Seventh Circle Audio CH01, (2) N72 Neve Clone & T15 Microphone Preamp, Mic Pre

Up for sale is my Seventh Circle Audio CH01 modular rack/mainframe/power supply with (2) N72 modules and (1) T15 module. These are in great working condition and, if you're looking, I probably don't need to tell you about how great they sound.

The N72s sound fantastic and my favorite application was electric guitar; big thick electric guitars. The n72s have real Carnhill transformers for an authentic Neve sound. The T15 is also a very good preamp with a more neutral character. Better than an average interface preamp and just as good as what is in my RME interface (mid-grade professional). You have 5 slots open for other modules.

It works perfectly so unless something crazy happens, there will be no reason to return it. Thank you for your understanding. The 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.

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. A 12 position Grayhill switch provides accurate and repeatable gain settings in 5dB steps from 15dB to 70dB.

High quality Bourns conductive plastic potentiometer can be wired as a full fader or gain trim control, allowing fine adjustment of gain between steps. Slow-rise phantom power minimizes pops and thumps. High quality PC mount connectors eliminate cabling and ease assembly. 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. On-board voltage regulator can accommodate power supplies from +27DC to +35VDC.

Local regulation also keeps inter-channel crosstalk extremely low when multiple preamps share the same power supply. The SCA T15 is a transformerless microphone preamplifier designed around the excellent THAT Corporation 1512 and 1646 ICs. These state-of-the-art chips enable the performance of the T15 to approach that of sophisticated discrete and hybrid designs (such as the C84) while using far fewer components.

While it does not have the same headroom and output drive capability as the C84, the T15 has similar noise and distortion specifications and excels in the same applications. Unlike the C84, the T15 has a small number of components, requires no adjustment or trimming, and is very easy to assemble. The T15 can provide 70dB of gain, more than enough gain for most applications, especially with modern high-output condenser microphones.

Since 5dB is often too big a gain step, the T15 also has a gain trim control which provides up to 6dB of cut at any gain setting. This allows very fine adjustment of gain between steps. This control can also be configured as a full fader. Similar to the C84, the T15 employs two DC servo circuits.

On-board voltage regulators can accommodate power supplies from +/-15VDC up to +/-35VDC, allowing the use of op-amps with +/-24VDC requirements.
