Review : Sangean
DAR-101 Digital MP3 Tabletop Audio Recorder
used with a HF / SW radio receiver for "off air" recording)
Recording a "off air" short wave radio catch or scanner activity for
enjoyment in years past was done to a compact cassette or even an
open reel tape machine. Using a personal computer is a more
modern way to store audio, but creates room noise if an earshot
of the receiver and not to forget the possibility of generated
radio frequency interference.
Professional "larger" stand-alone flash memory based recorders have
around for a few years, but at fairly steep prices. These are
near perfect as one can transfer the audio files to the computer
later, do any enhancement and/or editing to remove unwanted
segments to then burn to a compact disc (CD).
Indeed there are now lower cost flash memory based recorders
available today on the market, but these are in the pocket
variety so not so convenient for home use. Many do not even offer
a playback speaker (or are dime sized), let alone any easy AC adapter
Sangean’s first stand-alone digital audio recorder
From the receiver manufacture Sangean comes the consumer DAR-101
digital MP3 “stand alone” desktop recorder. This is not
the first portable audio recorder
from the manufacture. An analog
cassette model QSR-1
had been marketed in Europe for a number of years (was sold
and distributed in the USA by C. Crane). It uses auto-level recording
(arg!). Now long discontinued.
SD card requires extra purchase / No direct computer
The DAR-101 requires a low cost SD (or SDHC) flash memory card to
store its recordings, which is not included. This card is then
moved over to a computer for transfer of the recorder generated
audio files to its hard drive. Host computer will need to have an
on board SD card reader or an external SD to USB adapter will do
the trick. It can use up to 32 GB SDHC cards as well. We used SanDisk
"class 2" 2 GB SD and "class 6" 8 GB cards in testing (both worked
Early promotional advertising for this product indicated:
“To transfer files, all you have to do is plug the recorder
into a computer's USB port.” Well after we scratched our
head for awhile with no answers in the owners manual, we
contacted Sangean USA and they informed us: “The USB jack
cannot be connected to the PC host, it can only play the MP3/WMA
music with USB memory”. So it appears this product feature
was removed before it hit the marketplace? Yes, it has a USB jack
(Male A type), but this is for connection of a flash memory
device and is for file playback only. This arrangement worked
properly and did a good job-hunting out the MP3 files. But why
the direct connection feature was removed is a mystery ?
: Later production no longer features a USB socket at all , as
shown with older sample in the picture below (on the right hand side).

information to get you started, however it misses the boat

card slot and USB jack located on the DAR-101's right side inside
a flip down door.
The USB jack can only be used for PLAYBACK of files on "Flash
Memory" sticks. Had a format issue which locked up the
recorder. We cleared this
up, but without any help from Sangean. WARNING
this is locking type of SD card slot being used, or what I call a
"click in", "click out" type. You can't just
insert without locking "clicking" (pushing)
it into place or clicking (pushing) it in again to remove it . NOTE : More current
longer feature a USB Socket as shown in the picture (on the right)
Construction / Ease of
The DAR-101 is housed in a solid and attractive 2 tone plastic
cabinet. The main operation keys / volume and recording controls have a
cover (coating) around them. A balance control is also
provided around the outer ring of the recording knob. UPDATE : With
the later second test sample, the rubberized coatings are no longer
used which is plus.
Major cabinet Bug-A-Boo with
sample 2 was the volume control was difficult to rotate (almost
binded up completely in one spot). This was because the control was
center (to the cabinet opening) and the case top is more recessed
(thicker) and in rotating the knob was heavily rubbing on the case.
Issue was resolved by removing the "pull-off" knob and using a proper
size X-ACTO® knife and CAREFULLY removed (scraped) enough cabinet
plastic for it
to clear. This is one that drove me CRAZY !
I will NOT be held
responsible for any info that is listed here
ALL DONE AT YOUR OWN RISK !
With test sample 2 the volume control knob
binded up in rotation.
removed the "push on" type knob and used a proper size X-ACTO ® knife
CAREFULLY enlarge the
opening on the left side of the "top silver half" as shown above
(volume control shaft was was off center to the case opening). We did
NOT open the case to fix this. As you can see it took a bit of plastic
removal for the knob to turn totally free. (N9EWO Photo)
With a large 7.1 x 5.2 x 2.0
inch cabinet; it features a built in
3-inch playback speaker and a beefy 1-watt audio amplifier. It
surprisingly sounded above average even if it is just one speaker
(mono) and no tone controls. When recording using the
“Line” input, the speaker output still functions in record (selectable
on later samples). 4
foam type feet on the bottom help to protect the tabletop and
keep it from sliding around in use.
To help access the menus and audio files, there is a jog shuttle
wheel and a enter button. Between this and a pleasing menu layout
make the recorder extremely easy to use. Our first sample arrived with
the “enter” button mounted upside down. Also for some
unknown reason this button did not always take on the first press. Good
news is this was cleared up with the second test sample (firmware
?), so no more sluggish operation.
Power options / AC Adapter Changes / Built in battery charger /
Carrying Case No More
4 alkaline AA batteries provide power for portable use (not
included). If you purchase and install nickel cadmium or nickel
metal hydride rechargeable cells, these can be charged using the
DAR-101’s built in circuit. Charge rate is at 500 mah and an
overheating sensor is provided. There is a small switch nestled
in the battery compartment to select between alkaline and
rechargeable batteries. Charger only operates when the recorder
is off. However , I would recommended to forget the internal charger
a GOOD external one such as the LaCrosse
BC-1000. The internal charger was not tested.
There is a power saving mode that turns off the recorders power
after 1, 3, 5, 10, 30 and 60 minutes (or OFF). As can be figured this
feature is only useful with battery "portable" operation (turn it OFF
with AC Adapter use).
Battery cover is hinged to prevent loss. It was a bit difficult
to get it open however. A battery indicator is provided on the
LCD including a flashing “low” warning.
The included AC adapter with the first test sample was of a
linear-analog type. So this rules
out any radio frequency noise being generated by the use of a
switching type power supply. Recorder itself was found to
be generally radio interference free as well. Just as it is with early
Sangean ATS-909X receiver samples, the rating is 9 VAC at 700ma

