Digital Feedback Loops
“What are the consequences (if any) in regard to the equipment when you inadvertently get into a digital loop and the equipment feeds back? Sounds like the equipment doesn’t like it, and neither do I. But it happens sometimes. I understand that the speakers are the most vulnerable link in the chain, but what about the rest of the equipment?” There isn’t much that will fry speakers faster than feedback. Besides the discomfort and potential damage to your ears, any type of speaker or headphone is by far the most at risk during feedback. The way electronics work most devices are limited by the supply voltage of their power supplies. While they may go into extreme distortion during feedback (which, by the way, is usually what destroys the speakers), they aren’t going to harm themselves. There’s always an exception somewhere, but generally electronics are not significantly harmed by feedback, though it is best to avoid it. Digital feedback loops often produce a type of feedback that is inaudible and therefore pretty harmless even to speakers.

Offer applies only to single-receipt qualifying purchases. Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
