Operation Guide

1. Connect the USB-C power cable to the DC input port on the LC30 and insert a pair of AAA batteries into the remote control;
2. Use speaker cables to connect your speakers to the speaker output terminals on the LC30:
3. Connect your amplifier to the amplifier input terminals on the LC30 using speaker cables;
4. Turn the VU knob fully counterclockwise and then gently short-press the power button to turn on the device.

Precautions

1. The LC30 is capable of connecting to up to two amplifiers and two pairs of speakers. However, it is designed to operate with only one amplifier and one pair of speakers at a time;
2. The VU meter pointer sensitivity knob should be adjusted slowly to find the appropriate setting. Rapidly turning the knob to the maximum may result in damage to the VU meter;
3. The USB port is for power supply only and does not support data transfer functions.

Frequently Asked Questions

1. Why is only one VU meter's pointer swinging?

The LC30's VU meters independently monitor the left and right audio channels. If the pointer on the left VU meter is stationary, it may indicate an issue with the left channel of your system. Please check your setup. The same applies to the right side.

2. Why doesn't the VU meter light up after powering on?

The VU meter light may not be activated. You can press the power/brightness control button on the unit or use the remote control to increase the VU meter's brightness.

3. Can I use two pairs of speakers simultaneously?

The LC30 is designed to switch between two sets of speakers and does not support simultaneous output to both pairs.
