Recording Menu
This menu lets you determine the recording format for subsequent audio recordings; changing these settings will have no effect on any of the files
currently stored in memory. This menu will show a list of parameters with their values after them. To change the values, first select the parameter
by pressing up or down on the [NAV] wheel then press in on the [NAV] wheel to select the parameter. Once selected, pressing up or down on the
[NAV] wheel will change the value of the parameter. Once the desired value is shown, press in on the [NAV] wheel to confirm your selection and
return to the previous menu. The options in this menu are as follows:
1. Input Source: This is where you select which input of the MicroTrack 24/96 to use for recording.
1/8” . . . . . . . . . . . . . .
Chooses the 1/8” mic input as the recording source.
TRS–1/4 inch
. . . . . . . . Chooses the 1/4” TRS jacks as the recording source. You will also need to use the [L/M/H] switch to set the
operating mode for these inputs.
S/PDIF . . . . . . . . . . . . Selects the S/PDIF digital input as the recording source. When S/PDIF is selected, the [LEVELS] buttons will
have no effect.
2. Input Monitoring: Input Monitoring is the ability to listen to the incoming audio signals before and/or while recording is in progress. This
can be extremely helpful when recording digital sources since there’s often no other way to hear the digital signal you’re trying to record.
It will also help you hear if your recording is distorting. When Input Monitoring is active, the currently selected input will be heard at the
headphone and RCA outputs. Playback signals will override input monitoring.
3. 27dB TRS Input Boost: When this option is set to on, incoming signals will be boosted 27dB before being recorded. This is helpful when
recording quiet sound sources or when using mics with low output levels.
4. Encoder:
WAV . . . . . . . . . . . . . . Chooses WAV as the recording format. This format is uncompressed and will yield the highest quality
recordings. Be aware that the files created in this format can be quite large.
MP3 . . . . . . . . . . . . . . Selects MP3 as the recording format. This format compresses the audio data to yield smaller file sizes.
Unlike WAV format, MP3 files are not identical representations of the original signal. They have had portions
of the audio signal removed in an effort to keep file sizes to a minimum.
5. Sample Rate: The options available in this menu will depend on the Encoder selected above. Keep in mind that file sizes will increase as
the sample rate is increased.
44.1 / 48 / 88.2 / 96
. . . . These will be the available sample rates when WAV is selected as the encoder. 44.1kHz is the rate for CDs.
96kHz will yield the highest frequency response, but also the largest file size.
44.1 / 48 . . . . . . . . . . . These will be the available sample rates when MP3 has been selected as the Encoder. 44.1kHz is the rate
used for CDs.
6. Bit Depth: Like Sample Rate, the options shown in this menu will depend on the Encoder selected above. Keep in mind that file sizes will
increase as this setting is increased.
16 / 24 . . . . . . . . . . . . When WAV is selected as the encoder, this menu will allow you to set the bit-depth of your recording. 16-bit
is the CD standard. 24-bit will yield increased dynamic range and increased file size.
96 / 128 / 160 / 192 /
224 / 320 . . . . . . . . . . . When MP3 is selected as the encoder, this value will determine the bit-rate of the file. 320kbps will yield the
best sounding file, but it will also be the largest.
7. Channels:
Stereo . . . . . . . . . . . . . The Stereo option will cause the MicroTrack 24/96 to record both the left and right inputs into discrete
channels. This is the default setting for the MicroTrack 24/96.
Mono
. . . . . . . . . . . . .The Mono option will cause the MicroTrack 24/96 to only record one channel of audio instead of two.
8. Record Time Available: This is not an adjustable parameter as it merely shows the space available on the media in the MicroTrack 24/96.
This information is provided here to help you make a choice of which recording parameters to use. If you see that you’re getting low on
memory space, you can choose to use MP3 encoding instead of WAV to yield smaller recordings.
