Connection with preamplifier

For connection between the input terminals (INPUT) of this unit and the output terminals of a stereo preamplifier, always use nect the left channel and right channel output terminals of the preamplifier correctly to the LEFT (left channel) and RIGHT (right channel) INPUT terminals of this unit, respectively. terminals for cannon connectors. hook to prevent accidental disconnection during operation, it is safe.

Ultrasonic filter

This unit features the wide-band design in which the high-frequency zone extends up to

MHz. Therefore, an AM radio station or a CB radio in the neighborhood may become mixed with the input signal and sound quality. Since the mixed radio frequency is outside the audible frequency range, the user may not be aware of its presence. In such a case, the red "ultrasonic interference'' indicator illuminates to warn the user. Press the ultrasonic filter switch. The green "ultrasonic" indicator illuminates and, at the same
