The Tascam MiNiSTUDIO Creator US-42B is a computer audio interface that has been developed to enable anyone to broadcast their programs to the world with ease. By using a dedicated device with high-quality audio circuits for mic and instrument input you lay the foundation for impressive sound in high quality. Moreover, the MiNiSTUDIO Creator offers several techniques that can make programs more interesting in order to grow your audience. Professional broadcasters, for example, call pre-recorded clapping, cheering and other sounds with a press of a button. With the Sound Pads on the MiNiSTUDIO Creator you too can trigger such sounds simply by pressing buttons. There is also a ducking function that lowers the volume of background music during announcements. And you can use voice effects and reverb to improve the atmosphere and raise the level of excitement of a program.

Tascam US-42B user interface description

Did we say audio quality? Providing your audience with sound that is easy to follow is also a way to make them feel more welcome. The MiNiSTUDIO Creator has excellent audio circuits inherited from music creation devices, so you can capture clear sound just by connecting a mic or other sound source.

Since you will operate this device while broadcasting, ease-of-use is very important. The user interface has as few controls as possible so that it can be used intuitively even by people who are not knowledgeable about audio equipment. In addition, the dedicated software used for selecting sound effects and triggered sounds, has an EASY page that anyone can use and an EXPERT page for advanced users with all the details you can imagine.

Use a Tascam MiNiSTUDIO Creator to make your own unique broadcast programs, or create podcasts that not only convince in terms of content, but also in terms of sound.

User interface designed for personal broadcasting that anyone can easily operate

Among the features of the MiNiSTUDIO series, the user interface is the biggest difference from audio interfaces design for music creation. We started from scratch and designed these units especially for personal broadcasting, carefully choosing the controls so that even people who are not familiar with audio equipment can use them without trouble.

Broadcasting music and talk with the Tascam US-42B

Compatible with both headset mic and 4-pole earphones with mic

In addition to supporting professional external mic, a MiNiSTUDIO is also compatible with computer headset mics and 4-pole earphones with mic designed for smartphones. You can use equipment that you already have for personal broadcasting with these units. When using a 4-pole earphones with mic, connect it to the dedicated earphones mini-jack.

Input sounds can be heard at all times

The input monitoring method allows you to listen to the audio using headphones before it is sent to the computer. The input sound is always sent to the headphones output, so no special setting is needed for this.

“On Air” button to start sending

Press the ON button to start sending the sound that you are hearing in the headphones to the computer. The button will light when sound is being sent.

Loopback function enables streaming of the computer output sound

Using the loopback function that mixes in the playback sound from the computer (WDM) and sends it back to the computer, you can play program background music using music playback software (iTunes or Windows Media Player) that is already installed on the computer. Since this loopback function is always on, no special setting is necessary. Moreover, the stereo AUX input mini-jack enables the connection of an iPod or other portable music player to use for playback. You can also connect a synthesizer or other stereo instrument to the AUX input jack using a conversion cable (sold separately).

Lightweight design and strap attachments enable use for mobile broadcasting

The lightweight design of the MiNiSTUDIO units means you do not have to hesitate to take one with you. You can attach a commercially-available camera strap and use the unit hanging from your neck. The mic input jacks use locking mechanisms to avoid disconnection during movement.

Multiple audio sound effect functions that are not found in ordinary audio interfaces and sound cards are built-in. With the dedicated software, in addition to making detailed settings, you can also easily operate the unit with the controls assigned to the unit. You can apply effects in real time during a program.

Tascam MiNiSTUDIO US-42B

Play jingles or sound effects just by pressing the trigger pads

The unit has three sound trigger pads. You can press such a button to play the sound effect or other audio file assigned to it. You can use the dedicated computer software to assign the desired WAV/MP3 audio files to the trigger pads by dragging and dropping them.

Note: The trigger pads cannot be used when connected to an iOS device.

Different effects can be easily selected on the Tascam MiNiSTUDIO US-42B

Voice effects with presets for speech and vocals

You can use the unit’s internal voice effects to change mic input sounds by pressing the EFFECT button. Choose from five types of voice effects according to the purpose for your program.

Tascam MiNiSTUDIO Series

Reverb effect can be adjusted with a dedicated knob

Reverb effects that add spatial sound are useful when broadcasting performances with singing and guitars, for example. Turn the knob to add reverb to the input signals. You can change the reverb type and settings using the dedicated software.

The ducking function on the Tascam MiNiSTUDIO Creator makes announcements and voice-overs a snap

Ducking turns the music down when you speak

Ducking is a technique commonly used by radio moderators or DJs. It turns down the volume of a signal as soon as it detects another signal, for example from a microphone. This means you can make announcements over the background music and your words are clearly legible without touching any knob. The music turns down automatically and raises its level again as soon as you stop speaking. You can also use this function to overlay songs or foreign language speakers with translations.

