Limiter setup
This series of amplifiers are designed with built-in limiters. The limiter has two optional modes
to choose from (all channels share one selector switch).
In this mode, the maximum output signal of the amplifier will be limited
to a state with a distortion of about 10%. This mode is suitable for
applications that require a broader dynamic range and are not very
sensitive to distortion, such as driving a high-power subwoofer. In this mode, even when the
input signal is much higher than the rated sensitivity, the distortion of the amplifier output can
still be guaranteed to be about 10%.
In this mode, the maximum output signal of the amplifier will be limited to a state where it will
hardly be clipped. Even when the input signal is much higher than the rated sensitivity, the
sound quality of the amplifier output will still be flawless. Therefore, it is
recommended that you set the limiter to this mode in most applications.
Input sensitivity setup
This series of amplifiers have three Input sensitivity for option (all channels share one selector
switch)
In this mode, when the volume knob on the panel is turned to its maximum position, input a signal
of 0.775V (0dBu), and the amplifier is just close to the rated power. This mode is
suitable for use with preamplifiers with 0dBu level output indications, and the
preamplifier can be easily adjusted so that the different types of amplifiers
are close to the rated power output.
Note: If the volume knob is turning to the maximum position in this mode, the
gain for the high power amplifier will be larger.
Note: Input the same size signal in this mode, the amplifier with higher rated
power will have a larger power output.
Note: Compared to the other two modes, the amplifier is more prone to overload clipping in this
mode.
Note: Compared to the other two modes, the noise generated by the preamplifier will be more
amplified in this mode.
