1. Option Card Slot
The uTrack24 can be fitted with an optional 24-input, 24-output option card that provides an alternate audio I/O path
from the onboard analog I/O. The first currently available card is a MADI I/O card; more flavors of digital I/O will be
available in the future.
This option brings a powerful level of flexibility to the uTrack24, allowing you to:
Expand the unit with 24 channels of digital I/O, and then use that I/O with your own A/D and D/A converters
of choice.
Add a digital I/O format to the uTrack24 that allows 24x24 channels of networked audio, allowing the unit to
conveniently integrate into large setups with a single cable.
Allows the use of external clock from the Digital I/O card to be used in the uTrack24.
2. Analog Outputs 1-24
These 24 outputs carry 24 channels of audio either from:
A multi-track audio project from a USB drive connected to the front panel USB port
A multitrack DAW session running on a computer connected to the rear panel USB port
3. Analog Inputs 1-24
Connect the 24 separate audio signals that you wish to record to these inputs; the 24 separate audio signals can then
be recorded to either:
A USB drive connected to the front panel USB port
DAW software running on a computer connected to the rear panel USB port
Both the analog inputs and outputs operate at balanced line level, +20dB, and are configured as three separate, 8-
channel, 25-pin D-subminiature connectors. The D-sub connectors are wired to the “Tascam Standard” as shown
below.

REAR PANEL 11
User Manual
uTrack24
May 2016
4. Main Outputs
The balanced stereo main outputs on ¼” tip-ring-sleeve (TRS) jacks can be sourced from either:
The stereo output of the onboard 24-channel monitor mixer. In this scenario, the main outputs allow you to
monitor a stereo mix of the 24 input or output channels.
Output channels 1-2 of your favorite DAW software. In this scenario, the main outputs allow you to monitor a
stereo mix of your DAW session, when using the uTrack24 as a computer audio interface in a recording
studio.
5. Word Clock Input
The uTrack24 can be “slaved” to an external word clock signal by connecting it to the BNC word clock input. This
allows the uTrack24 to be integrated into a larger complement of digital audio equipment, where the clock signals of
all connected equipment need to be synchronized.
Adjust the uTrack24’s “Word Clock” menu to configure it to slave to an incoming external clock, as opposed to
running on its own internal clock. The settings bar at the top of the LCD screen will indicate whether the uTrack24 is
using an internal or external clock signal.
6. Word Clock Output
This connector outputs a standard digital word clock signal, running at the sample rate that the uTrack24 is currently
set to. The word clock output is useful when you want to use the uTrack24 as a “clock master” and wish to slave
other digital equipment to its internal clock signal. It could also be used to loop the incoming word clock signal to
another device.
7. Synchronization Connectors
These synchronization connectors are non-functional with the present firmware. Use the Ethernet-based SYNC
feature for syncing up to 4 uTrack24 units.
8. MIDI Output Connector
The MIDI output connector outputs MIDI data from a SMF (Standard MIDI File) that is exported with a song using
uTool..
This allows the uTrack24 to output MIDI data to a software synthesizer, MIDI controlled lighting system, effects
switching system, etc., synchronized and in time with audio data that is played out of the uTrack24’s audio outputs.
9. USB Connector
The rear panel USB connector can be connected to the USB port of a Windows or OS X computer, or an iPad
camera connection accessory. The uTrack24 acts as a 24-input, 24-output computer audio interface in this case.
The 24 separate outputs allow for great flexibility in routing outputs from a DAW session, such as sending many
separate headphone mixes to an external headphone amplifier, or sending 24 separate channels of audio to an
external analog mixer, for “mixing out of the box”.

REAR PANEL 12
User Manual
uTrack24
May 2016
10. Network Connector
This RJ45 connector allows connection of the uTrack24 to a standard Ethernet network. The network connection can
be used for two different functions:
Updating the uTrack24 firmware
Controlling the uTrack24 from the uRemote software
Synchronizing up to 4 uTrack24 units and control them through uRemote as one large multi-track device
11. Power Connector
Connect the included external power supply to this connector. Do not connect any other power supply except the one
that was supplied with your uTrack24.
Note: that the uTrack24 does not contain an “on/off” power switch; this is by design, as it reduces the possibility of
accidentally shutting down the unit during a critical recording from pressing a power switch.
Note: your uTrack24 is always powered on when connected to the power supply.

