311 - 2way Crossover w/ Subwoofer Out Overview
The 311 Crossover may be used as a stereo 2-way crossover network and has the addition of
the subwoofer output for low-end frequency reinforcement. It employs 24dB / octave state-variable,
Fourth-order Linkwitz-Riley filters that guarantee properly phased outputs at all frequencies which
is optimal for the proper acoustic summing of common signals from adjacent drivers in the crossover
region. Each channel features independent high and low output level controls and a crossover
frequency rotary control which covers a wide range (250hz to 6khz). All three outputs have a 30
cycle low cut switch to eliminate low-end rumble. The subwoofer features an independent output
level and rotary control for frequencies in the 50hz to 250hz range.

Independent output level and rotary control (50hz to 250hz) | Advanced Feedback Suppression Processor with Full LCD Display
The AFS2 Dual-Channel Advanced Feedback Suppression Processor from DBX protects your ears and audio equipment from annoying and potentially damaging audio feedback without altering your sound. The AFS2 features application-specific filter types for speech, music low, music medium, and music high. The 24 fixed or live narrow-band notch filters are capable of removing frequencies at 1/80 of an octave, ensuring an optimal frequency response without the possibility of feedback.
The front panel features the wizard function to take the guesswork out of setting up any room by incorporating an advanced feedback suppression module and providing a full LCD display for system settings and menus. Additionally, the AFS2 offers a five-segment LED for accurately monitoring input levels for each channel, while the notch filter indicator allows you to monitor the number of filters applied. Dedicated bypass buttons are included to help isolate problem channels. The rear panel offers XLR and 1/4" inputs and outputs, both switchable between +4 and -10 dB operations. A USB port has been provided for firmware updates. The AFS2 ships with a standard IEC power cable.
