AMS Neve | 1073DPX 2-Channel Preamp and 3-band EQ

1073DPX

Twice the Neve Punch

The 1073DPX has two channels of 1073^® Class A design microphone preamplifiers, each with 3-band EQ (fixed HF plus two switchable bands with cut/boost capability) and a high pass filter.

Dual Modern 1073's

With two 1073^® pre-amps packed into a modern, 2u 19″ rack format, the 1073DPX features everything you need to record a variety of performance setups. For example, stereo micing setups such as piano or drums work perfectly through the dual-channel DPX. Alternatively, singer-songwriters can use each channel strip independently for an acoustic guitar and a vocal simultaneously.

Marinair^® Transformers

Exclusive Marinair^® transformers are used on the input and output stage to produce that classic 1073^® sound; the line and mic inputs are transformer-balanced.

Class A Discrete

The 1073DPX retains the discrete, class-A topology made famous by the classic 1073^®. Taking this technology forward, the 1073DPX uses a combination of modern production techniques, including our unique, in-house SMT. Still, crucially, the discrete audio path is constructed using through-hole methods, including mounting the Marinair^® transformers and class-A transistor-based amplifiers.

Unique 1073^® Gain Staging

The classic 5dB stepped Elma switch delivers accurate gain levels throughout the gain range. 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.

High Output - Harmonic Saturation

By combining the two preamps together, the 1073^® preamp can deliver up to 80dB of microphone gain, bringing out the musical drive and harmonic saturation that the 1073 is famous for.

Dual Instrument DI's

The 1073DPX features two instrument DI’s, one for each channel. This layout is ideal for capturing a duet instrumental performance in the studio without any peripheral equipment.

Front & Rear Inputs

With independent switching of front and rear inputs, the 1073DPX can be integrated into your studio, ready to use as an insert or through a patch bay, with switchable front combi-connectors for recording directly into the front of the unit.

Inductor-Based EQ

The three-band inductor based EQ is designed for musicality. Each frequency point was carefully selected by Rupert and his team of engineers 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.

Unique Insert Loop

Expand the 1073DPX channel strips with the balanced, +4dBu insert send/return loop feature. This circuit is designed for ultimate flexibility with a switchable pre/post EQ insertion point. Create custom on-the-fly signal flows with any of your favourite outboard processors or stomp pedals.

Rotary Output Fader

The rotary level pots function independently, just like the two-channel faders on a Neve^® console. Running from -inf to +5, this control gives plenty of headroom for fine-tuning your recording signal back into the DAW.

Variable-Point Metering

For further precision, the 1073DPX features two independent 7-stage LED meters using PPM ballistics. Each meter displays signals between -33dB to +24dB at variable points throughout each signal chain, I/P shows how much gain is added after the preamp stage, EQ displays overall gain reduction/addition at the inductor EQ stage and O/P displays the final output gain – perfect control over signal flow for each preamp.

Mono/Stereo Monitoring

The 1073DPX included headphone monitoring mounted to the front of the unit. This feature provides latency-free mono or stereo monitoring for tracking and an independent preamp output for signal splitting. Additionally, it also allows you to jam through one or both channels of the 1073DPX without any recording equipment powered on.
