Get to know them!

With six inputs and four outputs, the ZonePRO 640 offers the state-of-the-art signal processing you need for a premium PA installation. To access its deepest functions, the entire system can be controlled by a computer via the GUI protocol, while the "Wizard" function offers streamlined and easy setup for any user - making the ZonePRO 640 great for use in houses of worship, and corporate installations, as well as in clubs, theaters, and other large performance spaces and conference halls. With per-channel EQ, as well as access to a host of DSP features on the mic/line inputs, the ZonePRO 640 delivers top-notch sound.

Can be controlled via computer

The ZonePRO 640 can be controlled by a computer, for easy and fast access to its deepest functions. Plus, it boasts a "Wizard" function so anyone - with any experience level - can comfortably optimize the unit to its complete potential.

Fully-featured for premium sound

The philosophy behind the ZonePro 640 is to "provide everything you need between the sources and the amplifiers," - and that's exactly what it does. Each input channel offers EQ, while the mic/line inputs also boast two DSP insert blocks where you can select Compression, Notch Filtering, Auto Gain Control, Advanced Feedback Suppression (AFSTM), Gating, and De-Essing for the ultimate sound. Plus, each output zone provides a routing matrix where you can choose each of the inputs as the main source or primary source. Paging can also be done from the mic/line inputs, where you have full ducking capability with both paging and priority override. On the outputs, you have Autowarmth, full Bandpass and Crossover filtering, as well as a Parametric EQ, selectable Dynamics module, and output Delay.

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.
