QuadroPol is composed of four voltage controllable attenuators, which can also be employed as inverters, ring modulators, VCAs or CV sources. Several channels can be combined to form a mixer. Thanks to the potentiometers’ “dead zone”, setting the attenuators to their zero-point is easy as pie. QuadroPol can process audio signals as well as control voltages. Built-quality and sound are excellent.
QuadroPol comes equipped with four identical attenuators. Each of the circuits features an input, a potentiometer and a CV connector for adjusting the level as well as an output. With the knobs set to 12 o’clock position, incoming signals don’t get passed through the attenuators. The zero-point is very wide and therefore easily reachable. By turning the potentiometers to the right, users can increasingly open the circuits. Turning the control elements to the left has basically the same effect, but with inverted phase. Thanks to the CV inputs, which have an operational range of -5 V to +5 V, the attenuators can also be controlled via other modules. This feature allows users to employ the circuits as VCAs. The dynamic range is 80 dB. With audio material being fed to both the input and the CV connector of an attenuator, it works as a ring modulator. As long as no cables are plugged into the inputs, they get normalized to a fixed voltage. Using the level potentiometers, it is possible to shift the resulting CV signals in the range of -5 V to +5 V. The attenuators’ outputs can be interconnected via jumpers. As a result, it is possible to use the Quadropol as a mixer with two to four channels.

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.
