the spectral processor is a set of 16 bandpass filters with several special functions and dedicated outputs. a few new features separate the sputnik spectral processor from the 296r buchla format version.
bandpass program control now features discrete transistor vcas on all channels.
odd and even amp control can now be fully attenuated and additional soft saturation can be applied beyond 60% of travel for the odd/even amp level controls.
bandpass faders now control both eq and program output levels, rather than just eq on the 296r version.
consolidated design on a low profile, single pcb with integrated soft start and reverse power protection as well as significantly reduced current consumption.
programmed outputs
the heart of the spectral processor is the programmable control of the 16 filters. the program control section features frequency and width controls for selecting and sweeping through the active bandpass filters. local program inputs above each band provide direct control over the level of each filter. spectrum transfer activates the associated odd or even bandpass filter envelope followers to control the other, such as needed in the classic vocoder function. this can be applied to any two inputs in order to 'analyze' the spectral density of one of the inputs and impart this dynamic energy onto the other.
16 band equalizer
the 16 bandpass filters feature a dedicated attenuator and can provide up to +6db of additional gain per channel. input signals can be directed to the odd/even numbered filters exclusively or all 16 filters simultaneously via input jack normalization. dedicated odd and even sum outputs are provided as well as a full summed output for all 16 bands of the eq feature.
direct outputs
direct outputs are provided for each bandpass filter, as well an envelope follower; offering a dynamic control voltage of a specific band's energy content.
prefader outputs
summed outputs for the odd and even numbered direct outputs.

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.
