Hello,
can somebody tell me what kind of device we need?
or how to set a fp10000 parallel (not bridged)
I need a device that can split the signal after the speaker management into multiple amp channels. something like a y-kable but without loss.
normally I would turn the amp into parallel mode, but I don't know how this is possible with ours (prokustk fp10000q)
and the manual does not show such an option.
currently are we using 4 channels of our DSP just for the bass. but it's mono and all have the same settings. and we could use the free channels
we are amateur but constantly tinkering on our soundsystem
we are currently running a system of 4-16 kickbins, 2 syntripps as tops,
the tops are powered by
crown XS 500 and 900
for the kickbass we are using
up to 16 dynacord fe100lo
sometimes we add 2 bins of the 18sound horn sub
for deeper frequencys
thanks for the help

Hi,
Not sure i totally get what you are asking, but if you want to split line level signal ( one input to multiple output) then you need... a splitter! 😉
This one should do the trick:

Do you want to split digital signals or analog signals? And how do you want to split them, by frequency range, or something else?
Also, are you aiming to get stereo?
In addition, a Y-cable doesn't necessarily have loss. If you have a low impedance source and high impedance loads, why would you have loss?
okay, I thought so. I was confused because some of them are for mikrophones.
but thanks for the recommendation.
yeah and no the bass can stay mono. but the tops are 2 way.
they are supposed to be stereo. with only two free dsp channels I can't do that
the berry has 160 ohm output and the fp10000 20kohm.
that should work
what is the math behind that?
thank you, too
Hi,
Yes some are dedicated to mic signal, others are ok with line too.
The formula for attenuation is the same as for a 'simple' passive attenuator ( this is a 'bridged line' kind of transmission schem, you transmit a voltage to next stage not power) except you have multiple input impedance (of next stage) in //, so if input impedances are the same value it's 1/4 the nominal impedance. Eg: 20k input impedance of next stages and you need 4 of them in parallel, impedance to be used in the math is 5k. If impedance vary between input it can get a bit more complicated.
In other words it's a classic L pad attenuator but with 1/4 the nominal impedance of following stage input.

You talk about stereo for low end? At which frequency do you xover the bass bins? Cause it's questionable if you'll gain anything in stereo ( can even be less good than in mono!).
To have a monoed sub can help to have strong solid bass ( as there is less chance phase anomaly between L/R will cancel themself acoustically around the dancefloor area), it was the norm to mono everything below 80/300hz with vinyl cuting lathe ( because they can't cut out of phase signal in low end ) and it was a trick used in club's PA too.
If you have concerns about attenuation you could still implement an active version of splitter with buffering. The drawback will be it needs some psu but otherwise it'll copy input signal 1/1 (well with maybe 0,01db attenuation) and will lessen concerns about output dsp stage capability to drive long lines ( buffer takes the 'hardwork', dsp output stage have only to drive the nominal input impedance of splitter's buffer input stage ).
Could be easily done with That 1246 input receiver and 4x That 1646 line drivers ( if you need balanced impedance line).
1646 are 5k input Z so the 1246 would have to drive 1250 ohms which is well into it's capability and will offer something into the 50k input inpedance ( balanced) and will accept unbalanced too ( circa 20k ohms input Z). Likewise the 1646 can drive both unbalanced/balanced impedance line ( this serie of chips are designed to behave the same as transformers).
If you need unbalanced line most serious opamps configured as buffers would perform great too.
It'll probably cost a bit more than a commercialy availlable passive unit though, but it can be worth it.
I would not use a Y cable to drive bass bins of PA... not secure enough to me and could pickup nastys around. But ymmv.
Syntripp? Must sound good!
