•FEATURES 96K Hz sampling frequency, 32-bit DSP processor, 24- bit A/D and D/A converter. 6 models available: 2 ins/4 outs, 2 ins/6 outs, 2 ins/8 outs, 3 ins/6 outs, 4 ins/6 outs, 4 ins/8 outs. USB and RS485 connectors are present for PC connection. 250 units can be connected together via Rs485 and it can be controlled remotely as far as 1500 meters. Convenient use of function buttons on either front panel or the included software interface displays. 30 user-program parameters can be stored into the device. Safety/security lock buttons provide peace of mind again unwanted changes from unauthorized users or unwanted set-up changes. 6 independent parametric EQ of input and output. The gain range is ±2 0 d B. The EQ of output channel has two slopes: Lo-shelf and Hi-shelf. 4 2×2 LCD blue back-light display present. 6 LED display an exact digital level meter (and mute and edit status of input/output). Every input and output has compensation-delay, phase control and mute settings, delay function offer a maximum of 1000ms. Adjustable gain & limiter of output channel; Just choose the input signal and copy all the parameters from one channel to another channel with joint debugging. •SPECIFICATIONMODEL XCA24 Input Channel & Socket Female XLR 2CHs, Output Channel & Socket Male XLR 4 CHs, Input Impedance Balance: 20KΩ Output Impedance Balance: 100Ω PC Com Port One USB Com Port on front panel, 2 RS485 Com Port on back panel(RJ-45) CMRR >78dB(1KHz) Input Range ≤+25dBu Frequency Response 20Hz-20KHz(-0.5dB) S/N R >118dB THD <0.01% OUTPUT=0dBu/1KHz Crosstalk of Channels >88dB(1KHz) Functions of Input Channels Input Mute Each channel has Independent Mute Control Input Delay Each channel has Independent Delay Control Range:0—1000ms stepover 21us@<10ms stepover="" 84us="" 10-20ms="" stepover:0="" 5ms="">20ms Input Polarity Same Phase + or reversed Phase - Input EQ Each Input Channel has 6 Bands Parametric EQ Central Frequency Point:20Hz-20KHz, 239 frequency points totally Band Width:0.01oct-3oct @ stepover is 0.01oct Gain:-20dB-+20dB @ stepover , 0.1dB Input gain Input gain range:-80dB~+12dB,This email address is being protected from spambots.
