※
Caution: When installing the system, ensure that the total impedance of the speaker does not fall below
the regulated impedance (4Ω, 8Ω) under all circumstances. otherwise, it may lead to overloading and
cause the system to fail.
STEREO MODE
The device produces the input signal from each channel independently. It produces the input signal from
CH1 through CH1, and the input signal from CH2 through CH2. In sTereo mode, you can control the
volume of each channel independently.
BRIDGED MODE
You can use this mode when you want to tie CH1 and CH2 together to produce a larger sound than you can
in sTereo mode. If you connect the speaker in BrIDGeD mode, as shown above, you can double the input
signal of CH1.
※
Caution
1. In BrIDGeD mode, please input through CH1 or CH3 only. The device can double the input signal
through CH1 or CH3 only, therefore make sure not to use CH2 or CH4.
2. When you connect the speaker in BrIDGeD mode, use PIn 1(+) and PIn 2(+) from the 4 Pole speaker
Connector for CH1 or CH3. (Please refer to the image above.)
3. Turn the volume for CH2 or CH4 all the way down, then control the volume for CH1 or CH3.
4. BrIDGeD mode supports 4Ω, 8Ω only.
6. Xlr InPUT/lInK Terminal
XLR INPUT TERMINAL
An Input Terminal used when connecting the output of a preamplifier or audio mixer to this device. It
features an Xlr (female) jack. When using the Xlr Input Terminal, please use a balanced jack. If you use
an unbalanced jack, it may have a significant impact on cable noise. Therefore, use unbalanced jacks
only when devices are grouped closely together. If using a balanced jack in an unbalanced manner,
please refer to the following image to connect.
