SYSTEM OPERATION
Electronic Controller
The PS8 TDcontroller is precisely matched to the PS8 & LS400 cabinets and includes sophisticated protection systems. Using
PS8 & LS400 without a properly connected PS8TD will result in poor sound quality and can damage the components. PS8 &
LS400 can also be used with the NX241 Digital TDcontroller.
Dispersion configuration
After quick-release of the front grille from its fixings, the HF Horn can be rotated in 4 positions for dispersion configuration.
Subbass
The PS8 can be used without optional LS400 Subbass. Active two-way operation with the LS400 is included in the PS8TD.
One LS400 matches 2 x PS8, additional LS400 may be used for enhanced effect.
Speaker Cables
PS8 are wired 2- & 2+ on Speakon connectors, LS400 on 1- & 1+. Loop through Speakons are present on both. Single
identical cables can thus be used to loop through combinations of up to 2 x PS8 & 1 x LS400 in no particular order.