EASY and EXPERT settings

The dedicated software for changing settings has an EASY page that is simple to use and an EXPERT page that allows you to make advanced settings. On the EASY page, you can change the sound simply by selecting a preset, so you will be able to enjoy using effects easily even if you do not have audio equipment knowledge.

Tascam MiNiSTUDIO Series

Tascam MiNiSTUDIO SeriesWe freely applied the audio circuit development techniques that we have gained in making professional broadcasting and music production equipment. We have realized high audio quality that is in a different class from that provided by computer input and output jacks and sound cards. Simply by using the MiNiSTUDIO series, you can enjoy personal broadcasting and audio production with high quality sound without needing to do anything else such as making particular settings.

Tascam MiNiSTUDIO SeriesLow-noise mic inputs that support condenser mics

We applied our expertise gained from the development of professional audio and music creation equipment to the audio circuits, starting with the mic inputs. With them, you can achieve audio that is clearer and has lower noise than is possible using a computer audio input or sound card.

Preamps with extravagant discrete construction

Tascam MiNiSTUDIO SeriesThe MiNiSTUDIO Creator, which also supports audio creation, uses input circuits of even higher quality. Mic sound quality is dependent on the mic preamplifier. The HDDA (High Definition Discrete Architecture) mic preamps use discrete construction that requires a higher number of components. This distances them from other preamps. We selected all the parts through listening evaluations to tune the sound quality.

Equalizer and compressor preset for talk programs

The built-in equalizer and compressor, which are functions to adjust the sound, are set for use with a talk show when the unit is shipped new from the factory, so you will be able to achieve clear sound without changing any settings. You can change the sound to a type you like simply by selecting a preset using the dedicated software.

Two input jacks

The MiNiSTUDIO Creator has two mic input jacks that can be used for various applications including performances with vocals and instrument or guest interviews. Both support the direct input of condenser and dynamic mics as well as guitars.

Switch between the EASY tab for basic settings and the EXPERT tab for advanced settings in the dedicated software. On the EXPERT page, in addition to making fine adjustments to equalizer, compressor and other effect settings, you can also change the signal routing.

Tascam MiNiSTUDIO Series4-band equalizer and serious compressor

The full-featured 4-band equalizer has High and Low shelf bands, and High Mid and Low Mid bands with peaks. The Low band can be changed to a low-cut filter (LCF), which is convenient for cutting low frequencies entering a microphone.

Adjustable voice effect parameters

You can adjust the parameters of the voice effects for the mic inputs or switch the effect off independently. For example, to use it only on MIC 1, turn the effect off for MIC 2.

Detailed settings can be made for the sound trigger pads

You can configure the trigger pads according to your needs. Settings made on the EXPERT page are retained even after switching to the EASY page.

  • FADE IN: Sets the fade-in time when played.
  • FADE OUT: Sets the fade-out time when played.
  • LEVEL: Sets the playback volume.
  • START TIME: Sets where playback starts in the file. Use this when silence occurs at the beginning of a file.
  • REPEAT: Switches repeat playback on/off.
  • UNLATCH: Set to ON to make playback continue only while the sound pad is being pressed. Set to OFF to make playback continue until the pad is pressed again.
  • VELOCITY: When set to ON, the sound pad is sensitive to how hard it is played and the volume of the playback sound is automatically adjusted.
Tascam MiNiSTUDIO Series

Change the signal routing according to use conditions

MiNiSTUDIO units support both ASIO and WDM drivers. By enabling the ASIO driver which is switched off by default, you can apply additional effects using ASIO-capable software on your computer.

You can also set the audio sent to the computer to Mono or Stereo. By default, it is set to Mono. When using streaming software that supports stereo, set it to Stereo to enable high-quality stereo broadcasting.

Put a delay on your audio to make it synchronuous with your video image – Tascam MiNiSTUDIO Creator

USB output delay makes your sound again synchronous with your image

One big struggle that occurs during live streams is the delay between the video image and the sound. The reason for this is that video processing requires more computer power than sound processing, which means that the sound is ready sooner, so to speak, and is therefore ahead of the picture.

With a MiNiSTUDIO Creator you can compensate this offset by delaying the sound by the same amount. Just enter a number in units of milliseconds (one-thousandth of a second) on the screen and check the result in realtime. You can choose any value between 0 and 2000 ms (2 seconds) for correction.

The MiNiSTUDIO models are designed especially for personal broadcasting, but the MiNiSTUDIO Creator advanced model also supports creative activities. Using the switch on the front of the unit to change the mode automatically changes internal signal routing:

  • BROADCAST mode is optimal for personal broadcasting. The loopback function is on and the MIC 1 / MIC 2 inputs are automatically set to mono in this mode. (Be careful with the speaker volume because the signal will loop.)
  • CREATOR mode is best when using DAW software to create music or video. In this mode, the loopback function is off and the MIC 1 / MIC 2 inputs are sent to the computer separately.
