Passive Variable Attenuator for Any Mic Do you find that your signal is constantly peaking when recording loud sources such as drums or guitar amps? Triton Audio's AirHead might be the perfect solution for you. The AirHead is a passive variable attenuator plug that's compatible with all types of microphones — even condensers — as the AirHead still enables +48V phantom power to reach your microphone, which is a touch that Sweetwater studio engineers love. With the AirHead, your signal can be continuously attenuated by -6dB to -18dB, thus enabling you to crank your preamp and capture more of its signature sonic character without overloading your signal and clipping. Additionally, AirHead's balanced XLR input and output ensure perfect integration into any setup.
