With the "initial level" controlyou can open the VCA manually what is handy if the modulation signal is bipolar: e.g when doing a tremolo with a sine wave LFO. Tow CV inputs with attenuators are available: The linear one is better when you want to control CV signals or if the modulation signal is a slow LFO. The exponential input is better for punchy, fast modulation, e.g. by an envelope and is also bertter suied when you want to control audio signals.
Two signal inputs make an mixer module obsolete.
The Dual Bus version of the RS-180 features two power connectors, meaning it can be directly connected to either an Analog Systems or a Doepfer modular system. – Adapters are no longer necessary.
Because of the different position of the mounting holes there will be a gap of 0.5HP (= 2.5 mm) when mounting an Analogue Systems module next to a Eurorack module. Take this into consideration when planning your system. Gaps can be covered with 1.5HP wide blank panels by Doepfer.
