A Slew Limiter - also called a "Lag Processor" - is an example of a voltage processor. It produces no signal of its own, but affects those presented to its input.
Slew acts upon rapid changes in a signal, slowing them by an amount determined by manual and/or CV controls. Portamento is a perfect example of slew applied to a control signal: the slew circuit smooths the transitions between the stepped CVs normally used to determine pitch, thus making one note 'glide' to the next rather than jumping abruptly as it would otherwise do.
When applied to an audio signal, a slew limiter acts as a low-pass filter. On the RS-350 the maximum slew rate is about 100mS per volt, so a 1V signal can reach a frequency of just 5Hz before it is attenuated. (This is quite unlike the Slew Limiter in the RS-30 Frequency/Voltage Converter and Envelope Follower, which passes signals of up to 500Hz, or that in the RS-70 Pre-Amp, which allows signals of up to 5kHz to pass unimpeded.)
Unlike the other slew limiters in the RS Integrator, the RS-350 is voltage controlled, allowing you to control the amount of slew (or 'glide') dynamically. This permits a number of interesting possibilities that are not available elsewhere. For example, applying the keyboard CV to the V-IN socket, and an inverted/offset keyboard CV to the CV-IN allows you to decrease the glide time as you play up the keyboard, and increase it as you play down the keyboard. This is a very 'natural' sounding effect, rarely found on electronic synthesisers.
The RS-350 also offers an on/off CV that allows you to determine whether the original or the slewed signal is passed to the output. You can use this to jump between the target voltage and the intermediate, slewed voltage. This creates glissando type effects. You can, of course, use this together with the voltage controlled slew time to generate a wide range of unusual CV signals.
SLEW TIME:
This allows you to adjust the amount of slew applied to the input signal. At its minimum (fully anticlockwise) the slew time is about 100mS per volt. At its maximum (fully clockwise) the slew time is about 2S per volt.
V-IN:
The input accepts any signal in the range 0V - 10V.
CV-IN:
This accepts a CV in the range ±10V. The greater the CV presented, the greater the slew time becomes, thus slowing the transition from one voltage to another. (A negative voltage decreases the slew time.) You can apply a wide range of Gates and CVs to this input to create complex slew profiles.

Shipping methods
All EU orders are shipped via UPS. We offer two service levels:
- UPS Standard – our default shipping option. Delivery times vary by country (see estimated delivery times below).
- UPS Express Saver – next business day delivery to most EU destinations.
Each product page shows the estimated delivery time for your location, so you'll always know what to expect before you order.

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.
