VCA with logarithmic and linear control inputs. It has a new front panel design with elongated holes.
Amplifiers have a simple job - they amplify or attenuate the signals presented to them. Voltage controlled amplifiers (VCAs) are more sophisticated... they allow you to control the amount of amplification or attenuation by applying a voltage to a CV input. VCAs exist in every synthesizer that can shape a sound.
You may think that it's the envelope that is, for example, changing the volume, but it isn't. The envelope is producing a CV that, when applied to the VCA, causes it to modify the signal passing through it. The VCA is one of the fundamental modules that allow us to make sounds develop over time.
VCAs need not be restricted to amplifying audio signals. Other configurations inclu de modulating a VCA using a Low Frequency Oscillator to produce the effect known as tremolo.
In sophisticated instruments, the speed and depth of the LFO can themselves be controlled by a VCA, so that the rate and intensity of the tremolo changes in time too.

CV Inputs
The RS-180N offers dual CV inputs. CV1-IN LIN responds linearly to incoming CVs, while the CV2-IN LOG input responds logarithmically. Traditional wisdom suggests that linear CV inputs are most useful for LFOs, whereas you should use the logarithmic response for envelopes. There is some basis for this, but you must remember that any signals can be presented to the CV inputs . Furthermore, you can use both CV inputs simultaneously, thus creating complex VCA responses.
Initial Level
The INITIAL LEVEL does what it says: with no CV s applied to either CV input, it determines the gain of the VCA. With the INITIAL LEVEL set to MAX and with no negative CVs applied to the CV inputs, the RS-180N will pass signals with no changes in amplitude. At the other extreme, with the INITIAL LEVEL set to MIN and with no positive CVs applied to the CV inputs, the RS-180N will pass no signals whatsoever.
If CVs fluctuating around 0V are presented to the CV inputs, the VCA gain will be modulated around the INITIAL LEVEL.
Inputs and Outputs
The VCA has two signal inputs: SIG 1 IN and SIG 2 IN, each with an associated LEVEL control. (The RS-180N incorporates a mixer so that the signals presented to these can be treated simultaneously.) The inputs accept both audio signals and CVs in the range ±10v. The LEVEL controls offer unity gain in the fully clockwise position, and completely attenuate the signal at their anticlockwise extreme.
There is a single output that carries a signal in the range ±10v.

How much is my shipping?
Shipping is automatically calculated before you submit your payment information. Simply add items to your cart and proceed to the checkout page, where you'll be offered shipping options and their prices. In the UK it's normally around £4 for order values under £150, and free above that. Shipping to mainland EU is typically between £7 and £20, depending on the shipping method and the size and weight of the order.
Do you ship to my country?
Almost certainly - the site will give you an estimate of shipping costs if you add an item to the cart and then enter your country and postcode. If you have specific requirements (such as if you prefer UPS over FedEx, for example) then let us know in advance and we'll try to work something out for you.
Shipping methods
We use a combination of Parcelforce, DPD, Royal Mail and UPS for the UK, and for international orders it's either Royal Mail, UPS, DHL or FedEx depending on where you are in the world. If you have a particular preference then try to let us know BEFORE you order so we can look into it for you. Please note that there may occasionally be additional shipping charges if you live in a remote area, depending on what surcharges are applied by the shipper. We'll get in touch to discuss this with you in such cases.
Dispatch times
For UK orders, we normally dispatch the same working day if we get the order before 15:00. If you have a really urgent situation then of course drop us an email before ordering and we'll always do our absolute best to accommodate you.
For international orders, we normally dispatch the same day if we get the order before 13:00 but again, occasionally it might be the next day before we can send it out, and sometimes FedEx or UPS may come a little earlier than scheduled which would also push an order into the next day.
Shipping times
Since April 2020 the couriers we use have suspended guarantees for shipping times, so even though we're paying them for priority services - 24-48 hours for most of the world - in practice it's often an extra day on top and sometimes it can be longer.
There is absolutely nothing we can do about this unfortunately. If you are outside the UK and it's a life-or-death situation where you absolutely MUST have that passive mult for the next day then... it may be better to find a local supplier.
Saturday shipping
If you're in the UK and you order before 15:30 on a Friday then we can send something for a Saturday delivery (NB: this applies to UK mainland addresses only). The success rate with DPD is about 95% so it's worth a punt most of the time. Please note that if you select Saturday shipping on an order placed earlier in the week, we'll wait until Friday to ship it.
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 if you have questions.
