Focusrite Clarett+ 8Pre USB 18×20 Audio Interface
18-in/20-out USB 2.0 Audio Interface with 8 Mic Preamps and Focusrite “Air” Effect, 24-bit/192kHz Conversion, ADAT I/O, 2 Headphone Outputs, and Included Software Bundle – Mac/PC
Description
Fitur
- x8 Clarett+ preamps offering high performance, low distortion, low noise and lots of headroom
- Fitted with two ultra-high impedance JFET instrument inputs, featuring mimic guitar amp inputs and a seriously broad audio bandwidth
- Relay-controlled analogue circuitry on each preamp replicates Focusrite’s ISA110, swapping impedance to to 2.2kΩ, with the addition of two cumulative high shelves (granting a 4dB increase in higher frequencies)
- Refined A-D and D-A converters characterised by low distortion, high dynamic range, low noise and high performance for precise mixes
- Two enhanced headphone outputs deliver flat frequency response at every output level – no matter your choice of headphones
- An ADAT optical input lets you use your interface alongside ADAT-compatible outboard gear
- Use alongside Focusrite Control – simple (yet deep) software for Mac, PC and iOS
- Register your product and access the Focusrite Plug-in Collective for free monthly plug-ins and discounts
- Comes with a bundle of quality virtual instruments, mixing plug-ins and recording software
