Contact Information
1. First, turn the WATT knob on the front panel to the maximum(200W).
2. Connect the power amplifier and speaker to the corresponding interface A/B or I/O of the VU102,
and let the VU102 work in the mode of 1-IN-2-OUT or 2-IN-1-OUT.
3. Connect the power cord and VU102 will automatically turn on.
(Press the selector key on the front panel for 3 seconds or the remote control can turn off VU102.)
4. Select A/B working modes through the selection key on the front panel or remote control. If the connection mode is 1-IN-2-OUT,
you can also set the A and B to work simultaneously through remote control.
(Note: A/B parallel work mode does not support 2-IN-1-OUT mode, it will damage your amplifier.)
5. Then use the WATT knob to adjust the VU pointer in appropriate swing range.
6. When the power is off, the VU102 will disconnect the A/B and I/O ports, turn off the backlight of VU meter and all speakers will mute. In 1-IN-2-OUT mode,
if the amplifier still has audio signal output, it’s normal for the pointer of the VU meter to continue to swing. Because the VU table is a passive drive
board, it is driven to swing directly from the audio signal of the I/O port.
