Product Overview

Front Panel

The front panel of the Peavey USB-P features the USB input port for connecting to your computer. It also includes a STEREO/MONO switch to select the desired output mode and an 'ON' indicator light to confirm power status.

Rear Panel

The rear panel provides two balanced XLR outputs (LEFT and RIGHT) for connecting to a mixer or powered speakers. These outputs are ground-lifted and transformer-isolated to prevent hum and noise.

Setup

Connecting to Your Computer

1. Connect the USB-P to an available USB port on your computer using a standard USB cable.
2. The device is a standard USB class-compliant audio device, meaning it typically does not require special drivers for most operating systems (Linux, Windows, macOS). Your computer should automatically recognize and install the necessary components.

Connecting to a Sound System

1. Connect the LEFT and RIGHT XLR outputs on the rear panel of the USB-P to the corresponding inputs on your mixer or powered speakers using balanced XLR cables.
2. Ensure your mixer or speakers are powered off before making connections to prevent damage.

Operating Instructions

Audio Playback

1. Once connected, select the "Peavey USB-P" as your audio output device in your computer's sound settings or your digital audio workstation (DAW).
2. Begin playing audio from your computer. The "ON" indicator light on the front panel will confirm the device is receiving power and operating.
3. Adjust the output volume from your computer or mixer to achieve the desired listening level. The USB-P itself does not have a volume control.

Stereo/Mono Output Selection

• Use the STEREO/MONO switch on the front panel to select between stereo and mono output modes.
• In stereo mode, audio will be sent as separate left and right channels.
• In mono mode, the left and right channels will be summed to a single mono signal and sent to both XLR outputs. This is useful for applications where a single, combined audio signal is preferred.

Troubleshooting

No Audio Output

• Check USB Connection: Ensure the USB cable is securely connected to both the USB-P and your computer.
• Verify Power: Confirm the "ON" indicator light on the USB-P is illuminated.
• Computer Sound Settings: Make sure "Peavey USB-P" is selected as the default audio output device in your computer's sound settings.
• Mixer/Speaker Connections: Double-check that the XLR cables are correctly connected to your mixer or powered speakers and that their input levels are appropriately set.

Hum or Noise in Audio

• The USB-P features transformer isolation and ground-lifted balanced outputs specifically designed to minimize hum and noise.
• Check Cables: Ensure you are using balanced XLR cables for output connections. Unbalanced cables can introduce noise.
• Power Source: If using a laptop, try running it on battery power to see if the noise is related to the laptop's power supply.
• Ground Loops: The device's design helps prevent ground loops. If noise persists, check other components in your audio chain for potential ground loop issues.
