Description

At the heart of the ISA range is the microphone preamplifier with its Lundahl input transformer – essentially the same circuit, based on the original ISA110, that has been used for 30 years in successive Focusrite designs. The input transformer imparts a special character to the sound that can’t be truly emulated in any other way: inseparable from the microphone itself, the transformer input stage is ideal for use with classic microphones. But this mic pre has a twist the original didn’t have, which makes it far more versatile: four carefully-selected impedances allow you to match microphone to input in different ways. Bring out the character of a classic mic or emphasise a special feature, or go for a totally transparent, modern sound – it’s up to you.Whether you’re an artist, engineer or producer, you’ll appreciate the versatility of the ISA One, with its front-panel DI input. The DI includes low/high impedance switching and an amplifier output, and its own feed to the optional A/D converter and separate rear-panel XLR output.

ISA series transformer-based preamplifier
Encased in a rugged and portable chassis, ISA One offers the classic Focusrite microphone preamplifier at its lowest cost to date.

Flexible independent DI channel
ISA One is ideal for both engineers and demanding performers alike, featuring independent gain control, an output for routing to an amp, an independent XLR output on the rear and routing to the optional A-D converter.

Switchable impedance
Choose one of four carefully selected input impedances, including the original ISA110 setting, to suit any microphone.

Headphone output with volume control
ISA One can feed either a sum of the two input to the headphones output, or an external stereo cue mix (such as a stereo feed from an interface) via two TRS jack inputs on the rear of the unit.

Dedicated insert point
Allows you to place extra processing between the preamplifier or DI and the optional converter, such as an EQ or compressor.

Optional stereo 192kHz A-D converter
You can chose to upgrade your unit with an optional digital card that delivers the best A-D performance in its class (dynamic range of 118dB). Alternatively, the ISA One Digital comes with the A-D converter as standard.

Lundahl LL1538 Input Transformer
The original mic transformer used in the original Red modules helps to provide the unique sound and performance of this groundbreaking design.

Backlit VU meter with variable calibration
ISA One has a moving coil VU meter with variable calibration to suit analogue and digital recording media, alongside two six-LED peak meters; inputs can be metered either pre- or post-insert.

The product that started it all for Empirical Labs. Born of founder Dave Derr’s love of classic compressors like the 1176, LA-2A and Gain Brain (among others), the Distressor incorporates his favorite sonic characteristics of these, along with other unique and interesting features that have made it a staple for audio engineers all over the world. With over 28,000 units in the field, it’s safe to say that the Distressor is one of the best selling high end compressors of all time… if not THE best selling. A prominent recording engineer recently wagered that there probably was not a top 40 record made in the last five years that didn’t have at least one Distressor on it.
Besides providing a wide range of control and a unique feature set, the Distressor offers a warm, vintage sound by using a custom designed gain control circuit. This “warmth” or “vintage sound” has become a major issue in the last few decades, as the super clear and linear digital technology does next to nothing to soften “harsh” sounds, nor emphasize the bass frequencies in music sources. Conversely, older analog tape, vinyl records and tube equipment could not be prevented from coloring the sound, often to the frustration of recording engineers. However, many people now realize that this coloring can be extremely pleasant and musical. Digital technology is often referred to as “cold” and “brittle” among other terms (although we prefer “unforgiving”).
Unique Compression Curves All eight of the Distressor’s curves are unique and distinctive, from the 1:1 mode that simply warms up signal with low order harmonics without intentional compression, to the “Nuke” setting – a brick wall limiting curve that shines on live drum room mics. Each curve has its own personality and several actually use different circuitry, and are effectively different compressors. Most exceptional is the 10:1 “Opto” ratio which uses separate detector circuitry to emulate the oldest (and valued) “light controlled” devices, such as the LA-2A.
Distortion (Color) Modes Another large part of the Distressor’s personality and power derive from three modes that color the signal, even without compression. These extended audio modes were designed to allow emulation of some very old and expensive vintage compressors & limiters, and let the Distressor deliver a classic “knee” sound all its own by providing user programmable, warm harmonic distortion. In addition to the basic distortion mode, Distort 2 emphasizes tube-like 2nd order harmonics, while in Distort 3 setting the distortion becomes dominated by 3rd harmonics more closely resembling tape. Two HP filters – one in the audio path, one in the detector path – are also available to help with low frequencies that can cause pumping and breathing.

