Chandler Limited REDD 47 - Tube PreAmp
Chandler Limited’s REDD.47 microphone pre-amplifier is a recreation of the original valve line amplifiers used in Abbey Road Studios’ heralded and rare EMI REDD.51 recording consoles circa 1959-1968.

Designed as a central component to the EMI REDD.51 recording console, the original REDD.47 line amplifier was used to amplify virtually every stage of the audio path (mic inputs, line inputs, echo sends and monitors).
The REDD.47 lent its unmistakably punchy, aggressive character to music recorded at Abbey Road Studios between 1964 and 1968, including many tracks by The Beatles.

The Chandler Limited REDD.47 pre-amp offers many additional benefits to the original design including increased gain, allowing a range of tonal options from pristine clean sound to classic rich, saturated tone with up to 2% harmonic distortion before clipping. The Chandler Limited REDD.47 pre-amp easily reproduces the distortions heard on The Beatles’ ‘Revolution.’

Lindell Audio 18Xs MKII is a one channel transformer coupled Microphone Preamplifier, DI, Line Amplifier and Passive Pultec Equalizer. It’s an Class A design based upon our Hybrid amplifiers. (It can be upgraded with our Vintage OPA)

The Equalizer is our take on the magical classic Pultec design. It’s got 15db boost of the creamiest high end you’ve ever heard and the most punchy low end heard the 21th Century.

We have also incorporated our famous ”Mix Knob” from the 17X compressor. This means that you can parallel equalize your line input. This gives you more flexibility and a way of creating new tones….

Mother Kamaya (meaning "precious one" in Hawaiian) - 500 Series Preamplifier
Kamaya is a Class A circuit microphone preamp inspired by vintage British classic console preamps. It can deliver up to 62 dB of gain to your microphones, but more importantly, it gonna breathe life into the sound, adding a new dimension and unique character that is hard to compare with other preamps in the market.

Kamaya is the result of months of research, experimentation, and testing. The input transformer is inspired by  the legendary Marinair 10468 (named here as 10568, logically, right?), but with a higher ratio and tailored to our taste.It truly shapes the sound in a such a way, that Kamaya becomes vibrant right from the input.

Chandler Limited TG2 - Two Channel Mic Preamp/DI
The Chandler Limited TG2 is a recreation of the rare EMI TG12428 pre amp used in EMI/Abbey Road recording and mastering consoles used in the late 60's and early 70's. The sound was used on many famous recordings done at Abbey Road including The Beatles "Abbey Road" and Pink Floyd "Dark Side of the Moon." The amplifiers were also used in many EMI circuits of the time. Our version was remade from original design notes and circuit board drawings, provided by Abbey Road and EMI to ensure extreme authenticity!

This Mic Pre features the same discrete transformer balanced amplifiers as the TG series limiter and offers a creamy, smooth tone with a surprisingly open, clear top end (dare we say nicer than Neve....) The sound, as explained by many users, has the Neve "warmth" and punch, but with a "nicer" expanded top end. In fact the unit does have a small rise in its top end frequency response and some warmth inducing distortion which contribute to its sound.

McAudiolab 8P -  Class-A solid-state 8 Channel Preamp and DI
The goal was to build a new mic preamplifier that exhibited the qualities of Class A range. Packing eight preamps into one chassis with one power supply. You won’t find any cut corners here, each channel uses Macaudiolab's super well-sounding 816 Class A discrete Op-Amp, as gain stage. The mic inputs benefits from the sound of the legendary Lundahl transformer which exhibits an incredible frequency response whilst adding a subtle amount of harmonic distortion. The excellent sound produced by this combination has been well proven in McAudiolab's 500 Series products. No matter what you feed it with. Another advantage of the transformer coupled input, is noise – or lack of it. Transients are preserved and the bottom-end sounds full, making the 8P the perfect choice for all music genres.

Purple Audio PANTS is a four op-amp, differential mic preamp. Designed to work in standard “500″ racks.

The Pants uses a unique dual-bobbin input transformer from Cinemag unlike any other. The smooth Gain control helps you dial in the sound you want. If the output level is too high, you can ride the level down with the separate Level control. Pressing the “High” switch changes the feedback network to provide an insane 78dB of clean gain, a great match for very low output mics.

With different Gain, High mode switch, and Level settings the Pants can produce many different tones with the same amount of output level. The front panel DI goes through a FET buffer into the input transformer, adding an extra dimension to the sound of the preamp.

Buzz Audio QSP-20 - 4 channel Mic Pre
If you are looking for a versatile but cost effective outboard mic preamp for your project studio, then you've found it!

Teknosign GAIN is a microphone preamplifier with digital controls of great design and superb sound. It has 2 channels and on each of them you can control the gain (up to 60 dB) and attenuation (0 – 63 dB), each level can be read on top of each knob on a 2 digits 7 segments display. In addition, 4 buttons per channel provide: 20dB attenuation, Phantom Power 48V, Phase Reverse and selection of either Microphone or Instrument. It has a custom transformer and a custom op-amp on each channel plus a general toroidal transformer for power supply. The design is specular giving you an immediate feeling with the machine and its 2 channels.

