Key Features
Product Ref: 94807
The Z2040 Voltage Controlled Filter is based on the famous SSM2040 filter chip. It is an enhanced 4-pole VCF with a discrete circuit design with significantly extended capabilities compared to the vintage sound of the chip it is based on. With Tiptop Audio's huge, lush signature sound, the Z2040 delivers thick low-end with rich leads and astounding dynamics. It features inputs to allow modulation with audio frequencies, delivering colourful and interesting tones and textures. The circuit is non-linear, and with the Resonance feedback maximised, the Z2040 can be converted into a pure sine-core voltage-controlled oscillator, making it ideal for creating a wide array of timbres.
The Z2040 is equipped with an audio VCA that can be configured at either the input or the output of the filter (adjustable using headers and jumpers on the unit's PCB). The gain knob on the front panel functions completely independent of the VCA, and only sets the input gain regardless of the position of the VCA (VCA on input or output). When the VCA is configured to the input, then the audio from the VCA and from the gain knob are mixed together. When configured at the output, the gain knob only affects the input. This allows you to maintain control of the input gain no matter what the VCA is configured to.
The Tiptop Audio Z2040 4-Pole Low Pass VCF features three different positions for the gain knob with differing behaviour:
The Z2040 features an input labeled FM. The module adds a unique feature, providing the ability to modulate the magnitude of the FM signal by another signal. This is achieved by placing a VCA on the FM line. This simple yet effective structure provides a variety of modulation tricks. The most common use will be to modulate the magnitude of an envelope or LFO with another envelope and/or LFO. On the other hand, modulating the FM signal using audio waveforms will provide additional harmonic content to your FM signal.
The Z2040 VCF can be used to generate a pure sine wave and act as a VCO. With no signal on the input and the resonance set to its maximum position, the module can oscillate a very low distortion sine wave. Despite not possessing an exponential 1V/Oct input, the Z2040 will track precisely over roughly seven octaves using MOTU Volta calibration. Modulating the VC-resonance and/or the FM inputs in self-oscillation mode will transform the sine wave and add harmonics.
