JDS LABS C5 BLACK HEADPHONE AMPLIFIER
BRAND NEW INTACT

Audibly 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.

DC Coupled Signal Path
C5 uses a purely resistive signal path. Thin film, 0.1% tolerance resistors ensure low noise and high channel accuracy.

Dual LDO Power 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, 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.
Note: Actual color varies with lighting conditions and may differ from your screen.
