Recommended Accessories

Radio Design Labs' ST-CX2 is a line-level two band crossover to drive audio power amplifiers. 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.

The 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.

NOTE: Radio Design Labs' PS-24AS power supply is NOT included but is required in order to power this product.  Please see the "Accessories" tab or click here for more information on the PS-24AS power supply.

The 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.

For 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.

Features:

  • Active Low-Frequency Woofer Equalization
  • Active Full-Range Equalization
  • Adjustable Equalization
  • Crossover with Loop-through Output
  • Low-Noise and Low-Distortion Crossover
  • RDL® SupplyFlex™ Power Input Configuration
