Send LFE only signal into 7050A sub

Hi,

I know the 7050A sub is discontinued but I'm wondering if I can purchase a second-hand one to work with my system.

I currently have 3x 8030A for L,C,R and 2x 8020A for LS, RS. I drive these with a BlueSky base management controller (BMC1). The BMC has a LFE output and I'm wondering if it's possible to connect this to a 7050A? I'm currently loaning a 7050B and have connected the LFE from the BMC directly to the LFE in of the 7050B input and all lines up well with pink noise.

From the photo of the 7050A I see it has 2x XLR inputs, left and right. Do these have a low pass filter on them or do they just feed directly to the sub's amp/speaker?

Thanks

Hi,

7050A inputs have an 85 Hz low pass filter on them. So if you connect LFE signal to one of them, it won't have full range up to 120 Hz as in 7050B LFE input.

Many thanks for the reply. Time to save for a 7050B!

Thanks.
