The PRX150-Pro is a power attenuator designed to be used with tube amplifiers and it allows guitarist to achieve the much desired "fully cranked up" tone from their tube amp, but at more practical volume levels. Utilizing its unique and innovative "Speaker Resonance Thru" (SRT) technology, the PRX150-Pro allows the speaker to fully maintain its natural reactance. As a result, the PRX150-Pro allows the amplifier's original, "cranked up" tone to be maintained at reduced volume levels. The PRX150-Pro is engineered to take the power and the heat. With its continuous 150 watt power rating, the PRX150-Pro is designed to handle the brute power of most fully cranked 100 watt "quad" tube amplifiers, whose output power are often well over 100 watts. Exclusive to the PRX150-Pro, are the individual input and output impedance selector switches. The user can set the attenuator's input impedance to match the amplifier's impedance and separately set the attenuator's output impedance match the speaker's impedance. This allows proper matching of mis-matched amplifier to speaker impedances. Product Highlights:
  • Proprietary SRT Technology
  • Six levels of step attenuation, plus a continuously variable attenuation control (bedroom mode)
  • 150 watt power rating
  • Independent input and output impedance selector switches (2, 4, 8, 16 ohm)
  • Features a Load setting and is equipped with a Line Out Jack and Line Out Level Control
  • Handwired in the USA
PRX150-Pro Price: 649.00
