4 in 8 out Digital Speaker Management System with Digital I/O
192KHz sampling frequency, 32-bit DSP processor, 24-bit A/D and D/A converter.
Digital signal input channels that come with 2 digital coaxial (spdif) ins and 2 optical ins. }
Digital signal output channels come with 4 digital coaxial (spdif) outs and 4 optical outs.
USB and RS485 connector present. 250qty of this device can be connected together via RS485 and controlled remotely from as far as 1500 meters away.
Operation of functions can be controlled from front panel directly (if needed).
30 kinds of programs can be stored into the device.
Parameters can be security-locked by setting a password on the front panel and software interface.
Each input and output channel comes with 6-bands of independent parametric EQ. Gain is adjustable from -60dB to +12dB. In addition, EQ of output channel can be chosen as Lo-shelf or Hi-shelf.
Input channels come with 6-bands of independent parametric EQ. Output channels come with 15-bands of parametric EQ.
Built with a beautiful 4.3” Color LC (with pixels of 480 x 272 RGB).
13-bands of digital LED level-meters for status of input, output, mute and edit.
Compensation-delay, phase-control and mute settings present for each input and output channel. The delay function offers a maximum adjustment of 1000ms (and can be displayed as millisecond, meter and feet (all together at once).
Input channels have the following parameters: Gain, Noise gate, Delay, Polarity and Parametric EQ.
Output channels have the following parameters: Gain, Delay, Polarity, Crossover, Compressor/Limiter, Matrix and Parametric EQ. Includes a internal signal generator (pink noise, white noise, etc).
Includes master password option (blocking unwanted or unauthorized use of the unit).
Matrix and mute in channels can be controlled by connecting a mixer and the device by USB or RS485. Specification
