The C3 has an internal power supply, configured at the factory for either 115V or 230V. The captive power
cable is fitted with the appropriate plug for the intended region. Do not attempt to modify the plug or the
power supply. If your Gadget does not have the proper plug/voltage for your region, contact the factory to
arrange a return/replacement.
C3 is equipped with both analog and digital audio inputs and outputs. Best performance will be achieved
using the digital input and output (AES/EBU) on St RJ45 connectors. To select the DIGITAL IN
as the audio source, flip DIPswitch B to the up position.
Analog inputs and outputs are presented on both XLR and St RJ45 connectors. A convenient
ANALOG THRU is useful for daisy chaining the same source to multiple devices.
The Analog Output on the St RJ45 connector also provides ±15VDC to certain types of
connected devices. It is possible for example, to feed power and processed audio over a single CAT5
cable from this output to an Angry Audio Headphone Gizmo.
The front panel controls are straightforward. The headphone amplifier with volume control has both
6.3mm and 3.5mm jacks. The jacks are mutually exclusive.
Exercise caution with headphone volume!
It is possible to cause permanent hearing damage with excessive volume!
