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.
C5D is a high-performance portable headphone amplifier featuring digital volume control, multi-position bass boost, dual gain, and asynchronous digital-to-analog conversion compatible with iPad, iPhone, and all UAC1 compatible operating systems.
Digital stepped attenuation with zero-crossing detection and 1dB attenuation steps provide smooth volume adjustment at all volume levels, even with sensitive IEMs.
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.
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.
C5D features dual gain levels and a multi-position bass boost toggle for highly customizable sound.
C5D's asynchronous PCM5102A DAC operates with ultra low jitter, symmetrical pairs measuring below -112dB.
C5D's extremely low output impedance of 0.62 ohms ensures natural frequency response with all headphones.
