Overview

8 Channels, 8 Compressors, 24-bit/96kHz ADAT Input/Output

Description

The OctoPre MkII Dynamic from Focusrite provides 8 channels of Focusrite microphone pre-amplification, 8 VCA-based Red 3-derived compressors, and built-in 24-bit/96kHz digital inputs and outputs. The unit can act as a feature-rich expansion upgrade for any digital audio workstation, or for any analogue or digital console or hard disk recorder.

The Compressors are based on a feed-forward VCA design, derived from the Focusrite Red 3 hardware compressor. With just a single dial, the 8 'recording' compressors allow the user to quickly achieve the desired amount of compression for each channel, providing a natural but loud sound. The single dial solution decreases the threshold and increases the makeup gain simultaneously.

The compressors use a soft-knee progressive compression curve and feature a fixed attack time and release time. The compressor has two modes - "Normal" and "More". These settings let you change the behaviour of the compressor to suit different instruments, with the "More" button doubling the ratio from 2:1 to 4:1, while shifting the threshold range.

Key Features

  • 8 award-winning Focusrite pre-amps form the foundation of this device, with pre-amps optimised to handle extreme levels from sound sources like acoustic drums
  • 8 "single-dial" VCA-based, feed-forward compressors deliver the right amount of compression, fast - based on the character of the celebrated Focusrite Red 3
  • Soft-knee design achieves transparent compression while a "More" switch doubles the ratio to deliver "compression with effect"
  • Built-in 8-channel 24-bit/96kHz digital ADAT intput provides analogue monitoring of any digital ADAT feed, as well as the ability to clock from any ADAT device
  • Built-in 8-channel 24-bit/96kHz digital ADAT output with a "real world" dynamic range performance of 110dB
  • The internal clock delivers a jitter performance of +/-20 PPM
  • Industry-standard JetPLL jitter elimination technology is employed when using external clocks
  • Designed not to clip, the OctoPre MkII is optimised for tracking drums and is able to handle extreme levels from sound sources like kick drums and snares
  • 2 Hi-Z instrument inputs (DI) ready for plugging in guitars and bass
  • Input clip and Compression active LEDs on every channel
  • Fast-acting 5-LED input metres on every channel provide clear reference of input levels, and help to avoid analogue or digital clipping
  • Direct outputs on every channel for routing and flexibility, especially in a live environment
  • +48V Phantom power available on every channel, switched in two groups (1 through 4 and 5 through 8)
  • Internal clocking, master clocking and external clocking via BNC or ADAT
  • 44.1, 48, 88.2 and 96kHz sampling rates
