OVERVIEW

Introduction

Thank you for purchasing this Scarlett 2i4, one of the family of Focusrite professional computer audio interfaces incorporating high quality Focusrite analogue pre-amplifiers. You now have a simple and compact solution for routing high quality audio to and from your computer.
This User Guide provides a detailed explanation of the hardware to help you achieve a thorough understanding of the product’s operational features. We recommend that both users who are new to computer recording, as well as more experienced users, take the time to read through the User Guide so that you are fully aware of all the possibilities that the Scarlett 2i4 and accompanying software has to offer. If the main User Guide sections do not provide the information you need, be sure to consult http://www.focusrite.com/answerbase, which contains a comprehensive collection of common technical support queries.

Features

The Scarlett 2i4 hardware interface provides the means for connecting microphones, musical instruments or line level audio signals to a computer running Mac OS or Windows. The signals at the physical inputs can be routed to your audio recording software / digital audio workstation (referred to throughout this user guide as the «DAW») at up to 24-bit, 96 kHz resolution; similarly, the DAW’s monitor or recorded output will appear at the unit’s physical outputs.
Audio sources – mics, instruments, etc. – connected to the physical inputs can be recorded in the DAW and then routed from your DAW to the physical outputs. The 2i4 is equipped with four audio output channels, which can be connected to an amplifier and speakers, powered monitors, headphones, DJ or other type of mixer, or any other analogue audio equipment that you wish to use. Although all inputs and outputs on the Scarlett 2i4 are routed directly to and from your DAW for recording and playback, you can configure the routing within your DAW in order to meet your needs. A Direct Monitoring feature lets you hear what you are playing without the effects of computer latency. The 2i4 also acts as a convenient MIDI interface between your computer and other MIDI equipment.
For DJs, the two pairs of outputs make it simple to interface the stereo output from a laptop running DJ software to two channels of a DJ mixer.

(Note that Scarlett 2i4 is a USB 2.0 device, and thus the USB connection requires a USB 2.0+ compliant port on your computer. It will not operate correctly with USB 1.0/1.1 ports)

Audio Setup in your DAW

Example of Usage

The Scarlett 2i4 is an excellent choice for several different recording and monitoring applications. Some typical configurations are shown below.

Connecting a microphone or instrument

This setup illustrates the most typical configuration for recording with DAW software on your Mac or PC. In this case, you might record guitar through Input 1 and vocals through Input 2 into Ableton Live Lite, while monitoring the playback from the DAW via headphones or loudspeakers.
The front panel input sockets are Neutrik Combo® type, which accept either an XLR male connector (you will probably have one on the end of your microphone cable) or a ¼» (6.35 mm) jack plug. Note the Scarlett 2i4 has no «Mic/line» switch – the Focusrite preamplifier stage is automatically configured for a microphone when you plug an XLR into the input, and for a line or instrument when you connect a jack plug. Set the LINE/INST switch next to the socket to INST if you are connecting musical instrument (a guitar in the example) via an ordinary 2-pole guitar jack, or to LINE if you are connecting a line level source such as the balanced output of an external audio mixer via a 3-pole (TRS) jack. Note the Combo connector accepts both types of jack plug.
If you are using a capacitor (condenser) microphone, press the 48V button to supply phantom power to the mic. Don’t turn this on if you’re using any other type of mic.
Each channel of the Scarlett 2i4 has a PAD button on the front panel; pressing this reduces the input sensitivity by 10 dB. You may find this useful if you are feeding the input from a line level source when the output is particularly «hot».

Using Direct Monitoring

You will frequently hear the term «latency» used in connection with digital audio systems. In the case of the simple DAW recording application described above, latency will be the time it takes for your input signals to pass through your computer and audio software, and back out again via your audio interface. Latency can be a problem for a performer who wishes to record while monitoring their input signals.
The Scarlett 2i4 is fitted with a «Direct Monitoring» option, which overcomes this problem.
Setting the front panel DIRECT MONITOR control to INPUT will route your input signals directly to the Scarlett 2i4’s headphone and main monitor outputs. This enables you to hear yourself with zero latency – i.e., in «real time». Users can vary the amount of computer playback heard by using the DIRECT MONITOR control. The input signals to your computer are not affected in any way by this setting.
DIRECT MONITOR is a «mix» control – it lets you set your own preferred blend of input signals and DAW playback. As you rotate the control clockwise, the level of DAW playback increases and the level of your input signal decreases. At the 12 o’clock position, a 50/50 mix of the two is obtained.
Note that if the DIRECT MONITOR control is set anywhere other than fully clockwise or fully anticlockwise, ensure that your DAW software is not set to route its input (what you are currently recording) to its output. If it is, you will hear yourself «twice», with one signal audibly delayed as an echo.
The Direct Monitoring facility can also be switched for mono operation, which is useful if you are only recording one instrument or voice. With the STEREO/MONO switch set to STEREO, Input 1 is routed to the left input channel and Input 2 to the right, and this will be the correct setting if you are recording a stereo source. In MONO mode, both inputs are routed equally to both channels, and will appear in the centre of the stereo image.

