3. QUICK START - PASSIVE SPEAKER CABINETS
Passive two subwoofers and two satellite speakers. With this example, the
stereo amplifier drives both the subwoofers and the satellites. In this case we
do not call them full-range anymore because they receive a signal from the
subwoofer that is already xovered at 125 Hz. In this way, the high energetic
content of the low frequencies is limited to the subwoofer and the satellite's
woofer act like a mid-woofer.
1). Connect one side of speaker cable to the Output CHA/CHB or Binding Post
of your stereo power amplifier and the other side to the Input socket of your
subwoofer, with the second speaker cable connect the Output of the sub
-woofer to the Input of satellite.
2). Complete other connections as illustrated.
3). Turn on your mixer first, then the stereo power amplifier.
4). Turn up the volume controls of your amplifier to about 70%.
5). Use PFL function to get the proper input level for the mixer, and adjust the
Main Mix Level control to manipulate the output level.
6). After use, turn off your stereo power amplifier first, then the mixer.
