Audio input gain and attenuation
N • The set gain (G) and attenuation (g) commands are case sensitive. The increment, decrement, and read level commands
are not case sensitive.
• 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.
