LDMS828 - 19" Line Mixer 8 in 2 and Splitter 2 in 8
The LD Systems LDMS828 is a mixer, splitter, and booster amplifier in 19” rack format for flexible live and studio applications.
The LDMS828 has one stereo and six mono channels with individual LED level metres; all inputs and outputs are electronically balanced. Two mono channels are equipped with stereo TRS sockets, the other connectors are XLR sockets. The stereo channel has individual volume controls for input and output and a link button for looping through the signal; each mono channel has volume and panorama controls as well as a button that toggles between the splitter and mixer functions.
TheLDMS828 by LD Systems is impressive not only because of its practical features, but also because of its technical specifications. The broad frequency response of 5 - 40,000 Hz, a dynamic range of 85 dB, and the extremely low total harmonic distortion of 0.0008% guarantee maximum signal fidelity. The nominal working level of -10 dBV to +4 dBU makes the mixer/splitter suitable for connection to both professional and consumer equipment.
