The ARDENT 12M monitor uses a Kustom® speaker and high-quality compression driver, along with the Precision-Tuned Crossover system and Safety Surge protection circuit. Ardent monitors have two exclusive features: A Volume Attenuator controlthat lets performers adjust the overall level of their personal monitor while on stage -- accomplished with an internal Multi-Tap Transformer -- and an Impedance Switch that when activated, lets performers use additional stage monitors without the need for another monitor amplifier!
