Review: Rio Volt MP3-CD player

Author: JT Smith

By Jeff Field

When I reviewed the Mambo-X MP3 player, I wasn’t
very impressed. It did the job, but it was lacking a lot of features I thought were pretty obvious. It’s been a few
months since that review, and newer players are out, with better features. The Rio line of MP3 players has been around since the beginning, and it
is no surprise that Rio parent company Sonicblue has a CD-MP3 player. So, how does it stack up?
The unit
The first thing I noticed out of the box was how sleek the Rio Volt unit was. The Mambo-X looked like my clunky old Discman, while
the Rio looks very compact and modern; in fact, it even fit in my pocket rather well. On the face of the unit are the controls for play,
stop, skip/search, program, mode, equalizer, volume, navigate and +10 (which skips along 10 tracks). To be
fair to the Mambo-X, there has been a new model since my review, but the difference in design between the Mambo-X and the Rio is amazing. On the Rio, there is a hold switch on the side of the unit and on the underside is a switch you use to set the length of shock protection on CDs. Regardless of this setting, MP3s always have 120 seconds of shock protection. I was unable to get the unit to skip under MP3 or AudioCD use when shock protection is set to 40 seconds.

Battery life on the unit is advertised as up to 15 hours on two AA batteries. In my experience,the actual battery life is 13 or 14 hours, but it is still plenty of juice for two AA batteries. One feature I find interesting about this unit is that while playing songs, it will spin the CD down and play from the buffer, meaning it will not skip and it does not have to use power for the motor. This greatly helped Sonicblue increase battery life on the unit, and I would suspect other players will copy this feature soon.

The remote
The remote on the unit, while not an Ir remote like on the Mambo-X, is quite good. It attaches as a pass-through between the player and the headphones. The remote has play, stop, search and skip functions, as well as its own hold and equalizer buttons. This is nice when used with the included carrying case, which has a hole in it for the remote and headphones to fit through, letting you use the remote (which is clip-on) while you jog or do anything else where you can’t access the player directly. What is missing from this remote is the skip 10 button (which would be so much more useful than an equalizer) or direct-digit access to tracks. The remote is useable, but not as convenient as it could be.

Included accessories
Included in the box were an AC adapter, the getting started guide, earbud headphones (not very good earphones, but they are earphones nonetheless), Windows and Mac “audio management software,” two AA batteries, the remote, the carrying case, and the unit itself. The carrying case can slide onto your belt and is made of a flimsy material. If you want actual protection for the unit, rather than just something to hold it, you will need to look elsewhere, but for someone who is just going to jog, bike or walk with the unit, the carrying case is adequate.

Limitations
The limitations on the Rio Volt are significantly less than those on the Mambo-X I reviewed. The Rio Volt can read multisession CDs and can handle bit rates up to 320Kbps, two functions the Mambo-X could not do. The Rio Volt supports several audio formats, including MP3, WMA (Windows Media, not something relevant to Linux users), and AudioCD, with the ability for more formats in the future with upgrades.

Upgrades
This is another feature on the Rio not found in the Mambo-X — with the Rio, you can download Firmware updates. The unit I got had Firmware version 1.08f, and I went to see if there were updates. As it turns out, the latest update is 2.00, which adds new features and fixes issues with the player.

I downloaded the Firmware update, but the problem is the Firmware update is a self extracting Windows EXE, so you either need to run it through WINE, or find a Windows machine. Once you do get to the file needed (IMP-100.HEX), you burn it to a CD-RW (burning it to a CD-R would be wasteful because you need only use it once), put the CD in the unit, and hit play. The unit will start upgrading the Firmware, and then shut off. Remove the CD (and erase it so it doesn’t try to upgrade every time you insert that CD) and play as normal. The only thing to be careful of is power interruptions. I recommend you use the AC adapter because if the batteries die while upgrading, you can render the player inoperable.

Sound quality
Using my own headphones, rather than the ones included with the player, I got good sound quality playing back 128Kbps and 192 Kbps MP3s. I could not notice the difference between the same track on a CD and the MP3 file. I was quite impressed by this — I fit 150 songs in place of the usual 10 to 15 on a CD, and I did it with no noticeable reduction in quality, at least to my ears.

Conclusion
While I was hesitant to recommend the Mambo-X to people, I feel no such reservation with the Rio Volt. I am purchasing one, and I feel justified recommending it to others. With excellent features and a good design, it is a player you should consider buying. It is a little more expensive than some other players, such as those that use flash memory to store data, but in the end I think it is a better deal, especially when compared to flash storage devices, which do not hold nearly as many songs. The RioVolt can be found for around $150 on Pricewatch.

But behind those frustrations is a lack of compelling applications that might convince users to tackle the medium’s other weaknesses. Now, platform provider Pure Matrix is suggesting that if compelling applications are what users need, they should build ’em themselves.”

The IT faithful still attend USENIX Annual Tech Conference

Author: JT Smith

The USENIX Association announced today
that its signature conference suffered no change in attendance despite
a
sagging technical industry.

Shrinking training budgets and massive layoffs have depressed
conference
attendance industrywide, with many events reporting drops in
registration anywhere from 15 to 30 percent from last year. However,
the USENIX Annual Technical Conference, held late last month in Boston,
reported only a five- percent decrease, bringing in over 1,750
technical
professionals. International registration totaled nearly 14 percent,
with 35 countries represented in attendance demographics.

“The strength of this conference is a very important factor,” said
Yoonho Park, USENIX Annual Tech 2001 Program Chair. “We were certainly
in an area where USENIX makes a lot of sense for a lot of people.
People have been coming to this conference for a long time and I’m sure
they made a ruckus to their managers about attending this year.”

“Not everyone was employed,” added Carla Ellis, Annual Tech 2002
Program
Chair. “They came regardless.”

The conference provided an intellectually challenging program with two
tracks of technical research presentation, including the popular
FREENIX
track, sessions dedicated to open source research and advances.
Presenters included industry luminaries such as Keynote Daniel Frye,
Director of IBM’s Linux Technology Center, Security gurus Steven
Bellovin and Avi Rubin, and Compaq’s James Gettys. Longtime USENIX
members, Avi Rubin, Margo Seltzer, and Keith Bostic also announced the
release of their new books at this conference.

“We orchestrated it so that my book signing would be right after my
invited talk,” said Avi Rubin, a member of USENIX Board of Directors.
“I
really think this is the right place to do promotions considering the
combination of the size of the audience and the technical bent that
they
have.”

The Annual Technical Conference is the first of USENIX’s major annual
events, which include the Security Symposium in Washington, DC, in
August; the Annual Linux Showcase and Conference in Oakland in
November;
and the unique conference LISA 2001, The Systems Administrator’s
conference.

“If you want to know what is going on in the industry in the next three
to five years, go to a USENIX conference and hear what the argument is
in any given year,” said Clem Cole, FREENIX Program Chair for Annual
Tech 2001. “This is where industry and research begin to come
together.”

Detailed information on upcoming USENIX events is available on the Web
at www.usenix.org/events.
