Audibly Perfect Channel Balance
Digital stepped attenuation with zero-crossing detection and 1dB attenuation steps supply smooth volume change at all volume levels, even with sensitive IEMs.
DC Coupled Signal Path
C5 uses a purely resistive signal course. Thin film, 0.1 % tolerance resistors make sure low noise and high channel precision.
Dual LDO Power Policy
High performance audio starts with clean power. Supply rails are filtered by outstanding TPS7A4700 and TPS7A3301 regulators to achieve ultra low supply noise at a constant output voltage of+/ -7 V.
Smart USB Charging
Powered by a huge 1200mAh Li-Ion battery, C5 quickly charges from any USB port (computer, tablet charger, cell phone charger, and so on). A single LED indicates battery status: strong green while on, blinking while battery is low, or blue while charging.
