سیٹ اپ

1. جگہ کا تعین: پوزیشن amplifier in a well-ventilated area, away from direct heat sources. Ensure it is securely mounted if rack-mounted.
2. بجلی بند: یقینی بنائیں amplifier's power switch is in the OFF position before making any connections.
3. ان پٹ کنکشنز: اپنے آڈیو سورس کو مربوط کریں (مکسر، پریamplifier) to the XLR or 1/4" TRS input connectors on the rear panel for Channel 1 and Channel 2.
4. آؤٹ پٹ رابطے: Connect your loudspeakers to the appropriate output connectors (Speakon or binding posts). Ensure correct polarity (+ to +, - to -).
5. موڈ کا انتخاب: Set the MODE switch on the rear panel to STEREO for two separate channels, NORMAL for dual mono, or BRIDGE for mono operation with increased power. Refer to your speaker impedance for bridge mode compatibility.
6. کم کٹ فلٹر: If desired, engage the low-cut filter switches to remove unwanted low frequencies.
7. پاور کنکشن: Connect the supplied AC power cable to the amplifier's AC inlet and then to a grounded power outlet.

آپریٹنگ

1. ابتدائی پاور آن: Turn on your audio source first, then switch the amplifier's power to ON.
2. والیوم ایڈجسٹمنٹ: Start with the input level controls on the front panel set to minimum. Gradually increase them to achieve the desired output volume.
3. نگرانی کے اشارے: Observe the SIGNAL LEDs to ensure a healthy input signal. The LIMITER LEDs should only flash occasionally during peak signals. If they are constantly lit, reduce the input level to prevent distortion and potential speaker damage.
4. بجلی بند: ختم ہونے پر، بند کر دیں amplifier first, then your audio source.

دیکھ بھال
