A:Answer Yes and No, if ur looking for a bass up or down then no. Each speaker can be raised or lowered independently in the menu. This is a high end receiver and should have a sub attached, I have two.
The amp let’s u set up the crossover levels to determine the bass frequency crossover to each speaker and what’s diverted to the sub(s)
I have the rx-a4a connected with 2 Paradigm performance series towers, paradigm center, M&K MX 12 sub, Klipsh Premier 12 sub and 4 Cambridge audio Minx min22s for rear surround and high overhead up front for front Dolby Atmos. Have it connected to an LG G1 77”. With recent firmware updates everything seems to be working really well. PS5 looks and sounds amazing.
