What is REL high level input?
The high-level, unbalanced, dual-channel (stereo) input is via a Neutrik® Speakon® connector which is connected to the power amplifier’s left and right channel speaker terminals. This has the advantage of ensuring that the REL receives exactly the same signal as the main speakers.
Where do you place a REL subwoofer?
Because RELs are engineered to produce foundational low bass, it is beneficial to place a single REL into a structural corner at the front of the room, immediately behind the main front speakers. If you have a choice of corners, select the corner that is either built from stronger material (Masonry vs. Sheetrock).
