The input and outputs are balanced and may be connected unbalanced if necessary. The input accepts a +4 dBu line-level signal. The module operates at nominal unity gain.\u003c\/p\u003e\n\u003cp\u003eThe FULL RANGE output is designed for use with full-range speaker systems which do not contain a woofer (below 100 Hz). The passband is 100 Hz to 30 kHz, with an equalization adjustment centered at 2 kHz. Through the application of a smile-curve providing up to 8 dB attenuation through midband audio frequencies, the performance of the whole system may be significantly enhanced.\u003c\/p\u003e\n\u003cp\u003eThe WOOFER output is designed for use with woofers amplified independently of any full-range speakers. The passband is 40 Hz to 165 Hz when set flat, with an equalization BOOST adjustment centered at 50 Hz.\u003c\/p\u003e\n\u003cp\u003eFor systems also incorporating subwoofers, the LOOP THRU output connects to an input of the RDL ST-CX2S Subwoofer Crossover. The ST-CX2 features RDL's SupplyFlex power input configuration for operation directly from ground-referenced, floating or bipolar 24 Vdc power.\u003c\/p\u003e\n\u003ch2\u003eFeatures:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eActive Low-Frequency Woofer Equalization\u003c\/li\u003e\n\u003cli\u003eActive Full-Range Equalization\u003c\/li\u003e\n\u003cli\u003eAdjustable Equalization\u003c\/li\u003e\n\u003cli\u003eCrossover with Loop-through Output\u003c\/li\u003e\n\u003cli\u003eLow-Noise and Low-Distortion Crossover\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:50 kΩ balanced line-level (+4 dBu)\u003c\/li\u003e\n\u003cli\u003eOutputs (2):150 Ω balanced line-level (+4 dBu)\u003c\/li\u003e\n\u003cli\u003eHeadroom:\u0026gt; 18 dB\u003c\/li\u003e\n\u003cli\u003eGain:Unity (nominal, equalization set flat)\u003c\/li\u003e\n\u003cli\u003eOut-of-Band Rolloff:18 dB\/octave\u003c\/li\u003e\n\u003cli\u003eFULL RANGE Output:\u003c\/li\u003e\n\u003cli\u003eFrequency Response:100 Hz to 30 kHz (+\/- 0.5 dB)\u003c\/li\u003e\n\u003cli\u003eTHD+N:\u0026lt; 0.075% (100 Hz to 30 kHz\u003c\/li\u003e\n\u003cli\u003eResidual Noise:\u0026lt; -80 dB (referred to +4 dBu)\u003c\/li\u003e\n\u003cli\u003eWOOFER Output:\u003c\/li\u003e\n\u003cli\u003eFrequency Response:40 Hz to 165 Hz (+\/- 0.5 dB)\u003c\/li\u003e\n\u003cli\u003eTHD+N:\u0026lt; 0.025% (40 Hz to 165 Hz)\u003c\/li\u003e\n\u003cli\u003eResidual Noise:\u0026lt; -95 dB (referred to +4 dBu)\u003c\/li\u003e\n\u003cli\u003ePower Requirement:GROUND-REFERENCED or FLOATING 24 Vdc @ 40 Ma\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":42494496473266,"sku":"RDL STCX2","price":259.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0614\/8122\/2322\/products\/ST-CX2.jpg?v=1754405268","url":"https:\/\/www.performanceaudio.com\/en-ca\/products\/radio-design-labs-st-cx2-two-band-active-line-level-crossover","provider":"Performance Audio","version":"1.0","type":"link"}