USAGE: MIXER FOR LIVE CONCERT RECORDING 13
User Manual
uTrack24
May 2016
9. USAGE: MIXER FOR LIVE CONCERT RECORDING
The uTrack24 is the perfect tool for capturing up to 24 individual tracks of a live concert, which can then be imported
into your DAW software of choice. The physical connections work as follows:
Connect 24 balanced, direct outs of an analog mixer to the analog inputs of the uTrack24
Connect a pair of headphones to the uTrack24’s front panel phones jack, or a set of monitors to the rear panel
main output; you can monitor and adjust an onboard stereo mix of the 24-track recording.
At the same time, the uTrack24 allows you to play back 24 channels of multi-track audio back into the live sound
console, perfect for performing a “virtual sound check” using recordings of previous performances, or for
expanding live performers with individual pre-recorded tracks.
Connect the analog outputs of the uTrack24 to the line inputs of the mixer. The FOH operator can switch to the
mixer channel’s line inputs to monitor the uTrack24’s 24 channels of playback.

USAGE: RECORDING SPLIT/OUTBOARD MIC PREAMPS 14
User Manual
uTrack24
May 2016
10. USAGE: RECORDING SPLIT/OUTBOARD MIC PREAMPS
In some instances, you may wish to use the uTrack24 in a higher end remote recording setup, with a dedicated
recording split of the stage snake (as opposed to the mixer’s direct outputs).
In this case, the connections would work as follows:
The stage microphone signals are connected to a microphone splitter containing a dedicated split of recorder
outputs
Connect the recorder outputs (mic level signals) to the inputs of the microphone preamplifiers
Connect the line level outputs of the microphone preamps to the analog inputs of the uTrack24
Connect a pair of headphones to the front panel phones jack, to monitor a stereo mix of the uTrack24’s multi-
track recording
If you are working in an acoustically separated space from the musicians themselves, you can also connect a
pair of powered monitors to the uTrack24’s rear panel main outputs. This will allow you to monitor the onboard
stereo mix on a pair of powered monitor speakers and also adjust the monitoring volume using the front panel
volume control.

11. GETTING STARTED WITH RECORDING AND PLAYBACK
11.1. Preparing the attached USB drive for recording
The uTrack24 records 24 separate tracks of audio, directly to a USB drive. The attached USB drive must be
formatted in the “Fat32” format.
Note: In order to ensure that the USB drive is optimally formatted for audio recording, it highly advised that you format
the attached USB drive using the uTrack24’s “Format USB Drive” menu function. uTrack24 uses a cluster size which
is optimized for reading and writing data.
Note: All existing data and partitions on the drive will be lost when formatting.
To do so, press MENU, scroll to “UTILITIES”, then press the encoder to select “Format USB Drive”. After verifying
you want to do so, you will see the following screens:
11.2. USB Hard Drives vs. USB Flash Drives
When recording audio with the uTrack24 and a connected USB drive, it is important to understand the difference
between the two key types of USB drives available in the marketplace
1. USB Hard Drive
A USB hard drive is a traditional “moving parts” hard drive that records its data on spinning platters. This is the
recommended type of USB drive to use with the uTrack24, as its data read/ write speeds are the most reliable and
consistent
2. USB Flash Drive
A USB Flash drive is a USB drive that uses flash memory and contains no moving parts. Thumb drives and Solid
State Drives(SSD) are flash drives.
These drives offer very fast data read/write speeds, but they are subject to occasional pauses in data writing which is
not practical for a device like the uTrack24 that needs to constantly write a data stream to the drive in order to avoid
dropouts.
To avoid recordings without dropouts, follows these steps:
Use a USB hard drive
Format the attached drive using the uTrack24 format utility only. The uTrack24 uses a cluster size which is
optimum for recording.
Perform a test recording using your planned USB hard drive, making sure the test recording is as long, or
longer than the event you plan to record. Check that you do not have any dropouts in the recordings.

