Hello

Is it possible to configure the flex with 4 lowpass crossover outputs?   Manual states that when multiple sub outputs are required one should use the sub out on the receiver and bypass the crossover.    I don't have that option and want to use 4 subs using the crossover from the flex.
thanks

Yes. For each output you have the option to set one low-pass and one high-pass filter. These can be different for each channel.

Dear Ultrasonic
Thank you for your response.   Is it possible to instead get 4 channels of low pass filtering from 2 inputs?    I do not want or need the high pass.

I said 'option' to set one high pass filter on each channel. You don't have to . A major strength of miniDSP is that they give users control to do what they want. If you take a bit of time to read through the manual you'll find these options described in more detail.

Are you looking to sum the two inputs (left and right?) and send low-passed versions of this sum to each sub? Yes you can do this.

Thank you Ultrasonic

I have owned a 2X4 miniDSP for many years.    Previously I used it as a low pass filter and didn't use the high pass outputs.   I read through the manual again as well.    Since I have not yet bought the flex unit I cannot check the software but seems its much like the original units.  It has 2 inputs and 4 outputs but both outputs have one high and one low pass.   If you want more channels of lowpass you need to do that upstream and bypass the crossover section of the minidsp.    I do not want to sum anything.     I would like L+R in and  2X L+R lowpass out.

I'd suggest you'd be better off using a sum of L+R sent to all four of your subs personally. The advantage is that the in-room bass response will be the same no matter where the low frequency content is panned in the mix, and also increases the scope for a more even bass response through the use of 4 subs. Something to consider/experiment with, unless you're using an unusually high crossover to your subwoofers.
