- Segwi l-istruzzjonijiet fuq l-iskrin biex tlesti l-installazzjoni tas-sewwieq.
- For Mac OS X (10.4 and above), the native CoreAudio USB audio driver is supported, and no additional driver installation is required. A Mac control panel may be available for advanced settings.
4.2 Konnessjoni ma' PC/Mac
The U22XT is USB bus-powered, meaning it draws power directly from your computer via the USB connection.
- Kun żgur li l-kompjuter tiegħek huwa mħaddem.
- Connect one end of the provided USB cable to the USB 2.0 port on the rear of the U22XT.
- Qabbad it-tarf l-ieħor tal-kejbil USB ma 'port USB disponibbli fuq il-kompjuter tiegħek.
- The PWR LED on the front panel of the U22XT should illuminate, indicating it is receiving power.
4.3 Konnessjoni ta' Mikrofoni u Strumenti
- Mikrofonu: Connect your microphone to the XLR input on the front panel. If using a condenser microphone, press the +48V button to activate phantom power. Adjust the 'GAIN' knob for the microphone input to set the appropriate level.
- Instrument (Hi-Z): Connect your electric guitar or other high-impedance instrument to the TS (1/4") Hi-Z input on the front panel. Adjust the 'GAIN' knob for the Hi-Z input.
- Line-Level Devices: Connect line-level devices (e.g., synthesizers, media players) to the RCA inputs (Left-1, Right-2) on the rear panel.
4.4 Connecting Speakers and Headphones
- Monitors tal-Istudjo: Connect your active studio monitors to the TRS balanced outputs (Left-1, Right-2) on the rear panel using 1/4" TRS cables.
- Headphones: Connect your headphones to the 1/4" TRS headphone output on the front panel. Adjust the 'L. HEADPHONE' gain knob for headphone volume.
5. Operazzjoni
5.1 Kontroll tal-Qligħ tad-Dħul
Use the individual 'GAIN' knobs for the microphone and Hi-Z inputs to set the input level. Monitor the 'PEAK' LEDs; they should light up only occasionally on the loudest parts of your signal to avoid clipping.
5.2 Qawwa Phantom (+48V)
The +48V button activates phantom power for the XLR microphone input. This is necessary for most condenser microphones. Ensure your microphone supports phantom power before activating it. Do not activate +48V for ribbon microphones or dynamic microphones unless specified by the manufacturer.
5.3 Direct Monitoring (In/Mix/Out)
The 'IN MIX OUT' knob allows you to blend between the direct input signal (IN) and the playback signal from your computer (OUT). This is useful for monitoring your input signal with zero latency, preventing delays during recording. Turn the knob towards 'IN' to hear more of your live input, and towards 'OUT' to hear more of your computer's playback.
5.4 Master Output Volume
The large 'MASTER' knob controls the overall output volume to your connected studio monitors. Adjust this to a comfortable listening level.
5.5 Headphone Volume
The 'L. HEADPHONE' gain knob controls the volume of the headphone output independently of the master output. This allows you to set a separate monitoring level for your headphones.
6. Integrazzjoni tas-Software
The ESI U22XT comes bundled with professional audio software to enhance your recording and production workflow:
- Bitwig Studio 8-Track: A powerful and intuitive Digital Audio Workstation (DAW) for creating and arranging music. Use the provided license to activate your copy.
- inTone 2 ESI Edition from Audified: This software provides additional tools for processing and effects.
Refer to the respective software manuals for detailed instructions on their use.
7 Issolvi l-problemi
- No Power/Device Not Recognized: Ensure the USB cable is securely connected to both the U22XT and your computer. Try a different USB port or cable. Verify that the necessary drivers are installed correctly.
- Ebda Output tal-Ħoss: Check all cable connections to your speakers and headphones. Ensure the 'MASTER' and 'L. HEADPHONE' volume knobs are turned up. Verify that the U22XT is selected as the default audio output device in your computer's sound settings and your DAW.
- Ebda Sinjal ta 'Input: Check microphone/instrument connections. Ensure +48V phantom power is activated for condenser microphones. Adjust the input 'GAIN' knobs. Verify the U22XT is selected as the input device in your computer's sound settings and your DAW.
- Latency Issues: Ensure you are using the correct ASIO (Windows) or CoreAudio (Mac) drivers. Adjust the buffer size in your DAW's audio settings (lower buffer size reduces latency but requires more CPU power). Use the 'IN MIX OUT' knob for direct monitoring to bypass software latency.
- Ħoss Mgħawġ: Check input 'GAIN' levels to ensure the 'PEAK' LEDs are not constantly lit. Reduce the input gain if necessary. Ensure output levels are not too high, causing clipping at your speakers/headphones.
