The CX2310 stereo 2-way/mono 3-way crossover provides amazing-accurate audio frequency separation, thanks to its state-of-the-art circuitry, superior-grade components, ultra low-noise op amps and balanced I/O connectivity. Additionally, the CX2310 features an independently-adjustable Subwoofer Output, effectively providing an extra low-frequency band a control range from 10 - 235 Hz. By using 1% metal film resistors, along with other extremely tight-tolerance components, the CX2310 is able to guarantee surgically-precise frequency selection with incredibly-low thermal noise. Put simply, the easy-to-use SUPER-X PRO CX2310 is one of the best-sounding crossovers in its class! The CX2310 provides two modes of operation: 2-way stereo, for Left and Right Lows (woofers) and Highs (tweeters); and 3-way mono, for Lows, Mids and Highs. In either mode, there is an additional output provided for a mono Subwoofer, with its own Frequency and Level controls. This extra feature effectively turns the CX2310 into a stereo 2-way + mono 1-way, or a mono 4-way frequency crossover. The Subwoofer Output is presented in mono, since people perceive extremely-low bass frequencies as being omnidirectional. For your convenience, the CX2310Õs front panel features an elegant and easy-to-read LED matrix, so you can see at a glance which operating mode has been selected Ð and which controls are currently active. ¥ Professional stereo 2-way/mono 3-way crossover featuring state-of-the-art Linkwitz-Riley filters with 24 dB/octave ¥ Additional subwoofer output with independent Frequency control ¥ Absolutely flat summed amplitude response, zero phase difference ¥ Individual output Gain controls for all bands ¥ Individual output Mute switches for easy band adjustment ¥ Individual Phase reverse switches for instant phase correction ¥ Switchable 25 Hz Low cut filter on each input for low-frequency driver protection ¥ Servo-balanced and gold-plated XLR connectors for all inputs and outputs ¥ Ultra-high precision potentiometers for ultimate accuracy and repeatability ¥ Illuminated switches for secure operation in dark stage environments ¥ Internal switch-mode power supply (100 - 240 V~) for noise-free audio and low power consumption ¥ Designed and engineered in Germany
