SCA N72-500 Series Microphone Preamp Module
This is the 500 series module only! It will not work in any of the SCA chassis! There is an SCA only version of the N72 available as well in the Classic series section. The 500 Series kits require voltage measurement and calibration which can be easier with the use of a 500 series extender kit.

Includes an input impedance select switch!
The Seventh Circle Audio N72 delivers the unmistakable character of the highly sought-after Neve single-ended, class A, transformer-coupled console modules. The N72 has become especially popular with digital recordists, since many feel it provides a certain warmth and color that can greatly benefit the hyper-accurate quality of digital recording. The basic circuitry of the N72 is essentially the same as that of the BA183 modules used in the 1272, 1073, and other Neve modules, and from a sonic perspective is virtually indistinguishable from an original Neve. Intended for experienced DIY kit builders only! Available as a DIY kit or fully assembled mic preamp module.
FEATURES
High Gain
The N72 delivers up to 70dB of gain including the voltage step-up provided by the transformers. This is more than enough gain for most applications, especially with modern high-output condenser microphones.
Stepped Gain Control
A 12 position Grayhill switch provides accurate and repeatable gain settings in 5dB steps from 15dB to 70dB.
Gain Trim
High quality Bourns conductive plastic potentiometer can be wired as a full fader or gain trim control, allowing fine adjustment of gain between steps.
Phase Reverse
Inverts the signal phase.
Phantom Switch
Slow-rise phantom power minimizes pops and thumps.
Input Impedance Select
Switch between 1200 ohms and 300 ohms for different microphone impedances
Neutrik Connectors
High quality PC mount connectors eliminate cabling and ease assembly.
Carnhill Transformers
The N72 uses Carnhill input and output transformers. These UK manufactured parts are direct descendants of the original Marinair and St. Ives transformers and are the most convincing replacements available.
