γⅡ Series Active Line Array Back Panel: 
1  XLR signal input
Acceptable for balance and unbalance signal: Pin1: Ground, Pin2: Positive(+), Pin3: Negative(-)
2  XLR signal output
Can be connected to the signal input of another speaker
3  Protection LED (Yellow)
The LED will be lighted when there is a shortcut in the speaker or when the amplifier is overloaded.
4  Limiter LED (Red)
The LED lights which means the input signal level is too high. The incoming signal level should be turn down.
5  Signal LED ( Green)
The LED will be lighted when there are incoming signals.
6  Level knob
This knob is used for adjusting the volume. For louder sound, please turn it clockwise. For lower sound, please turn it anti-clockwise.
7  Voltage selector
AC115V or AC220V can be selected by using this switch. Please select your local electricity power supply voltage before connection.
8  Fuse jack (with fuse)
If the voltage selected is 115V, T20A/250V fuse should be used. If the voltage selected is 230V, T10A/250V fuse should be used. Please check whether the fuse can match with local electricity power supply voltage before connection.
9  Power switch
On/off power switch for the amplifier. When it is set to ON, the amplifier is powered up. When it is set to OFF, the amplifier is powered off.
10  Power on LED (Blue)
This blue LED illuminates as an indication that the amplifier is powered up.
11  Power input jack
115V/60Hz or 230V/50Hz can be selected for power input. Please mind that different fuse should be used for different voltages. For detail information, please refer to 8. Check whether the fuse can match with local electricity supply voltage before power on the unit.
12  Power output jack
This jack is used for linking another cells. The caution is the same as above.
13  Cooling fans
14  Ventilation gaps
The ventilation gaps can not be blocked on any occasions

 γⅡ Series Active Line Array Rigging Demonstration :

In order to let γ II series active line array to achieve fast rigging, we consider the rigging system as an important part. After repeated tests, we make out Biema proprietary rigging system, which has been approved by audio experts and users. Therefore, it would be worthwhile for us to introduce our Biema proprietary rigging system.
 Step 1: Move the line array cell out of the bin.(FIG 1)
 Step 2: Pull out the rigging pin in the front side and the cell tongue will spring out.(FIG 2)
 Step 3: Move the cell under the suspension frame.(FIG 3)

 Step 4: Set the hold of the front cell tongue in line with the hole of the suspension frame then insert the rigging pin into both holes to connect them.(FIG 4)
 Step 5: Pull out the rigging tongue at the back of the cell and lean the suspension frame clockwise until the hole of the frame be in line with the hole of the tongue. (FIG 5)

 Step 6: Insert the rigging pin into both holes By now the first cell have been fully connected. (The angle of the cell is 0°)(FIG 6)
 Step 7: Raise the suspension frame up about 500.00mm. Then move another cell from the cell bin and set it under the first cell.(FIG 7)

 Step 8: Put out the front tongue of the second cell andmake its hole in line with the front rigging hole of the first cell. Then insert the pin into the holes.
Insert the sliding bar at the back of the first cell into the metal gap at the back of the first cell Set the wanted connect holes into a line and insert the rigging pin. Please be minded that there are 7 holes in the metal at each side of the metal gap. (FIG 8)
 The first hole is the fix point and the second to the sixth holes stand for different angles 0°- 8°for choosing the desired spread angle of the line array just as the picture below shows. And the seventh hole is also 8°, but it stands for the fixed spread angle.(FIG 9)
 Step 9: Repeat the above step 6&7 to rig the rest cells (altogether 12 cells) until the whole array is rigging up. (The vertical angle can be adjusted to different venues. The biggest angle can reach to 88°)(FIG 10)
