Nomad Jukebox 3 info
I compiled this by scanning through search results using "JB3" as the criteria. Hopefully this'll help folks having all the info in one place. Anything to add? You know what to do!
- $200-300 | Standard JB3 w/ one internal battery, accessories, etc.
- $30-50 additional internal battery
- WAV (3 hr max record time per file)
- Digital: 1/8" optical
- Analog: 1/8" stereo
Bit and Sample Rate
- 16-bit only
- 32, 44.1, or 48 kHz
Battery & Power
- Proprietary lithium-ion internal
- Two battery bays
- Internal 1: comes with, gets ~3 hrs
- Internal 2: may add a second for another ~3 hrs or so
- External: 5V DC. Some people report problems running an external battery. Apparently, the device will sometimes lock up during or after charging the internal battery. Charging the internal battery while powering externally is unavoidable. Has anyone tried removing both internal batteries outright and running only on external power?
- Turn off the light and IR remote for optimum battery life
- Recommended: 1.20.06, above that is apparently buggy.
Feeding a digital signal
- Many people have reported audible problems - dropouts, glitches, etc. - when feeding the JB3 via a signal converter, i.e coax > optical, e.g. Midiman C02. Very few, if any, audible problems have been reported feeding it directly from an optical source like the UA5. However, no formal tests have been performed with respect to bit accuracy feeding the JB3 directly from the UA5. From my recollection of past posts, folks seem to be getting good results - i.e. no audible problems - using UA5 > optical > JB3. See Testing below for more info.
Stopping a file and starting a new one
- Instead of stopping, saving, and starting a new WAV file, try pressing the track forward button while recording. It saves the existing and starts the new one in one quick step (takes about 8 seconds).
Testing - updated 29 Sep 2003
- Both Jamie Lutch and Dave Klein have performed bit-accuracy testing with the JB3.
Jamie, if you're out there correct me if I'm wrong, but over long term testing the JB3 did not perform flawlessly when running "digital output > signal converter > UA5". It apparently dropped bits randomly. In this case, the setup does not appear bit perfect. However, some people are running this setup without audible problems (not necessarily bit accurately) and are happy with their results.
Dave Klein's testing
indicates the JB3 is, in fact, bit accurate when running "UA5 > JB3". This suggests the bit accuracy problems are related to the signal converter boxes used by Jamie and others. So perhaps best results are achieved feeding the JB3 an optical signal directly from the ADC, like a UA5, Apogee ADC, or Denecke AD-20.
Any others with feedback or testing with respect to sending the JB3 an optical signal directly from the ADC, please post!
