    Meters within the DSP Configurator are peak-type meters, referenced to full scale, or 0 dBFS. For the DMP 64 outputs, 0 dBFS corresponds to +21 dBu, the maximum output level of the device. Maximum input level is +24 dBu. Gain from -3 dB to +80 dB is applied in the analog domain, while attenuation from -3 dB to -18 dB is applied in the digital domain.
