nanoFlash FAQs

No; not in the traditional sense. When recording, you need to genlock the cameras.
Since nanoFlash locks to the incoming HD/SD-SDI source, it will also be genlocked
automatically. During playback, multiple nanoFlashes can be genlocked via a master HD-
SDI distribution amp.
24. How can I monitor the video?
nanoFlash has both HD/SD-SDI and HDMI outputs which are simultaneously active
during record (loop-thru) as well as playback.
25. How can I monitor the audio?
Audio levels are displayed on the LCD panel (2-Channels, -60 to 0 dB). nanoFlash also
has analog audio out (via a 3.5 mm jack), which can be used with headphones or
speakers (output limited to about 88 mW into a 16 ohm load). Also, this audio output can
be configured for consumer line-level output (-10 dB).
26. Will nanoFlash support 4 or 8 channel audio?
Yes, nanoFlash support 2,4 or 8 channels of embedded audio.
27. What are the analog audio I/O choices?
Input: consumer line level (3.5mm jack) in either mono or stereo format, unbalanced
consumer line level (-10 dB) or balanced microphone input (without bias voltage applied).
Output: consumer line level or headphone output (3.5 mm jack).
One should monitor the audio input levels and be prepared to reduce the consumer line-
level input at the source if the level is too high.
28. Can the analog audio be recorded with the embedded (SDI) audio?
This capability, which would create a 4-channel recorder, is planned as part of the 8-
channel audio firmware update, scheduled for mid 2010 release.
29. Can the audio be delayed / advanced relative to the video?
Not at this time.
Compact Flash Media / File Formats
30. Why Compact Flash?
Compact Flash (CF) is an industry standard memory card widely used in digital cameras.
CF utilizes solid-state NAND Flash memory, and is extremely rugged (no moving parts),
consumes very little power, is very reliable, low-cost and is available with a lifetime
warranty from many manufacturers.
31. Why Compact Flash instead of SDHC?
SDHC cards, until very recently, were limited to about 50 Mbps and therefore unusable for
high-quality, high bit-rate professional video. SDHC is a 4-bit bus, while Compact Flash
uses a 16-bit bus for data transfers and therefore has higher potential bandwidth.
32. Why Compact Flash instead of a Hard-Disk Drive?
