The Audio Maintenance EZ1073-500 module is a dual-slot mono 500 Series hand-built Class A preamp and EQ module inspired by original 1073 unit.
Hand-made in Britain, the Audio Maintenance EZ1073-500 offers exceptional quality and a great sounding preamp and EQ for your 500 Series rack. Not surprising when you consider that it is derived from the legendary Neve 1073, but surprising when you read the comments by users that rate it alongside the original units.
To do that, Audio Maintenance built the EZ1073-500 with the finest components it could source, including the large output transformer, previously seen as a bar to making a 500 Series version - the microphone and line inputs have their own separate circuits too, including transformers - the Carnhills used throughout the EZ1073-500. The EQ section is comprehensive and it comes with phantom and phase reversal switches.
The quest for sonic nirvana is a restless one and fashions come and go, but the pursuit of classic Neve-type EQs seems never-ending and the Audio Maintenance EZ1073-500 is destined to soon become a classic in its own right.
