The Quad 405 is a two channel power amplifier designed for domestic and professional use employing current dumping which eliminates many transistor problems. The high power output makes it suitable for use with many of today's high quality loudspeakers and provides opportunity for farther loudspeaker engineering development with less emphasis on efficiency. The external design continues the Quad tradition of practical simplicity which has won prizes and worldwide acclaim on previous models. A combination of moldings and extrusions is used to produce a unit which is strong and pleasing both to the eye and the touch. Not all loudspeakers can safely accept the full output power of the Quad 405, and the amplifier is provided with a power limiter which is fitted internally for use in such cases.
