The MTP40S Lite on the website shows the limiter as one of the features currently available. Remember, the MTP40S has 80dB of input gain range which means tons of headroom. The MPR30-ENG also has the ENR1.2 expander mode specifically designed for DSLR cameras use. This expander mode reduces the dynamic range of the output so that the DSLR inputs can not be clipped.
