Manufacturer's description
Moog type ladder filter VCF (LPF). New completely designed mk 3 ladder filter. Superb sounding low pass filter giving that authentic vintage Moog type sound.
Filters are the means by which we modify sounds to create new sounds. The most common way in which they do this is by removing parts of the audio spectrum - attenuating the low frequencies and/or the high frequencies, or maybe by creating 'holes' in the spectrum. Other types of filter may enhance parts of the spectrum, or they may act in the time domain, removing sections of the signal rather than modifying its frequency response.
The most common filter in analogue synthesis is called the low-pass filter and its name exactly describes its function: it passes the part of the spectrum below its cut-off frequency, but attenuates those frequencies that lie above the cut-off frequency.
The most highly revered low-pass filter in analogue synthesis was developed by Dr Robert Moog in the late 1960s. It first appeared in the modular Moog synthesizers of that decade, but its finest hour came in 1970 with the appearance of the Minimoog. Largely because of its filter, this rather limited instrument has remained the standard by which all others are measured, and has survived nearly 40 years with its reputation intact as the most desirable of all integrated monophonic synthesisers.
Moog's filter used a circuit called a ladder network. In itself, there is nothing special about this, and many other filter designs are capable of emulating its response. However, Moog's circuit was flawed because it exhibited a small amount of distortion. Many engineers would have sought to correct this but those at Moog Music did not, perhaps because they recognised that the sound was musically pleasing. Indeed, if a synthesiser sounds like a Minimoog, it is called "warm" or "creamy". If it does not it will often be referred to as "thin" or "uninspiring".
The RS-100S 24dB/oct low-pass filter imitates the Minimoog's filter and exhibits almost identical characteristics in both the frequency domain (i.e. what it does to audio signals) and the time domain (i.e. its response over time to CVs). Below the cut-off frequency the response is approximately flat down to DC. With the filter fully open, it will pass signals approaching 20kHz.

These times are estimates and are not guaranteed. Delivery may occasionally take a little longer due to customs processing, local conditions, or carrier delays.
Dispatch times
Orders placed before 15:00 CET (Central European Time) on a working day are normally dispatched the same day. Orders placed after 15:00 CET, or on weekends and public holidays, will be dispatched on the next working day.
If you have an urgent order, please email us at info@signalsounds.eu before placing your order and we'll do our best to accommodate you.
Pre-orders
If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.
If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch at info@signalsounds.eu if you have questions.
