The input and output are line level and each may be wired balanced or unbalanced. Trimmers provide adjustment for all usual professional and consumer audio input and output levels. Internal detectors feed three timing circuits. The threshold level and slope of each timing circuit are incremented to respond sequentially to signals of varying amplitude and energy levels. The ST-CL2 features a soft-knee compression threshold and compression ratio which automatically adjust to the program material. Two LED indicators cover the incremental ranges of compression, making setting of the input level quick and easy. Two ST-CL2s may be strapped together for stereo operation by connecting the coupling terminals between the two modules.\u003c\/p\u003e\n\u003ch2\u003eFeatures:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePositive Audio Level Protection\u003c\/li\u003e\n\u003cli\u003eSmooth Inaudible Gain Reduction\u003c\/li\u003e\n\u003cli\u003eTight Audio Peak Control\u003c\/li\u003e\n\u003cli\u003eVery Low Noise Compressor\u003c\/li\u003e\n\u003cli\u003eMulti Stage Incremental Gain Reduction\u003c\/li\u003e\n\u003cli\u003eFully Automatic Operation\u003c\/li\u003e\n\u003cli\u003eSuperb Performance with Minimal Setup\u003c\/li\u003e\n\u003cli\u003eRDL SupplyFlex Power Input Configuration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eInput:10 kΩ Balanced (may be connected unbalanced)\u003c\/li\u003e\n\u003cli\u003eInput Signal Range:-10 to +4 dBu, adjustable (for 6 dB gain reduction); +22 dBu maximum\u003c\/li\u003e\n\u003cli\u003eOutput:150 Ω Balanced (may be connected unbalanced)\u003c\/li\u003e\n\u003cli\u003eOutput Signal Range:OFF to +8 dBu, adjustable\u003c\/li\u003e\n\u003cli\u003eFrequency Response:10 Hz to 20 kHz (+\/- 0.2 dB) over full compression range\u003c\/li\u003e\n\u003cli\u003eNoise below +4 dBu output:\u0026lt; -78 dB (unweighted; +4 dBu input\/output)\u003c\/li\u003e\n\u003cli\u003eTotal Harmonic Distortion:\u0026lt; 0.05% @ 1 kHz below compression threshold;\u003c\/li\u003e\n\u003cli\u003e\u0026lt; 0.1% @ 1 kHz with 3 dB gain reduction;\u003c\/li\u003e\n\u003cli\u003e\u0026lt; 0.15% @ 1 kHz with 6 dB gain reduction\u003c\/li\u003e\n\u003cli\u003eCMRR:\u0026gt; 60dB (50 to 100 Hz)\u003c\/li\u003e\n\u003cli\u003eAttack Time:Averaging Compressor: 500 ms (+4 dBu input);\u003c\/li\u003e\n\u003cli\u003eFast Compression: \u0026lt;10 ms (+20 dBu input);\u003c\/li\u003e\n\u003cli\u003ePeak Limiting: Instantaneous\u003c\/li\u003e\n\u003cli\u003eRelease Time:Automatically adjusting up to 500 ms\u003c\/li\u003e\n\u003cli\u003eCompression Ratio:Automatically adjusting 1.5:1 to 10: 1\u003c\/li\u003e\n\u003cli\u003ePeak Limiter:INF:1\u003c\/li\u003e\n\u003cli\u003eInterconnection:Stereo COUPLE interconnection provided\u003c\/li\u003e\n\u003cli\u003eIndicators (2):Yellow LED for NORMAL Compression,\u003c\/li\u003e\n\u003cli\u003eRed LED for HEAVY Compression\u003c\/li\u003e\n\u003cli\u003ePower Requirement:24 Vdc @ 50 mA, SupplyFlex\u003c\/li\u003e\n\u003cli\u003eAmbient Operating Environment:0 C to 55 C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RDL","offers":[{"title":"Default Title","offer_id":42494496178354,"sku":"RDL STCL2","price":311.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0614\/8122\/2322\/products\/ST-CL2.jpg?v=1754405160","url":"https:\/\/www.performanceaudio.com\/en-ca\/products\/radio-design-labs-st-cl2-compressor-limiter-line-level","provider":"Performance Audio","version":"1.0","type":"link"}