BUZZ AUDIO MA-2.2BTX - Full Class A Microphone pre-amplifier with Lundahl LL1517 output transformers
A truly magical sounding microphone preamplifier that proves "clean does not need to sound clinical", now revamped with an updated user interface.

Functions are now controlled with illuminated push button switches with "clickless" operation, no more thumps on the output.
The gain pot has been replaced with a calibrated 24 position Elma switch for accurate stereo matching between channels. Buzz Audio has added a useful 19 segment peak output level meter. But, the original audio and power supply design of the MA-2.2 has been retained.

The MA-2.2BTX is supplied with high spec Lundahl LL1517 output transformers. When the transformers are fitted, the direct unbalanced output is still available on the rear panel via a 1/4" jack socket. When fitted, the transformer add a bit more warmth to the sound. (We can also offer the Lundahl amorphous core LL1684 transformer to special order).

GC Audio GY 4.5 is a genuine tube preamplifier: Coming with two ECC82 running on high voltage, no solidstate component in the signal path, input/output balanced by high-end Lundahl transformers. The goal with this design is to achieve everything from a completely clean to a possibly very colorful sound imprint. All under the total control of the user. The most important aspect of this circuit is its very slow transition to overload - it has a sweet spot that seems to last for ages.

We recommend it e.g. for vocals, where by raising gain and lowering output volume, you can get a nice dense analog saturation without overloading your converters. This cartridge is a real creative tool.

The proprietary Inherit format keeps the sensitive part of the electronic design in a one-piece machined cartridge that acts as a Faraday cage to offer optimal electromagnetic shielding performance.

Chandler Limited Little Devil Preamp
The Little Devil Pre Amp might be the best piece of Chandler gear yet! Several things make it so special.

The class A gain stage sounds like no other design we've done. It's big, yet open and full of life. Just about any parameter of the sound is changeable including the ability to change both the Feedback and Bias of the amplifier. The Feedback control increases harmonics thousands of times over the range of the control. The nature of clipping and distortion also changes and ranges from soft Class A clipping to super soft gushy tube type. The sounds range from a very colored and "overbiased" tone to a gently colored and "in your face" tone.

The GC Audio RE 98 cartridge is a reissue of famous British mixing console preamplifier from the 90s, the Amek 9098 designed by Rupert Neve / Graham Langley. Many improvements have been made to achieve better results:

• Ultra low noise SSM2212 paired transistors
• Ultra low noise Operational amplifier: OPA1612
• Great care taken to the PCB Routing
• Lundhal 1585 balancing

We recommend it for audio engineers looking for very quiet and clean recording with a subtle coloration on the top end.

BUZZ AUDIO MA-2.2B - Full Class A Microphone pre-amplifier
A truly magical sounding microphone preamplifier that proves "clean does not need to sound clinical", now revamped with an updated user interface.

Functions are now controlled with illuminated push button switches with "clickless" operation, no more thumps on the output.
The gain pot has been replaced with a calibrated 24 position Elma switch for accurate stereo matching between channels. Buzz Audio has added a useful 19 segment peak output level meter. But, the original audio and power supply design of the MA-2.2 has been retained.

The Germ 500 MKII is an updated version of our original Germ 500. This unit has an improved faceplate layout and nicer look. It uses classic germanium transistors in all class A, transformer balanced circuits. We have also updated the power on the MKII so there no known power-up issues with current lunchboxes and rack systems.

GC Audio Inherit Rack + Graham Langley Cartridge co-founder of Amek and designer of many large format mixing consoles (Amek Mozart, Rembrandt, Angela, ... etc.).

A premium differential preamp composed of paired transistors and constant current sources. The unit is digitally controlled to isolate the analog signal path in the metallic  cartridge (and therefore separated from the radiation of the linear PSU). Common mode rejection and output balancing are manually calibrated to achieve optimized values. The resistive ratios are composed of low value in order to obtain an optimal EIN.

This preamp is perfect for user needing uncompromising sound pickup with a transparent and powerful result.

VSP-2 Dual Mic Preamp 1976
The VSP-2 is VERTIGO SOUNDs 3rd BIG IMPACT DESIGN and is setting a new benchmark in microphone amplification.

The heart of this unit is Vertigo Sound 100% discrete Twin Op Amp circuit called the OPA (operational amplifier) 1976.

These "in house" engineered & built discrete amplifier stage is combined with Jensens world famous JT-16 Mic transformers and provide a smooth warm and defined sound from the lowest bass to the very top end of the sonic spectrum.The JT-16 transformer can handle very high input levels and provides a very linear phase behaviour because of low capacitance problems due to it`s low ratio of 1:2. Further the low ratio of the transformer forces the discrete OP Amp to provide most of the amplification in the VSP-2. This " full throttle","pedal to the floor" circuitry enables a unique, rich, full and characterful sound.
