1. QUICK START - PASSIVE SPEAKER CABINET
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.

4. WIRE CONNECTIONS
-. For Passive Speaker Cabinets
Please use only the power connectors to make connections with other signal source equipment for the passive speaker
cabinets. The power connector has four terminals: 1+, 1-, 2+, 2-.
2-
1-
1+
2+
In our cabinets, only 1+/1- are used to connect the Speaker+/Speaker-, and 2+/2- are not used.
-. For Active Speaker Cabinets
As to these circumstances, audio connections is mostly intended for the signal flow, so, determine the wire configuration
according to your real application system and its connecting facility. Normally, you have the following choices:

5. SUSPENSION POINT
The PS series speaker cabinet also provides the suspension
points for fixed installation. How to use them?
Eyebolt
First, open the dust covers, and the next, mount the flying rings
to the suspension points (M10 1.5PH LENGTH: 30mm).
Dust Cover
For further details, please refer to the right illustration.

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.
