SYSTEM OPERATION
Electronic Controller The PS15TDcontroller is precisely matched to the PS15 & RS15 cabinets and includes protections. Using PS15 & RS15
without a properly connected PS15 TD will result in poor sound quality and can damage the components.
Dispersion configuration After dismounting the front grille from its fixings, the HF Horn can be rotated in 4 positions for dispersion configuration.
SubBass The PS15 can be used without optional RS15 Subbass. Active two-way operation with RS15 is included in the PS15TD.
One RS15 matches 2 x PS15, additional RS15 may be used for enhanced LF capability.
Speaker Cables PS15 are wired 2-/2+ on Input Speakons in Passive Mode
PS15 are wired LF 1-/1+ & HF 2-/2° on Input Speakons in Active Mode
Please refer to RS15 User Manual for RS15 for RS15 connection.

[a] Response curves & data : Anechoic Far Field for the PS15 + PS15TD. Half-Space Anechoic radiation for the RS15 + PS15TD.
[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 ±3 dB range. Data are for s pro recommended amplifier combinations. Peak
SPL is at clipping of recommended amplifier. Measurements made with PS15s in passive operation mode.
[c] Directivity curves & data : obtained by computer treatment on off axis response curves.
