Audibly Perfect Channel Balance
Digital stepped attenuation with zero-crossing detection and 1dB attenuation steps provide smooth volume modification at all volume levels, even with delicate IEMs.
DC Coupled Signal Course
C5 utilizes a simply resistive signal course. Thin film, 0.1 % tolerance resistors guarantee low sound and high channel accuracy.
Dual LDO Power Policy
High efficiency audio starts with clean power. Supply rails are filtered by outstanding TPS7A4700 and TPS7A3301 regulators to accomplish ultra low supply sound 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 suggests battery status: solid green while on, blinking while battery is low, or blue while charging.
