  6. questionModel 525 Stereo Amplifier Features and Specifications
    A bridgeable power amplifier that delivers stunning dynamic realism and expressive refinement. Housed in a chassis milled from a solid block of aircraft-grade aluminum, the Rowland Model 525 features a topology that is as advanced as it is efficient. From a single Model 525 in stereo mode at the ...
  7. questionModel 525 Form Factor and Power Rating
    The Model 525 Stereo Amplifier maintains the same form-factor and size as the original Model 501 Mono amplifier but offers two 250 watt channels with bridging capabilities, converting both stereo channels into a single mono channel capable of up to 950 watts of output power into an 8 ohm load.
  8. questionDoes the Model 525 utilize active power factor correction?
    Yes. The Model 525 offers active power factor correction circuitry integrated into the power supply for excellent utilization of ac mains current and reduction of ac mains harmonic currents normally generated by all high power amplifiers.
  9. questionModel 525 Signal Technology
    The Model 525 utilizes large studio grade Lundahl transformer on each channel, configured for voltage step-down, minimizes source loading and interactions while providing superior RF and EMI immunity. Other benefits include ground noise isolation and excellent common mode noise rejection (CMRR) ...
  10. questionModel 525 Chassis
    The Model 525 amplifier is machined from a single billet of 6061 aluminum which successfully minimizes micro-phonically induced micro-vibrations from any source. The curved, slightly convex faceplate, integral to the main chassis, completes the design goal of a fully monolithic chassis.
  11. questionCan the Model 525 power light be dimmed and/or switched off?
    Yes. An internal switch allows the user to dim the front panel indicator light "ring" or shut off the light altogether when the amplifier is powered on.
  12. questionIs the Model 525 stereo power amplifier a green product, and why is it important?
    Jeff Rowland is committed to help manage responsibly the finite energy resources of our planet. This is one of the many reasons why he has embraced the green technologies of switch mode power supplies and Class-D amplification in the Model 525 compact stereo power amplifier. The Model 525 enjoys ...
  13. questionIs the PC-1 PFC rectifier compatible with the Model 525 compact stereo power amplifier?
    ABSOLUTELY NOT. The Model 525 stereo amplifier utilizes built-in active power factor correction technology that could interact destructively with any external power factor correction technology. Using any external power factor correction technology with the Model 525 could result in damage to th ...

  15. questionWhy does the Model 525 stereo power amplifier employ a highly regulated switch mode power supply?
    The advanced and high speed switch mode power supply of the Model 525 monoblock power amplifier is enhanced by voltage regulation. It is nimbler, faster, more responsive, and lighter than traditional linear or toroidal power supplies. It contributes to the superior dynamics and agility of the ...
  16. questionModel 525 Switching Between Stereo and Bridge Modes
    The Model 525 can be used singly as a stereo amplifier or in tandem as a mono amplifier. The toggle switch to move between Stereo Mode and Bridge Mode is located inside the chassis requiring the removal of the bottom cover. (1) Turn Model 525 chassis upside-down on a soft non-abrasive surface. ( ...
