The Focusrite Scarlett OctoPre Dynamic is an eight-channel microphone preamplifier with per-channel analog compression, 24-bit/192kHz AD/DA conversion, and bidirectional ADAT optical I/O. It expands any ADAT-equipped interface with eight additional mic/line inputs and eight analog outputs.

Built-In Compression

The OctoPre Dynamic builds on the standard OctoPre by adding a soft-knee VCA compressor to every input channel and full D-A conversion through its ADAT inputs. Each channel has a single-knob Compress control that sets the threshold, and a "More" button that doubles the compression ratio for more aggressive dynamics control. A gain reduction LED on each channel confirms when compression is active.

Flexible Output Routing

The eight balanced line outputs can be sourced from the mic preamps (for live sound) or from the ADAT inputs (for routing DAW tracks to an analog console). This ADAT-to-LINE mode makes the OctoPre Dynamic a flexible expansion for both recording and mixdown.

Compression

• Soft-knee VCA compressor on all 8 input channels
• Single-knob threshold control per channel
• "More" button doubles the compression ratio
• Gain reduction LED per channel

ADAT I/O

• 4 TOSLINK optical connectors (2 input, 2 output)
• 8 channels at 44.1/48 kHz
• 8 channels at 88.2/96 kHz (channels 1-4 and 5-8 on separate ports)
• 4 channels at 176.4/192 kHz (channels 1-2 and 3-4 on separate ports)
• ADAT-to-LINE mode routes incoming digital audio to the 8 analog outputs
• Word Clock I/O (BNC) for external synchronization
