It is a vortex filter specifically designed to give ultimate protection against wind boom microphone noise This filter is designed to allow the Nagra VI to be used in the most difficult conditions on location The input filter on the Nagra VI is a hardware filter and is therefore not software programmable The reason for this choice is simple A software programmable filter is a digital filter in the heart of the digital part of the audio chain Wind noise coming into the pre amplifier will already have done its distortion and overloading directly in the pre amplifier long before it gets to the digital filtering stage The filters in the Nagra VI roll off 3db at 250 Hz and then at 12 dB per octave If an alternative curve is required then provision is made on the input circuit board to add capacitors accordingly and the necessary values can be supplied if necessary The filter can be activated for each pre amplifier in the input settings menu and this activation is indicated on the status screen by a green Tick below the bar graph level displays Chapter Part 2 The Audio 26 July 2010 The Mixer menu Mixer 2 3 Out 01 100 12 8 6 5 gt The internal mixer of the Nagra VI is designed as a 6 to 2 mixer where the inputs of channels 1 to 6 can be mixed and then sent to the outputs or recorded on tracks 7 and 8 In the Audio Mixer display the inputs can be selected one by one and the level and pa

40. I Certain compact flash cards particularly the cheaper brands may run too slowly for the Nagra VI depending on the recording mode being used It is recommended to always test a new card type using the media speed test menu before starting an important recording session The official identification number of a compact flash card can be seen in the Tools Software About menu We recommend formatting the CF cards with the Nagra VI to ensure that the cluster size is 2 which will render them faster Beware of Clone cards on the market which are often cheaper cards branded illegally The USB Drive The USB drive can be a generic USB mass storage device External hard disk USB key or even a DVD RAM burner It should be mentioned that there are hundreds of different types makes and sizes of such devices and the user should test the device first to be sure that it meets the necessary requirements for the Nagra VI Certain external USB Hard drives can consume too much power and are outside the official specification of the USB norm Such drives may cause the internal disk to crash when plugged in so it is strongly recommended NOT to connect such a device during a recording and to make trials beforehand to be sure that the external disk works The DVD RAM drive that we have used for the development tests is the model LG 201010 and is commonly available for around 65 We have tested several different USB keys of varying sizes without an
