• GAUTIS: Adjusts the input sensitivity for the connected device. Use this to achieve a healthy signal level without clipping.
• EQ (ekvalaizeris): The mono channel (Mic/Line 1) has a 2-band EQ (HIGH and LOW) to shape the tone of the input signal.
• PAN/BAL: The PAN control (mono channel) adjusts the signal's position in the stereo field (left to right). The BAL (balance) control (stereo channels) adjusts the relative level of the left and right signals.
• LYGIS: Controls the overall output level of the individual channel to the main mix.
• CLIP LED: Šviečia, kai įvesties signalas yra per stiprus, o tai rodo galimą iškraipymą. Jei šis LED dažnai šviečia, sumažinkite STIPRINIMĄ.
