Joranalogue Delay 1
Split-phase analogue BBD delay for modern synthesis
12 HP Eurorack module
Delay 1 is a fully analogue bucket brigade delay (BBD) module with a split-phase topology, offering 1 to 50 ms of delay time driven by an integrated temperature-compensated high-frequency VCO. Its compander circuit, voltage-controlled feedback filter, and dual blend outputs give it a warm, characterful sound suited for chorus, flanger, echo, comb filtering, and Karplus-Strong string synthesis.
Features
- Fully analogue bucket brigade device (BBD) delay line
- Delay time range: 1 to 50 ms
- Integrated temperature-compensated high-frequency voltage controlled oscillator (VCO)
- Clock frequency exceeds 20 kHz to eliminate audible BBD clock whine
- 1 volt per octave exponential response on Volt Per Octave TM input
- Secondary Time Modulation input with bipolar polariser knob
- Split-phase topology: positive (sum) and negative (difference) blend outputs
- Integrated high-performance compander for improved fidelity across signal levels
- Newly developed control circuit to reduce distortion and noise
- Integrated voltage-controlled filter in feedback path (damping) with lowpass/highpass switch
- Damping modulation input with polariser knob
- Feedback amount knob (0 to nearly 100%) with polarity switch (sum/anti)
Controls & Jacks (27)
- Fine — Fine-tunes the delay time for precise adjustment around the coarse setting.
- Time Mod. — Controls the depth of delay time modulation from external CV sources.
- Coarse — Sets the base delay time across the full range of the BBD delay line.
- Damping — Controls high-frequency damping in the feedback path, softening repeats for warmer tones.
- Blend — Sets the dry/wet mix between the original signal and the delayed signal.
- Feedback — Controls the amount of delayed signal fed back into the input, increasing the number of repeats.
- Damp. Mod. — Controls CV modulation depth of the damping parameter.
- Blend Mod. — Controls CV modulation depth of the dry/wet blend parameter.
- Feedb. Mod. — Controls CV modulation depth of the feedback parameter.
- V/Oct. LED — Indicates the V/Oct tracking status.
- Feedback LED — Indicates the feedback level status.
- Low/High — Selects between low and high delay time ranges.
- Anti/Sum — Selects between anti-phase and summed output modes from the split-phase BBD.
