AMS Neve 1073SPX-D - The World’s First Genuine 1073® Interface


AMS Neve 1073SPX-D - The World’s First Genuine 1073® Interface

The 1073SPX-D merges the renowned 1073® preamp with a robust digital audio interface, featuring USB and ADAT connectivity.

Digital Innovation

The 1073SPX-D seamlessly integrates a complete 1073 channel strip with a robust digital audio interface. USB and ADAT digital connections transform the 1073SPX-D into a versatile one-stop solution for recording, mixing, and monitoring in any studio, live sound or mobile recording setup.

9x12 Audio Interface

The 1073SPX-D features nine inputs (1x analogue/8x ADAT) and 12 outputs (4x analogue/8x ADAT). These expandable I/O capabilities allow the 1073SPX-D to become the main focal point of your studio, with all of your studio tools connecting to your DAW through the 1073SPX-D.

Class-Compliant USB

The 1073SPX-D’s innovative USB digital interface uses class-compliant drivers, offering a simple ‘plug & play’ setup for studio integration or on-the-road recording. By connecting the 1073SPX-D directly to your PC or Mac via USB, you can access all of the unit’s analogue features directly from the DAW of your choice.

ADAT Expansion Options

The 1073SPX-D features ADAT input and output ports that can function in two distinct modes. In USB/ADAT hub mode, additional units (such as the 1073OPX or a second 1073SPX-D), can connect together via ADAT, increasing the unit’s recording, mixing, and monitoring capability. In ADAT Audio Expander mode, the 1073SPX-D can function as a standalone ADAT expander connected to your existing audio interface, integrating a complete 1073 channel strip into your current system with ease.

Digital Hardware Insert

The 1073SPX-D’s digital option allows the unit to be applied as a hardware insert into your computer. Any track in your DAW can now be routed through the 1073SPX-D’s analogue circuitry, including Marinair transformers, Inductor EQ, and more, and returned to your DAW via USB or ADAT.

New Monitoring Options

The 1073SPX-D monitoring controls and connections allow studio loudspeakers and headphones to be directly connected to the unit, with attenuation and loudspeaker cut for total control over your monitoring setup. Two stereo DAW sources can be monitored, and a unique blend control allows for latency-free monitoring of the 1073SPX-D recording signals along with the stereo DAW tracks.

Class-A Discrete Design

The 1073SPX-D retains the discrete, class-A topology & exclusive Marinair transformers (input and output stages), to produce that classic 1073 sound. The 1073SPX-D uses a combination of modern production techniques, including our unique, in-house SMT, with the discrete audio path constructed using through-hole methods, including hand-mounting of the Marinair transformers and class-A transistor-based amplifiers.

1073® Gain Staging

The classic 5dB stepped Elma switch delivers accurate gain levels throughout the gain range, and this unique layout means there is no need for a mic/line switch, the pot itself selects the preamp and input. Three distinct gain stages provided by two independent transistor-based preamplifiers provide gain for any DI, line input or microphone signal.

Inductor-Based EQ

The three-band inductor based EQ is designed for musicality. Rupert Neve and his team of Engineers carefully selected each frequency point to enhance sound quality across the frequency spectrum. The custom hand-wound inductors are made in the UK and are exclusive to Neve, often exceeding our tight 1073 specification.

Flexible Analogue I/O

The 1073SPX-D includes a host of analogue I/O to accommodate all potential workflows. Switchable front and rear connections allow for total studio integration and quick-access recording. A balanced insert send and return loop with a flexible insertion point enables analogue expansion with additional hardware units such as compressors and a rotary output fader with a -inf to +5dB range gives total control over the unit’s output signal via its XLR output connection.
