828 does not power up.
Check the voltage switch to verify that it is set correctly. Facing the front of the 828, the voltage can be found on the right side of the unit. It is a recessed red switch, that read either “115v” or “230v”. North American users should set this switch to 115v. Other users (european, asian, etc) should set this to 230v.
If the voltage swtich is set correctly, and the 828 still fails to power up, please contact Sweetwater Technical Support or MOTU Technical Support.
MOTU has determined that the original fuse installed in the 828 can sometimes be too sensitive, and blow prematurely. MOTU will ship customers the newer, more tolerant fuse asap. This fuse is user installable, and somewhat easy to replace.
You’ll need two phillips head screwdrivers. One medium sized, and one small.
1. Unplug all connections to the 828, especially the power cable.
2. There are two screws on each side of the 828, two on the front, two medium sized screws on the back, and four small screws around the mic inputs. Simply remove all screws and slide the top of the unit off.
3. While facing the front of the 828, the fuse is on the far right of the circuit board. gently pry the fuse out (I use a small screwdriver on one of the metal ends). replace the fuse with the new fuse, and replace the top of the 828 and all of its screws.

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.
