4. Setup and Connections

4.1. Power Supply

The JOYO R-15 requires a DC 9V power supply (center minus, 400mA current). For optimal performance and to avoid unexpected noise, it is recommended to use an original JOYO power adapter or another reliable brand that meets the specifications.

4.2. Basic Connections

• Connect your guitar to the INPUT jack.
• Connect the OUTPUT jack to your amplifier's input or a power amp.
• For direct recording or PA systems, use the BALANCED OUT (XLR) jack.
• For silent practice, connect headphones to the HEADPHONE jack.

4.3. FX LOOP Connection

To integrate external effects pedals (e.g., time-based or modulation effects) into the signal chain after the preamp, use the SEND and RETURN jacks:

• Connect the SEND jack to the input of your external effects pedal.
• Connect the output of your external effects pedal to the RETURN jack.

5. Operating Instructions

5.1. Powering On/Off

Ensure all connections are made before powering on. The pedal powers on automatically when connected to a power supply. To turn off, disconnect the power supply.

5.2. Selecting Amp Models and Channels

• Use the 9-position rotary switch to select your desired amp model.
• Press the A footswitch for the Clean channel or the B footswitch for the Distortion channel.

5.3. Saving Settings

To save the current knob settings for an active channel (A or B) of a specific amp model, long-press the corresponding footswitch (A or B) until the ambience lights blink, indicating the settings have been saved.

5.4. Adjusting Tone

Use the GAIN, BASS, MID, TRE, VOL, and MASTER knobs to fine-tune your sound. Experiment with different settings to achieve your desired tone.

5.5. Using Cabinet Simulation

The CAB SIM toggle switch allows you to apply cabinet simulation to your outputs. This is particularly useful when connecting directly to a mixer or audio interface for a more polished, amp-like sound without needing a physical cabinet.

5.6. Ambience Lights

The pedal features ambience lights that can be configured via a small switch on the side:

• SYNC mode: Lights flicker in sync with the panel indicator when tone parameters change.
• ALWAYS mode: Lights are always on.
• OFF mode: Lights are off.
