8 CHANNEL CLASS-D AMPLIFIER
DXI8200
8 CHANNEL CLASS-D AMPLIFIER
Speakers can be connected to the DXI8200 using the following three mode settings. The
total load impedance of the speakers that can be connected will depend on the mode
setting. Do not use a setup that has a lower impedance than the minimum values shown
below.
STEREO mode
If the rear panel MODE switch is set to STEREO, each channel will operate independently. You
can use the front panel attenuators to adjust the attenuation for each channel independently.

Channel A
PARALLEL mode
If the rear panel MODE switch is set to PARALLEL, the input signals will be input to the adjacent
channels (A-B, C-D, E-F, G-H) as well. Either of adjacent two channels can be used as an input
connector. You can use the front panel attenuators to adjust the attenuation for each channel
independently.
BRIDGE mode
If the rear panel MODE switch is set to BRIDGE, the amplifiers will be bridged between adjacent
pairs of channels (A-B, C-D, E-F, G-H), and the IPA8200 will operate as a high-power amplifier.
Either of adjacent two channels can be used as an input connector. Use the front panel channel
A/C/E/G attenuators to adjust the attenuation.

SPECIFICATIONS
The DXI8200 amplifier has an automatic power factor correction system for a perfect main
network interface. The amplifier is a resistive load for the main network, minimizing the reactive
power and the harmonic distortion on the current. The system allows performance to be
maintained even in circumstances of varying the mains voltage.