11.3. Recording
The uTrack24 uses the following default recording settings:
24 tracks
24-bit
48 kHz
To change any of the above settings, use the Recording menu from the Settings menu.
See section “Recording Menu” for more details.
1. Starting a Recording
To begin a recording, simply press the front panel RECORD button. The display will switch to the RECORD screen.
For the first two seconds, the number of active recording channels is displayed on the screen and then it switches to
showing the recording name and time.
2. Adding Markers
During recording the uTrack24 allows you to add markers to the take. Markers are locational references that help you
remember different spots in the recording (song 1, song 2, verse, chorus, etc.). Press the PLAY or SKIP buttons
during recording to add a new marker. Up to 99 markers are allowed per take.
If supported by your DAW, these markers will be visible in the DAW session after you have imported your files. The
markers can also be used to split your recordings at the marker points when using the uTool to copy the recording
from your USB device to your computer.
3. Gapless Recording
While recording press the RECORD button to create a new take without losing a single audio sample. The recording
parameters are the same as for the previous take. Tracks created in this way will be played back gaplessly.
11.4. Playback
11.4.1. File playback modes
When playing back audio, the uTrack24 offers different playback “modes”. The uTrack24 switches to a given
playback mode depending on what type of audio folder is loaded for playback. The different modes are:
1. Multitrack Mode
When a USB drive is attached to the uTrack24, the audio content in the folder labeled “MultiTrack” is automatically
loaded on the screen. uTool places all multitrack songs inside the “MultiTrack” folder. All recordings done on the
uTrack24 are also saved in the “MultiTrack” folder.
2. Stereo Mode (not available in SYNC mode)
Stereo songs can be placed in “Music” folder or anywhere outside the “MultiTrack” folder. The stereo songs may be
used for walk-in music, break music, walk-out music, etc. The uTrack24 switches to stereo mode any time you select
a stereo song from the browser.
3. Playlist Mode
A set of songs can be placed in a specific order inside a playlist file. Each song can be started with different delay
options. A playlist can be created using uTool application. When a playlist is loaded, the display shows the playlist
name along with the active song and the next song in the list.

To cancel the playback loop press the BACK button
Note: Pressing the skip backward button while in a loop will cause the playback to start from the loop mark-in point.
When markers are present, the skip buttons jump to the nearest available marker.
4. Autoplay a Playlist on Startup
The uTrack24 has the ability to automatically playback a playlist upon powering up.
To set a playlist for automatic playback, follow these steps:
Within uTool, enable the “Auto” option for the playlist that should be played automatically on startup
In the uTrack24 Playback settings, set the “Autoplay on boot” option to ON
When exported, the playlist selected as “Auto” will be named as ‘autoplay.play’ and placed in the #PLAYLIST folder.
There can only be one autoplay playlist per drive. This playlist will automatically be loaded and begin playing back,
whenever the uTrack24 is powered up. If the USB drive has an autoplay playlist in both the “Music” folder (stereo)
and the “MultiTrack” folder, the multitrack playlist is the one that is loaded on startup.
Note: In SYNC mode, make sure all slaves are powered up BEFORE the master device is switched on. This
procedure will ensure synchronous playback upon startup.
5. Midi File Playback
The uTrack24 contains a standard 5-pin MIDI output connector on its rear panel. This connector can be used to play
back MIDI data from a Standard MIDI File(SMF).
The midi file can be placed in uTrack24 multitrack audio project using uTool software. For complete details on the
operation, please refer to the latest version of the uTool user’s manual. The playback of the midi file is synchronized
with the audio files that are played back from the same project.
An offset for the midi file playback can be applied from the playback settings menu.
Note: When stopping or pausing a song, all notes off command is sent out on the midi port
Note: Long pressing the STOP button sends out a midi panic reset. In panic reset, all notes off commands for each
channel along with note off for each instrument of each channel is sent out.

12. FILE FORMATS
The uTrack24 is specifically designed for continuous capturing of audio over longer periods of time. When recording,
the uTrack24 stores data from multiple input channels into a single multichannel wave file. When the file size of this
multichannel wave file reaches 2GB, recording continues into a new multichannel wave file (chunk) without losing a
sample of the recording. A recording “take” continues until 12 hours before starting a new take automatically. This
allows you to record without any time limit.
uTool allows easy conversion between mono wave files and multichannel wave file songs. Recordings can be
imported into the computer and songs and playlists can be exported to a drive using uTool.
A typical recording workflow looks as shown below:
The workflow for playback looks as shown below:
When playing back a take, the uTrack24 performs seamless transitions from the end of one “chunk” of multi-channel
audio to the beginning of the next one. Multiple chunks inside a take are played back as if they were one long take.
