P.A. BASICS
A mixing board is actually a very simple device that takes the audio input signals (from the input channels) and “mixes”
them to the outputs. The mixing board controls will typically enable the user to blend the input channel signal levels, affect
their tone, and adjust each channel’s reverb level. The signal is then fed from the mixing board to the amplifiers and onto
the speakers. PRX915/918XLF is a self-contained PA system, which includes a mixing board, amplifiers, and speakers.
GETTING ACQUAINTED WITH PRX900 SERIES SUBWOOFER
The powered mixer section of the PRX915/918XLF Series Subwoofers houses the mixing board and power amplifier. Here,
line level sources like powered speakers and external mixers can be connected.
