dbx 223xs Stereo 2-Way/Mono 3-Way Crossover with XLR ConnectorsMore sound to your amps and speakersThe secret to making speakers sound great lies with the crossover you use. With the dbx ƒ???????? ?? 223xs Crossover you'll get great performance, ultra low-noise, rugged reliability and four decades of dbx knowledge and expertise in building the world's finest processors. The 223xs uses precision filters to separate the audio signal and direct the correct frequencies to your loudspeaker drivers. By directing only the specific frequency bands to each speaker driver the 223xs leaves your amplifiers free to use their full power on the usable signal eliminating distortion and giving your PA system a cleaner and better sound.The dbx 223xs is a dual channel crossover with all the features you would expect from a professional product. It features Linkwitz-Riley 24dB per octave filters, independent output gain controls for level matching, output phase inversion, 40 Hz low cut filter, and optional mono summing of the low frequency (subwoofer) output. Everything in the design exudes great precision from the solid "click" controls to the high quality XLR inputs and outputs.Features:- XLR balanced ins and outs- Mode switch for stereo 2-way or mono 3-way operation- Low frequency summed (subwoofer) output- x10 range switch on both channels- 40Hz high pass (low cut) filter both channels- Phase reverse switch on all outputs- Individual level controls on all outputs- 24dB per octave Linkwitz-Riley filters (the professional standard)- Stereo/Mono status LEDs indicate the selected mode- dbx ƒ???????? ?? 2 year parts and labor as standard- CSA NRTL/C approved- CE compliantSpecifications:Input Connectors: XLR (pin 2 hot)Input Type: Electronically balanced/unbalanced, RF filteredInput Impedance: Balanced >50k ohm, unbalanced >25k ohmMax Input: >+22dBu balanced or unbalancedCMRR: >40dB, typically >55dB at 1kHzOutput Connectors: XLROutput Type: Impedance-balanaced/unbalanced, RF filteredOutput Impedance: Balanced 200 ohm, unbalanced 100 ohmMax Output: >+21dBu balanced/unbalanced into 2k ohms or greaterBandwidth: 20Hz to 20kHz, +/-0.5dBFrequency Response: < 3 Hz to > 90 kHz, +0/-3 dBSignal to Noise Ratio: Ref: +4 dBu, 22 kHz measurement bandwidthSignal-to-Noise (Stereo Mode): >94dB (Low Output), >91dB (High Output)Signal-to-Noise (Mono Mode): >94dB (Low Output), >93dB (Mid Output), >91dB (High Output)Dynamic Range: > 106 dB, unweighted, any outputTHD+Noise: < 0.004% at +4 dBu, 1 kHz; < 0.04% at +20 dBu, 1 kHzInterchannel Crosstalk: < -80 dB, 20 Hz to 20 kHzCrossover Frequencies (Stereo Mode): Low/High: 45 to 960 Hz or 450 Hz to 9.6 kHz (x10 setting)Crossover Frequencies (Mono Mode): Low/Mid: 45 to 960 Hz or 450 Hz to 9.6 kHz (x10 setting); Mid/High: 45 to 960 Hz or 450 Hz to 9.6 kHz (x10 setting)Crossover Filter Type: Linkwitz-Riley, 24 dB/octave, state-variableLow cut Switch: Activates 40 Hz Butterworth, 12 dB/octave high-pass filter, one switch per channel.Phase Invert Switch: Inverts the phase at the output, one switch per output.x1 / x10 Switch: Multiplies the low-high(mono: low/mid and high/mid) crossover frequency range of the front-panel markings by a factor of 1 or 10, one switch per channel.Mode Switch: Selects stereo/mono and 2/3-way operationLF Sum Switch: Selects normal (stereo) or mono-summed low frequency operation and disables Ch 2 ƒ???????? ƒ???????? s low output phase invert LED to indicate that this output is not operational in the LF sum mode.Indicators: Stereo Operation (Green); Mono Operation (Yellow); Low Cut (Red-per channel); x10 (Green-per channel); Phase Invert (Red-per output)Operating Voltage: 100 VAC 50/60 Hz; 120 VAC 60 Hz 230 VAC50 HZOperating Temperature: 32 ƒ???????? ???F to 113 ƒ???????? ???F (0 ƒ???????? ???C to 45 ƒ???????? ???C)Power Consumption: 15WPower Connector: IEC receptacleDimensions: 1.75" H X 19" W X 6.9" D (4.4cm x 48.3cm x 17.5cm)Shipping Weight: 5.4 lbs.