Connecting Scarlett 2i4 to loudspeakers

If connecting 1 and 2 and 3 and 4 to the two decks of a DJ Mixer make sure to turn the Monitor Knob all the way up to send a full line signal to 1 and 2, Deck A. Output channels 1 and 2 are provided both in variable-level, electronically balanced form on ¼» (6.35 mm) 3-pole (TRS) jacks and as unbalanced signals on phono (RCA) sockets. Outputs 3 and 4 are provided in fixed-level unbalanced form only, also on phono (RCA) sockets.
If Outputs 1 and 2 are used, Outputs 3 and 4 are free to be used for another purpose, such as connecting to an additional recording device or an additional pair of monitors. However, please note that the balanced versions of channels 1 and 2 – i.e., the signals at the two ¼» (6.35 mm) jack sockets and the unbalanced versions of channels 1 and 2 – are affected in level by the the large front panel MONITOR volume control. The signals at outputs 3 – 4 phono (RCA) sockets are at (full) fixed level, and thus if you use these for monitoring, you will have to control the volume either at source (within the DAW itself), or by adjusting the volume on an external amplifier.
Self-powered monitors (i.e., typical computer speakers) incorporate internal amplifiers with a volume control, and may be connected directly. Larger, passive loudspeakers will require a separate stereo amplifier; in this case, the outputs should be connected to the amplifier’s inputs.

Typical consumer (hi-fi) amplifiers and small powered monitors will have unbalanced inputs, either on phono (RCA) sockets, or via a 3.5 mm 3-pole jack plug intended for direct connection to a computer. In either case, use a suitable connecting cable with phono plugs (RCA jacks) at one end. Hi-fi amplifiers and powered monitors will have their own volume controls; use these to adjust the monitoring volume.
Professional power amplifiers will generally have balanced inputs (either on 3-pin XLR or 3-pole (TRS) ¼» (6.35 mm) jack sockets); use a suitable cable to connect them to the ¼» jack outputs of the Scarlett 2i4. If you use the balanced outputs, you can adjust the monitoring volume from the Scarlett 2i4’s front panel.
NOTE: You run the risk of creating an audio feedback loop if loudspeakers are active at the same time as a microphone! We recommend that you always turn off (or turn down) monitoring loudspeakers while recording and use headphones when overdubbing.

Connecting Scarlett 2i4 to a DJ mixer

The Scarlett 2i4 makes an excellent interface between a laptop running DJ software and the channels of a DJ mixer. In this setup, Outputs 1 and 2 can be connected to Line Inputs 1 and 2 of an external DJ mixer, and Outputs 3 and 4 to Line Inputs 3 and 4. Connecting in this way means that all mixer facilities, such as EQs and crossfading, are easily accessible. If connecting 1 and 2 and 3 and 4 to the two decks of a DJ Mixer make sure to turn the Monitor Knob all the way up to send a full line signal to 1 and 2, Deck A.

HARDWARE FEATURES

Front Panel

The Front Panel includes the input connectors for Mic, Line and Instrument signals, as well as the input gain and monitoring controls.

1. Inputs 1 & 2 – Neutrik Combo® input sockets — connect microphones, instruments (e.g., guitar), or line level signals via XLR or ¼» (6.35 mm) jacks as appropriate.
2. GAIN 01 and GAIN 02 — adjust the input gain for input signals on inputs 1 and 2 respectively. The gain controls have concentric bi-colour LED ‘rings’ to confirm signal level: green indicates an input level of at least -24 dBFS (i.e., ‘signal present’), the ring then turns red when signal level reaches 0 dBFS.
3. PAD – 10 dB pad for each input. Pressing this button reduces the sensitivity of the input; use if feeding the input with a particularly high-level signal.
4. LINE/INST — Instrument/Line level switches for each input – switches gain to suit instrument or line level signals.
5. 48V — phantom power switch for mic inputs — enables 48 V phantom power at XLR contacts of both Combo connectors.
6. USB LED — illuminates when the unit receives USB bus power and is confirmed by the computer as connected and operating correctly.
7. MIDI LED – illuminates when MIDI data is received at the MIDI IN port.
8. DIRECT MONITOR – rotary «blend» control letting you set your monitor mix as a balance of the input signal(s) and the DAW playback.
9. STEREO/MONO – selects whether the inputs are summed to mono for monitoring.
10. MONITOR – main monitor output levels control – sets the output level at the balanced and unbalanced (rear panel) outputs of channels 1 and 2 on both the TRS and RCA connectors.
11. Headphone level — adjusts the output level at the front panel stereo headphone output.
12. HEADPHONE SOURCE – allows you to select whether the headphones output is fed from Outputs 1 and 2 or Outputs 3 and 4 (as stereo pairs; modified by the setting of [9]).
13. Headphone socket — ¼» TRS output jack — connect your stereo headphones here.

