702 User Guide and Technical Information Quick Start Guide The 702 is an extremely powerful and fl exible portable audio recorder. Before recording, please familiarize yourself with the product. Several settings should be verifi ed or set based on individual recording needs. -
Page 6: Routing Inputs To Tracks
Routing Inputs to Tracks Before recording, inputs must be assigned to tracks. Each 702 input (1 and 2) can be assigned to the two recorded tracks (A and B). These 16 possible routing combinations are shown on the front panel with 4 blue LEDs. -

Page 15: Input Setup And Control
702 User Guide and Technical Information Input Setup and Control The 702 has two inputs and two record tracks. Inputs are selectable between analog or digital sourc- es. Analog inputs are connected with the balanced XLR connectors; digital inputs can be connected to either XLR Input 1 (AES3) or the BNC input (AES3id). -

Page 18: Input-To-Track Routing
702 User Guide and Technical Information Input-to-Track Routing The 702 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. -
Page 19: Selective Input Muting
Sampling Rate and Bit Depth When recording the 702 generates uncompressed, PCM audio WAV fi les in the Broadcast Wave File format at the user-selected sampling rate and bit depth. The 702 LCD calculates available recording time based on the sampling rate, bit depth, number of tracks armed for recording and the storage media’s available capacity. -
Page 20: Bit Depths
Once a fi le is recorded its sampling rate and bit depth can not be changed in the recorder. The 702 does not perform sample rate conversion or bit depth changes. File conversion must be done in another en- vironment, such as an audio workstation. -
Page 21: Word Clock
If the 702 is slaved to external word clock, be certain that the source is stable. Loss of the word clock signal during recording can cause the 702 to revert back to its internally set sampling frequency. If this occurs, the portion of the fi... -
Page 22: Outputs - Analog And Digital
Outputs – Analog and Digital The 702 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 702 to feed multiple audio devices with unique program content. -
Page 23: Digital Output Bus
40 dB. Headphone Output The 702 headphone output is a fl exible tool for monitoring audio in the fi eld. The 702 allows the user to monitor inputs, tracks, and post-record tracks in a number of combinations. MS stereo monitoring is also available in headphones. -

300 mS. While giving a very good visual indication of perceived loudness, VU meters gives poor information on actual signal peaks and are virtually useless for tracking to the 702. In VU mode, the front panel meter labeling is in volume units. -
Page 27: Peak Leds
Input Peak The 702 has a peak LED associated with each input. These LEDs illuminate when input signal reaches –3 dBFS. There is no user-adjustment to the Input Peak LEDs. These LED’s also function as indicators of input mute activity (see Input-to-Track Routing). -

Page 37: Compact Flash Recording Media
Compact Flash (CF) is an excellent portable storage medium for audio recording. Its speed and capacity continue to increase as its price continues to come down. The 702 records to and plays from CF cards as its primary storage medium. -
Page 38: Speed Testing
702 User Guide and Technical Information The 702 can format and use Compact Flash cards with a minimum capacity of 64 MB. There is no practi- cal limit to the maximum Compact Flash card capacity (2 TB). Formatting the CF rebuilds the FAT (fi le allocation table) and erases all audio and data fi les present on the card. -
Page 39: Qualifi Ed Cf Cards
Qualifi ed CF Cards Sound Devices does not specifi cally “qualify” CompactFlash cards for use in the recorder. From our tests of numerous cards—including medium from Lexar Media, SanDisk, and Kingston Technolo- gy—cards in capacities from 128 MB and above will successfully operate in the 744T. The unit will support up to 2 TB of data. -

CompactFlash, substituting the external drive menu selection for the CF. After recording to an external drive has stopped, it may take several seconds for the 702 to fi nish “house- keeping” on drive. This is especially true when recording to DVD-RAM disks, which generally have slower throughput than hard drives. -
