Re: dINgO Pup kit BUILD THREAD

Thanks. Went with the 48V power pack and 24v zener diodes in the end. I've used 4mm ply board for the front/back panels of an encosure (which houses the dingo pup), could I use a metal DC jack given no continuity to the remainder of the enclosure? Would I need to chassis ground the XLR input grounds...

Re: dINgO Pup kit BUILD THREAD

Hi Joe, similar to a prior question. Is it fine to use a standard 18V plug pack? If yes, would the included 24v zener diodes be fine or would I need to go a different value?
Cheers!

Hi Joe, is there a parts list available for the Palpigrade yet?

Re: Regurgitator kit Build Thread

OK these are exactly what our dingo pup kit was made for with its balanced in to unbalanced and unbalanced to balanced amp on one pcb. With Fet input opamp you can set the input impedance by one resistor to 1Meg or More. This can also be done in compact form with our Tardigrade unbalanced to balanc...

Re: Regurgitator kit Build Thread

Best to let me know exactly what you are driving into the regurgitator so I can see the problem clearly. Like impedance out and max unbalanced output level and max balanced level you want out? Hey Joe, thanks again for your time. I'll either be patching from/to the balanced outs/ins of my Antelope ...

Re: Regurgitator kit Build Thread

Remember the input impedance of regurgitator is 15k balanced and 7k5 unbalanced so driving from a much higher output impedance device will drop lots of level. Ok, and there'll still be significant loss of signal despite the +18dB gain? Also, is there any way to counter this level drop with this kit...

Re: Regurgitator kit Build Thread

8pack regurg with 8 x NE5532A idle current @ +/-18v is roughly 80mA. So if you are only driving 10k loads then 150mA to 200mA is heaps. Thanks Joe! I'll be driving the following loads: IN: 1 x 6.6kΩ-47kΩ (selectable) IN: 1 x 40kΩ IN: 1 x 1MΩ IN: 1 x 47kΩ OUT: 2 x "more than 5kΩ" OUT: 2 x 600Ω OUT: ...

Re: Regurgitator kit Build Thread

Hi there and thanks Joe/Rob for making this kit! I'm wondering if anyone can help answer a few questions that I have: 1. What is the recommended method of mounting the PCBs to an enclosure? I don't see any mounting holes and was wondering how most people were securing the PCBs - aside from the chass...
