Description
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.
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.
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.
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.
Note : About the number of days remaining displayed in Sample Tank 4 SEThe "XXX days left" message shown on Sample Tank 4 SE Project Manager refers to the download deadline of the sound library, and not the expiration time of usage. The sound library available in the IK Multimedia user area has a 180-day expiration date, so we recommend downloading it before the expiration date.
Please contact IK Multimedia for more information and support regarding Sample Tank 4 SE.
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.
In "loopback mode" for live streaming, IN 3/4 also support stereo / monaural mix. (Added in V1.10)
The MIDI IN/OUT terminals allow for other MIDI external devices such as keyboards, drum machines, controllers, etc. to be synchronized and controlled.
The US-4x4HR can be used as an interface for iPad and other iOS devices.
Capitalizing on our experience of being one of the pioneers in manufacturing USB audio interfaces, we achieved further stability in our native driver. The audio buffer size can be set starting from 4 samples (Windows only) to give the best performance to every different environment; maximizing the capability of the computer in use while creating a low-latency environment.
The US-HR models share a solid and practical design that has been applied to withstand long hours of hard use. Its robust metal jacket not only improves its durability but, combined with dye-cast aluminum side panels, provides a sleek and eye-catching design. In addition, all models have just the right weight, so they won't move when cables are connected or disconnected.
