9 RS15 SYSTEM CHECK LIST
It is essential to execute all these check steps prior to 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.
9.1 Are the NX Digital TDcontrollers properly configured?
IMPORTANT
If you must change any of the parameters listed below, make sure that you use the same
values on all NX’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 on channel 1&2 and 3&4 in Directional Mode
(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.
9.2 Are the amplifiers properly configured?

9.3 Are the amps and the NX properly connected?
Check that the sense lines on the NX’s are properly connected by applying a signal to the
corresponding output and verify that the correct Sense LED illuminates.
9.4 Are the speakers properly connected?
• Attach the first serie of modules to the bumper
• Before flying, verify that all drivers of all modules are functioning properly.
• Make sure that each RS15 driver is producing proper summation in omni mode:
- The two RS15 individual 15” driver should sum up by 6 dB;
- Doubling RS15 quantity (2, 4 and so on) should also produce 6 dB gain.
• Make sure that each RS15 is producing the proper front/rear summation in directional mode:
