Setup Guide
Follow these steps to set up your PROZOR 2x2 USB Audio Interface:
- Connect to Computer: Use the provided USB 2.0 cable to connect the interface to an available USB port on your computer. The device is driver-free for most operating systems (Windows, macOS).
- Power On: The device will typically power on automatically via the USB connection. The PWR indicator on the front panel will illuminate. If additional power is needed, connect a 5V DC power adapter (not included) to the DC 5V IN port.
- Connect Input Devices:
- Microphones: Connect your microphone to INPUT 1 or INPUT 2 using an XLR cable. If using a condenser microphone, activate the +48V phantom power switch on the front panel and ensure the rear +48V POWER switch is ON.
- Guitars/Bass: Connect your instrument to INPUT 1 using a 1/4-inch TS cable. Engage the HI-Z switch for optimal impedance matching.
- Line-Level Instruments: Connect keyboards, drum machines, or other line-level devices to INPUT 1 or INPUT 2 using 1/4-inch TRS cables, or use the RCA IN jacks for stereo line-level sources.
Figure 3: Input Connection Examples
This image illustrates how to connect various instruments like guitars, keyboards, microphones, and headphones to the audio interface. - Connect Output Devices:
- Studio Monitors/Speakers: Connect your active studio monitors to the MAIN OUTPUTS (1/L, 2/R) on the rear panel using 1/4-inch TRS cables.
- Headphones: Connect your headphones to the PHONES jack on the front panel.
- External Amplifiers/Recorders: Use the RCA OUT jacks for connecting to other audio equipment.
- Computer Audio Settings:
Once connected, your computer should recognize the PROZOR 2x2 USB Audio Interface as an audio device. You may need to select it as the default input and output device in your operating system's sound settings and within your Digital Audio Workstation (DAW) software.
- Windows: Go to Sound Settings > Playback/Recording devices and select "USB Audio Device" or similar.
- macOS: Go to System Preferences > Sound > Input/Output and select the interface.
Operating Instructions
The PROZOR 2x2 USB Audio Interface offers high-quality audio conversion at 24-bit/192 kHz, ensuring your recordings are clear and detailed.

Input Level Adjustment:
Use the GAIN 1 and GAIN 2 knobs to set the input level for your connected microphones or instruments. Observe the SIG and PEAK indicators:
- The SIG (green) light indicates that an audio signal is present.
- The PEAK (red) light indicates that the input signal is too strong and is clipping. Reduce the GAIN until the PEAK light no longer illuminates, even during the loudest parts of your performance.
Phantom Power (+48V):
If you are using a condenser microphone, ensure both the rear +48V POWER switch and the front panel 48V button are engaged. This supplies the necessary power to the microphone. Always connect the microphone before activating phantom power, and deactivate it before disconnecting.
Direct Monitoring (MIX-DAW):
The MIX-DAW knob allows you to blend the direct input signal (MIX) with the playback signal from your computer (DAW). This is useful for monitoring your performance with zero latency. Turn the knob towards "MIX" to hear more of your live input, and towards "DAW" to hear more of your computer's playback.
Output Volume Control:
- The OUTPUT knob controls the volume of the main outputs (MAIN OUTPUTS and RCA OUT).
- The PHONES knob controls the volume of the headphone output.

HI-Z Switch:
When connecting a passive guitar or bass directly to Input 1, engage the HI-Z switch. This optimizes the input impedance for these instruments, ensuring proper tone and signal transfer.
MONO Switch:
The MONO switch combines the stereo input signals into a single mono signal. This can be useful for certain recording scenarios or when monitoring a stereo source in mono.
Loopback Function:
The LOOP BACK button (located near the MIX-DAW knob) allows you to route the computer's playback audio back into the interface's input. This is useful for recording computer audio, live streaming, or podcasting where you need to capture both your microphone and system sounds simultaneously.
Maintenance
Proper maintenance ensures the longevity and optimal performance of your PROZOR 2x2 USB Audio Interface:
