Clean and stable power source The toroidal transformer provides an efficient and stable power source for amplifiers, preamplifiers and other musical equipment. power conversion efficiency Low standby power consumption and minimal interference ensure clean power performance and reduced energy use. Durable construction steel bracket and a thermal conductivity layer promote heat dissipation, delivering stable support with low vibration. Versatile output options The output includes dual 28V for the amplifier rear stage, dual 12V for the preamp, and a single 12V for the control protector, totaling approximately 200W. Use scenarios Recording studio or project room Power a main amplifier at 28V for the rear stage and a 12V rail for the preamplifier, with an additional 12V supply for the control protector. The stable, efficient supply helps minimize noise and hum, aiding clarity in signal paths. Live rehearsal or small venue setup Simultaneously power a guitar/bass amplifier, a preamp, and control equipment from the same unit. The dual 28V and dual 12V rails provide dedicated, matched supplies to reduce interference and maintain consistent performance during performances. Home audio or compact theater system Supply the amplifier and audio processing components with clean, stable power. The configurable 28V and 12V outputs support multiple components while keeping overall power usage efficient.
