JBL PB10; does it have a high pass cross-over on the outputs?

[Jimmy154]

Here is the manual: JBL PB10 Subwoofer Manual

I don't think it's any help though.

There are 200uF coupling capacitors used between the input + binding post and the output + binding post. So in a sense, yes it will form a hi-pass filter with your speaker. However, the cutoff frequency will depend on what the speaker impedance is per given frequency.

Cutoff frequency = 1/(speaker impedance x .0012566)

If I understand correctly, the cross-over works for the high level outputs only if a high level input is connected, no? So if I plug in the RCA input the high level output does not work or it does not output with a high pass cross-over?

 

[Jeb-D.]

The high level outputs are driven directly by the high level inputs (but passes through a coupling cap). The internal amplifier for the subwoofer does not power the high level outputs. Think of the high level inputs and outputs as a pass through that the subwoofer amp is able to tap an input signal off of.

If this description isn't clear, refer to the user setup information supplied in the owners manual.
