> GLD DOES have HP on mixes. jim Participant Where? The closest you can get is to use the Low band as a High-pass, using up one of the 4 PEQ bands. Same as on my iLives. We’re asking to have the same capability as the channels: High-pass plus 4-band Parametric. -Mark ---

I just sold 2 X32 and bought a SQ6. I have been following the forums and fb pages and read just about every review/comment on the SQ line for several months. It seems like the A&H guys are extremely helpful at answering questions and clarifying issues, and it gives me great comfort to know they are only one message away from helping me with any snag I may encounter. BUT, I don’t understand why they will not provide anything on the questions of HPF on Aux and Matrix, or regarding the option of mono matrix. I mean, I think it would go a long way towards building a trusting relationship if we could get something on the subject, anything at all. Either “We are looking at implementing this request, but because of the XYZ platform/core/protocol/Canadian geese, we have not been able to come up with a stable solution that will not impact ABC. We are hoping to have these issues worked out in the upcoming X months.” OR… “We realize that several users have requested these features, unfortunately, A&H does not envision implementing them on the QU and SQ platforms.” At least we would know. I find this frustrating. Sorry, I didn’t mean to have my first post be a rant. I rarely rant. Now I have to go play with my shiny new SQ6! 🙂 ---

Quite possibly THE most requested feature but with the least interest from the factory. It is frustrating. ---

There’s an HP knob and switch on the front panel. They don’t work on buses. I consider this a bug. ---

> If it works as intended, it isn’t a bug. It doesn’t work at all, for no apparent reason. I get that companies leave off high end features in order to drive customers upward in their lines. This one makes no sense, though. People on A&H’s upscale mixers are more likely to be interfacing with systems that have accessible DSP. It’s the punters in the trenches that need HPF on our outputs. ---
