Page 18: Input-To-Track Routing
Input-to-Track Routing The 702T uses a fl exible routing scheme to assign inputs and tracks for recording. The input matrix allows any input to be routed to any recording track. Multiple inputs can be routed to a single track to create mono-mixed recordings. -

See Time Code section for more information about the 48.048F, 47.952F, and 96.096F rates. Bit Depths The 702T records at bit depths of either 16 or 24 bit. 24 bit recording provides greater dynamic range and addition headroom for signal peaks relative to 16 bit recordings. 24 bit recording (versus 16 bit) is a signifi... -
Page 21: Word Clock
Once a fi le is recorded its sampling rate and bit depth can not be changed in the recorder. The 702T does not perform sample rate conversion or bit depth changes. File conversion must be done in another environment, such as an audio workstation. -
Page 22: Link - Multi-Unit Linking
702T User Guide and Technical Information C. Link – Multi-Unit Linking The proprietary C. Link (control link) connection allows multiple 702T, 702T, 722, and 744T recorders to be connected and clocked together. The C. Link also enables the CL-1 Remote Control and Key- board interface to control the 702T with an attached keyboard or via switch closures. -
Page 23: Outputs - Analog And Digital
Outputs – Analog and Digital The 702T has two independent output buses , the Analog Output Bus (Bus 1) and the Digital Output Bus (Bus 2). Each side (left and right) of the two-channel buses are assigned audio sources indepen- dently, allowing the 702T to feed multiple audio devices with unique program content. -

Page 32: Time Code Hold Off
When external code advances, the 702T enters record mode automatically. When the external code is stopped, the 702T generator pauses and recording is stopped. If the external time code is removed the internal generator continues to run to preserve continuous time code. Useful for time code transmission over RF where RF “hits”... -

2 frames = 108 frames per hour. To sync the 702T to a video camera, fi rst determine if the camera is in drop frame or non-drop frame mode. If you, the DP or the producer are unsure about what setting to use, check with post-produc- tion, if possible. -
Page 35: Recording
Jam the camera from the 702T using a LEMO-5 to BNC adapter cable connected to the time code input on the video camera. Switch the camera to free run time code. The 702T time code should appear in the time code display on the camera. -
