Performance

CMA18 Portable incorporates x4 sets of patented PCT-class current-mode SiP chips, each with a peak power of up to 5W and peak current of 2A, delivering robust driving power. Gain settings, coupled with high-energy current-mode amplifier technology, ensure powerful and flexible performance.

The latest XMOS XU316 platform combined with the AK4493 DAC chip supports HD D/A converting up to PCM768/DSD512. Four sets of self-developed current-mode pCT patented SiP chips, CC630/CA630, ensure the best power and lowest power consumption in the industry, couple with 4.4mm headphone output and high/low gain mode switching, unlocking the full potential of all IEMs and top-tier over-ear headphones.

Analog Input Function

The CMA18 Portable has two stereo line-in inputs: 3.5mm and 4.4mm. They can be connected to any audio equipment that has line-out analogy outputs, including turntable systems, pre-amps, mixing consoles, and more. Once connected the CMA18 Portable is capable of functioning as an external lossless, high-performance analog-to-digital interface for either of these inputs.
