C5 is built for portable users who need a small amp with USB recharging, exceptionally low noise, sufficient output power, long battery life, and most importantly, a super fine volume control to handle sensitive headphones and IEMs.
C5 is a high-performance portable headphone amplifier featuring digital volume control, bass boost, dual gain, and all-day battery run time.
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, C5 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.
C5 features dual gain levels and a powerful, 6.5dB bass boost for enjoyable listening.
C5 runs on our fully opensource Arduino firmware!
C5's purely resistive signal path delivers audibly exceptional THD, noise, and frequency response performance.
