Expandable 4-Channel Audio and CV Utility

MIX, ATTENUATE, INVERT

Features:

  • Clean and precise manipulation, routing and mixing of CV and Audio signals.
  • Switchable mixer configurations: two 2-to-1 mixes, or one 2-to-1 plus a 4-to-1.
  • Expandable with other 221.x2 modules.
  • Direct Outs are switchable between Pre and Post attenuation/inversion.
  • Channels 2 and 4 are normalled with a 6V offset.
  • ∞ to +6 dB (aka 2x) gain on Summing knobs
  • LEDs for bipolar peak detection, and display of CV shape.

"A very versatile audio and CV mixer, attenuator and inverter. I always liked the Blood Cells Audio D.O.MIXX mixer and if that’s anything to go by the 221.x2 should be excellent." - Robin Vincent, Gearnews.com

"An impressively capable take on mixing and attenuversion. Versatile." - Greg Scarth, Juno

221.x2 is a clean and precise utility module that is equally at home mixing Control Voltage as it is audio. At its simplest, it is two independent 2-to-1 mixers that offer per-channel attenuation and inversion, as well as +6dB of gain available at the summed outputs. With a tap of the “All Mix” button, these separate mixes can be combined into a 4-to-1 mix at the “All Mix” output - meanwhile, the first 1+2 mix is still available at its respective summed output. A rear expansion input and output allows for combining multiple modules into larger systems.

In addition, each channel also offers a Direct Output that can be taken pre or post attenuation/inversion.

A 6-volt offset is normalled into the input jacks of channels 2 and 4. This voltage is available at the channel’s Direct Output, as well as added to the mixed outputs. Useful as an offset for mixing with another CV signal, or simply as a voltage source.

Each summed output group has two blue LEDs for displaying the shape of the summed CV, and can also serve as signal present indicators for audio. Peak LEDs trigger at ~9.6V, allowing for a bit of headroom before things get out of hand.

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.
