Where it departs from tradition is in its two exclusive hyper-compression modes — Focus and Punch — which open up compression behaviour previously unavailable in any variable-bias tube unit. \u003cbr\u003e\u003cbr\u003eUnderpinning it all is SPL's proprietary 120V technology, operating at ±60V internally to deliver exceptional headroom, dynamic range, and signal-to-noise performance.\u003cbr\u003eThe Venos operates on the principle of a bias-controlled remote cutoff tube. The bias - the voltage on the tube's grid is the sum of the Input, Threshold, Rectifier, Mode, Attack, and Release parameter settings, giving the compressor a deeply interactive, musical feel. All controls are implemented with detented potentiometers or switches, covering both channels simultaneously for easy recall and auditioning.\u003cbr\u003e\u003cbr\u003eSix compression modes shape the behaviour of the sidechain signal path. The first three - Linear, Modern, and Vintage each integrate a different analogue filter into the sidechain, determining how the compressor responds to different parts of the frequency spectrum. Linear applies only a subsonic filter below 20Hz, Modern adds an analogue bandpass filter suited to contemporary mixes, and Vintage uses an empirically derived filter curve developed by SPL founder Wolfgang Neumann.\u003cbr\u003eThe two hyper-compression modes, Focus and Punch, take a fundamentally different approach. Rather than using a sidechain filter, a special circuit causes the compression characteristic curve to drop after reaching its maximum, a behaviour sometimes referred to as negative compression, where the ratio effectively inverts. Focus tightens the midrange while retaining size and life in the signal; Punch delivers an unmatched transient impact without harshness.\u003cbr\u003e\u003cbr\u003eAn external sidechain insert (Ext SC mode) allows a signal to be routed out via balanced XLR send\/return jacks to an outboard equaliser or any other device, with the processed signal fed back to control compression. Alternatively, a completely independent source can drive the sidechain. Three rectifier options — germanium, silicon, and LEDs further shape attack and release characteristics at a circuit level.\u003cbr\u003e\u003cbr\u003eAnalogue passive EQ presets AirBass and Tape are placed after the compression stage but before the output level control, allowing gentle tonal shaping as a final step. AirBass lifts both low and high frequencies by approximately 2dB; Tape emulates the typical frequency roll-off of a tape machine. A large VU meter displays gain reduction, with a calibration trimmer accessible on the front panel. A rear-panel ground-lift switch eliminates ground-loop issues.\u003cbr\u003e\u003cbr\u003eConstruction is equally considered: a 4mm-thick anodised aluminium front panel, solid milled aluminium knobs, a powder-coated steel chassis, and all key components mounted using through-hole technology for the best possible component selection. The Venos is manufactured entirely at SPL's facility in Niederkrüchten, Germany.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVariable-bias tube stereo bus compressor based on classic remote cutoff tube topology\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTwo exclusive hyper-compression modes: Focus (midrange-focused, large sound) and Punch (maximum transient impact)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThree analogue sidechain filter modes: Linear, Modern, and Vintage\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eExternal sidechain insert via balanced XLR send\/return for external EQ or independent sidechain sources\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThree rectifier options (germanium, silicon, LED) affecting attack and release character\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDetented potentiometers and switches throughout for consistent recall across both channels simultaneously\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eInput and Output level controls (±10dB, 41-step detented pots)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThreshold control (41-step detented pot); Bias control (41-step detented pot)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAttack and Release each switchable in 6 steps from Fast to Slow\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAnalogue passive EQ presets: AirBass (+2dB low\/high shelf) and Tape Roll-Off\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLarge VU meter displaying gain reduction with front-panel GR Cal. trimmer\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRear-panel ground lift switch\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSPL 120V technology: ±60V internal operating voltage via proprietary SUPRA op-amps\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e+32.5dBu maximum input\/output level — 12dB more headroom than standard ±15V designs\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eInternal linear power supply with shielded toroidal transformer\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eNeutrik XLR connectors with gold-plated contacts, electronically balanced I\/O\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e4mm anodised aluminium front panel; solid milled aluminium knobs; powder coated steel chassis\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAll key components are hand-soldered using through-hole technology\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eManufactured in Niederkrüchten, Germany\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSPL Venos Specifications:\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAnalogue Inputs \u0026amp; Outputs (XLR balanced)\u003cbr\u003e\u003cspan style=\"font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif; font-size: 0.875rem;\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif; font-size: 0.875rem;\"\u003eMaximum Input\/Output Level: 32.5 dBu\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003eInput Impedance: 20 kΩ\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eOutput Impedance: 75 Ω\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFrequency Range: 10 Hz – 40 kHz\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCrosstalk: -108 dBu\u003c\/li\u003e\n\u003cli\u003eTHD (+10 dBu): 0.002%\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eNoise (A-weighted): -98 dBu\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePower Supply\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eInternal operating voltage (audio): ±60V DC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRelay\/LED voltage: +12V DC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMains: 230V AC \/ 50Hz or 115V AC \/ 60Hz (selectable)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFuse (230V): T 1mA; Fuse (115V): T 2mA\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePower consumption: max. 47 VA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePhysical\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDimensions (W × H × D): 482 × 132 × 300 mm \/ 19 × 5.2 × 11.8 inches\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eUnit weight: 8.75 kg \/ 19.3 lbs\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eShipping weight (inc. packaging): 11.57 kg \/ 25.05 lbs\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPL","offers":[{"title":"Default Title","offer_id":58137516441974,"sku":"SSPLVENOS","price":3630.83,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0256\/2988\/4462\/files\/SPL-VENOS_0002_Layer1.jpg?v=1782222636","url":"https:\/\/studiocare.com\/products\/spl-venos-stereo-bus-tube-compressor","provider":"Studiocare","version":"1.0","type":"link"}
