Description
Subwoofer Crossover Filter
The ST-CX2S is a subwoofer signal equalizer in the STICK-ON series of products from RDL. The ST-CX2S offers flexibility in equalization adjustment, with the exceptional performance of RDL.
The ST-CX2S features two separate, isolated balanced bridging inputs which may each be wired balanced or unbalanced. The output driver is 150 Ω balanced which can drive low or high impedance balanced or unbalanced lines. The module operates at unity gain at 63 Hz (balanced input to balanced output). A BOOST control permits adjustment of the output at 32 Hz from flat to +5.5 dB.
The ST-CX2S features RDL's SupplyFlex power input configuration for operation directly from ground-referenced, floating or bipolar 24 Vdc power.
