NEW BAXS ครอสโอเวอร์แบบอิเล็กทรอนิกส์ 234XS 2/3 พร้อมความสูงที่ปรับได้สำหรับ KTV/แถบเวที COD

234XS: Stereo three-way, mono three-way electronic crossover. TRS or XLR differential balanced inputs and outputs with choice of stereo or subwoofer synthesized by summing the left and right channels. Both channels have x10 range selector switches. Both channels have 40Hz high-pass filters (bass frequency cutoff). All outputs have phase reversal switches. Therefore, the output level on each frequency band can be independently adjusted in dB/oct Linkwitz-Riley filter (professional standard). Stereo/mono status indicator LED light indicates the selected working mode of the unit. Function introduction: TRS or XLR differential balanced inputs and outputs selectable stereo or subwoofer synthesized by adding left and right channels Both channels have Phase reversal switch, so the output level on each frequency band can be independently adjusted 24dB/oct Linkwitz-Riley filter (professional standard) Stereo/mono status indicator LED, indicating the unit's selected operating mode. Input interface: 1/4 inch TRS type: electronically balanced/unbalanced, with RF filter Impedance: balanced >50k ohms, unbalanced >25k ohms Maximum input level: >+24dBu balanced or unbalanced common mode rejection ratio CMRR: >40dB, typical value >50dB, 1kHz Output interface: 1/4 inch TRS type: Impedance balanced/unbalanced, with RF filter Impedance: balanced 200 ohms, unbalanced 100 ohms Maximum output level: connected to a load of more than 2k ohms, >+21dBu Balanced or unbalanced working performance Bandwidth: 20Hz-20kHz, +0/-0.5dB Frequency response: <3Hz-90kHz, +0/-3dB Signal-to-noise ratio: Reference value: +4dBu, 22kHz measurement bandwidth Stereo mode single Channel mode low frequency output: >94dB > 94dB Mid frequency output: > 93dB high frequency output > 92dB > 92dB Dynamic range: > 114dB, unweighted, any output distortion + noise: < 0.004% + 4dBu, 1kHz < 0.04% + 20dBu , 1kHz inter-channel crosstalk: <-80dB, 20Hz-20kHz The function of the crossover is to separate the high, medium and bass, connect them to multiple power amplifiers and then to their respective speakers, and use them with a subwoofer to achieve the bass effect. Two-way: connect 2 amplifiers and 4 speakers Three-way: connect 3 amplifiers and 6 speakers
