Overview
  • 1Description

The Seven 2-Channel Universal Digital Recorder from Nagra is a 2-channel recorder capable of capturing your audio in up to 24-bit/192kHz resolution. The Seven in controllable via its front-panel color touchscreen, which displays audio levels, operating mode, and device status, and allows you to program short cuts for personalization of your workflow.

The recorder features both analog and digital inputs, and 16 GB of internal memory that can be expanded via its microSD card slot or its USB port for USB flash storage. The USB port also allows you to transfer files or connect a keyboard to the Seven for data entry. It is powered by its built-in rechargeable battery.

Audio Inputs
The Seven offers two analog audio inputs and a single stereo digital input. It will record in PCM linear audio at sampling frequencies up to 192 kHz. The inputs are equipped with traditional Nagra microphone preamplifiers for both dynamic and phantom +48 V microphones and offer a range of switchable sensitivities to accommodate all common microphones. AES-42 microphones can also be used as the recorder can supply the necessary 10 V DC supply voltage on the AES input, which is also equipped with a sample rate converter.

The analog line input will accept up to +24 dB allowing it to be connected to a standard audio mixer in the field
Touchscreen
The Nagra Seven has a color touchscreen allowing flexibility in the display modes and screens, but also eliminating all switches, which can break after extensive use or if damaged. The audio levels, current operating mode and status of the recorder are shown on the touchscreen display mounted on the front of the unit. The screen is sunlight readable, and gives access to the entire menu structure of the recorder.

Various programmable "short cuts" are available giving many personalization possibilities
Media
The Nagra Seven is fitted with an internal 16GB micro SD flash memory. The main extractable media is an SD memory card which inserts into the slot on the left side of the recorder. An external USB storage device may also be connected to the USB port using an adapter interface cable
USB 2.0 Port
A micro-AB USB port allows the unit to be connected to a computer for file transfer. With an interface adapter, the same port can also be used to connect an external device such as a USB memory stick or computer keyboard for data entry
Start / Stop
A 3.5mm miniature jack socket is fitted for remote fader start/stop commands. This will allow the unit to be remotely controlled by a simple switch closure according to the current operational mode
Powering
The Nagra Seven powered by a lithium-polymer rechargeable battery pack, that will power the unit for about 8 hours. Rechargeable "AA" cells or even dry cells (in an emergency) can also be used in the supplied battery compartment