There’s no doubt that when it comes to power, musicians have it bad. Whether it’s modern modeling amplifiers, or vintage synthesizers, bad power is gonna be heard throughout your signal. And it’s everywhere — in homes, on stages, and especially in many rehearsal rooms. Black Lion Audio has been trusted for years for modifying the best gear and making it even better, and that’s what it took to create the PG-P: taking industry-standard designs, and improving them to the point of peak performance. After creating an entire lineup of industry-best power conditioners, Black Lion Audio felt it was time to give the world proper portable power. The PG-P might look like a run-of-the-mill surge protector, but in reality it’s a studio-class power conditioner — PG-P doesn’t just provide more noise filtering than other portable conditioners, it provides the same noise filtering found in the majority of the world’s rack-mount power conditioners! Your gear deserves the best power, and Black Lion Audio took great care in making sure the PG-P delivers just that — thanks to it’s PG-P Filtering Technology. The PG-P is built using premium Panasonic capacitors, due to their superior execution in eliminating high frequency noise that robs equipment of its peak performance. In testing, this has provided an average of 3x the noise filtering of other portable power conditioners at the same price point. Six wall-wart spaced outlets provide studio-grade power on the go; perfect for any musician’s rig!

Radial X-Amp Active Reamper
  • Active Reamp® with two outputs
  • 100% discrete class-A signal path
  • Transformer isolated to eliminate noise
  • Variable 'set & forget' level control
The Radial X-Amp is an active Reamper™ that allows the engineer to play a pre-recorded track back through guitar amplifiers and pedals. This opens the door to explore new musical sounds and spur on the creative process so that your recording stands out. Using the X-Amp is easy: start by recording a dry track using a high quality direct box like the Radial J48. Send the new track from your recorder via the X-Amp to your guitar amps, effect pedals or combinations thereof. Once the basic track has been recorded, replacing or adding tracks can be done well after the session player has gone home. This eliminates tiresome repetition and assures a fresh vibrant performance on the final recording. Furthermore, by driving two amps at the same time, new sounds and textures can be created while allowing you to make artistic decisions as the recording progresses. Following the critically acclaimed Radial JD7 Injector, the X-Amp employs a unique class-A circuit design that has been optimized for use with guitars. Features include balanced line level input with LED peak indicator and level control, class-A circuit topology for optimal reach and frequency response, a transformer isolated output to eliminate hum and buzz caused by ground loops, a 180º polarity reverse switch to bring both amps into phase, and a dual ground lift switch for noise-free operation. As with all Radial products, the X-Amp is built like a tank to provide years of trouble-free performance. An internal I-beam skeleton provides maximum protection against external stress which could cause solder points to fail. This is supplemented with an innovative bookend design that creates a protective zone around the switches, potentiometer and connectors. A full bottom no-slip pad performs double duty by keeping the X-Amp from sliding around when placed on a vibrating amplifier while also providing electrical and mechanical isolation. Reamping works equally well on bass, keyboards, drums and voice. Once you start Reamping, you will never record any other way. The Radial X-Amp… the active Reamp® for professional recording engineers.
The vintage EQ tones you know & love. The 551 is the only equalizer for the 500 Series actually designed by Rupert Neve. Featuring 3 bands of EQ inspired by Mr. Neve’s most prized vintage designs, along with custom-wound inductors, transformers and class-A gain blocks, the 551 brings the thick, powerful lows and sweet highs of Rupert’s classics to the 500-Series format. The “Best-Of” EQ The 551’s 3-band, custom-tapped inductor EQ was inspired by our favorite elements of Rupert’s vintage EQ designs. The low frequency band is designed to produce a creamy, resonant bass response similar to a vintage 1064 – but unlike the vintage modules, the LF band on the 551 can be used as either a shelf or a peak filter, adding punch, dimension, and control to your low end. The midrange band is based on that of the 1073, ideal for sweetening vocals and instruments while bringing them forward in a mix, and its proportional “Q” response makes it well-suited for minimizing problematic frequencies. The high frequency band is a hybrid vintage / modern design, blending inductor circuitry with capacitor-based topologies to achieve vintage tones with enhanced control. The High Pass filter is a 12dB/octave design with a fixed 80Hz frequency, and can be used in tandem with the low frequency EQ to add low-end presence without clouding the source material. As with Rupert’s most prized classic designs, each EQ section uses low-feedback, class-A discrete electronics to prevent low-level artifacts and harshness from detracting from the tonal shaping. However, this new circuit is a decidedly modern design with updated techniques and components that were simply not available 50 years ago, and is definitely not a “clone”. What Are Inductors? Inductors are wires wound around a coil that provide a form of frequency-dependant resistance. When they saturate, they bring out beautifully musical harmonics that give your tracks the smooth, polished sound that has made Rupert’s consoles and equipment so desirable for over fifty years. This is what makes them different from capacitor-based EQ designs, which do a great job at surgical equalization. But inductors provide the tone. While it is certainly possible to create a functioning EQ using off-the-shelf inductors, we choose to use our own custom inductors for the 551. This attention to detail in controlling variables such as the winding and core materials in relation to the surrounding circuitry allows the 551 to capture the vitality and personality of Rupert’s classic designs.
