Legendary 2500 Series Ring Modulator and VCA Module for Eurorack The MODAMP MODULE 1005 is a feature rich ring modulator to create metallic and bell-like sounds as well as many other modulation effects, modulation can be applied to any signals such as a signal from VCO’s or LFO’s via the INA and IN B jacks and is fed out via the VCA output. The 1005 features INA and INB attenuators, an UNMOD gain control lets you set the gain when in UNMOD mode, a VCA with gain control and a choice of exponential or linear response, Ratio and tune controls allow you to control and balance the frequency of 2 external VCO’s for convenience. The illuminated UNMOD and MOD switches disable or enable modulation effects Features Ring modulation module Dual inputs with independent attentuators Unmod and Amplifier Gain controls Exponential or Linear amplifier response modes CV, Gate, mod, and Unmod inputs
