The ATW-R3250DF2 3000 Series wireless in-ear monitor receiver delivers pro features at a price most musicians, techs, small-to-mid-sized venues and houses of worship can afford. Antenna diversity bolsters RF stability if the audience crowds the stage (the human body can actually reflect or absorb RF energy), line of sight between transmitter and receiver is impeded by the venue, or if the lighting rig and other RF noise generators (phones, computers and so on) seek to jam up your wireless signal. An onboard headphone amp produces pristine audio, and you can choose to monitor in stereo or mono, as well as make your own EQ adjustments to tailor the sound to your needs. The ATW-R3250DF2 makes tweaks and alerts easy to see with a high-resolution OLED screen that can be viewed on dark indoor stages and sun-drenched outdoor gigs.
