The GATE BOOST amplifies +5V gate, trigger and clock pulses so that they can be used with older synth equipment that requires higher voltage signals. While it was designed to complement my CV.OCD MIDI to CV box, it can be used to amplify 5V gate signals from other equipment too.
The module can be powered using a supply of 7-15V DC with a 2.1mm centre negative plug and a 100mA or higher rating, such as a 9V effect-pedal type supply. Dual parallel power sockets allow you to power both the GATE BOOST and CV.OCD from the same power supply using a male-to-male power cable (supplied). Power supply is not included.
Use standard 3.5mm mono patch cables to connect the four inputs to your CV.OCD (or other equipment) gate outputs, and the corresponding four output sockets to your synth inputs.
The output voltage for each pair of channels (1/2 and 3/4) can be selected to use an internally generated +10V reference, or the power supply voltage, if higher (e.g. 12V, 15V). Two DIP switches on the front of the unit select the output pulse voltage for each pair of channels.
Four BLUE LEDs show the input signal status on each channel and work whether the device powered or not. This enables the GATE BOOST to be used as a tool for simple checks on gate and CV signals.
Each channel’s input signal passes through a circuit that applies a voltage threshold and “hysteresis” to determine when the output should be ON or OFF. This ensures crisp rising and falling rising edges on the output even when the input is a non-square wave form or is noisy.
This device is only needed for synths that need more than +5V to trigger them. It works only for “V-Trig” inputs not “S-Trig” (shorting) inputs. Please make sure you check the requirements of your synth before ordering.
Module is approx 9 x 4 x 2.5 cm Hand-made in Brighton, UK
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.
