Warm tips
- USB power only supports DC 5V single voltage and a current of at least 1A; when the current is not enough, the backlight of VU meter will blink if you switch the channel, and it’s not recommended to use a fast charger or dual voltage power.
- If the A/B ports are not selected, it will automatically switch to build-in load and connect to the L/R channel of amplifier.
- When VU102 is powered off, A/B will disconnect from the I/O at the same time and enter the mute mode. A/B ports will switch to build-in load.
- There will be relatively loud sound when switching A / B channel, this is normal.
- For faster and safer delivery, the remote control without battery（2*AAA）, also without DC5V power adapter, please prepare them by yourself.
Introduction
VU102 is a VU meter and amplifier/speaker selector, convenient to compare the
sound quality of 2 pairs of different speakers or 2PCS power amplifiers
and enjoy the visual experience with the VU meter. Each channel can pass
through power up to 200W, fully isolated design for all channels, and a build-
in protection load. Equipped with remote control, all setting support power
loss memory, convenient to quickly set the best working state. Suitable for
all types of amplifiers such as digital amplifiers (BTL, Class A, Class B,
Class D ) and tube amplifiers. Proper size with simple appearance, fashionable

Step for use
-
First, turn the WATT knob on the front panel to the maximum(200W).
-
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.
-
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.)
-
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.) -
Then use the WATT knob to adjust the VU pointer in appropriate swing range.
-
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.
