Product Information

As benefited from modern surface-mount technology, the size of an amplifier can be smaller with large amount of components. Portable amplifier M3HVs is designed based on portable amplifier M3HV with a slim enclosure and ±12V with real grounding power output. The tri-paralleled discrete buffer design can enhance the overall performance of an amplifier output, especially in dynamics, with using in-ear monitors.

Alps RK097 series potentiometers, made in Japan, are introduced for all of our portable amplifiers. We have selected TK Jovial Audio UTSJ electrolytic capacitors as the power output capacitors for the premium-graded music enjoyment.

There are 3 options of the op-amps used for amplifying stage – Texas Instruments OPA627AU and Analog Devices AD8610ARZ. A pair of AD8610ARZ shows ultra-high analytical character whereas a pair of OPA627AU performs high dynamics. The op-amps in amplifying stage are not changeable due to its limited thickness.
