RS GENERAL SET-UP INSTRUCTIONSPage 10 / 76 System Manual RS Series2.2 CablingNEXO recommends the exclusive use of multi-conductor cables to connect the system: the cable kit is compatible with all thecabinets, and there is no possible confusion between LF, MF and HF sections.Cable choice consists mainly of selecting cables of the correct sectional dimension (size) in relation to the load resistance andthe cable length. Too small a cable section will increase both its serial resistance and its capacitance; this reduces the electricalpower delivered to the loudspeaker and can also induce response (damping factor) variations.For a serial resistance less or equal to 4% of the load impedance (damping factor = 25), the recommended cable length is givenby:Lmax = Z x S S in mm2, Z in Ohm, Lmax in metersThe table below indicates these values, for 3 common sizes.Load Impedance () 2 2.6 4 5.3 8 16Cable section Recommended Cable Length1,5 mm² (AWG #15) 3m/10ft 3m/13ft 6m/20ft 8m/26ft 12m/39ft 24m/79ft2,5 mm² (AWG #13) 5m/16ft 7m/23ft 10m/33ft 13m/44ft 20m/66ft 40m/131ft4 mm² (AWG #11) 8m/26ft 10m/33ft 16m/52ft 21m/70ft 32m/105ft 64m/210ft6 mm2 (AWG #9) 12m/40ft 16m/52ft 24m/79ft 32m/104ft 48m/160ft 96m/315ftMaximum allowed length is 4 times recommended length.Example:Each RS18 driver has a 8 nominal impedance; in omni mode, both loudspeakers can be driven in parallel on one amplifierchannel, presenting therefore a 4 load impedance.Recommended length for 4mm2 / (AWG#11) is 16m / 52ft, maximum allowed length is 64m / 208ft.IMPORTANTLong speaker cables induce capacitive effects – up to hundreds of pF depending on the quality of thecable - with a low-pass effect on high frequencies. If long speaker cables must be used, ensure that theydo not remain coiled while in use.2.3 RS15 and RS18 recommended amplificationNEXO TD Controllers Recommended amplificationNXAMP4x1mk2 Powered Controller Bridged Stereo mode (2x2.6kW/4) 1 x RS15 in omni mode (drivers in //) per bridgedchannels1 x RS18 in omni mode (drivers in //) per bridgedchannelsNXAMP4x2mk2 Powered Controller 4 channels mode (4x2.5kW/2) 1 x RS15 in omni mode (drivers in //) per channel2 x RS15 in directional mode: 2 channelsNXAMP4x4mk2 Powered Controller 4 channels mode (4x4.5kW/2) 2 x RS15 in omni mode (drivers in //) per channel4 x RS15 in directional mode: 2 channels1 x RS18 in omni mode (drivers in //) per channel2 x RS18 in directional mode: 2 channels2.4 RS15 and RS18 setups on NEXO TD ControllersPlease consult nexo-sa.com for NEXO TD Controllers firmware information. |
