Khadas Tone 2 Pro Launch, Technical Specifications, and More


After the much-anticipated wait, Khadas officially launched their latest Hi-Fi DAC, Tone 2 Pro

on December 16th. It is an ultra-slim desktop DAC that features a high-end ES9038Q2M DAC chip from Sabre technologies along with four high-performance OPA1612 Operational Amplifiers. This unit is fully up to date with MQA decoding support to offer a high-quality audio experience. However, the highlight of Tone 2 Pro is the Balanced RCA plugs that have three layers to provide better connectivity and functionality while maintaining their compact size.

Just before the launch of Khadas Tone 2 Pro, the company released all its technical parameters; let’s check them out.Khadas Tone 2 Pro-2

High-Grade Output

Tone 2 Pro has a distortion rate of around 0.000126% (Bal RCA) /0.000158% (4.4mm) and low noise levels of less than 4.2uVrms to offer superior sound quality. One can expect a crisp output with ultra-low distortion and a pitch dark, noise-free background in their audio.Khadas Tone 2 Pro-3


Compatible Gears

Tone 2 Pro has 4.4mm and 3.5mm output ports with 2.4Ω and 1.2Ω super-low output impedance. It can be conveniently paired with sensitive IEMs or headphones without facing any issues.Khadas Tone 2 Pro-4

Sturdy Built

Each part of Tone 2 Prois made using high-grade materials to offer durability. Its volume knob and casing are constructed from aircraft-grade aluminum, while the bottom cover is built from ABS plastic and polycarbonate. With a silicone footpad, this unit retains its position and prevents scratching the surface. This Hi-Fi DAC comes in 3 colors- Black, Red, Blue.Khadas Tone 2 Pro-6
