Optimal interface for home recording with 4 mic/line inputs, USB bus power, and 2 headphone outputs
The US-4x4HR is equipped with 4 mic/line inputs with guitar input support on IN 1-2 plus 2 headphone outputs that can be put to use in various music/multi-media production environments such as vocal/guitar simultaneous recordings and multitrack recordings. The unit is also equipped with a USB-C port to be easily powered by USB bus power.
Natural, crisp & clear sound quality thanks to the implemented Ultra HDDA Mic Preamp with 192 kHz support
High resolution reproduction in the US-HR series has been pursued based on TASCAM's policy to recreate sound as close to the original as possible. Therefore, the in-house developed Ultra HDDA mic preamp combined with a newly improved audio circuit delivers enhanced audio performance with the most transparent and low-noise sound.
Zero-latency direct monitoring function
Direct monitoring will diverge signals before sending them to the computer, resulting in smooth, in-time monitoring without any sound delay during both recording and performance.
Create quality content with bundled software
The US-HR models come bundled with world-renowned software that will enhance the user's production workflow. At the core of music production, Steinberg's Cubase LE/Cubasis LE 3 DAW is included, along IK Multimedia's Sample Tank SE, which comes free of charge with a massive 30 GB sound library encompassing more than 2,000 different musical instruments.
US-HR models also come with a free 3-month subscription to Auto-Tune Unlimited, a comprehensive suite of industry standard pitch correction and vocal effects.
Interface for podcasts and live streaming
The US-4x4HR can be used with computers or smartphones to easily create podcasts or live streams. The audio can be switched between stereo/mono, and the loopback function allows the audio from the computer to be returned to the streaming software for playback during live streams. US-4x4HR also supports OBS, which is popular and used worldwide.
Additional Features
In "loopback mode" for live streaming, IN 3/4 also support stereo / monaural mix. (Added in V1.10)
