Make all initial connections with all the equipment powered off, and ensure that all the main volume controls are turned
completely down.
-. For Passive Full-range Speakers
1). Connect one side of the 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 speaker cabinet.
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 using, turn off your stereo power amplifier first, then the mixer.

-. For Active Speaker Cabinets
1). Connect one side of the signal cable at your audio mixer into output left /right (with Stereo-Jack or XLR) and
the other side of the cable into the line input (COMBO) of your active speaker cabinet (with Stereo-Jack or
XLR).
2). Connect the power cord to mains.
3). Turn on your mixer first, then the active speaker cabinets.
4). Turn up the volume control of the active speaker cabinets.

The AES 2 - 1984 Standard specification by Audio Engineering Society, is representative and commonly used for the measure in
Professional Sound Reinforcement. It is defined as the square of the RMS voltage generated with a pre-defined and band-passed
Pink Noise Signal, applied continuously for 2 hours, on the assembled speaker cabinet.
In this way, the declared power of ALTO passive speaker cabinet, is comparable to the RMS voltage value, measured on the
equivalent power amplifier for the same value of impedance.
