YELLOW IN is a high-voltage Class-A instrument preamplifier designed to be directly connected without using an external preamp, pedal or guitar amp. It can accommodate virtually any musical instrument pickup, or a passive electronic instrument.

ARTHUR FORMAT 48 is a modular mixer that can be designed and built by the user. Offering an unparalleled degree of flexibility, this mixer has already become a firm favorite with a number of leading artists and engineers.

A range of different modules can be combined in virtually any order and quantity in just a few minutes. These contain all the standard features you would expect to find on other mixer channel strips, as well as more innovative functions for enhancing workflow and ensuring best possible sound quality.

ARTHUR’s electronic design features a complete absence of Negative Feedback from input to output, resulting in ultra-fast response and natural attack. Circuits are built using single, discrete Class-A electronic components and pure high-voltage DC amps (with no capacitors in the signal path), offering 30dB headroom and low noise, as well as unparalleled stability, warmth and transparency.

Once the mixer is built, the unit sequence can still be customized and further modules added as required.