this is an AC in and AC out adapter or we have to say it WAS.

removed. This new AC Adapter
(HKP25-0750800dU) could (more like will) make the DAR-101 unsuitable with SW/HF
receivers with possible added RF noise of course (depending on the
Having said that, we checked out
to see how RF noisy the new included switching adapter was in the SW/HF
part of the spectrum. We were
pleasantly surprised. It was pretty clean above say 5 MHz. But below
that is more noisy (especially if you use near field or other nearby
indoor antenna's). However WE despise ALL switching power supplies
around MW/SW/HF receivers, so used a "home built" regulated 7.5 volt DC
linear (transformer) supply using a LM317T regulator IC connected to a linear 12 VDC regulated supply, no added
self-inflicted noise. But for most will be usable with outdoor
antenna's on the host receiver.

The dot matrix LCD size is 2.3 x 1.1 inches. Negative
type monochrome that is backlit with a blue-white color and has
brightness and contrast controls. Also can be tilted for ease of
viewing and when flat has a lock so it has no chance of becoming
loose in transit.
When the jog knob or any button is pressed the brightness is
automatically forced at maximum 9 level. After a few seconds it
then automatically switches to the “brightness” setting
as stored in the menu. At the 1 level setting it shuts off after
the timed period, only coming to life when a button or job wheel
is touched, perfect for portable use to help increase battery
life. With the later production second test sample, the preset
brightness and contrast were not recognized until it was accessed in
menu's, and then it was good again until powered down (a new firmware

Input and Output jacks
On front panel there is a common 1/8-inch stereo headphone jack.
As usual the internal speaker is disconnected when inserted.
Also on the front panel there are two plastic 1/4 inch phone type
microphone jacks. For certain short wave receivers (the Sony ICF-2010
and Kenwood R-1000 to name 2) require a higher mic gain input and
the DAR-101 provides this. A proper Y-cable and or adapters will
be an extra cost option however. There is a microphone gain
setting (hi or low) accessible in the menu. We used
“hi’ in testing and worked properly.
Most communication receivers and scanners will use the rear
mounted plastic “line in” and “line out” jacks
connected to the receiver’s line or headphone/speaker output.
Another Y cable or audio adapter may be needed again if you wish
the recording to appear in both channels.
A plastic 1/8 inch phone jack marked “Remote” allows the on-off
triggering with certain receivers including the Sangean ATS-909,
ATS-909X, CCRadio plus and RadioShack DX-398.

Playback and record
/ Voice actuation / Has Shuffle Play Mode
Play Mode's Available (needs to
be selected every time the DAR-101 is powered on) :
MP3 and WMA files are supported in playback. MP3 bit rate in playback is not
tied down to the 3 record selections.
Playback is a fairly easy feat with the DAR-101 too. Press the
file browser button along with the jog wheel to view the menus
and files with the SD card or USB memory device.
To move (or go back) to the next audio file within that folder
you just hit the fast-forward or rewind buttons. Pressing down
and holding these buttons gives fast-forward or rewind functions.
IMPORTANT NOTE : When stopping playback it does NOT remember exactly
left off (will start at the beginning of that file when LAST TURNED ON,
and stores that even if switched off and power is disconnected). The
way around that of course is to just use "Pause". UPDATE :
"Sometimes" we were able to continue play in the middle of a file after
completely stopping PLAY, but not always.

