Using condenser mics
(Phantom Power)
In general, when using condenser mics, no sound is
produced without phantom power being supplied to the mic.
The BR-1180/1180CD is capable of supplying +48 V phantom
power to condenser mics connected to the MIC 1 and 2

in response to a sound, waveforms are generated. As
these waveforms are very weak, amplification circuitry
inside the microphone may also be used to boost the
signal. Thus, phantom power is the power that makes
such waveform generation and amplification possible.
Some condenser mics can use an internal battery as the
power supply. In such cases, no phantom power supply
is necessary.
