Threetom Modular - Doppio

The Threetom Modular Doppio is a compact stereo amplifier, drive, and soft limiter module. Doppio helps complex and dynamic stereo sounds to find their place in a modular synthesizer context, where signals are hot, and headroom is extremely limited. Doppio does this by implementing a compact, yet flexible, soft-knee limiter. The limiter is specifically designed for eurorack levels and avoids the need for unnecessary make-up gain, resulting in a lower noise floor.

Doppio offers three different gain settings (x1, x5, x21), and three different ratios (linear, drive, and limit). In addition to this Doppio has gain and volume knobs for more precise control. Different combinations of these settings cater to applications like saturating complex stereo signals without turning them into mush, end-of-chain limiting, and boosting line level signals to eurorack level, while still retaining enough oomph to also saturate them nicely. Finding the right settings is made easy by DOPPIO’s unique coffee-bean-shaped indicator lights.

Even though Doppio’s architecture is stereo, that doesn’t mean it has no uses on mono signals: Either process two mono signals with identical settings, or chain the two channels to form a two-stage high-gain mono drive. Finally, it’s important to note that Doppio is DC-coupled and can also be used to process CV signals.

In summary: Doppio is to your signals what a double espresso is to you – it makes you bigger and bolder – and you know you’re hooked when the withdrawal symptoms kick in.

Features:
• Three different maximum levels of gain: x1 (0dB), x5 (+14dB) and x21 (+26dB)
• Three different soft-clipping modes: Drive mode, Off / linear mode and Limit mode
• Caffeine knob for fine control over the gain applied to the inputs
• Volume control for post-gain attenuation
• Coffee-bean-shaped indicator lights make finding the desired settings easy
• Reverse power protection
• 4-layer PCB design with completely separate of audio supply rails and ground
