information request for High/Low Pass

till · 2nd April 2003, 01:12 PM

I need some information about the hopefully coming High/Low Pass.

- Will this device substitute a preamp?

(so i don´t need to build one now)

- What about the input impedance of the amps. I want to biamp with a Zen V4 and a lightbulb Zen. Need the amps to be same input imedance? Should i use a Zen V4 style input buffer p channel Fet in the lighbulb Zen to bring it to same input impedance like the V4?

- Whats the estimated date of publishing it?

- Will it work for my purpose, split at something between 500 to 1000 Hz second order with the planned amps?

Many thanks to the Passlabs crew, especially to cyclotronguy.

It's coming soon, position #2 in the queue.

The design should be flexible enough to accomodate a wide
variety of amp interfaces.

It won't function as a preamp if you need a lot of gain.

Ordinary filters like the ones you mention are no problem.

Thanks for information!

So it makes no difference if i build the lighbulb Zen with or without an input bufferFet in this applikation?

I don´t think i will need too much gain, source is CD and i´ll use lightbulb Zen for the TAD2001 horns.
