Oradea

A 20 HP quadruple analog resonator: four band-pass channels tuned over the whole audible range with V/oct tracking, their resonance reaching a Q of 300 without falling into self-oscillation, the peak gain compensated so that it does not grow with resonance. Each channel has an excite input that pings it with a uniform impulse, an exponential VCA with its level LED, its own output and a phase flip switch for the summed output.

Key features

• Four channels A to D: CENTER FREQ, PEAKING and LEVEL knobs, each with its CV input
• FREQ inputs calibrated to V/oct; ALL FREQ and ALL PEAKING inputs for all channels
• EXCITE inputs: an optimized uniform impulse for a long, controlled ping
• One audio INPUT feeding all four channels
• OUT A to D and a soft-saturated SUM OUT
• PHASE FLIP switch per channel on the signal sent to the sum
• PPM level LEDs: green up to 10 Vpp, yellow above, red over 16 Vpp
