API 512c Pre Amp

API 512c, Destressers, Purple Audio MC77Hey there friends!  The folks here at The Record Shop’s Nashville Recording Studio have been slaving away making some music that should be hitting your ear drums ASAP.  For now though, we are very happy to continue our never-ending series BEHIND THE GEAR!!  So far we’ve talked about a lot of great gear, but today we’re going to talk about a piece of equipment that is universally acclaimed for its sound and versatility.  The one, the only API 512c Pre Amp! 

Did we say universally acclaimed?  You’re darn tootin’ we did.  In a subjective world of personal tastes and preferences it is hard to come by pieces of gear that practically every person likes, but the API 512c is definitely one of those that breaks the mold.  Engineers have been using these puppies since their creation in the 1970’s by Saul Walker.  The 512c was so perfect that, to this day, it’s design has remained the true to Walker’s classic lunchbox design.API 512c Creator Saul Walker  512c’s have been used on countless recordings by artists such as Prince, The White Stripes, Fleetwood Mac, Jack Johnson, Van Halen, and The Rolling Stones.  This mic/line/instrument pre amp sounds great on literally everything. Drums, vocals, guitars…EVERYTHING. 

Now comes the real fun; the API 512c’s wonderful features!

  • Mic preamp with 65dB gain
  • Front- and rear-panel mic input access
  • Line/instrument preamp with 45dB gain
  • Front-panel line/instrument input
  • LED VU meter for monitoring output level
  • 20dB pad switch, applies to mic/line/instrument
  • 48V switchable phantom power
  • Proprietary API fully discrete circuit design
  • Uses the famous API 2520 Op-Amp

 Us Record Shop Nashville natives absolutely love how much punch and clarity you can achieve with the 512c, which is why we installed six of them into our system.  The transparency of the 512c is something that needs to be talked about more.  These pre-amps bring out every harmonic overtone without adding any coloration to what’s being sent through it.  We highly recommend the 512c to anyone and everyone!

Thanks for tuning in for today’s Behind The Gear.  Feel free to check out The Record Shop Nashville’s full gear list here, and come say Hi to us on Twitter @therecordshop!

Behind The Gear at The Record Shop Part 3: Tube Tech CL1B

In part 3 of Behind the Gear at The Record Shop, we take a look at the Tube-Tech CL1B Opto Compressor; a device that has become a studio standard since its release in 1987. The CL1B was developed by Tube-Tech founder, John Peterson. John began his career as a maintenance engineer at the Danish Broadcasting Company. Educated as an electrical engineer, he could usually be found refurbishing gear in his spare time. In the early 80’s his interests turned to tube driven devices such as the Pultec EQ and the Teletronix LA2A. As was the case with many of today’s audio manufactures, John witnessed the growing market for vintage equipment as the quality of modern products was, believed by many, to be declining. He began designing his own renditions of classic equipment, and the rest is history. Tube Tech is now a mainstay in the world of audio, and they continue to produce superior quality tube equipment that has been utilized by everyone from The Rolling Stones to T-Pain.

The design of the CL1B was modeled after the Teletronix LA2A, a classic tube limiter that has been a standard in recording studios since its release in 1965.  John set out to build a device that offered the warm, musical compression of the LA2a Limiter, but with the added features of a compressor. The LA2a has only two controls, Gain and Peak Reduction. The attack and release times are fixed.  The CL1B features a fixed attack and release mode, but also provides additional ratio, threshold, attack, and release knobs. This allows us greater flexibility to achieve the perfect settings for a variety of applications. The Cl1B has another unique setting called Fixed/Manual Mode. This setting has a fixed, fast attack and variable release. You would think that this compressor would come with a two week class to learn how to utilize all of these options. However, the operation is fairly simple and always produces great results.

We lean on this compressor mainly for Vocals and Bass. On vocals we often use the CL1B, in conjunction with an 1176 or Distressor, to add a smooth, warm compression that helps the voice find its space in the track. In the bass world, the CL1B is great at taming the tone, but if you’re going for punch, we lean on some of our other options such as the 1176. From time to time, we will throw a snare or kick through the blue monster to give it some extra warmth as well.

One trick that we have found to be pretty exciting on vocals, is an extreme compression setting that can result in some pretty wicked tube saturation. We start by setting the attack all the way to the left, with a medium release and 10:1 ratio. Next we increase the threshold to hit -10 or so DB of gain reduction; tweaking the ratio and release to taste until the vocal starts to drive. The result is an analog tape like compression that can be perfect for a rocking vocal.

Thanks for dropping by! Check back next week for our next installment of “Behind The Gear at The Record Shop”, where we take a look at a throw back to Abbey Road, the Chandler TG1 Limiter. In the meantime, feel free to drop by our Gear Page for more information on our vast array of equipment.

As always, we love to hear feedback on our articles. If this was helpful, or a complete waste of your time, let us know! We love making new friends as well.

