Location Recorders | When Two Channels Won't Cut It

WHAT'S NEW IN MULTICHANNEL LOCATION RECORDERS 3/31/2010 9:21 AM Eastern

During the past few years, the industry has been flooded with portable “pocket” 2-track digital recorders. But in an increasingly complex world of location recording, two channels are sometimes not enough. Even on a relatively simple job—such as miking two characters for a film/video—the recordist may need to print two radio mics, a hidden set mic, a boom and a couple ambience mics for flavor/walla. Or, unpredictable levels may dictate the need to run several mics at different levels (with/without pad) or placements—even for a mostly mono source. When recording a volcanic eruption, space-shuttle launch or car crash, there’s just no chance to run it one more time to get the levels right.

If you’re seeking a fully portable recording solution—i.e., 100 percent DC-powered—options abound. While outside the scope of this article, there are also laptop-based solutions such as MOTU’s Traveler MkIII or Metric Halo’s Mobile I/O interfaces paired with recording software, such as Gallery Software’s Metacorder or other pro DAWs. Such a rig will certainly do the job, but it’s hard to imagine running down the street to follow fast-moving action with a laptop tethered to an interface.

This article takes a look at current offerings in location recorders, focusing on single-box, multichannel systems. Recorders are lighter, more reliable, better-sounding and more affordable than ever, making this a good time for some shopping.

Aaton Cantar X2 has a built-in 18-input mixer.

























The Aaton Cantar X2 ($13,995) provides 8-track capture to the removable, hot-pluggable internal hard disk or to the onboard DVD drive at 24-bit/96kHz resolution. The unit also has a built-in 18-input mixer and onboard M/S decoding, with nine rotary analog faders and six linear mixer sliders. The swiveling front panel makes for optimal viewing; in addition to its eight analog XLR inputs and two XLR outs, AES/EBU digital, timecode, word clock and FireWire are standard. The latter allows simultaneous recording to both the internal and external drives, while the analog complement includes five preamps and four line inputs. The 18 inputs (XLR mic/line and eight AES/EBU) can route to any tracks or outputs. Weight is 7.5 pounds, less battery.

Systems can be expanded with CantaRem (a compact 8-channel fader control surface) and GrandArcan, a Mac/PC application that remotely controls Cantar, displaying all recording, routing and monitoring parameters, plus metadata associated with each audio file. Cantar automatically generates a print-ready “PDF Sound Report” log that’s archived with the audio files. Circled takes, slate locators, track info, etc., can be entered from Cantar’s control panel, an external keyboard or a wireless (Bluetooth) connected PDA. Metadata is embedded in the AES31 description field that is readable by most nonlinear video editors.

Full 176.4/192kHz is supported for 2-track recording. Tracks are stored to BWF, and an Avid-compatible EDL file (ALE) can be created and edited. The PD606 records to the internal (user-replaceable) 1.8-inch 80GB hard disk and DVD-RAM discs. Simultaneous recording to both media is available either by mirroring or auto-copy. A Background mode automatically copies recorded audio from the hard disk to DVD when the machine is idling. The DVD drive can also write to DVD-R/RW and CD-R/RW discs for data copy/backup. The PD606 mounts directly to a host PC via USB, and a standard QWERTY keyboard can connect for file name editing.

Sync functions include a 9-pin ES-Bus remote port to lock a second PD606 for simultaneous recording, along with video/tri-level/word sync and SMPTE generator. Also standard is 0.1-percent Fs pull-up/down for video lock. Powering is via two IDX Endura batteries or external 12 VDC. Weight is 12.5 pounds.

Nagra’s VI ($8,200) is a 6-channel (four mic/two line) recorder that stores audio with 24-bit/96kHz resolution to an internal 120GB HD or Compact Flash media. The onboard mixer can take the four mic inputs to a stereo mix on channels 5/6, or five analog inputs to a mono mix on channel 6. The mic inputs have phantom power and limiters, along with a built-in matrix and two M/S mic decoders. Analog inputs 5/6 can switch to accept AES-3 digital signals. Audio is stored as Broadcast WAV. USB connectors provide access for external devices and the Nagra VI appears as a drive on a PC or Mac. A 5-pin Lemo port handles timecode in/out at standard SMPTE/EBU formats, as well as the 23.976 fps for HD production, and any frame rate or sample rate (44.1/48/88.2/96 kHz) can pull up/down 0.1 percent for the NTSC markets. The sunlight-readable, 320x200-pixel, 3.5-inch TFT display shows operating status, bar graph modulometers, take numbers, timecode and more. Power is via a lithium-ion battery or the 4-pin XLR DC connector. Two 12 VDC sockets power external devices such as wireless receivers. Weight is 8.3 pounds.
