DP4.8II
Based on powerful DSP digital audio processor, it is an ideal choice for engineering installation applications, it combines the functions of traditional equipment with remote control capabilities, especially suitable for party rooms, electronic music rooms, bars, hi rooms, and Performance and sound reinforcement system.
Extraordinary sound quality performance. Based on the 192kHz digital sampling rate, it provides an audio bandwidth of more than 35kHz. The high-frequency resolution performance is delicate, the frequency domain expansion is wide, and the audio content is truly restored. Supports linkage adjustment between channels, supports optional security lock settings, supports Extended Simple Remote Communication Protocol

Single output channel speaker parameter management function (save and recall)
Batch export and import of device presets
In factory mode, support speaker manufacturer parameter lock hiding (intellectual property protection)
Under administrator privileges, you can set the running time (accumulated time) and boot times of the device
◆Optional lock settings
Each processing module of the input and output channels can be individually set to three states (display lock, adjustment lock, and no lock).
◆Support external central control protocol.
Through the RS232 or RS485 port, external third-party devices can send serial command codes to control some functions of the device (preset recall, volume increase or decrease, mute status of each channel).
◆USB, RS232, RS485 control port.
◆Imported Neutrik XLR connector
