ProAc ER1 sub connections to Aktiv Amps

Hi All,

I just purchased a ProAc ER1 subwoofer and am wondering about the best setup.
I have L + R Low frequency RCA's directly connected to one set of the Pre outs on my Linn Wakonda Preamp and it seems fine.
I have a problem with the High frequency setup, the only other connection is the HF connection which is a Neutric(sp) connector.

Here is the problem.

I have 3 Aktiv Amps, Treble, Mid and Bass.

How do I connect the Neutric HF connector? Which amp?

Anyone have any ideas.

Amps are Linn LK100 x 2 and LK85
This is an interesting question. Sorry, but I don't have a clue. My best guess would be selling your existing sub and buying one of the Linn subs would be the logical solution.
I connected to the Bass amp with the Neutrik connection.
Using the HF connect made a noticable difference, the sub blends really well, highly recommend this sub, it is fast and deep. And adds a nice blend to music, Patricia Barber's Modern Cool, was cool.
