_PHOEBE USER MANUAL

Rear socket supports following signals:
•
Microphone (XLR)
•
Line (XLR)
10. HiZ – instrument mode
Instrument mode – HiZ – is automatically engaged when two conditions are met:
•
Front panel mode is active.
•
TS Jack cable is inserted in the front panel TS socket.
11. +48V Phantom power!
+48 Phantom power is well known as convenient power source for condenser microphones. It is part of
most of available preamplifiers and _PHOEBE is no different. However due to different settings in internal
circuit, there are some rules on how the Phantom power is engaged/disengaged:
•
LINE gain mode will always disable Phantom power and turn it unresponsive on both front panel
and the plug-in.
•
HiZ mode will always disable Phantom power and turn it unresponsive on both front panel and the
plug-in.
•
Any change between FRONT and REAR settings will respect both above settings. That means if
REAR is set to LINE and FRONT to MICROPHONE gain level, changing FRONT to REAR will disable
Phantom power automatically.
12. OUTPUT PAD
Output PAD was designed to generate 15dB of attenuation at its maximum setting. However, as its
implementation is fully in the analog realm, nothing is perfect, and its value may vary because of following
reasons:
•
Tolerance of the resistors and limited values availability.
•
Input impedance of next unit in analog chain.
In practice maximum value of attenuation generated by PAD will be around 16-17 dB. In situations where
next unit in chain input impedance will be very low, it may cause to push that value few dB further.
