The Quad Stereo Channel (QSC) consists of four stereo channels, with a design based on the Channel module that, however, also borrows some concepts from the Group and the Master modules. The color scheme reflects the same routing of the modules: VCA (red), two effect sends (yellow and green), pan (pink), auxiliary input (purple), and main faders (white).
This peculiar feature set allows you to use the QSC within a standard CGM configuration, or as a standalone stereo mixer with mono effect sends.
Four Voltage-Controlled Stereo VCAs with Saturation
Each channel features two amplitude controls: an input stereo VCA and a volume fader. The input VCA is voltage-controllable and, if the signal has enough amplitude, it can overdrive the circuit with a creamy, fat saturation. A peak LED tells when the signal is clipping, but don’t fear cranking it up!
Local Sum Output
Two unbalanced outputs (left and right) provide the local sum of the four channels. They allow you to use the QSC as a standalone, four-channel stereo mixer in smaller systems or parallel-process a QSC in larger setups.
Two Effect Sends per Channel (with CV)
The yellow and green knobs are two effect sends levels. They can work pre- or post-fader, and two of them can be voltage-controlled for expressive and creative results.
Pan/Crossfade Selection (CV?)
A switch lets you use the panpot for stereo placement or for crossfading between two monophonic sources. This last behavior can lead to using the QSC as a limited but effective eight-channel mono mixer! The first and fourth channels’ pan/crossfade sections can also be voltage-controlled.
Mute Buttons
The mute buttons allow you to remove a channel from the group sum with a click. The mute function works over the input VCA, so it will also mute the effect sends.
Solo-in-Place Switches
The Solo-In-Place button lets you prepare a “scene” of channels to be isolated from the other ones, and then recall it through the Safe Solo button on the Group module. It can be seen as a mute group function that allows you to mute all the channels outside the solo scene with a click.
PFL Switch
Push the PFL button and rotate the PFL fader on the master module to preview a channel: it’s convenient for tuning your oscillators or checking if everything is ok before bringing whatever sound source into the mix.
Mono Effect Send Outputs
Two monophonic jack outputs mirror the effect send sum sent to the group. In this way, you can take advantage of the QSC effect sends capabilities even in a compact system, where the group cannot fit. In larger setups, you can achieve some advanced effect routing by processing the same sum in two ways: one from the group and one from the QSC.
Auxiliary Mono Input
Should you run out of channels, the auxiliary mono input lets you add an additional monophonic signal to the final sum: no attenuation, no controls, just a straightforward input circuit!

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.
