The specific Input Channel will vary depending on your interface and Sample Rate. Below are the input channels for Scarlett 3rd Gen interfaces at a Sample Rate of 44.1-48kHz. For more information, see the Focusrite Control User Guide for your specific interface. This integrated input design for the gain controls is visualized by the circular lights that wrap around each gain knob. Price

This voltage is commonly referred to as phantom power. Note that, even with phantom power on, the mic's signal will still need pre-amplification; the 48V supply is simply there to charge the condenser mic's capsule and power active electronic components. Ribbon Microphones Focusrite got its start in the 1980’s building consoles for recording studios. Since then, they’ve expanded in the music industry, producing audio interfaces for music producers. The controls and knobs on the front are also of high quality, made of both aluminum and durable plastic. The MIDI in/out makes the audio interface compatible with old keyboards and synthesizers. I’d say this feature is necessary for some recording artists and producers. The time it takes for the sound of a snare drum to reach a drummer's ears, is about 2.1 milliseconds.Both versions of the Scarlet are pretty close in size. But the 2i4 is a bit bigger and heavier because it comes with more hardware. Our compact and flexible 2-in, 4-out USB audio interface makes it easy to perform and record studio-quality audio against a cue mix. Take it anywhere, connect and power by USB and get two natural-sounding Scarlett mic preamps, super-low latency, MIDI I/O, four analogue outputs and the same class-leading sound quality and digital conversion as the rest of the Scarlett range. If you have set a buffer size of 512 samples. The amount of time (milliseconds) 512 samples equates to, depends on how long it takes for 512 samples to be processed. Scarlett 2i4 delivers high quality, 24-bit 96kHz audio to and from both Macintosh and Windows computers with USB 2.0 capability - and it's bus powered so you only need to plug in the included USB cable to start making music. If these things matter to you, then the 2i4 is the one to get despite the price increase. If not, then the 2i2 is the more affordable way to go.

Focusrite Overview:Scarlett 2i4 is the latest in Focusrite's new generation of USB interfaces alongside the popular 2i2 and other products in the series. This 2-in, 4-out USB audio interface combines affordability, cross-platform operation, a comprehensive feature set and the best audio performance in its class. It's a perfect match for both the musician and the digital DJ - and it comes in an elegant, road-ready anodised aluminium unibody case. You get a MIDI in/out, the pad button, and a 4-channel output, none of which are available on the 2i2 The 2i4 weighs a little over half a pound more and is slightly bulkier. This is the major trade-off that comes with having more features. If you're having problems installing the driver on Windows 7, please try the steps in the following article: Focusrite USB Driver will not install on my Windows 7 machine (digital signature problem).Buying either of these Focusrite Scarlett models also give you access to the same bundle of plug-ins and software. The latency that you set using your buffer size (and sample rate) is not the latency that impacts the sound by the time it reaches your ears. Other sources of latency include: They are the same interface in terms of looks and functionality, BUT — the latter has more features that offer sound engineers more possibilities whenrecording. The 2i4 goes beyond, though, and adds 4-channel stereo output and MIDI in/out. The 4-channel output is useful because it allows you to listen via headphones.

The term 'Ultra-low' is used as audio interface hardware/firmware induces a negligible amount of latency. We'll use the term 'Zero-latency' to avoid confusion. Equivalent Input Noise (EIN) < -120dB: measured at 55dB of gain with 150Ω termination (20Hz/22kHz bandpass filter) Part of the time this takes is the 'buffer size', which you can set yourself. You can adjust the buffer size for your needs. Using a lower buffer size (and therefore getting less latency) gives your CPU less time to process the audio and therefore the CPU must work harder to process the audio in time.Due to this phantom powering, these Scarlett audio interfaces will need more than a laptop battery to power them up and keep them running throughout your recording session. For minimal latency input monitoring the Solo includes a single function Direct button, and the 2i2 is a dual-function Direct button, with mono and panned options. The 4i4 has no hardware option but has 3 software cue mixes, accessible via Focusrite Control 2.

A buffer size that is set in samples equates to a certain amount of time, but that amount of time is dependent on the sample rate (the number of samples recorded per second). The higher the sample rate, the less time (milliseconds) that the buffer size equates to.In the window that opens, you can then select any additional channels that you wish to expose to non-ASIO applications ( in the example below we'll expose Analogue Inputs 3 + 4): Please note that if you're using an application that includes ASIO support (e.g. Pro Tools, Ableton Live, Cubase, Studio One, Reaper etc) then all input and output channels will be available to you by default, this article may not be applicable. The Scarlett 2i2 and 2i4 are both manufactured by Focusrite, an English company that specialize in producing top-quality audio recording equipment. If you're sat 1m (just over an arm's length) from your speakers then the latency between the sound from your speaker and your ear is 3.4ms.
