{"product_id":"43911","title":"Bugbrand Phase 12 All-Pass Filter","description":"\n\u003cp\u003eA six-pole analogue phase shifter built around 12 all-pass filter stages and three 2164 quad-VCA chips. Designed for studio and performance use, it offers balanced TRS audio connections, CV control and hands-on control of phasing, feedback and modulation.\u003c\/p\u003e\n\u003cp\u003eThe all-pass stages shift the phase of the signal at their filtering frequency while preserving amplitude. Mixing the dry and processed signals creates the characteristic peaks and notches of phasing. The main Phase control sets the filter centre frequency across the full audio spectrum, with internal or external modulation available for animated sweeps and more complex movement.\u003c\/p\u003e\n\u003cp\u003eThe main input accommodates typical line-level signals, with up to 20dB variable gain and soft clipping for added overdrive. A separate feedback input is normalised from the phase output; inserting a jack breaks this connection, allowing the feedback path to be processed externally. Buffered outputs provide both mixed dry\/wet and pure wet phase signals.\u003c\/p\u003e\n\u003cp\u003eFeedback can be increased to emphasise the filtering up to the edge of resonance. The Add\/Subtract switch inverts the phase output and feedback input, providing two distinct response modes. An internal jumper selects whether feedback returns to the first or second filter stage; it is set to the second stage as standard.\u003c\/p\u003e\n\u003cp\u003eAn internal sine-wave LFO provides traditional sweep modulation at approximately 0.08–10Hz, while the external modulation input accepts CV sources such as sequencers. The LFO is also available via a dedicated ±5V banana output. At low LFO rates, the oscillator may take some time to reach full strength after powering on.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSix-pole analogue phaser with 12 all-pass filter stages\u003c\/li\u003e\n\u003cli\u003eBuilt around three 2164 quad-VCA chips\u003c\/li\u003e\n\u003cli\u003eBalanced TRS input and output connections\u003c\/li\u003e\n\u003cli\u003eVariable input gain up to 20dB with soft clipping\u003c\/li\u003e\n\u003cli\u003eNormalised feedback path with external feedback insert capability\u003c\/li\u003e\n\u003cli\u003eDry\/wet mix output plus buffered wet-only phase output\u003c\/li\u003e\n\u003cli\u003eAdd\/Subtract phase and feedback response switch\u003c\/li\u003e\n\u003cli\u003eInternal feedback-stage jumper selection\u003c\/li\u003e\n\u003cli\u003eInternal sine-wave LFO, approximately 0.08–10Hz\u003c\/li\u003e\n\u003cli\u003eExternal CV modulation input with polarity\/mute switch\u003c\/li\u003e\n\u003cli\u003e±5V LFO banana output\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAudio inputs:\u003c\/strong\u003e Mono balanced 1\/4\" TRS jack, 20kΩ impedance  \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAudio outputs:\u003c\/strong\u003e Mono impedance-balanced 1\/4\" TRS jack, 100Ω impedance  \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCV connections:\u003c\/strong\u003e 4mm banana  \u003c\/li\u003e\n\u003cli\u003eCV input impedance: 100kΩ  \u003c\/li\u003e\n\u003cli\u003eLFO output impedance: 470Ω  \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eEnclosure \u0026amp; Power\u003c\/h3\u003e\n\u003cp\u003eThe standalone unit is housed in a custom aluminium enclosure measuring 4.5 × 5.25 × 3.5 inches, with PCB-material front and side panels.
