Filter 8 by Joranalogue

Features

• Analogue 'OTA style' cascaded 4-pole lowpass VCF with self-oscillation capability.
• Filter outputs: 1-through-4 pole lowpass, 1-pole highpass, band boost+notch, phase shifter, 4-pole bandpass.
• Self oscillation: 8-phase sine waves, separated by 45°.
• Accurate temperature-stable sine wave VC(LF)O with fine and coarse tuning.
• Simultaneous exponential and linear FM, including depth polarisers, dedicated 1 volt/octave input and LFM AC-coupling switch.
• Unique voltage controlled resonance topology: all outputs resonate with absolutely no loss of low frequency response, unlike common 'bass compensation' methods.
• Resonance compensation gain switch: adjusts output gains for equal amplitude self-oscillation (10 Vpp).
• LF mode for slew modifier or LFO use. Ultra-wide total frequency range: 2.8 mHz (6 minutes) to 27 kHz, a range of nearly 10,000,000:1
• Dual signal inputs increase patching flexibility.
• Impedance-compensated outputs with dual-colour LEDs.
• Voltage hold feature 'freezes' the filter core. Pause LFO modulations, or create pulse-width-sensitive sync sounds at audio rates. Also useful as clickless output mute. Manual or gate control.
• Dedicated ping trigger input: 'strike' the filter core using any trigger or gate signal and easily create percussive sounds with 8 different timbres.
• Trim potentiometers accessible from the front panel.
• Size: 12HP
• Depth: 30mm
• Power: +12: 75 mA, −12: 75 mA
