Verbos Electronics Dual Four Pole

£419.00
With free UK shipping
Dual Four Pole module by Verbos Electronics revives an all discrete hi and low pass filter design from the golden age of electronic music in the 1960s. The module contains a 4 pole hipass filter and a 4 pole lowpass filter each with two reversing attenuators on the cutoff control inputs, each with voltage controlled resonance added. There are no ICs in the signal path.

Details

Like a time traveler from the tape music studios in San Francisco and New York in the 1960s, this dual filter (based on the core of a classic all discrete transistor filter built way back then), arrives to your studio. The left side is a hipass filter with two cutoff CV inputs, each with a reversing attenuator and voltage controlled resonance. The right side is a lowpass filter with two cutoff CV inputs, each with a reversing attenuator and voltage controlled resonance.

These old school filters will not self oscillate, but they will screech and growl with the best of them. No IC amplifiers anywhere in the signal path

The Hi-Pass Filter
The hi pass filter section has a large “Frequency” control for setting the cut off frequency initially. Then, two reversing attenuators on c.v. inputs to mix with the panel control. There is a panel control to add resonance and a c.v. input to control resonance amount remotely. This filter will not self oscillate.

The Low-Pass Filter
The lowpass filter section has a large “Frequency” control for setting the cut off frequency initially. Then, two reversing attenuators on c.v. inputs to mix with the panel control. There is a panel control to add resonance and a c.v. input to control resonance amount remotely. This filter will not self oscillate. The output of the hipass filter is normalled to the input of the lowpass section. If two control voltages are multed to one c.v. input on each filter, with one c.v. set to fully clockwise on both sides and the other c.v. set fully clockwise on lowpass and fully counter-clockwise on hipass... The module will act as a four pole bandpass filter.
