B12A Quad – Four Channel Mic Pre

Program Equalizer and Microphone Preamplifier Eighteen’s preamplifier circuit isn’t just another clone, but an original design built to pay proper tribute to some of the most classic designs ever made. The Eighteen starts with a Cinemag input transformer, but that’s far from where the magic stops. In order to get the absolute perfect sound we were looking to achieve with Eighteen meant a bit more work under the hood. This is where our new BLA1831 custom, discrete op-amp comes into play. Through an extensive period of component matching, we were able to create a custom op-amp that matched the vibe we were aiming for, while still matching a noise floor that is akin to modern equipment. The preamplifier also features polarity inverse, 48V phantom power, an 80Hz high-pass filter, and a 10kHz low-pass filter. .embed-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } .embed-container iframe, .embed-container object, .embed-container embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; } .embed-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } .embed-container iframe, .embed-container object, .embed-container embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }

The Auteur Quad is the four channel microphone preamplifier version rack mount of our ever popular Auteur MK2 mic pre. The Auteur has become a studio staple over the last decade and is know for its fast, transparent IC based front end while also providing a fat, colorful back end via edcor transformers. This mixture of vintage and modern design approaches has led the Auteur to be known as the “Swiss army knife of preamps” that sounds great on everything. It especially shines on sources that require detail but also benefit from some thickness such as drums or vocals. Some of the major additions to the Quad over the 2 channel half rack unit would be the all new meters on all four channels as well as borrowing the loved DI circuit from our 500 series Auteur on the first 2 channels. This feature set as well as channel count gives you one of the most affordable preamps in the world at an unbelievable price
