ENR-1.2*/ENC-1.2*: to use with some type of camera (ex. Canon® C300, Canon® XF305, Sony®
Pmw200, Sony® Pmw300, Sony® PmwF5, Sony® Fs7, Nikon® D600 or Nikon® D800, Canon®
SD mark3...) which accept a signal with reduced dynamic. This type of expansion doesn't add
artifacts to the signal and allows to have a less noisy signal. It allows to improve the quality
of the audio registration (compared to the ENR/ENC standard) increasing the S/N ratio up
to 15dB.
To use these expanders, it’s necessary to set ENR on the transmitter and ENR 1.2 on the
receiver or set ENC on the transmitter and ENC 1.2 on the receiver.
ENR-1.2 it’s used for the optimization of noise, ENC-1.2 it’s used to optimize the voice.
NOTE: The compander of the receiver must be the same as the transmitter
MCR54 core is a power digital audio processor that, besides an unbeatable audio quality and
flexibility, can emulate most expanders systems on the market. On this menu you can setup the
audio expanding chipset emulation. ENR is emulating the Philips SA572 and PTT digital data of
Wisycom transmitters. Other setups can be loaded on request.
