DUNU DTC 800 - Portable USB DAC & Headphone Amplifier

Powerful Listening in a Pocket-Sized DAC/Amp

The DUNU DTC 800 is a portable USB DAC and headphone amplifier combining dual Cirrus Logic CS43198 DAC chips with two independent SGM8262 amplifier chips. Its compact, cyberpunk-inspired aluminum chassis brings balanced amplification and hands-on controls to your everyday listening setup.

Connect a compatible audio source, cue up a favorite album, and adjust the output to suit your earphones, from sensitive IEMs to more demanding full-sized headphones.

Dual CS43198 DAC Architecture

Two Cirrus Logic CS43198 DAC chips form a fully balanced audio architecture. Specified distortion reaches as low as 0.0002%, with a signal-to-noise ratio of up to 126dB, supporting detailed reproduction and a low-noise background. Measurement results depend on operating and test conditions.

Independent Amplification

Dual SGM8262 amplifier chips provide up to 450mW at 32Ω through the 4.4mm balanced output. This gives the DTC 800 flexibility across a range of IEMs and headphones; suitability depends on the connected headphones' impedance and sensitivity.

High and Low Output Modes

Selectable output modes let you match the amplifier to your earphones and listening level. High-output mode delivers up to 4Vrms. To switch modes, press and hold the + volume button for more than one second, then release. Lower the listening volume before changing modes.

Hardware Volume Controls and LED Indicator

Onboard volume buttons provide direct audio adjustment. A multicolor LED indicates the current sampling rate and playback format, keeping essential playback information visible at a glance.

CNC-Machined Aluminum Construction

The chassis is precision-machined from a single block of aluminum alloy and finished with a sandblasted texture. Independent LDO power supplies and active clock crystals are designed to manage power delivery, timing stability, and electrical interference for clean playback.
