SUPPORTS IPHONE, IPAD, WINDOWS, LINUX, AND OS X

C5D is built for portable users who demand maximum audio quality, exceptionally low noise, sufficient output power, and a super fine volume control to handle sensitive headphones and IEMs

Features

PERFECT CHANNEL BALANCE

Digital stepped attenuation with zero-crossing detection and 1dB attenuation steps provide smooth volume adjustment at all volume levels, even with sensitive IEMs.

DUAL LDO REGULATION

High performance audio starts with clean power. Supply rails are filtered by impressive TPS7A4700 and TPS7A3301 regulators to achieve ultra low supply noise at a constant output voltage of +/-7V.

SMART USB CHARGING

Powered by a large 1200mAh Li-Ion battery, C5D quickly charges from any USB port (computer, tablet charger, cell phone charger, etc.). A single LED indicates battery status: solid green while on, blinking while battery is low, or blue while charging.

CONFIGURABLE SOUND

C5D features dual gain levels and a multi-position bass boost toggle for highly customizable sound.

LOW JITTER

C5D's asynchronous PCM5102A DAC operates with ultra low jitter, symmetrical pairs measuring below -112dB.

LOW OUTPUT IMPEDANCE

C5D's extremely low output impedance of 0.62 ohms ensures natural frequency response with all headphones.
