Introduction

Thank you for purchasing this Clarett+ 8Pre, a high-performance and immensely capable studio

centrepiece for PC or Mac. Eight next-generation, high-headroom, low-noise, low-distortion Clarett+

mic preamps - featuring the unique All-analogue Air function - help you capture superbly clear

recordings, and independent A-D and D-A converters with improved dynamic range bring you closer

than ever to your music.

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 you take the time to read the

Guide, so you are fully aware of all the features the Clarett+ 8Pre has to offer.

IMPORTANT: As well as this User Guide, you will need the Focusrite Control Software

Guide which can be downloaded from focusrite.com/downloads.

This contains full details of Focusrite Control, the software application designed

specically for use with the Focusrite Clarett+ range of interfaces.

If either User Guide does not have the information you need, please go to

support.focusrite.com, where you can nd articles and tutorials beyond the scope of this

user guide. A Getting Started video tutorial is also available, at

focusrite.com/get-started/ClarettPlus-8Pre.

Features

The Clarett+ 8pre has eight next-generation, high-performance Clarett+ preamps to capture clear

and powerful sounds with a preamp design that brings masses of headroom, low distortion and low

noise. New and improved high-performance A-D and D-A converters maintain the purity of analogue

and deliver extremely low noise and high dynamic range.

Vocals will shine with the All-analogue Air, its analogue circuitry emulating the classic Focusrite

ISA 110 preamp. J-FET instrument inputs offer dedicated, ultra-high-impedance, extremely wide

audio bandwidth, and mimic guitar amp inputs to preserve the natural tone of guitars.

The accompanying software application, Focusrite Control, is designed to let you easily congure the

Clarett+ 8Pre with signal routings appropriate for most common recording tasks. For more complex

situations, it provides extensive routing and monitoring options, as well as the ability to control global

hardware settings such as sample rate and synchronisation. You can download Focusrite Control

from focusrite.com/downloads.

iPad and iPhone users can additionally download Focusrite iOS Control from the App Store®. The

app communicates via WiFi with Focusrite Control running on your computer, and lets you adjust

your monitor mixes and input settings from your iOS device. See the Focusrite Control User Manual

for more information.

Box Contents

Along with your Clarett+ 8Pre you should have:

• AC mains cable with IEC connector

• USB-C to USB-A cable

• USB-C to USB-C cable

Focusrite Control is available at focusrite.com/downloads. On Windows, Focusrite Control will

also install the driver required. Mac users: Clarett+ 8Pre is class-compliant on Macs, therefore no

drivers are required.

As a Clarett+ owner, you are also entitled to a selection of third-party software.

Hardware Features

Front Panel

The front panel includes all input gain and monitoring controls as well as two input connectors for

Mic, Line and Instrument signals.

1. INPUTS 1 & 2– Combo XLR input sockets - connect microphones, instruments (e.g., guitar), or

line level signals via XLR or ¼” jacks as appropriate. Either TRS (balanced) or TS (unbalanced)

jack plugs can be used for instruments or line level signals.

2. 48V – two switches enabling 48 V phantom power at the Combo connectors’ XLR contacts

for mic inputs 1-4 and 5-8 respectively. (Note that inputs 3 to 8 are on the rear panel.) Each

switch has a red LED to show when phantom power is enabled. Note that not all microphones

require phantom power. If you are unsure whether your microphone needs it to work, please

read the microphone documentation.

3. Gain 1to 8– eight rotary controls: adjust input gain for signals at Inputs 1 to 8 respectively.

4. INST – two red LEDs which illuminate when Instrument mode is selected for the jack

Inputs 1 or 2 from Focusrite Control software. When INST is selected, gain range and input

impedance are altered (relative to LINE), and the input is made unbalanced. This optimises

it for connecting instruments directly via a 2-pole (TS) jack plug. When INST is off, you can

connect line level signals. Line level signals may be connected either in balanced form via a

3-pole (TRS) jack or unbalanced, via a 2-pole (TS) jack.

5. AIR – eight yellow LEDs – one per input - which illuminate when AIR function is selected

for the input from Focusrite Control. AIR modies the input stage’s frequency response to

model classic, transformer-based Focusrite ISA mic preamps.

