AlphaTheta Corporation announces a host of new models in the DM series of desktop monitor systems from its Pioneer DJ brand. The new DM-50D-BT integrates Bluetooth functionality into the DM-50D speakers, which were released in late 2021. Pioneer DJ’s DM-40 models also received an upgrade to help deliver a more optimal listening experience. The updated speakers offer Bluetooth-connection capability and system upgrades to the compact DM-40 models. All models are available in black or white and sold in pairs. Artists can easily connect their DJ setup or home studio to the RCA and mini-jack input terminals on the DM series speakers. The DM-50D-BT and DM-50D also have a TRS input, and the speakers’ Bluetooth models enable artists to connect mobile devices for cable-free high-quality music playback wirelessly. The volume knob and headphones socket are on the front panel for quick connection and level control.
