When using a microphone with the Marshall AS50R amplifier, feedback can occur due to various reasons. Here are some possible causes and solutions to address the feedback issue: 1. Positioning: Ensure that the microphone is positioned correctly. Avoid placing it too close to the speakers or in a position where it picks up sound from the amplifier. Adjust the microphone's position to minimize the chances of feedback. 2. Volume levels: Check the volume levels of the microphone and the amplifier. If the microphone volume is set too high, it can cause feedback. Reduce the microphone volume and adjust the amplifier's volume accordingly to find the optimal balance. 3. Notch Filter: The AS50R amplifier features a frequency controllable Notch Filter. Use this control to identify and reduce frequencies that are causing feedback. Adjust the Notch Filter to target the specific frequencies where feedback occurs. 4. Phase Switch: The AS50R amplifier also includes a Phase switch. Experiment with different positions of the Phase switch to find the setting that minimizes feedback. By following these steps, you can troubleshoot and address the feedback issue when using a microphone with the Marshall AS50R amplifier, ensuring a clear and uninterrupted sound experience.
The purpose of the phase switch on the Marshall AS50R amplifier is to help control and eliminate feedback. Here's a concise explanation of its function: 1. Feedback: Feedback occurs when sound from the amplifier is picked up by the microphone and re-amplified, creating a loop that results in a high-pitched squeal or howling sound. 2. Phase Switch: The phase switch on the AS50R amplifier allows you to change the phase relationship between the amplifier's output and the microphone's input. 3. Feedback Control: By experimenting with the phase switch, you can find the setting that minimizes or eliminates feedback. In some cases, flipping the phase switch can help cancel out certain frequencies that are prone to feedback. 4. Adjusting the Switch: Try different positions of the phase switch while monitoring the sound. Find the setting that provides the clearest and most feedback-free sound. By using the phase switch on the Marshall AS50R amplifier, you can effectively control and reduce feedback, ensuring a clean and enjoyable sound experience.
The purpose of the frequency controllable notch filter on the Marshall AS50R amplifier is to help eliminate unwanted feedback and resonant frequencies. Here's a concise explanation of how to use it: 1. Locate the notch filter control on the front panel of the amplifier. It is labeled as "Notch" and is specific to each channel. 2. Turn the notch filter control to adjust the frequency at which the filter operates. This allows you to target specific frequencies that are causing feedback or unwanted resonances. 3. Start by setting the notch filter control to the halfway or 12 o'clock position. This is a good starting point to identify the problematic frequencies. 4. Gradually turn the notch filter control clockwise or counterclockwise to find the frequency that minimizes or eliminates the feedback. Listen for changes in the sound and adjust accordingly. 5. Fine-tune the notch filter by making small adjustments to the control until you achieve the desired result. Be mindful not to overcompensate and remove frequencies that are essential to your sound. By using the frequency controllable notch filter on the Marshall AS50R amplifier, you can effectively reduce feedback and improve the overall sound quality of your performance.
