These controllers are not interchangeable. Each one is precisely matched to the corresponding cabinets.
Excepted NX241 that covers the entire NEXO range.
NOTE: Earlier PS15TDs (up to serial number 1518) were designed for PS15s without the Impedance
Compensation Network (ICN) (serial number < 23853) and the LS1000 Sub. Using these on newer
cabinets will result in a degradation of sound quality. See page 15 for more information.
PS15Bass use
The PS15Bass is a passive cabinet that uses the same signal as the PS15. It
should therefore be connected in parallel with the PS15. You can use the
same controller for both cabinets; both will be equally protected. If you are
using the active mode of the PS15 the PS15Bass should be plugged into the
LF channel of the PS15 (1+/1-); a short adapter will be required (wired from
1+/1- of the PS15 to 2+/2- of the PS15Bass).
Speaker Wiring
The loudspeakers are connected with Speakon NL4FC plugs (not supplied). A wiring diagram is printed
on the connection panel located on the back of each cabinet.
The 4 pins of the 2 Speakon sockets identified in / out are connected in parallel within the enclosure.
Either connector can be used when connecting amplifiers and also to link to an additional PS cabinet and
optional LSub (if present). This way, a single 4-conductor cable can connect the amplifier rack to 1 or 2 PS
plus 1 LSub.
