Four Channels of PCIe Perfection

Get to know them!

If you're involved in demanding professional broadcast or recording, the Lynx E44 is made for you. Built upon the legacy of the acclaimed LynxONE and LynxTWO cards, E series audio interfaces go further to deliver the highest A/D and D/A conversion performance ever in a PCI Express card - even eclipsing that of the Lynx Aurora. The E44 employs state-of-the-art design methodologies to achieve high performance levels. Components are painstakingly selected to provide vanishingly low noise and distortion. The compact circuit topologies are engineered to cancel external noise pickup. Capacitors with solid dielectrics are used for high reliability and long life. Sweetwater engineers rely on Lynx products day-in and day-out. You can, too.

Solid Lynx engineering

Like all Lynx products, the Lynx E44 is engineered to perfection. One example would be the PCB layout, which emphasizes exacting component placement and trace routing, in addition to extensive use of copper planes for shielding and power distribution. With the PCI Express bus, power is a particular challenge due to the lack of the negative supply rail required to power analog amplifier stages. To overcome this, the E series employs a unique design that generates extremely low-noise supply rails that are quite tolerant of badly designed computer power supplies. Another core technology pioneered for use in audio devices by Lynx is the use of field programmable gate arrays.

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.

Offer applies only to single-receipt qualifying purchases. No interest will be charged on the promo balance if you pay it off, in full, within the promo period. If you do not, interest will be charged on the promo balance from the purchase date. The required minimum monthly payments may or may not pay off the promo balance before the end of the promo period, depending on purchase amount, promo length and payment allocation. Regular account terms apply to non-promo purchases and, after promo period ends, to the promo balance. 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.
