S8 DSP by Hertz
The S8 DSP is an 8-Channel DSP from Hertz in a corrosion-resistant housing made of metal and composite materials. The signal processing occurs at 96 kHz and 24 Bit, including Hi-Res certification from JAS. A 32-Bit DSP manages 6 analog high/low-level input channels, one coaxial SPDIF input, and 8 output channels. For the outputs, there are level controls, a 15-band equalizer per channel, time delays, crossover filters, and polarity; for the inputs, a 7-band equalizer per channel. The bandwidth ranges from 10 Hz to 40 kHz, the signal-to-noise ratio is 105 dBA (analog input) and 112 dBA (digital input), THD+N is below 0.005 %, and channel separation is over 95 dBA. Control and setup are done via the BT app for iOS/Android in Configurator and DRC mode, as well as via PC/Mac, including the exchange of setup files via BT and four presets with selection via cable. The power supply operates with 7–20 VDC and ART Automatic Remote Turn-On/Off; Remote IN/OUT are specified. The housing measures 130 x 33.8 x 88.3 mm at 0.66 kg. The DSP chipset is the Analog Devices ADAU1451.
