The NAGRA VI has been designed as the natural successor to the NAGRA-D / DII multi-track digital recorders. Based on a totally new design concept, the hardware of the NAGRA VI is software dependent and can be adapted simply through software. Available in a choice of three colours ("Slate" grey, "Midnight" blue and "Burgundy" red) allowing owners of two or more recorders easily identify a particular unit. The NAGRA VI is supplied with two plastic "handles" which serve not only to protect the front of the unit from accidental damage, but can also be moved to their lower position and serve to tilt the recorder for a better viewing angle, and easier access to the functions when working on a table-top or sound cart. A carrying case and shoulder strap are also available for over-the-shoulder operation.
The NAGRA VI is delivered with a removable battery box containing a lithium-ion battery pack, a mains power supply and is equipped with a 120GB internal hard disk.
It offers six independent analogue audio inputs. Inputs 1 - 4 are equipped with traditional NAGRA microphone pre-amplifiers for dynamic and phantom +48V microphones. These pre-amplifiers are a combination of those developed for the NAGRA V and NAGRA-D and are without doubt the best audio inputs NAGRA has ever designed. An audio limiter can be selected for each of these inputs and these can be ganged in pairs if desired. These totally new concept input circuits offer the best specifications ever produced by any NAGRA in terms of pure audio quality. The four "In-house" transformers offer fully floating inputs for the dynamic microphones, giving a greatly improved signal-to-noise ratio. The remaining two analogue inputs are LINE level inputs for connection to other equipment supplying a line level signal, such as radio receivers. When set to the LINE position all 6 analogue inputs will accept up to +24dB. The two input connections (channels 5 + 6) double up as 2 AES inputs (A and B) when selected to digital input mode.
Zipper noise suppression
The NAGRA VI does not use traditional logarithmic potentiometers for the audio levels as were traditionally used on previous Nagra models. Today digital “encoders” are preferable because they do not suffer from “crackling” noise problems, and can be programmed to fulfill a multitude of different operations depending on the software program controlling them. Equally, even the graduation of the sweep is software calculated and can be altered relatively easily, rather than being created by the precision winding of the internal coils during manufacturing.
However, such encoders normally suffer from a phenomena known as the “Zipper” noise. The NAGRA VI benefits from a complex development in a suppression system used on every level control of the recorder. The end-result is that the potentiometers can be moved instantaneously and no digital zipper effect can be heard.
The potentiometers on the Nagra VI behave in exactly the same manner as the traditional logarithmic potentiometers used in Nagra analogue recorders but with the advantage of the precision offered by digitally controlled encoder devices, and hence an increase the perfection of all recordings.
The left side panel clearly shows not only the analogue and digital audio input connections, but also the external 4 pole XLR DC input socket, allowing the NAGRA VI to be externally powered from an external DC power source such as a car battery. The 5-pin LEMO SMPTE/EBU time code In/Out can also be seen as well as the two HIROSE connectors used for powering external accessories such as radio receivers. These two connectors can supply up to 1 A at 12V.
The right side of the recorder is where the removable compact flash card is located. A LED next to the slot indicates when the card is accessed. The stereo analogue outputs, and the main AES out as well as the second headphone connector can be clearly seen. Additional AES outputs are located on the 15 pin Extension connector. The Start / Stop terminal is a fader start (contact closure) command as found on other NAGRA recorders. Two USB (host / device) connectors are also located on the right side next to the card slot.
Recording medium and format
The NAGRA VI records to al 120GB internal 2.5" hard disk. An extractable compact Flash card is used to record a copy of the audio tracks depending on the users track selections. The NAGRA VI allows approximately 20 minutes of 6 track 48 kHz 24-bit recording per GB of available disk / card space. The compact flash card section is equipped with a "Hot-Swap" possibility meaning that the CF card can be removed and replaced while the NAGRA-VI is powered up, without causing any damage to the card or the recorder. The NAGRA VI records using Broadcast Wave File (BWF) format and is iXML compatible for the metadata making the files compatible with all modern post-production equipment.

The NAGRA VI is equipped with a sunlight-readable 3.5" colour TFT display with a resolution of 320 x 200 pixels. This specially designed high luminosity display is used to visually indicate not only the status of the NAGRA VI but also the bargraph modulometers, take number, time code and the current operating modes of the machine. When in the menu mode, the audio levels can be monitored using the LEDs on the front panel.
The NAGRA VI is equipped with two USB 2.0 ports. One is designed to connect the NAGRA VI to a computer for file transfer. The second is a "host" connection and although currently unused, it is planned to be used for connection of an external device such as a keyboard.
The internal time code system and all the internal digital electronics of the NAGRA VI are clocked by a crystal which is a "Stratum III" TCXO which has been artificially aged in an oven to maintain stability. This crystal gives a guaranteed overall stability better than ±4.6ppm over a period of 15 years throughout a temperature range from -20°C to +70°C. The drift due to temperature changes is less than 0.28ppm. This is the most accurate crystal ever used in an NAGRA recorder. The NAGRA VI will handle all the standard SMPTE / EBU frame rates as well as the 23.976fps rate for the HD format. All the frame rates can be pulled "up/down" for the NTSC markets.
