Blue POD
Speakers, Microphones and Other Components
Most 4 or 8Ω speakers, 48V phantom microphones or other sound components can be used with the BluePOD system - there is no
need for a specific sound system configuration.
The BluePOD system automatically provides Acoustic Echo Cancellation (AEC) for microphone connections. This feature cannot be
disabled and does not apply to line input sources.
Phoenix style connectors are available on the back of the BluePOD Controller, with specific labels for the type of input.
There are two speaker connection ports and 4 USB ports also available on the Controller.
Caution: Do not plug in or unplug microphones while the BluePOD is powered on� Unplugging or plugging in
microphones while the device is on may damage equipment�
Line Level Source (Phoenix style connectors)
The BluePOD Controller will accept line level balanced or unbalanced audio inputs. Connect your audio source(s) to the appropriate
Phoenix style connectors. No adjustments need to be made for balanced or unbalanced inputs; this is internally detected & managed.
See illustrations for balanced and unbalanced cable configurations.

Summing an unbalanced stereo line-level source to a single mono input
If using a stereo source for an input, the stereo signal will be combined to mono, and heard in mono, on the A or B channel of the
BluePOD Controller.
The + and - Phoenix style terminals are
each tied internally to single differential amplifiers.
Proper Wiring (See yes circle):
The resistors, along with the jumper between - and ground, are necessary to allow the left and right
signals to be summed before being preamplified by the
single differential (single-ended) amplifier inside the BluePOD Controller.
