UsingPS8 & 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. Singleidentical cables can thus be used to loop through combinations of up to 2 x PS8 & 1 x LS400 in no particular order.PRODUCT FEATURES PS8 LSub 400Components : LF [VLF] 1 x 8" (20cm) Shielded Neodymium 8 Ohms driver 1 x 12" ( 30cm ) long excursion 6 Ohm driverHF 1 x 1" Shielded Neodymium throat driver + Low Distorsion,Constant Directivity Asymetrical Dispersion Horn.-Height x Width x Depth 406 x 250 x 219 mm (16"x 9 7/8"x 5 5/8") 338 x 500 x 406 mm (13 1/4’’x 19 5/8’’x 16")Weight : Net 7.5 kg (16.5 Lb) 19.5 kg (43 Lb)Connectors 2 x NL4MP SPEAKON 4 pole 2 x NL4MP SPEAKON 4 poleConstruction Baltic Birch Ply finished with structured black coating Baltic Birch Ply & structured black coatingFittings: Handles - 2 Metal HandlesFront finish Perforated steel grille -Flying Points & Fixed Installation Threaded inserts are fitted as standard to all cabinet surfaces forconnection of mounting accessories-Stand fittings Built in Stand Fitting, 35mm (1"3/8) Internal Stand Fitting on Top (35mm, 1"3/8) accepts amast supporting 1 or 2 PS8's.PRODUCT FEATURES PS8 TDControllerAudio Inputs Two L&R Audio inputs.
