NAS is Nissin’s newly developed 2.4GHz radio transmission wireless flash system. To compare with the traditional optical wireless transmitters, 2.4GHz radio transmission is less susceptible to angle and obstacle limitations, and has coverage up to 30 metres. Transmission channels and radio transmission IDs can be set to prevent misfiring in the event of signal interference on the same channel.
