PRODUCT MANUAL PRODUCT MANUAL 35 34 UPDATING THE FIRMWARE ON YOUR LR-16 SPECIFICATIONS
13. UPDATING THE FIRMWARE ON YOUR LR-16
Please check the Cymatic Audio website ( www.cymaticaudio.com ) for any available firmware
updates.
The LR-16’s currently installed firmware version is shown briefly on the start screen when the unit
is powering up and can also be found in the PC Mixer Panels ‘About’ tab.
If you find that your firmware version number is lower than the latest firmware released on
the website, please download and install the newer firmware, following the instructions that
accompany the firmware download file.
14. TROUBLESHOOTING
Always make sure that you have downloaded and installed the latest drivers and firmware for
your Live Recorder LR-16. The latest firmware and driver downloads are available at http://www.
cymaticaudio.com
14.1. Direct-to-USB recording mode / Player mode
Problem Possible Solutions
When I listen back to my recording, I hear
noise or buzzing on some of the tracks
Check the audio connections feeding the LR-16
recorder for any loose connections.
My recording has audio drop-outs, even
though the USB storage device performance
test was successfully passed
Format the USB storage device using the LR-16’s
format function. This will optimize the file system to
work as effectively as possible.
In advance of your live recording, perform your own
manual testing process, where you record silence
for as long a time as the recorder will allow, and then
check if any dropouts are reported at the end of the
process.
My external USB2.0 hard disk is not
recognized by the Live Recorder when
plugged in, even though I can hear that the
disk is running.
The hard disk may be asking for more USB bus power
than is allowed by the USB standard for bus powered
devices. Try using the hard disk with its external power
supply, if one is available.
The meters on the LR-16 are showing peak
overloads too often, and I am hearing digital
overload distortion on the tracks.
Adjust the pad settings on the problem channels,
turning on the 10dB pad for the channels that are
overloading.
If feeding the LR-16 from the inserts or direct outputs
of a console, reduce the mic input gain level on the
console’s input channel.
I am not able to make adjustments to the
internal monitor mixer when recording. I
would like to mute or solo some channels
while the recording is occurring.
This is expected behavior. The settings for the internal
monitor mixer can only be adjusted when a recording is
being played back, but not while recording.
14.2. 16 Channel USB audio interface mode
Problem Possible Solutions
On my Windows PC, the LR-16 is not
recognized by the PC, even though I the
device drivers have been installed and the
device is plugged in using the supplied USB
cable.
Make sure that there is no USB storage device
connected to the front panel USB storage connector
of the LR-16. Doing so will automatically put the LR-16
into “recorder mode” and it will not be usable as a
computer audio interface at the same time.
When I connect the rear-panel stereo line
output to my powered speakers, the signal
is too loud and I have no way to adjust the
listening volume.
The stereo line output of the LR-16 does not have
a volume control of its own. To use it with a set of
powered speakers, you can:
1-Connect the stereo output to a pair of powered
speakers that have their own onboard volume control
2-Connect the output of the LR-16 to the line inputs of a
small desktop audio mixer or standalone volume control
unit, and then connect the outputs of those to your
powered monitors.
I cannot find the Macintosh OS X version of
the monitor mixer control panel
Currently, no OS X version of the monitor mixer control
panel is available.
