Instruō's dual analogue all-pass filter in 4 HP, its first dedicated effects processor: two all-pass filters that leave every frequency's level as it is and shift their phase across the spectrum, each with its LED phase slider and a phase CV input with its attenuverter, a 1-Pole / 2-Pole switch for channel 1, a global 1V/oct input and an indicator on channel 2's output. Its inputs and outputs normal from one channel to the other, for phase shifting, stereo enhancement and Doppler-like effects.

Key features

• Two parallel analogue all-pass filters
• Independent attenuverters for phase CV
• 1-Pole / 2-Pole slope for channel 1 (180° or 360° sweep)
• Cascaded normalisation: mono, mono-to-stereo, stereo
• Global 1 V/oct tracking
