No, it is not recommended connecting the High Level and the Low Level simultaneously. These two inputs are run on the same circuit internally on the REL and will result in far too much gain. Connecting the High Level and Low Level can result in unnecessarily over taxing the REL circuitry.
When possible, connect the High Level Input to your main L-R amplifier channels and set the processor (in a home cinema system) to "Full Range" or "Large" in the Speaker Set-up Menu. Using the High Level Input and connecting to the speaker output terminals is one of the unique secrets of REL’s success and will maximize sub-bass performance.
The primary purpose of including a Low Level input is to allow for problem solving when a Class D amp proves to have a grounding scheme that even REL Pure D™ cannot solve or when using a single REL with a set of Monoblock amps. It is permissible and, indeed, highly desirable to connect High Level and the .1 circuit at the same time for surround sound applications.

I understand what you are saying. However, if I connect my main (front) speakers in high level connection with the low level also connected... for listening to music, the AV amp is in DIRECT mode and sends no signal to the low level connection. For home cinema, the AV amp has the front speakers as SMALL and only greater than 80Hz. While the filter in the REL subwoofers is set to 42Hz. So they will be connected to high level but the filter will mean there is no signal.
Would this be acceptable? It would mean that the REL would never receive both signals at the same time?
Hi, I have exactly the same question. Could you please answer if in AVR scenario using both connections (High Level for stereo direct and low leve for getting that LFE channel from Dolby mix) is acceptable?
Additionaly - it is class D based on TPA3251D2 (HEOS AVR).
