Audio inputs
音頻輸入

The Seven offers two analogue audio inputs and a single stereo digital input. It will record in PCM linear audio at sampling frequencies up to 192 kHz or in MPEG-1 layer II compressed audio formats if the compression option is installed. The inputs are equipped with traditional Nagra microphone preamplifiers for dynamic and phantom +48V 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 10V dc supply voltage on the AES input. The analogue LINE input will accept up to +24dB allowing it to be connected to a standard audio mixer in the field.
納格拉7提供了2組類比音頻輸入跟一個立體聲數位輸入. 他的錄音品質 192 kHz 取樣率的PCM, 如果有安裝壓縮功能的話,可以支援MPEG-1 layer II 壓縮格式.
納格拉7配有傳統納格拉麥克風前級擴大機可讓動圈式跟幻象+48V 麥克風使用, 並且提供了可調靈敏度的範圍,皆能使用大多數的麥克風. 納格拉7在AES 輸入的10V 直流供電下同樣可以使用AES-42 麥克風. 可支援+24dB類比線性輸出以連接標準的現場混音器材使用.

Touchscreen
觸屏

The Nagra Seven has a state-of-the-art color touchscreen allowing greater flexibility in the display modes and screens, but also eliminating all switches which are the weakest link in modern electronics. 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.
納格拉7使用了先進的彩色觸屏允許在顯示模式或是屏幕下展現超凡的靈活性, 同時也避免了開關是近代電子產品最薄弱的環節. 在前面板上的觸摸屏幕上顯示了錄音機的音頻層級, 目前操作模式及狀態. 此螢幕為可在陽光下閱讀, 可進入操作整個菜單. 也提供了個人化進入各種編程的捷徑設定.

Media
媒介

The Nagra Seven is fitted with an internal 16GB micro SD flash memory, that can be increased by the user if desired. The main extractable media is an SD memory card which inserts into the slot on the left side of the recorder (see picture above).
納格拉7使用16GB SD快閃記憶卡, 客戶可自行更換擴充容量. 上方照片可看到在錄音機左側有SD記憶卡插槽.

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.
可使用Micro-AB USB槽來連接電腦傳輸檔案. 也可用此插槽來連接外部儲存裝置.

Editing and communication
編輯及通訊

If the optional editing option is installed, then graphic editing of the audio files is possible on the main display. Once the editing of the audio material is complete, files can be transmitted to the studio either over IP (through the ethernet connection using the File Transfer Protocol “FTP” connection) or via a GSM phone using 3G or by Wifi (if the option is installed).
如果安裝了編輯功能, 那就可以在主要顯示器上圖形編輯音頻檔案.  當編輯音頻完畢可使用IP (透過網路連接FTP)傳出檔案給錄音室或是透過GSM電話使用3G通信或是ＷiFi(要安裝WiFi功能)

SMPTE / EBU Time code
SMPTE / EBU 時間碼

The Nagra Seven has an optional internal time code board that works with all currently accepted frame rates including those for HD TV. It will handle both drop and non-drop frame rates, and will allow pull-up/down too.
納格拉7提供選配的內置時間碼板, 可適用目前所有可包含HD TV能接受的偵辨率. 他將處理drop/ non-drop 的偵辨率也能允許pull-up/down.

Start / Stop
開始/停止

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.
可遙控開始/停止.

Powering
電源

The Nagra Seven is supplied with a detachable battery box, into which 8 rechargeable “AA” cells can be installed. An optional lithium-polymer rechargeable battery pack, that will power the unit for about 7 hours is available. If phantom powering or transmission options such as WiFi or 3G are used the battery life will be reduced.
納格拉7提供了可拆卸電池盒, 此電池盒可使用8顆可回充的AA電池. 也可選購可充式鋰聚合物電池(約7個小時續航). 如果使用幻影電源或是使用WiFi 或3G傳輸, 電池續航力將會降低.