On board is a "real time clock" that is selectable in 12 or 24-hour
one-event timer for record or playback is also featured.
The VAR function (Voice Activated Recording) is perfect for
scanner receiver use. It has 3 sensitivity levels, with High
being the most sensitive. In our testing “Low” was the
proper for radio scanner use.
Record with 3 bit rates / Peak level indicator
Unlike most other flash based recorder devices, the DAR-101 is
limited to recording in the MP3 format only. There are no
higher quality PCM-WAV record selections to be found.
There are 3 “quality” MP3 bit rates available : 64, 128 and
192 kbps. With a 2 GB SD card (as tested) gives approximate
recording times of 69, 34 and 23 hours respectively.
Peak reading “left and right” record level meters are
featured. These operate in playback as well. There is a total
lack of any scale indicators however. Another answer from Sangean
USA told us that 0 db is the 3 little vertical dots on the far
right side of the scales (see photo above). Unlike analog tape
recorders, one should never go over 0 db at any time.
We found the usefulness of the provided orange LED
“peak” indicator to be limited. If you believe the
information as found in the owners manual, it activates too soon.
Even near the proper 0 db level it flashes on and off at a pretty
good interval. With extensive testing and viewing using a
professional audio program and DAR-101 generated files, as long
as it was not a steady glow and meter levels not past or hitting
0 db excessively, it made for a acceptable recording level (so it can
flash on and off a bit and still be OK).
We did experience ever so slightly lower level indication with the
meters on playback verses when it was recorded.
While in the record mode and when you hit stop, only then is the
actual MP3 file saved to the memory card. If a power interruption
takes place in the middle of a recording being made, that entire
“recorded” file will be lost. “Record Auto Save”
feature allows the DAR-101 to force a file save at 30 minutes, 1, 2 or
hours. If you are making critical recordings or in battery
operation, its recommended to make use this very useful feature.
will leave a gap (and miss a few seconds) while it saves and
starts a new file, which is done automatically. Using this
feature will also help break up files so helps in hunting a
series of long files for locating that important segment.
Overall the recording quality is more than adequate (especially in 128
or 196 kbps / 44100 KHz settings) and very
pleasant. We did find that it struggled slightly in achieving the
proper 0 db level with some communication receivers with weaker "line
output" level . It functioned adequately here as long as it made at
least say 75% deflection (this can be corrected later using
a free computer program such as Audacity).
Improved Firmware on Later Sample
With our later second production sample, the P01 firmware was near
bug free, no more sluggish controls/menu adjustment and just seemed to
more solidly over the early unit. Once in awhile the early sample would
scramble the recorded files (those would be lost forever), no such bug
like this as least as this report was compiled with the later test
So welcomed improvements overall,
except for the the
preset brightness and contrast were not recognized until it was
for a second in the menu's (this was not an issue with the first
earlier sample) .
The Bottom Line
With its attractive low price,
beefy size and above average
internal speaker and amplifier the Sangean DAR-101 makes a very
desirable "stand alone" digital audio recorder. The quality of the
MP3 recordings is more than adequate for most “recording off the
radio” and archiving. Sounds great with music files as well. We did not
test the recorder with telephone use.
One needs to add the cost of a SD card and computer card reader (if
your computer lacks one) with perhaps a few audio cables to the
final price. Even with it's bugs we find the Sangean DAR-101 to
be a real winner for radio "off air" recording warts and all. Be sure
and read the memory card information below.

more "grandeur" model for about $ 300. USD).
An alternative more grandeur home model might be the
SD-20M shown above. Appears to be a nice recorder and is reasonably
(around $ 300. US street). Indeed it too comes with an EXTERNAL
SWITCHING power supply. Good news (again) is that it uses a standard DC
for operation (12 volts at 1 AMP) so one can easily connect a nice "RF
quiet" linear regulated power supply. So it COULD work with the Jameco

a dead quiet power supply.

for better quality. It can also operate on 4 AA batteries. The rack
ears are removable.
There is a optional RC-10 wired remote control that plugs into the

an external amplifier/speakers (or headphones or amplified speakers) to

Format Card Issues. Sangean Does Not Know What "Format" REALLY Means !!
|Here is the Lowdown:
Was getting lockups / dropouts and with DAR-101 generated-made
recordings (files). This intermittent bug happened sooner or later
and sometimes the file got totally corrupted. Another nasty is with
some minor file skipping , more so with the first track on a memory
Now for the Cure : I was doing incorrect type
FAT (file system) for the card being used (done in the host computer) ,
so was getting these errors and corrupted files. To do a format of a
card it has be done in the "host computer" and not in the DAR-101.
Duh....as normal (computer 101 stuff) : A standard "
2 GB " SD card MUST be formatted in
FAT 16 and any SDHC card (over 2 GB) MUST be formatted
in FAT 32.
Any brand new 2 GB SD card "out of the package"
should be pre-formatted
in FAT 16 (will show as FAT) and any size SDHC in FAT 32 . Again this
"standard" basic computer stuff here of course. However, it would not
be a bad idea to format any brand new card just to play it safe, but
again NOT in the DAR-101 .
Here is the part that threw me off base :
Sangean informs me that the DAR-101 does NOT
do an actual card format but just clears the data (recordings). So the
"on board" format function is [somewhat] improperly labeled, and
continues to be with firmware P01.
However I was still having minor skipping issues (with the first file
a card) with the first test sample. UPDATE :
With the second test sample (Firmware P01), this issue has been totally
NOTES : FAT 16 is just labeled as FAT in Windows as one does a
format (using external computer). I would NOT use the "Quick Format"
cards used in testing were a basic " 2 " class and a higher quality "6"
class (both SanDisk). Both worked properly with no issues as
long as the format was proper. We recommend using SD Card formatter
program to format any SD cards (version 5.0 and up).
