Signet's PDA500/2 current mode audio-frequency induction loop amplifier has been established and proven, over a number of years, providing outstanding sound quality at a competitive price. The PDA500/2 is ideal for use in square rooms up to 500m and rectangular rooms up to 600m. (with an aspect ratio of 2:1)
The amplifier includes one balanced microphone input and one switchable balanced microphone or line level input, both of which accept standard 3 pin XLR connectors. The is also a switchable optional 12V phantom power available on both
inputs to allow the use of electret or condenser microphones.
