Details

The CX311 is a stereo 2-way crossover with a dedicated subwoofer section.

It features Linkwitz-Riley filters to guarantee in-phase outputs at all frequencies. This ensures proper acoustic summing of common signals from adjacent drivers in the crossover region.

Each channel has discrete controls for low and high output levels, a variable crossover frequency from 250 Hz to 6 kHz, a switchable low-cut filter to eliminate rumble, and a switchable phase invert.

Both input channels are combined in the subwoofer section, where you can set the frequency below which the summed signal is sent to the subwoofer output.

The rear panel has XLR and 1/4 TRS connections for the inputs, and 1/4 TRS connections for all outputs.

Packed into a fully shielded 1U steel enclosure, the CX311 is an ideal crossover solution for stereo PA systems with a subwoofer.
