Next-gen 500 Series Classic EQ

Get to know them!

The WesAudio Prometheus is a 500 Series stereo/dual-mono/mid–side 2-band passive analog EQ with +24dBu of headroom. Prometheus delivers warm, classic Pultec-style sonics along with digital recall that gives you complete control via its companion plug-in. Connectivity to your computer is handled via a front-panel USB port — or by a special rear-panel connector — that allows it to communicate with its free companion plug-in for complete control and automation within your DAW. A member of the company's ng500 product line, Prometheus features a special connector (an extension of the standard connector found on all 500 Series modules), that allows it to mate with WesAudio's _TITAN ng500 Recall Chassis. It also works in most standard 500 Series racks. Aside from its total recall capabilities, Prometheus offers extensive flexibility for sculpting your sound.

Classic passive sound-shaping mojo

Prometheus offers two bands of classic passive equalization with a Pultec-style twist that lets you both boost and cut in an overlapping range of upper-mid and high frequencies. The faceplate is fitted with six touch-sensitive encoders allowing for automation of each parameter within your DAW. Prometheus features proprietary analog circuit control that eliminates glitches and artifacts due to encoder movement, allowing for full automation without unwelcome side effects. LF Boost/Cut is selectable between 20, 30, 60, 100, 120, and 250Hz. HF Boost is selectable between 2, 3, 4, 5, 8, 10, 12, and 16kHz and offers a variable Bandwidth encoder. HF Cut is selectable between 4, 8, 12, and 20kHz. A post-EQ Output encoder is provided. The Boost and Cut controls are also rotary encoders.

If the feature set ended there, Prometheus would still be a formidable studio tool. But the innovations continue with a THD control, switchable between Medium and High settings, that warms up your signal with tasty vintage-flavored even-order harmonics, A/B presets for easy wet/dry signal comparisons, and more. And here's where Prometheus really breaks away from the pack, offering full control and automation via its free companion plug-in, with connection to your computer handled by a front-panel USB jack, or via WesAudio's _TITAN ng500 Recall Chassis.

Prometheus Companion Plug-in

Total recall with ng500

WesAudio, a company masterminded by Radoslaw Wesolowski and headquartered in Poland, is spearheading an initiative they call ng500. The "ng" stands for next-generation. The company's ng500 product line starts with 500 Series modules that have a special connector, an extension of the standard connector found on all 500 Series modules. The extra pins on the extended connector mate with receiver connectors in WesAudio's _TITAN ng500 Recall Chassis. On its rear panel, the _TITAN is fitted with a USB jack for connection to your computer, as well as Ethernet for networked setups. All ng500-compatible modules in the rack will be able to communicate with your computer via a single data cable. Each module includes free downloadable software that appears in your DAW session as a standard plug-in and lets you control your analog hardware with software precision. Every setting and automation move is saved along with your DAW session file.

Works in most standard 500 Series racks

You don't need a _TITAN to use Prometheus; ng500 modules are fully functional in most standard 500 Series racks (contact your Sweetwater Sales Engineer for specifics). Each module features a front-panel USB connection you can connect to your computer for use with its respective companion plug-in for total control over one module at a time. But with the _TITAN ng500 Recall Chassis, you have complete control over all mounted modules.

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.

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.
