  We study the limiting behavior of Maass forms on Benjamini-Schramm convergent
sequences of compact quotients of ${\rm SL}_d(\mathbb{R})/{\rm SO}(d)$, $d\ge
3$, whose spectral parameter stays in a fixed window. We prove a form of
Quantum Ergodicity in this level aspect which extends results of Le Masson and
Sahlsten to the higher rank case.
