Hardware Setup: Audio Interface
1) Connect mains power into the external PSU supplied in Camden
EC1’s packaging and connect the Power Connector into Camden
EC1’s Power Inlet [8].
2) Connect the Preamp Output [3] of Camden EC1 to an available line
input on the Audio Interface. Use either Camden EC1’s balanced ¼”
jack or XLR outputs depending on your audio interface’s
connections.
Note:
If your audio interface has a low max input level, engage
the PAD Switch [4] to reduce the output level of Camden
EC1.
3) Power On Camden EC1 using a brief tap of the Power button. Then
Power On your Audio Interface.
Connect mic/line/hi-z sources to Camden EC1’s preamp input, apply Gain
and your desired Mojo setting, and now the preamp signal will be sent out
from Camden EC1 and directly into the Audio Interface’s inputs for recording.

Hardware Setup: Using C.A.S.T.
This hardware setup diagram will get Camden EC1 connected within a
C.A.S.T. enabled system alongside a 500R8/500ADAT:
1. Connect mains power into the external PSU supplied in Camden
EC1’s packaging and connect the Power Connector into Camden
EC1’s Power Inlet [8].
2. Connect Camden EC1’s C.A.S.T. Output [6] to a C.A.S.T. Input on
500R8/500ADAT using a shielded Cat 5e, Cat 6, or Cat 7 cable.
3. Power On Camden EC1, followed by 500R8/500ADAT and other
downstream equipment.
Connect mic/line sources to Camden EC1, and now the Preamp Output will
be sent from Camden EC1 and directly into 500R8’s slots ready for further
processing and recording.
At the same time, the Aux Mix created on 500R8/500ADAT is sent down
C.A.S.T., into Camden EC1, and into Camden EC1’s Aux Headphone output.
