Kurzweil KDFX Installation

Kurzweil KDFX Installation

As noted above, Kurzweil’s KDFX option is shipping and lots of people are starting to ask questions about installability. Well, we have good news and bad news: The bad news is that in order to install a KDFX into your K2500 you may need modifications to the motherboard. The exact modifications required will depend upon which revision board you have, which in this case, cannot reliably be determined from your serial number. The modifications can be anything from minor jumper changes to fairly intensive rebuilding. The good news is that these modifications are covered under the Kurzweil one-year warranty (machines outside of the warranty period are not covered). The really good news is that we are equipped to do all of these modifications, so when the time comes for you to upgrade, just send your machine to us and let us take care of everything. Our service technicians will not only get your KDFX installed and working properly, but they will also give the whole machine a once over and make sure everything is up to snuff. For those of you whose machines are no longer under warranty, it is probably a good time to get them in for a check-up anyway. This minor inconvenience is a small price to pay for the incredible effects in the KDFX.

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.