Back Panel

1. Kensington security lock – secure your Scarlett 2i4 to a suitable structure if desired. Please see http://www.kensington.com/kensington/us/us/s/1704/kensington-security-slot.aspx for further information on how to use this feature.
2. USB 2.0 port – Type B connector; connect to your computer with cable supplied.
3. MIDI IN and MIDI OUT – standard 5-pin DIN sockets for connection of external MIDI equipment such as keyboards or sound modules. The Scarlett 2i4 provides a convenient MIDI interface with your DAW, making a computer MIDI card unnecessary.
4. Line outputs 1 and 2 — 2 x ¼» (6.35 mm) TRS jack sockets; +4 dBV output level (variable), electronically balanced. Either ¼» TRS (balanced connection) or TS (unbalanced connection) jack plugs can be used.
5. Line outputs 3 and 4 – 2 x phono (RCA) sockets; unbalanced outputs, -10 dBV level (fixed).
6. Line outputs 1 and 2 – 2 x phono (RCA) sockets; unbalanced outputs, -10dBV level (variable).
7. These sockets carry the same signal as [17] at all times.

ВВЕДЕНИЕ

Это руководство пользователя программного обеспечения Focusrite Control, которое предназначено для использования с USB-аудиоинтерфейсами Focusrite Scarlett 3-го поколения.

Если вы только что приобрели интерфейс Scarlett 3-го поколения, то вам потребуется как данное руководство пользователя, так и руководство пользователя аппаратуры. Руководство пользователя аппаратуры можно скачать по адресу Downloads | Customer Portal.

Сочетание великолепных характеристик звукового тракта и профессионального качества изготовления Scarlett с простым и интуитивно понятным интерфейсом Focusrite Control позволяет создать универсальную систему компьютерной записи, используя предпочитаемую цифровую звуковую рабочую станцию (DAW).

Хотя программа Focusrite Control является максимально интуитивно понятной и ориентированной на решение конкретных задач, любой пользователь найдет в этом руководстве полезную информацию, так как полное понимание особенностей программного обеспечения возможно лишь при его рассмотрении в сочетании с подключенной аппаратурой.

ВАЖНАЯ ИНФОРМАЦИЯ

Ассортимент интерфейсов Scarlett включает несколько разных моделей, и все они поддерживают Focusrite Control. Фундаментальное различие между этими моделями заключается в количестве доступных входов и выходов, а также в наборе функций, которыми можно управлять напрямую из Focusrite Control.

Focusrite Control распознает конкретную аппаратуру Scarlett, подключенную к компьютеру, и настраивается соответствующим образом. Поэтому на экране будут отображаться лишь те входы и выходы, которые фактически поддерживаются используемой аппаратурой.

Благодаря этой автоматической настройке данное руководство пользователя применимо ко всем моделям в ассортименте Scarlett, хотя большая часть информации в нем применима к старшим моделям в ассортименте Scarlett, а именно Scarlett 4i4 и выше (см. ПРИМЕЧАНИЕ ниже). Так как включение в руководство снимков экранов для разных моделей может запутать читателя, мы решили использовать в качестве «базовой» модели устройство Scarlett 18i20. Если вы приобрели Scarlett 18i20, то снимки экранов в данном руководстве пользователя будут в точности соответствовать реальным экранам. При использовании другой модели существенные различия в виде экрана будут заключаться лишь в количестве доступных входов и выходов, а также в функциях, управляемых программным обеспечением.

ПРИМЕЧАНИЕ . Только для пользователей Scarlett 2i2 и Solo

Хотя программное управление для данных моделей ограничено, установка Focusrite Control все равно необходима для обеспечения полной функциональности устройства при частотах дискретизации выше 48 кГц, а также для обновлений микропрограммы. Однако в целом для использования аппаратного интерфейса нет необходимости запускать Focusrite Control на компьютере. Обратите внимание, что в будущем будут доступны новые функции, управляемые программным обеспечением.
