A-105-4 is our first polyphonic filter and contains four identical 24dB Lowpass filters (SSM2044/SSI2144 type). It has available common manual controls and CV inputs with attenuators for all parameters.
The module has these controls and in/outputs are available:
Frequency F: manual control (common for all filters)
Frequency Modulation Intensity FM: manual control (common for all filters)
Resonance Q: manual control (common for all filters)
Audio Input Level L: manual control (common for all filters)
CVF control: attenuator for Frequency Control Voltage CVF (common for all filters)
CVFM control: attenuator for Frequency Modulation Control Voltage VCFM (common for all filters)
CVQ control: attenuator for Resonance Control Voltage CVQ (common for all filters)
CVL control: attenuator for Level Control Voltage CVL (common for all filters)
CVF socket: Frequency Control Voltage CVF (common for all filters)
CVFM socket: Frequency Modulation Control Voltage VCFM (common for all filters)
CVQ socket: Resonance Control Voltage CVQ (common for all filters)
CVL socket: audio input Level Control Voltage CVL (common for all filters)
FM Input 1 - 4: CV input for frequency modulation (separate for each filter)
Audio Input 1 - 4 (separate for each filter)
Audio Output 1 - 4 (separate for each filter)
Each filter has available a separate FM input as well as an Audio Input and Audio Output. The FM inputs are typically connected to the outputs of the associated envelope generator (e.g. A-141-4). The envelope amount for all four filters is controlled by the FM knob and the CVFM input by means of four built-in VCAs, which are controlled by the FM control and CVFM input. This allows also voltage control of the envelope amounts.
In addition common frequency modulation for all filters is possible (e.g. by an LFO). For this the CVF input with attenuator can be used.
The range of the audio input level control (L) allows also clipping/distortion with typical A-100 audio levels (e.g. from A-111-4) at the filter inputs. Even this parameter is voltage controllable as well as the resonance (Q).
Application: polyphonic patches (four VCFs with same parameters) or other structures where 2 or more simultaneously controllable filters are requried (e.g. stereophonic oder quadrophonic applications)
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.
