On stage, the SD1 bodypack keeps the performer in touch with the monitor mix, the band, and the audience. Pressing the momentary switch on the top of the volume knob will scroll the performer through the four memory presets. An audible beep corresponds to the preset number selected.

The SD1 bodypack also features a dual-concentric volume knob for independent fine-tuning of the ambient and the monitor signal levels during performance. Forget about changing the battery every night because SD1 delivers over 300 hours of use from a single AA battery.