6. Meters – ten 6-segment LED bargraph meters indicating a) the signal levels of the eight

analogue input signals (meters 1to 8), and b) the signal levels at the MONITOR 1and 2

outputs (meters Land R). The input meters show signal level after the input gain stage. The

output meters show signal level before the monitor level control [10], which therefore does

not affect their indication. The LEDs illuminate at -42 (green, “signal present”), -18 and -12

dBFS (green), -6 and -3 dBFS (yellow) and 0 dBFS (red). 0 dBFS implies digital clipping, and

should always be avoided.

7. (USB active) – a green LED which illuminates when the unit has established a connection

with the computer to which it is connected.

8. MIDI – a green LED which illuminates when MIDI data is being received at the rear panel

MIDI IN port.

9. (Locked) – a green LED which conrms clock synchronisation, either to the Clarett+ 8Pre’s

internal clock or to an external digital input.

10. MONITOR – main monitor output level control – this control will normally control the level at

the main monitor outputs on the rear panel, but can be congured in Focusrite Control to

adjust the level of multiple pairs of outputs.

11. DIM and MUTE – two switches controlling the Clarett+ 8Pre’s monitor outputs; DIM reduces

the output levels by 18 dB, while MUTE turns the outputs off. By default, these switches affect

the main monitor outputs 1 and 2, but may be congured in Focusrite Control to act on any

of the analogue outputs. The switches are internally illuminated (DIM: yellow, MUTE: red)

indicating the function is selected.

12. (Headphones) 1and 2 – connect one or two pairs of stereo headphones at the two ¼” TRS

jack sockets below the controls. The headphone outputs always carry the signals currently

routed to analogue outputs 7/8 and 9/10 (as stereo pairs) in Focusrite Control.

13. POWER – AC power switch and LED.

14. Rack ears for mounting the Clarett+ 8Pre in a standard 19” equipment rack.

1. MIC/LINE INPUTS 3 to 8– Combo XLR input sockets - connect further microphones or line

level signals via XLR or ¼” jacks as appropriate. Either ¼” TRS (balanced) or TS (unbalanced)

jack plugs can be used for line level signals.

2. LINE OUTPUTS 3to 10 – eight balanced analogue line outputs on ¼” jack sockets; use TRS

jacks for a balanced connection or TS jacks for unbalanced. Signals routed to these outputs

are dened in Focusrite Control, for driving alternative speakers (i.e., mideld, neareld,

etc.), the additional speakers in a multichannel monitoring system, or to send audio to

outboard FX processors.

3. MONITOR 1 and 2– two balanced analogue line outputs on ¼” jack sockets (with “anti-

thump”); use TRS jacks for a balanced connection or TS jacks for unbalanced. These are also

Line Outputs 1 and 2, and will generally be used for driving the main L and R speakers of your

monitoring system. However, output routing may be customised in Focusrite Control.

4. OPTICAL IN and OUT – two TOSLINK connectors, each carrying eight channels of digital audio

in ADAT format at 44.1/48 kHz sample rate or four channels at 88.2/96 kHz. This input is also

capable of accepting a stereo optical S/PDIF source: this option is selected from Focusrite

Control. Note that this input is disabled at sample rates of 176.4/192 kHz.

5. WORD CLOCK OUTPUT – a BNC connector carrying the Clarett+ 8Pre’s word clock; this may

be used to synchronise other digital audio equipment.

6. – USB connector; connect the Clarett+ 8Pre to your computer with a USB cable.

7. MIDI IN and MIDI OUT – standard 5-pin DIN sockets to connect external MIDI equipment. You

can send/receive MIDI data between your computer and external MIDI devices.

8. SPDIF IN and OUT – two phono (RCA) sockets carrying two-channel digital audio signals in

and out of the Clarett+ 8Pre in S/PDIF format. Like all other inputs and outputs, the routing of

S/PDIF signals may be customised in Focusrite Control.

9. AC mains – standard IEC (AC) connector. The Clarett+ 8Pre is tted with a “Universal” power

supply, and will run from any AC mains voltage from 100 to 240 V, at 50 or 60 Hz.
