3. 操作手順

The E7 3X crossover allows for precise tuning of your audio system to achieve optimal sound quality and speaker protection. Adjustments should be made incrementally and with careful listening.

クロスオーバー周波数調整:

• Front & Rear High-Pass: Use the dedicated knobs to set the high-pass frequency for your front and rear speakers. This filters out low frequencies, preventing distortion and protecting smaller speakers. The variable range is 35 - 45Hz with an -18dB/octave slope.
• サブローパス: Adjust the low-pass frequency for your subwoofer output. This ensures only low frequencies are sent to the subwoofer, maximizing bass performance. The variable range is 45 - 250Hz with an -18dB/octave slope.

低音ブーストコントロール：

The E7 3X includes a variable bass boost feature. Use the dedicated knob on the unit or the remote bass control to adjust the bass level. The bass boost is variable up to +/- 18dB at a frequency range of 40 to 120Hz. Adjust this setting to your personal preference, being mindful of potential distortion at extreme levels.
