The DL 210 iOS mixer app installed on an iPad or iPad mini will communicate wirelessly via local wifi to the Williams Sound PLA DL210 NET Induction Loop Amplifier. This mixer app will allow the user to control the inputs and outputs of the amplifier with full access to trims, FX and EQ. The app will also provide access to calibration tools giving an installer the ability to calibrate to IEC loop standards (with the use of the PLM FSMP field strength meter) while situated in the looped area.
