Compact Power Expansion, Maximum Flexibility
The CIOKS 4 Expander is a compact, ultra-flexible power supply designed to add four fully isolated outputs to your pedalboard without taking up unnecessary space.
Originally designed as the perfect companion to the CIOKS DC7, the CIOKS 4 connects directly to the DC7’s 24V auxiliary output, instantly adding four additional isolated power outlets for growing pedalboards.
Each output offers selectable voltages of 9V, 12V, 15V, or 18V, with up to 660 mA available per output at 9V, making the CIOKS 4 suitable for everything from standard analog pedals to demanding modern digital effects.
More Than Just an Expansion Unit
What makes the CIOKS 4 particularly versatile is its ability to operate far beyond a traditional expansion supply.
Thanks to its flexible power input design, it can be powered from 9-24V DC, 9-12V AC, or even via 5V USB, allowing it to function as a compact standalone isolated power supply in a wide range of setups.
This makes the CIOKS 4 equally useful for expanding an existing CIOKS system, converting unused AC outputs from older supplies into isolated DC power, or creating an ultra-compact standalone solution for smaller boards.
Built for Modern Pedalboards
With its ultra-low profile design and included mounting hardware, the CIOKS 4 integrates easily with modern pedalboard systems from Pedaltrain and Temple Audio, while maintaining the ultra-low noise performance CIOKS is known for.
Small, powerful, and exceptionally adaptable, the CIOKS 4 is one of the most flexible compact power solutions available.
