly
configured? In particular, check voltage gain settings and input gain settings.
Signal path – for self-powered systems
Are all line array modules properly connected? Are the subwoofers connected with the same polarity as the
main arrays? If the subs and the main arrays are driven by separate sends from the main console, are those
outputs in phase?
Loudspeaker wiring
Are all line array modules receiving the same signal? For externally powered modules, are all three sections
functioning? Are they in proper polarity? Do the subs have the same polarity as the main array? Are all the subs
wired with the same polarity (if you turn one section off does the level decrease (proper polarity), increase
(trouble!) or stay the same (also trouble!)?
