IOU is a highly flexible DC-coupled signal processor, suitable for both CV and audio inputs. It features an attenuverter for precise signal scaling and inversion, alongside a unipolar DC offset slider with LED indicator. The DC offset slider provides up to +5V or +10V of precise offset control depending on the gain setting. A unique feature, resulting from a request by DivKid, is the ability to apply the offset either Pre or Post-attenuverter. When set to Pre-attenuverter, IOU allows for detailed, granular offsets across the entire slider range, offering fine-tuned control.
IOU includes a selectable output gain setting, allowing a choice between 1x and 2x. This feature is useful for amplifying low level input signals or doubling the DC offset control range up to +10V with the 2x setting.
The outputs are symmetrical, providing equal and opposite signals. This dual-output setup is useful for symmetrical voltage control, facilitating techniques such as sidechain compression (ducking) and crossfading when used in conjunction with VCAs.
IOU excels in CV signal scaling, inversion, and voltage offset, and is equally skilled at processing audio signals for attenuation, gain control, inversion, and clipping. Its features enable precise manipulation of signals for controlling other modules. This functionality enriches any Eurorack setup, facilitating more complex and creative patching possibilities.
IOU is an indispensable tool, crafted to enhance the functional range and versatility of your modular system.

Shipping methods
All EU orders are shipped via UPS. We offer two service levels:
- UPS Standard – our default shipping option. Delivery times vary by country (see estimated delivery times below).
- UPS Express Saver – next business day delivery to most EU destinations.
Each product page shows the estimated delivery time for your location, so you'll always know what to expect before you order.
Estimated delivery times (Standard shipping)

| Spain | 4 |
| Sweden | 3–5 |
These times are estimates and are not guaranteed. Delivery may occasionally take a little longer due to customs processing, local conditions, or carrier delays.
Dispatch times
Orders placed before 15:00 CET (Central European Time) on a working day are normally dispatched the same day. Orders placed after 15:00 CET, or on weekends and public holidays, will be dispatched on the next working day.
If you have an urgent order, please email us at info@signalsounds.eu before placing your order and we'll do our best to accommodate you.
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 at info@signalsounds.eu if you have questions.
