For those with Helix DSP.3 experience …
1. Re: Multiple selectable "Sound Setups" - Am I correct in understanding that a sound setup saved to memory includes absolutely every setting available in the software? IOW, one saved setup can include IO routing to a center speaker output (configured as "realcenter") and be tuned for least-compromised multiple-seat listening, while a second saved setup can omit IO routing to a center speaker output and be tuned for optimal driver-only listening without the center speaker being used at all.
And, if I'm only needing to switch between these two setups as a regular thing, the URC.3 controller can handle that without the need for the full-tilt Director, is that correct?
2. Re: "realcenter" - I am assuming that "realcenter" does a heckova job in providing a least-compromised multiple-seat listening experience, but that a 'no-center' configuration tuned specific to a driver-only provides the better imaging for a driver-only situation. Has that been your experience?
4. Re: Line-level and High Level input - it appears that the DSP.3 is unique among Helix' to date in that it allows simultaneous line-level and high-level inputs as long as they aren't on the same input channel. BUT, there's one gain adjustment and affects both the line-level and the high-level inputs (presumably within the relative voltage range applicable to each). So, to actually use both line- and high-level inputs one must find a gain setting on that single adjustment that works for both (and may not be optimal for either). Is that correct?
^this question in the context of an OEM HU where all of my music outputs to the DSP.3 inputs are high-level but I am able to tap a line-level source for my Navigation Voice Guidance absent any music (all of the music outputs are muted by the OEM system when the NAV Voice 'speaks'). IF I can introduce that Nav Voice as a line-level input it would be convenient. Yes, there is a workaround involving the use of one-channel of an amp to boost the Nav Voice to high-level and tweak that level at the amp (a JBL MS-A1004) to coordinate it with the OEM HU outputs.
Thanks In Advance for helping me understand the nuances of the DSP.3 .... I thinks it's looking like a most promising choice for my new vehicle requirements.
