4. Istruzioni per l'uso
Understanding the controls of your BY-AM4 will help you achieve optimal audio quality.
4.1. Regolazione del guadagno in ingresso
Utilizzare il GUADAGNO 1 E GUADAGNO 2 knobs to adjust the input level for each connected microphone or instrument. Aim for a strong signal without clipping (distortion). Most DAWs will have input meters to help you monitor levels.
4.2. Alimentazione Phantom (48 V)
Premere il tasto 48V button to supply +48V phantom power to condenser microphones. Ensure your microphone requires phantom power before activating this feature. Dynamic microphones do not require phantom power.
4.3. Funzione di riduzione del rumore
Attivare il DRENAGGIO button to engage the built-in noise reduction. This can help reduce background hiss or hum, especially in noisy environments. Experiment with this feature to find the optimal setting for your recording.
4.4. Monitoraggio diretto
Premere il tasto DIRETTO button to enable direct monitoring. This allows you to hear your input signal directly through the interface's outputs (headphones, line outputs) with zero latency, bypassing your computer's processing. This is crucial for real-time performance and recording.
4.5. Loopback Function
IL RITORNO function allows you to record audio playing on your computer (e.g., from YouTube, Spotify, or a video game) simultaneously with your microphone or instrument input. This is particularly useful for live streaming, podcasting, or creating content that combines multiple audio sources.
4.6. Connettività MIDI
The BY-AM4 includes MIDI IN/OUT ports. Connect your MIDI keyboard, controller, or other MIDI devices to these ports. Press the Midi-Film button to ensure MIDI functionality is active. Your DAW will recognize the BY-AM4 as a MIDI interface, allowing you to send and receive MIDI data.
4.7. Controllo del volume di uscita
Regolare il TENERE SOTTO CONTROLLO knob to control the overall output volume for your headphones and line outputs. Always start with a low volume and gradually increase it to a comfortable listening level.
