PRODUCT MANUAL PRODUCT MANUAL 17 16 DIRECT TO USB RECORDING DIRECT TO USB RECORDING
Choosing an appropriate number of tracks for your particular recording session has the following
advantages:
• The amount of available space on the attached USB drive is not wasted on “empty” tracks
that are not actually being fed an audio signal
• When attaching the USB drive to a computer and copying the files over, the drive will not
contain “extra” tracks that are empty and are not relevant to the take
○ In 2-track mode, audio inputs 1-2 are active
○ In 4-track mode, audio inputs 1-4 are active
○ In 8-track mode, audio inputs 1-8 are active
○ In 16-track mode, all 16 audio inputs are active
8.9.2. Sample rate & sample width (bit-depth)
This screen allows you to select both the sample rate, as well as the sample width of for the LR-16.
The default recording settings are:
• 44.1kHz / 16 bit (automatically selected if a smaller form factor USB “thumb drive” is
inserted)
• 44.1kHz / 24 bit (automatically inserted if a USB hard drive is inserted)
Use the Up / Down and Select buttons to make a selection, if you wish to select a sample rate/
bit-depth other than the ones automatically selected by the LR-16.
!
Note: The LR-16 does not distinguish between the above two types of drives based on the read/
write speed that it discovers on the drive, during the drive test procedure. Instead, the LR-16
reads the “device ID’ that all external USB drives contain, where the type of drive is reported to
the recorder.
!
Note: When selecting 96kHz, the LR-16 will be restricted to recording 2-channels only. When
selecting the number of tracks to be used in the recorder configuration screen, all choices except
2 tracks will be unavailable for selection.
Newer generations of thumb drives are now available that offer the read/write speeds of a
conventional USB external “spinning platter” hard drive, and will report themselves to the recorder
as a hard drive. Check the Cymatic Audio website for the latest details on recommended drives.
8.9.3. Pad settings
The rear-panel analog inputs of the LR-16 contain a set of 16 individual level “pads” that allow you
to adjust the input sensitivity of each input.
Since the LR-16 is most often interfaces with a live sound mixing console, there may be times
when the channel gain has been optimized for the mixing console, but is outputting too high a
signal level, out of the mixer’s insert sends or direct outputs, to the LR-16 recorder. You will know
if this is occurring if you see the “peak” segments illuminating on the LR-16’s input meters.
In these situations, turning the LR-16’s input pads to the “on” setting will allow you to lower the
input level, by 10dB, on a channel by channel basis, and thus avoid overloading the relevant
inputs.
This approach is preferable to lowering the channel gain on the mixing console itself, which would
affect the gain staging for the audience mix that has been carefully set up by the Front of House
engineer.
Use the Up / Down buttons to select a channel to adjust the input pad for, and then press the
Select button to toggle the pad on/off.
Additionally, when initially entering the Pad Settings menu option, all channels can be toggled
between pad on/off.
8.9.4. Monitor settings
The LR-16 contains an internal digital mixer that mixes down the 16 individual channels to a
single master stereo signal, allowing you to easily monitor a stereo mix of the tracks that are being
recorded.
This function is very useful because it allows you to monitor a mix of all of the tracks being
recorded, as a group or checking individual channels, without any additional equipment beyond
a pair of headphones connected to the front panel headphone output.
The Monitor Settings screen is where you can adjust various aspects of the internal digital mixer
on a per channel basis. Including:
• Channel level
• Channel left-right panning