Behind The Gear at The Record Shop Nashville Recording Studio

“Wow! Look at all those knobs.” As an audio engineer that is probably the most common phrase I hear uttered by an artist the first time they step foot in a studio. In an effort to figure out what all these fancy buttons do ;) , we thought it would be fun to introduce a new series on For The Record called “Behind The Gear.” The Record Shop is home to a unique collection of modern and vintage equipment. Our audio arsenal was carefully selected to offer a wide range of sonic colors and textures. Each week we will offer an inside look at a different piece of equipment we use here at The Record Shop. We will take a look at the history of the piece,  outline the various ways it is utilized during a session and share some unique tricks that we use to shape the tone of a recording.

This week, we’ll start the series off by offering some basic information on each category we will be covering: Microphones, Pre-Amps,  Compressors, Equalizers, and Plug-Ins. For those of you familiar with the basic function of these devices, we invite you to join us next week when we take a look at the Empirical Labs Distressor, a studio legend that reigns as one of the most versitle compressor/limiters on the market. For the rest of you fine folks, read on my friends…….

Microphone

If your reading this, I’m sure you don’t need a proper definition of what these things do, but for the sake of covering our bases, we’ll turn to Wikipedia. “A microphone is an acoustic-to-electric transducer that converts sound into an electrical signal.” Sounds simple enough, but what makes our job so fun is that each microphone does this differently and, in turn produces drastically different results. There are three different categories of microphones that are most commonly used in the recording studio: Dynamic, Condenser, and Ribbon. A dynamic microphone is work horse device, capable of reproducing loud sound sources as well as those with a powerful attack (such as guitars, kick drum, and snare drum). A condenser microphone is a more delicate device, designed to react sensitively to its sound source, offering a more defined sound on things such as drum overheads, acoustic instruments, and vocals) A ribbon microphone offers a unique tone due to the natural lack of high end frequency response that the ribbon reproduces. Ribbons have become very popular as a method to achieve a “vintage” vibe on modern, digital recordings. For more detailed information visit Wikipedia’s “Microphone” page….

Pre-Amps

A Pre-Amplifier (pre-amp) is a device that takes a low level signal from a microphone, or instrument, and boosts it to a line level signal that can be recorded. As with microphones, every pre-amp offers its own, unique tonal characteristics. There are two types of pre-amps commonly used in the recording environment: Tube and Solid State. As the name suggests, tube pre-amps utilize tube components to amplify the sound, offering a “warm” tone and a subtle distortion that is preferred in many applications. A solid state pre-amp does not make use of tube components and generally offers a cleaner, more transparent tone. Within these two types of pre-amps are countless brands and models that all have their own sonic flavor. For more detailed information, visit Wikioedia’s “Pre-Amplifier” page….

Compressor

A compressor is an audio device that effects the range between the loudest and quietest parts of a sound source (known as dynamic range) A compressor accomplishes this by lowering the volume of the sound source when it passes above the volume threshold that is set by the user. The amount of compression, and the reaction time of the device, is set by the ratio, attack, and release knobs. Just like pre-amps, compressors are also built with either solid state or tube components. Compressors can be used for a variety of applications, from subtly taming dynamics,  to extreme “pumping” that can create intriguing rhythmic effects. For more detailed information, visit Wikipedia’s “Audio Compressor” page…

Equalizer

An equalizer adjusts the balance between frequencies in an audio signal. It allows us the ability to “shape” the frequency range of a sound in order to enhance its qualities, fit it into a mix, etc. There are two main types of EQ’s used in the studio environment: Parametric and Graphic. A Parametric EQ offers a variable frequency selection on multiple frequency “bands” (ranges) and a variable “Q” (range of effected frequency). This allows us the flexibility to hone on the desired frequency and effect it accordingly. Graphic EQ’s have fixed frequency and q selection, often based on frequency “octaves” to offer a natural, musical response. For more detailed information, visit Wikipedia’s “Equalization” page…

Plug-In’s

Plug In’s are used in digital recording to emulate the function of analog equipment. While, it can be argued that software can never take the place audio moving through actual components (and I agree!) software plug-ins have continued to grow in their sonic offering and can be very useful in the modern recording environment in many situations. There are endless options when it comes to plug-ins. The market is flooded with new, innovative tools for manipulating audio. A recent development in plug in technology is what is referred to as “emulation plug-ins” These software devices are built off of algorithms developed through the testing of actual analog gear. Through this process, developers have been able to create plug-ins that embrace the tonal qualities of a specific type of gear. This is a very exciting technology that we have found very useful in Universal Audio’s, UAD Plugs. You can learn more about Plug-ins by visiting this interesting article at Delicious Audio…

Well, now you are ready to venture “Behind The Gear” at The Record Shop. Check back next week for our first installment, highlighting the Emperical Labs’ Distressor. In the meantime, feel free to drop by our Gear Page for more information on our vast array of equipment.
