environment matches that of the mixing room. This control operates in addition to the
dialogue level control, and is best thought of as the final volume setting on the
consumer’s equipment. This value can be determined by measuring the SPL of pink

Room Type
The Room Type parameter describes the equalization used during the final mixing
session at the studio or on the dubbing stage. A Large room is a dubbing stage with
the industry standard X-curve equalization; a Small room has flat equalization. This
parameter allows an amplifier to set the same equalization as heard in the final mixing
environment.
