Frequently Asked Questions
1. Why is the sound coming out of the MC101 so low until the volume s adjusted to a higher level?
The MC10T's volume control adopts a Taper A potentiometer that increases volume logarithmically. The increase in sound is slight in the early stage but increases significantly in the latter stage. Human ears perceive sound logarithmicly rather than linearly, 5o this design can better match the characteristics of human hearing to provide a more natural and intuitive volume control.
2. Why is there no sound output when the product is connected and music is played upon startup?
A. The amplifier is not powered on, please check whether the mode indicator is on; 8. The volume of the amplifer is too small, please tur the volume knob clockwise and adjust it to the right level; C. The audio cable is connected incorrectly, please reconnect it according to the steps in the instruction manual; D. The audio source is not playing or muted, please check the audio source equipment
3. Why is the power indicator light very dim or flashing constantly after powering on?
It is normal for the blue light to biink in Bluetooth mode when it is waiting to be connected, and the blue light wil stay steady when successfully connected; The blinking power indicator in RGA mode may be due to insufficient power supply voltage, please make sure you are using the supplied 24V/4.5A power supply.
4. What s the purpose of the pre-out interface?
