Frequently Asked Questions - USB 7007 US Blaster

How to turn on the USB 7007?

Connect the built-in battery or external power supply. The device turns on automatically. Use the switch on the front panel if present.

What is the battery life?

The battery life is at least 12 hours in continuous operation with a new 9V battery.

How to connect microphones or instruments?

Connect your sources to the unbalanced inputs (6.35 mm jack) of channels 1 to 4. Adjust the volume of each channel with the corresponding potentiometers.

Can I use the device in stereo?

Yes, the device has a stereo/mono switch. In stereo position, the left and right outputs are independent.

How to adjust the master volume?

Use the main volume potentiometer on the front panel. Each channel also has an individual adjustment.

What to do if sound distorts?

Check that input levels are not too high. Reduce the gain of each channel or the main volume. Make sure the battery is not weak.

How to recharge the built-in battery?

The standard 9V battery is not rechargeable. Replace it with a new one. Some versions may accept a rechargeable battery, check the polarity.

What are the output specifications?

The balanced outputs deliver a maximum signal of 16 dB. The output impedance is suitable for connection to speakers or mixing desks.

The device makes background noise, what to do?

Check cables and connections. Move the device away from electromagnetic interference sources. The signal-to-noise ratio is ≥80 dB, so normally very low.

Where to find the rating plate?

It is located on the rear panel, near the external power supply socket. It indicates the required voltage and polarity.
