Radial Engineering HotShot 48 Phantom Power Supply and Footswitch

The HotShot 48V is a condenser microphone switcher built for silent operation on stage, allowing an artist to power their vocal mic and reroute it to feed the stage monitoring system for communicating with other band members or technicians at the press of a footswitch. LED indicators display the active output, and the footswitch itself can be configured for latching or momentary action. While the HotShot 48V is specifically designed to address issues when switching condenser microphone outputs, it works equally well with dynamic mics also.

Silent condenser mic switching

Passive audio switchers occasionally create an audible pop during switching that can be heard through the PA system, disrupting the performance. This can be caused by the introduction of phantom power or by stray DC offset from any powered device connected to the switcher. The HotShot 48V employs active circuitry and a time delay microcontroller for silent switching under any conditions, allowing you to use condenser or dynamic microphones with no noise whatsoever. A five millisecond delay is introduced when the switching relay is activated, short enough to go unnoticed by the artist, but long enough for any DC leakage to dissipate, preventing audible noise and ensuring seamless switching during any performance.
