8424E motorised fader console + 3x 1073OPX Octal mic preamp bundle

24 Channels of External 1073 Preamplification
Three included 1073OPX units provide a dedicated microphone preamp for every console channel, supplementing the console’s two onboard 1073 preamps.

Marinair Transformer Signal Paths
Transformer-coupled OPX microphone inputs and the console’s voltage-mixing stereo bus bring Neve analogue character to recording and summing.

Motorised Faders with Dual-Layer Control
Switch between analogue level control and DAW fader control from the console surface.

DAW-Driven Analogue Automation
Active Fader mode transfers DAW fader positions to the analogue layer for post-processing level automation during mixdown.

Integrated OPX Control
Control all three included OPX units from the console surface, with displayed gain levels and input types.

Console Recall and OPX Total Recall
Store console settings and restore routing, soft switches and motorised fader positions automatically. The OPX units support automatic recall of their settings.

Independent Recording and DAW Inputs
Keep recording sources and DAW returns connected simultaneously, with dual-layer operation supporting expanded mixing capacity.

Channel Inserts and Direct Outputs
Balanced inserts integrate external processing, while digitally controlled direct outputs provide individual channel recording feeds.

Group and Mix Bus Processing
Four mono groups provide EQ, inserts and direct outputs. Master bus EQ and stereo width processing add control over the final mix.

Mic, Line and Instrument Inputs
Each OPX channel offers separate input choices and gain settings, including a transformerless Class-A instrument input.

Precise Preamp Adjustment
Stepped gain, switchable impedance, phantom power, pad, polarity reversal and high-pass filtering accommodate different microphones and sources.

Flexible Cue and Effects Routing
A stereo cue send, three mono auxiliaries and dual stereo reverb returns support performer mixes and external effects.

Comprehensive Monitoring and Communication
Three stereo speaker outputs, independently sourced headphone outputs and three-way talkback support collaborative sessions.

Hands-On DAW Operation
Transport, automation and rotary controls provide access to supported DAW functions, including pans, sends and plug-in parameters.

Expandable Elements Processing
Optional 88R EQ, 1084 EQ and 88R Dynamics processors add digitally controlled analogue processing, with settings managed through the Element Control Plugin or Neve Elements App.
