Designed for situations where less track counts are enough, but added flexibility is needed. Its 4 auxiliary sends allows cue mixes, analog reverb and fx sends, parallel compression, etc, all in the analog domain. It also has balanced points on every input and output for outboard gear integration. 4 transformers and a class A output stage ensures a correct vintage sound.

The MixDream XP is a cascadable, 16-in-2 analog summing device. Exclusively built with discrete Class-A technology based on a 60V rail guarantees an extremely high slew rate, a low noise level of -97dBu (A-weighted, all channels active) and a dynamic level of over 125dB. Thus the MixDream XP easily exceeds the level of performance of the best analog consoles.

The Tube Vitalizer represents the top-of-the-line, patented audio enhancer that applies psychoacoustic and audiometric principles to make your music more stimulating, vocals more intelligible, loudness more intense, and the whole soundscape wider and more detailed. The interactive parameters make it possible to alter the sound in a musical and effective way.

Introducing The Warm Audio BUS-COMP The Warm Audio BUS-COMP is an all-analog, 2 channel, stereo VCA bus compressor based on classic circuitry that has provided silky smooth tone for decades. Stereo VCA bus compressors are masterful at controlling dynamics on many sources, but they have become widely known for their magic touch on stereo mixes. The BUS-COMP will perform well on stereo mixes, drum

Pultec Style Tube Equalizer The EQP-WA is a re-creation of the most renowned tube Equalizer in studio history, the "Pultec EQP-1A". Not only does the look and feel of the EQP-WA match the classic Pultec units, but the sonic quality has been carefully considered by using top-end components such as CineMag transformers and premium tubes. This fully discrete Tube EQ can pull euphoric sonics from any

Analog Tone Though digital technology and software have made great strides in recent years; we still believe that nothing compares to the level of articulation, depth, realism, and responsiveness of a well-built piece of analog gear. When you hear the bottom-end presence and top-end detail of quality analog gear, the difference is astounding. The cost of most boutique analog equipment is financia

A Single Channel '73 For The Rest Of Us If there’s one style of preamp that professional engineers would unanimously agree has defined the tone of pop/rock records for decades, it would most definitely be the venerable '73-style of mic pre. '73-style preamps have been massively used in recording and live applications for many years and are still considered to be the “Holy Grail”

Classic Style The WA76 Discrete Compressor is a modern reproduction of the Classic '76 Revision D. The WA76 has a fully discrete signal path and uses the original Reichenbach Engineering's (now CineMag) transformer design. The classic '76 was a major breakthrough in limiter technology, and used on hundreds of hit records since its inception. Engineers have craved the ultra-fast attack time and tr
