hi all
can anyone help me with the setting and tuning of nexo ps15 and ls1200 3way setting and crossover frequency by using PA+?

    As I said before Nexo would be the place to get the suggested setups.. I'm a bit concerned here because Nexo is a very processor heavy speaker.. the DRPA+ might not have the horsepower to even implement the setting if you were to get them from Nexo. There really isn't a lot of traffic here get you much exposure either. I am sure if you contact Nexo they will indicate that they have a dedicated processor for these (especially if they are 3 way passive).

    If we knew more about these we could perhaps help you roll your own, and maybe Dennis has worked with these.. but other than that this is probably not your best resource unless you can get us some Nexo specific crossover information to implement...

    The PS15 must be used with the processor for EQ and protection. Doesn't sound good at all without it. the processor drives stereo passive and optional sub out. If you run it active, it only does mono.
    The protection also uses sense cables and is very comprehensive.
    Note that these fellas need a lot of juice. We use PL4.0.

    : Hi. Maybe I'm misreading this but from, what I can understand you have to have the processor for the PS 15 even for the passive mode. Doesn't make sense to me. Is this correct or have I misunderstood what I've been reading. I'd like to have a pair but want to run them passive and don't want to spend 2k on a processor.

    Nexo PS15 Controller

    The PS15 TDController MkII is an advanced analogue processor that allows the PS15 Loudspeaker and optional PS15Bass and LS1200 Subwoofers to achieve exceptional performance from such compact packages.

    The PS15 TD MkII provides crossover, sensed amplifier control and system equalisation optimised for the PS15, PS15Bass and LS1200. The PS15 TD MkII also features user selectable passive or active (bi-amp) operation of the PS15 Loudspeaker. One PS15 TD MkII has two inputs and three outputs, including summed sub out, minimising installation cost and complexity. Like all Nexo processors, the PS15 TD MkII provides precision dynamic, voice coil temperature and diaphragm displacement protection through the use of selective Voltage Controlled Equalisers (VCEQs), reducing levels only at frequencies when and where necessary.

    PRODUCT FEATURES

    - Audio Inputs: Two L&R Audio inputs. Electronically balanced, 36 kOhm. Two XLR-3F connectors.
    - Sense Inputs: Three Amplifier Sense Inputs, 180 kOhm. 6 Pole Removable Strip Terminal. Passive Mode, PS15 L&R,LS1200). Active Mode, PS15 LF and HF, LS1200.
    - Audio Outputs: Three audio outputs. Electronically balanced, 50 Ohm. Three XLR-3M connectors. Passive Mode, twoPS15 L&R, one Mono (L+R) LS1200. Active Mode, one PS15 LF, one PS15HF, one Mono (L+R) LS1200
    - Indicators: Speaker Protect LED’s. Amp Sense & Peak LED’s. Active Mode LED. Power ON LED.
    - Dimensions: 1U 19� Rack. 210mm (8.5�) Depth
    - Weight : 3.3 kg (7.3 lbs) net

    SPECIFICATIONS

    - Output Level: +20 dBm Max. +19dBm Max on 1kOhm
    - Noise: -88 dBm (22 Hz - 22 kHz, UnWeighted)
    - THD+N: < 0.03% Typ. 0.05 Max for +18dBm Output
    - Power Supply: 110/220 Volts (internal wiring), 50/60Hz. Earth-Lift (back panel)

    SYSTEM OPERATION

    - The PS15 TDController MkII is precisely matched to the PS15, PS15BASS & LS1200 cabinets and includes sophisticated protection systems.Use of either product without a properly connected Controller will result in poor sound quality and may damage the components.

    - Active two-way operation of the PS15 Loudspeaker in passive mode or three-way operation in active mode with the LS1200 Subwoofer is included in the PS15TD MkII.

    So what are you implying here Mr. Dra?
    Nexo would be the place to get the suggested setups.. I'm a bit concerned here because Nexo is a very processor heavy speaker.. the DRPA+ might not have the horsepower to even implement the setting if you were to get them from Nexo.

    Nice digging though!!! :mrgreen::mrgreen::mrgreen::wink:

    Very confirming to your point I thought. 8)
    Actually, not much digging at all.
