Message from the
Development Team
Thank you for choosing the UR242 USB Audio Interface.
The UR242 offers the same sonic quality and functions as
the previously released UR44, but a compact design with
two microphone preamps rather than four makes it closer
in size to the UR22.
Like all UR series models, D-PRE microphone preamp
parts selection and circuit design have been carried out
with meticulous care and attention to detail. The highs are
extended and open, the midrange dense and detailed, and
the lows deliver solid punch. The UR242 inherits the highly
regarded sonic character of the Yamaha n8 and n12 Digital
Mixing Studios, the Steinberg MR816 series audio
interfaces, and of course the UR series.
The UR242 combo inputs feature pads that allow a wide
range of sources, from high sensitivity microphones to line
level devices, to be connected while fully retaining even the
subtlest musical nuances. The level controls have been
designed with extra care to ensure minimum noise when
recording.
No compromises have been made in the outputs that drive
the monitor speakers either. Every effort has been made to
ensure that spatial depth is accurately reproduced so that
our users can accurately hear width, depth, and the tiniest
variations in loudness in exquisite detail.
Built-in DSP delivers the same refined sonic quality and
creative potential as the high-end models, with features like
True Integrated Monitoring for ultra-low-latency recording,
REV-X reverb effects, a Channel Strip that is packed with
professional compression and equalization know-how, and
Guitar Amp Classics featuring modeled guitar amplifiers
from the vintage era through to heavier modern sounds.
Expandability is enhanced by iOS support that provides
simple plug-and-play operation with the Apple iPad. With
an iPad and an iOS compatible audio application such as
Steinberg Cubasis it is easy to record and create with
impressive quality just about anywhere. There’s also a
loopback function that can be handy for video delivery in
today’s fast-paced Internet environment.
High-quality recording that anyone can enjoy is here. We
sincerely hope that the UR242 will contribute to the
creative efforts of beginners as well as professionals.

HINT
What is Loopback?
Loopback is a convenient function for broadcasting
over the Internet. It mixes the input audio signals
(such as microphone and guitar) with the audio
signals playing back in the software in the computer
into two channels in the UR242, and sends them
back to the computer.
Loopback Function Precautions
If the Loopback function is on while you are
monitoring input signals from the UR242 via DAW
software, it will cause loud noise. This is because an
infinite loop of the audio signal is generated
between the UR242 and the DAW software. When
using the loopback function, turn off the monitor
functions on your DAW software.

Sweet Spot Morphing Channel Strip
The Sweet Spot Morphing Channel Strip (“Channel Strip”
for short) is a multi-effect that combines compression and
EQ. Advanced sound engineering know-how is condensed
into a number of convenient presets that can be simply and
instantly recalled, for professional results.
Four channel strips are provided, and each can be
assigned to the monitor sound only, or to both the monitor
and recorded sound.
The Channel Strip equipped with the device and the
Channel Strip of the VST Plug-in version have the same
parameters. When using the Channel Strip on Cubase
series programs, you can share the settings between the
built-in Channel Strip and the Channel Strip of the VST
Plug-in version as a preset file. When using the built-in
Channel Strip on Cubase series programs, turn on the
[Direct Monitoring] setting in the program. Also, when
assigning the Channel Strip of the VST Plug-in version to
the effect slot on Cubase series programs, select it from
the [Dynamics] category (in the case of the default
settings). Note that you cannot use the built-in Channel
Strip when the sample rate is set to 176.4 kHz or 192 kHz.

REV-X
REV-X is a digital reverb platform developed by Yamaha for
pro audio applications.
One REV-X effect is included in this unit. Input signals can
be sent to the REV-X effect, and the REV-X effect is
applied only to the monitor outputs. Three types of REV-X
are available: Hall, Room, and Plate.
The hardware REV-X equipped with the device and REV-X
of the VST Plug-in version have essentially the same
parameters. However, the [OUTPUT] and [MIX]
parameters are only available in the VST Plug-in version.
When using REV-X on Cubase series programs, you can
share the settings between the built-in REV-X and REV-X
of the VST Plug-in version as a preset file. When using the
built-in REV-X on Cubase series programs, turn on the
[Direct Monitoring] setting in the program. Also, when
assigning REV-X of the VST Plug-in version to the effect
slot on Cubase series programs, select it from the [Reverb]
category (in the case of the default settings).
The built-in REV-X is equipped with an “FX Bus” which is
used for sending the signal from DAW software to REV-X.
For example, to send the recorded audio data to REV-X,
you can check the sound with REV-X, which is used for
monitoring during the recording.

Guitar Amp Classics
Guitar Amp Classics are guitar amp simulations that make
extensive use of advanced Yamaha modeling technology.
Four amp types with different sonic characteristics are
provided.
The Guitar Amp Classics equipped with the device and the
Guitar Amp Classics of the VST Plug-in version have the
same parameters. When using the Guitar Amp Classics on
Cubase series programs, you can share the settings
between the built-in Guitar Amp Classics and the Guitar
Amp Classics of the VST Plug-in version as a preset file.
When using the built-in Guitar Amp Classics on Cubase
series programs, turn on the [Direct Monitoring] setting in
the program. Also, when assigning the Guitar Amp
Classics of the VST Plug-in version to the effect slot on
Cubase series programs, select it from the [Distortion]
category (in the case of the default settings).
Note that Guitar Amp Classics cannot be used when the
sample rate is set to 176.4 kHz or 192 kHz.
