12 GEO S12 – RS15 / CD18/S2/GEOSUB SYSTEM CHECK LIST
It is essential to execute all these check steps prior to perform a sound check on the “front end” to the
system. Following this checklist step by step will prevent many troubles and will save time in the end.
12.1 Are the NX242 Digital TDcontrollers properly configured?
IMPORTANT
If you must change any of the parameters listed above, make sure that you use the same
values on all NX242’s.

All channels 26 dB refer to amp 0 dB 0 ms 0 dB 0 5 bars
(1) Local gain and delay values are inter-locked channel 1&2
(2) values for recommended amplifier gain and power : should be set in agreement with selected
amplifiers specifications
(3) Should be in agreement with implemented cluster; acts on a shelving filter designed to compensate
for LF coupling.
(4) Disabled when using digital inputs.
12.2 Are the amplifiers properly configured?

12.3 Are the amps and the NX properly connected?
Check that the sense lines on the NX242’s are properly connected by applying a signal to the
corresponding output and verify that the correct Sense LED illuminates.
