Neve 1073 SPX Legendary Mic Preamp & EQ

The Neve 1073 SPX is a single channel Class A mic preamp and EQ unit in a 1U 19” Rack unit.

Neve delivers the warmth and depth of the classic 1073 and brings the essence of the Neve sound through the 1073 SPX, including the subtle detail and ambience and precise imaging.

Key Features:

• Front and Rear inputs:
  With independent switching of front and rear inputs, the 1073SPX can be integrated into your studio, ready to use as an insert or through a patch bay, with a switchable front combi-connector for recording directly into the front of the unit.
• Class A Discrete:
  The 1073SPX retains the discrete, class-A topology made famous by the classic 1073. Taking this technology forward, the 1073SPX 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.
• Variable-point metering:
  For further precision, the 1073SPX features a 7-stage LED meter using PPM ballistics. The LED meter displays signals between -33dB to +24dB at variable points throughout the 1073SPX’s signal chain. Following on, the I/P shows how much gain is added after the preamp stage, and EQ displays overall gain reduction/addition at the inductor EQ stage and O/P displays the final output gain. This is the perfect control over signal flow throughout the unit.

Specifications:

• General:
  - Genuine 1073 transformer-coupled microphone preamplifier / EQ circuit, in a single 1U 19″ rack-mount enclosure.
  - Exclusive Neve Marinair transformers used on input and output stages
  - Convenient connections for Mic, Line & DI inputs on the front of the unit, with switchable mic/line input connections on the rear of the unit
  - Switchable +48v Phantom Power, Hi/Lo impedance, -20dB pad and DI ground lift on the input stage
  - Switchable Phase and EQ in/out
  - Insert send and return loop feature allows external equipment to be connected easily to the 1073SPX audio chain, such as mono limiter/compressors;
  - Pre-EQ insert send/return – a line level send is available from the mic-preamp output stage and a return just before the EQ stage
  - Post-EQ insert send/return – a line level send is available from the post-EQ stage and a return just before the main output stage
  - 7-stage LED signal level meter – can show mic/line/DI input-stage level, EQ-stage level or output-stage level up to +24dB
  - Output level control
