Product Information
Specification

Portable Amplifier M3 is the one which applies low-voltage op-amps. The paralleled output design can lower the overall output impedance and double the output current for driving the in-ear monitors well. The soul of this amplifier – 16340 (RCR123A) Li-ion battery has low internal resistance, comparing typical Li-polymer batteries, for stronger dynamics and higher analytical character.

As the unbalanced volume level between L & R channels of most of amplifiers is not acceptable for music enjoyment, we have introduced Alps RK097 series potentiometers, made in Japan, for all of our portable amplifiers. Apart from that, all of the components in amplifier section are audio-graded such as 718 RJ24 0.1% high precision resistors, Wima MKS2 film capacitors, Elna Silmic II electrolytic capacitors and Panasonic FM electrolytic capacitors.

Among all the low-voltage op-amps we have tested, Texas Instruments OPA2350, Analog Devices AD8606 & AD8616 are applied to this amplifiers to enhance the clarity of the audio signal output.
