LO means that the output is switched to the rear panel, and the volume knob can not adjust the volume. At this time, there is no sound from the headphone port on the front panel.

PRE means that the output is switched to the rear panel, and the volume knob can adjust the volume. At this time, there is no sound from the headphone port on the front panel.

【Power Button/Multifunction Button】

Short press, the indicator light goes off, enters mute mode, all output ports of K9 AKM stop output, at this time, turn the volume knob to restore the sound.

Why don't the output switch and gain switch respond immediately after switching?

In order to prevent the user from accidentally operating incorrectly or being unable to adjust to the required position at once, the output switch and gain switch have a delayed response setting. The system will only respond after the user stops the operation to avoid frequent response switching.

There are three headphone jacks on the front panel. Which one has the best sound quality?

Theoretically speaking, the XLR4 balance port is not much different from the 4.4 balance port. It will be more balanced and have greater thrust than the 6.35mm one.

Different headphone jacks will have different tastes when used with different headphones. There is no absolute distinction between good and bad sound quality. It is recommended to compare and listen to it in person.

Relevant suggestions when connecting K9 AKM to speakers:

• Generally, when connecting a power amplifier or active speaker, first turn down the sound of the power amplifier or active speaker, and then gradually turn it up after the connection is completed to avoid popping sounds.

• The volume in DAC mode cannot be adjusted and is the maximum. If you use the DAC function, be sure to turn down the sound of the power amplifier or active speaker first, and then gradually turn it up after the connections are made to avoid popping sounds.

• When connected to a speaker whose volume cannot be adjusted, it is recommended that the K9 AKM be adjusted to the PRE output;
