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 NXAMP4x1 and NXAMP4x4 Powered
TDControllers.
Dispersion configuration After dismounting 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 LF capability.
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.

[a] Response curves & data : Anechoïc Far Field for the PS8 + PS8TD. Half-Space Anechoïc radiation for the LS400 + PS8TD.
[b] Sensitivity & Peak SPL data : these will depend on spectral distribution and crest factor of program material. Measured with band limited Pink Noise. Nominal
refers to Voice Decade (300 Hz - 3 kHz), Wideband to the specified ±3dB range. Data are for speaker + processor + recommended amplifier combinations. Peak
SPL is at clipping of recommended amplifier.
[c] Directivity curves & data : obtained by computer treatment on off axis response curves.
