ACL – System 2
System 2 is a modular instrument built entirely from ACL components. The search for a microcomputer in this system would be in vain because all modules are analog and for the most part discrete.
The System 2 is a powerful sound shaping workshop that will make anyone with a preference for discrete audio circuitry sit up and take notice.
System 2 consists of the following modules:

Variable Sync VCO: Analog oscillator with voluminous sound and almost magical FM qualities.
Multifunction Discrete VCO The new monster VCO by ACL with an excessively equipped sub-oscillator.
Discrete Core Ladder VCF Refined low pass – ACL’s discrete transistor loader filter is characterized by its pithy sound, low noise and all kinds of technical refinements.
2x Oktave: Specialist for processing and routing pitch CV signals.
Gate Mix: Four-channel mixer with voltage-controllable mute levels.
2x Multi II (buffered)
Envelope X3: A snappy triple ADSR envelope.
2x QLFO: Tonally playable quadrature LFO with sine wave. – Perfect for FM experiments.
2x VC Dual Amp: The ACL VC Dual Amp is a high-quality dual linear VCA with mixing function. The module contains two fully discrete voltage controllable amplifiers with linear characteristics.
Audio Interface: Converts modular signals to studio level. – And vice versa. The sound quality is excellent.

The whole thing comes in a metal case with oak side panels. A KAZU power supply is also included. – However, not as a module, but discreetly installed inside. This leaves four partial units for personal additions. The KAZU power supply is characterized by minimal interference and voltage peaks. The same applies to the built-in EVE 1 bus board. The result: extremely clear high-end sound.
