The Analogue Solutions Colossus Quartz AS250-MOD is a remarkable VCA, Envelope and LFO  module that exemplifies the prestigious Colossus range. It is designed as an add-on synth expander, allowing for the gradual construction of a complete Colossus System while offering affordability and exceptional versatility.

The Analogue Solutions Colossus Quartz AS250-Mod has four Voltage Controlled Amplifiers (VCAs), allowing for precise control over audio levels. Additionally, the synthesiser incorporates four Envelope Generators, enabling sound shaping through dynamic modulation.

The AS250-Mod also has two Low-Frequency Oscillators (LFOs) to enhance its versatility. These LFOs provide flexible modulation options, allowing users to add subtle or dramatic variations to their sounds.

A notable feature of the AS250-Mod is its LCD Dual Channel Oscilloscope. This visual display provides real-time feedback on the generated waveforms, aiding in sound design and analysis. In addition, the synthesiser offers an upgrade path to a single-channel Cathode Ray Tube (CRT) oscilloscope for those seeking an alternative display option.

In addition to its extensive sound modulation capabilities, the AS250-Mod features a Touch Keyboard/Sequencer. This integrated input system allows for intuitive note input and sequencing, facilitating the creation of intricate melodies and rhythmic patterns.

Colossus Quartz embraces the pure essence of analogue synthesis, incorporating 100% analogue voice and modulation circuits. While the sequencer control includes digital elements in line with classic analogue sequencers, MIDI and USB connectivity are intentionally omitted to maintain an authentic analogue experience true to the origins of synthesis.

Meticulously crafted to perfection, Colossus Quartz embodies the true essence of a pure synthesiser. Its robust metal chassis, enveloped in wood, reflects the attention to detail and commitment to quality. It represents a rare synthesis innovation that emerges once in a decade or even a generation and is an instrument of exceptional craftsmanship.

Experience the unrivalled power and sonic capabilities of the Analogue Solutions Colossus Quartz AS250-MOD, specifically tailored to meet the demands of professionals. Elevate your music to new heights with this remarkable module, offering an unparalleled synthesis experience that pushes the boundaries of sonic exploration.
