The cabinet features microphone input(s) and line audio input(s) with isolated gain controls to mix audio in and out and an XLR audio out for daisy chaining additional speakers.

The mixer features bass / treble adjustments and independent gain controls for the inputs and overall volume. A 1/4" TRS / XLR Mic input and XLR / RCA Line input allows for multiple options depending on the performance the speaker is being used for. A large heat sink keep the amp cool and a switchable 115V / 230 voltage range allows for multiple power options.

Standing tall

All Harmony Audio pro audio speakers feature a built in 35mm speaker stand mount which in most cases is best way to set the speaker up for a performance. The Venue series speakers feature a steel metal plate on the bottom and the speaker simply slides into place. The Concert and Live series speakers features a molded plastic mount on the bottom and feature a knob to tighten speaker to the stand for increased stability.

Ready for the Road

The Concert series speakers feature a steel mesh woofer guard designed to take the impact from the daily grind. The cabinet features 3 heavy duty handles to help easily move the speaker and the molded impact resistant plastic absorbs the bumps of the road. If not using the speaker stand mount the cabinet has (4) rubber feet so it can also be set directly onto the floor.
