Equally capable for tracking vocals and instruments, the two improved Scarlett microphone preamps feature switchable phantom power for condenser mics, pads to prevent distortion on loud input signals, and a selectable-per-channel Air circuit, which adds clarity-enhancing brightness based on Focusrite’s legendary ISA preamplifier.
The two XLR-1/4″ combo inputs are outfitted with switches that allow them to accept signal directly from electric instruments such as guitar and bass, from line-level sources such as stereo mixer outputs, or from a hot feed from a drum machine. The rear panel sports two additional fixed-level 1/4″ inputs to accommodate more line-level sources such as the outputs of external mic preamps.
Unlocking the ability to record at standard CD quality or high-fidelity resolutions, the 24-bit / 192 kHz AD/DA converters ensure that signals are captured and reproduced with detail and accuracy. With four balanced 1/4″ line outputs, a 1/4″ stereo headphone jack, and independent control of the headphone and speaker volume settings, the Scarlett 4i4 can simultaneously feed multiple monitoring systems or outboard effects processors.
The virtual loopback function on the Scarlett 4i4 empowers podcasters with an easy mix-minus setup for taking calls without the caller being distracted by a delayed audio return signal. Also, traditional 5-pin MIDI I/O is provided for seamless integration of MIDI equipment such as a keyboard or sound module. You can even utilize your iPad, iPhone, or iPod touch to wirelessly control the Scarlett 4i4.
With its bus powering for uninhibited portability, space-saving USB-C connection, and extensive software bundle including elementary versions of Ableton Live and Avid Pro Tools music production workstations, virtual instruments, plug-in effects, loops, and more, the Scarlett 4i4 gives you plenty of powerful tools to kick-start your inspiration. Just plug the Scarlett 4i4 into your Mac/Windows computer, fire up your preferred audio recording software, and let the creativity flow.
Hook up an electric guitar to one of 4i4’s Hi-Z instrument inputs — it feels just like an amp. Plug synths and grooveboxes straight into the super-high-quality line inputs. Connect your favourite outboard gear to the additional line outputs. You’ve even got MIDI.
