AC48II
Key Features
48kHz sampling rate, 40-bit DSP processor, 24-bitAD/DA convertor
Input processing includes Gain, Mute, Link, High-cut, Low-cut, Noise gate, 5PEQ, Phase, Delay.
Output processing includes Crossover, 6PEQ, Gain, Mute, Compressor/Limiter, Phase, Delay, Link.
Every input and output can do matrix assign freely
Adjustable PEQ frequency, Gain and Bandwidth, the gain step is 0.1dB, we can choose style: Peak, H-shelf, L-shelf, LP-6dB, LP-12dB, HP-6dB, HP-12dB.
The style of all High-cut, Low-cut filter and Distributor Unit: Butterworth, Linkwitz-Riley, Bessel, Slope is -6dB/oct ~ -48dB/oct.
Adiustable compressor/limiter threshold, soft knee, ratio, attached time and release time. Noise gate’s threshold, hold time, attached time and release time can be adjustment
The parameters of input and output adjusting are linkable, revisable input and output channels
All delay module’s delay time can reach over 680ms the step is 0.021ms.
Parameter setting of each channel can copy freely, build-in signal generator.
Input and Output on the front panel are equipped with 5-segment high precision level indicators, key indicators, security protection function.
30 user presets, 1 factory preset, device parameter and single preset file can save in computer; it also can download from computer and save in the device. The device itself can store multiple preset parameters and recall freely. With PC software, one-key online made the operation more convenient
USB and RS232 controlling ports, Online remote control and 255 units linkable through RS485.
