Dual VC Delay

Description

The Dual VC Delay consists of 2 equal, independent delays A and B, each with its own feedback loop.

Each contains a 6dB HP and a 6dB LP filter (not VC), but the internal feedback loop can be opened by patching a cable into the “IN FB” – jacks to route other signal-processing modules into the feedback-loop. Please note that there is no “Dry-Signal” path. By designing the module, AQA thought, it would be mostly used in combination with other modules to achieve some echoes and reverberated ambience, one could put one delay in the feedback-path of another delay for example – there are many different routing configurations, achieving strange modulated reverberated space by combining several Dual VC Delay-modules in various manner.

Due to its vast flexibility, the module offers loads of possibilities for hours long sessions of mangling signals, pitch modulation and the generation of ‘phantastic’ ethereal outer galactic spaces. Used in parallel/stereo-mode, it generates voltage controlled modulated spatial effects with its own special character. The sound of the Princeton PT2399 delay chip often reminds for BBD-circuits which principle in fact shares similarities with the function of the PT2399 chip. Because the audio – and CV – inputs are normalized in the scheme of A=>B, the module is following your needs for many different patching situations easily. The sonic possibilities of using several modules together can be mind blowing, especially when the almost endless possibilities of different feedback-routing are explored.

Features

• Delays can be routed in parallel or serial configuration (A => B or A II B)
• internal feedback with a 6dB HP and LP filter in series for each delay, feedback signals are attenuverted
• using normalized feedback in and out jacks, the feedback loops can be opened to insert other stuff
• feedback can be switched between parallel and cross routing between A and B
• Audio input attenuators for each Delay
• each delay time can be independently controlled by knob
• each delay time can be independently modulated by an attenuverted external control voltage
• each delay time can be independently modulated by an attenuverted external control voltage
• Normalized audio signal Inputs
• Outputs for the delayed signals
• Outputs for the delayed signal and HP+LP filtered delayed signal (for feedback use)
• Normalized feedback-signal Inputs
