Because we are a major distributor for some products, we price very aggressively by sacrificing profit margin whenever we sell in bulk. The philosophy to offer quality products with little mark up has created unmatched customer loyalty for some successful membership based stores. Unlike those wholesale to public membership clubs, we do not charge any membership fee. Some merchants offer FREE shipping, but when you buy quantity 10, you pay 10 times total. Essentially, you are paying 10 times on shipping. We don't think that is fair to you. Why? Most of the time, shipping a 10 lb parcel does not cost 10 times of a 1 lb parcel.

Here is an example:

Opentip	Others
Product Price: $8.00	Product Price: $20.00

Total Shipping for quantity 10: $18.00	Total Shipping: FREE
Subtotal: $98.00 Saving: $102.00 (51%)	Subtotal: $200.00

Don't be shy. If you discover any competitor outselling us in a particular product, whenever you purchase in large quantity, please bring it to our attention. Most of the time, we will match or beat their price, and give you a credit. If we lose to a competitor, it is our shame. We then know we need to work harder in sourcing to create values for you.

* Price comparison must be based on comparable brands or models and in bulk quantity purchase.

* Price: $8.40 ea X 1 qty = $8.40

Product Description

Manufacturer Part Number: P-Q-SSI2140

A refresh of a classic design, the FatKeys™ SSI2140 preverses mojo of the beloved SSM2040 and adds temperature compensation of gm cells and the exponential control port. A "Q VCA" is provided to allow easy resonance control as well as various options for Q compensation. The four transconductance cells are highly configurable for a variety of pole and mode combinations.

The SSI2140 is a new-generation voltage controlled filter that provides four highly-configurable variable transconductance cells for a wide variety of pole and mode combinations, and adds significant new features.

Based on an updated core by original SSM2040 designer Dave Rossum, the SSI2140 temperature compensates its transconductance cells for unprecedented stability. Temperature compensation is also optionally available for the exponential control.

A temperature compensated VCA with linear control allows easy control of resonance and supports multiple Q compensation schemes, or otherwise can be used for traditional VCA/VCF roles.

Virtually any type of filter response from one to four poles can be achieved including low-pass, high-pass, band-pass, all-pass, notch, Sallen & Key, biquad, Cauer, state-variable, and others.

Most importantly, great care was taken to preserve the SSM2040's sonics including an input stage that can be overdriven for classic analog synthesizer character.
