Individual controls, offering finer trim adjustments (in 0.1 dB increments) for the right and left channels and group
master offsets are present in the DSP and available through software control (see “DSP Configurator Program”, in
chapter 5, “Switcher Software“). The results of these controls are not shown in the responses below.
