IDENTIFICATION

Black Soft-Touch Finish With Silver Lettering, Protective End-Cap, Leatherette Travel Pouch

NATIVE RESOLUTION

Up to 24-bit / 96kHz

OUTPUT

1.8 volts

Direct-Coupled, High output — Excellent for driving a wide range of headphones, including power-hungry, low-efficiency (~90-95dB/mW) models. In addition, DF 1.2's higher output enables a more dynamic musical presentation, with powerful lows and clean, well-extended highs. When used as a line-level device (volume set to 100%), DF 1.2's 1.8 volts provide enough power to drive all preamplifier, integrated amplifier, or receiver inputs.

MICROCONTROLLER

Texas Instruments TAS1020B

The TAS1020B (USB 1.0 and 1.1 compliant) was one of the first competent full-speed isochronous USB-controller solutions available for USB audio. At its inception (circa 2002), power consumption was far less of a concern, since the mobile devices of the time were not often used to store and play music.

DAC CHIP

ESS 9023 24-Bit

All ESS DAC chips represent outstaning performance and value.

VOLUME CONTROL

Analog Volume Control

Digitally controlled (from the host) analog volume control. With DF 1.2 connected to a PC, adjusting the system's volume control will, through proxy, control the DF 1.2's onboard volume, ensuring maximum resolution regardless of volume setting.
