Cristi, what is the output voltage of the BIPS board?

Thanks

Cristi 26th January 2010 05:47 AM

the BIPS has by default unity gain, so the output voltage is equal with the input. if you want to use-it as a preamp, few resistors must be changed.

soft start board
 
Hello Cristi,
I have used the board before a 500W transformer and followed by 160 000 uF of line filtering and a solitary Cl 60 thermistor. I am planning to add another 40 000 uF of line filtering.
Will this be an issue with the soft start board?

BTW have you mailed out the speaker protection board to Malaysia ?

Thanks

you can add another 40mF capacitors, but if the transformer isn't able to deliver the required current when charging the capacitors you might need to increase the timing for the delay by changing the 10uF capacitor with a bigger one. be careful with the rectifier bridge, if can handle the inrush current, without afecting the reliability.

i sent the speaker protection already, it should arive by now. if not, then just after the chinese new year. let me know when you get it.

Hi Cristi,
Many thanks fro the reply.

Hi Cristi,
if I have balanced signals, should I use the Balanced Input Phase Shifter to input your amps? In the picture of the BIPS I see only male XLR connectors (usually used for outputs).

Cristi 6th March 2010 06:16 AM

the BIPS can be used for both balanced input signal and unbalanced input signal. there are also unbalanced inputs, 2 RCA connectors on the board.

speaker protection board
 
Hi Cristi,
I got the board yesterday. thanks .
What is the ac input for the module ? will a 12 V ac from a 10W transformer do ?
thanks
