10 Fully Isolated Outputs
Unlike basic daisy-chain power supplies, the Caline CP-04 uses individually isolated outputs to deliver clean, stable power to each pedal. Isolation helps reduce ground loops, hum and unwanted electrical interference, keeping your signal clean even when running multiple pedals.
Multiple Voltage Options
The CP-04 provides a combination of outputs to power a wide range of effects pedals.
- 4 × 9V DC 100mA outputs
- 3 × 9V DC 300mA outputs
- 1 × 9V DC 500mA output
- 1 × 12V DC 300mA output
- 1 × 18V DC 100mA output
This combination allows you to power everything from low-current analog pedals to higher-current digital effects and pedals requiring 12V or 18V operation.
Independent Protection on Every Output
Each power output includes its own short-circuit and overcurrent protection. If one connected pedal develops a fault, the remaining outputs continue operating normally, helping protect both your pedals and power supply.
Ultra-Low Noise Performance
Clean power is essential for preserving your guitar tone. The isolated circuitry minimizes power-related hum and interference, making the CP-04 ideal for high-gain rigs, studio recording and professional live performances.
USB Charging Port
A convenient USB output allows you to charge smartphones, wireless systems or other USB-powered accessories while you’re rehearsing or performing.
Built for the Road
Constructed from durable aluminum alloy, the CP-04 is designed to withstand regular transport and gigging while remaining lightweight enough for compact pedalboards.
Simple LED Status Indicators
Integrated LED indicators make it easy to check power status at a glance. The front LED switch also allows you to turn the indicator lights on or off depending on your preference.
