Blackstar Dept 10 Dual Distortion Pedal User Manual

1. Introduction

The Blackstar Dept 10 Dual Distortion pedal is a high-gain valve distortion unit and a recording preamp designed for guitarists. It features a genuine ECC83 valve, offering three crunch/overdrive voices in addition to a clean channel. Key functionalities include Blackstar's patented ISF (Infinite Shape Feature) control, low-latency USB audio connectivity, an XLR output, and the proprietary Cab Rig simulator technology.

The integrated Cab Rig simulator provides detailed reproductions of miked guitar cabinets, accessible via USB/XLR output or headphones. An effects loop is included for seamless integration with other pedals, and the XLR D.I. output allows for direct connection to a mixing console, functioning as a backup amplifier solution.

2. Setup

Follow these steps to set up your Dept 10 Dual Distortion pedal:

1. Power Connection: Connect a 9V DC, 500mA power supply (center negative) to the "9V DC 500mA" input jack on the rear of the pedal. Ensure the power supply meets these specifications to prevent damage.
2. Instrument Input: Connect your guitar or other instrument to the "INPUT" jack on the right side of the pedal using a standard 1/4-inch instrument cable.
3. Output Connection:
   • For connection to a guitar amplifier, use the "OUTPUT" jack on the left side of the pedal.
   • For direct recording or PA system connection, use the "LINE OUT" XLR jack on the rear.
   • For headphone monitoring, connect headphones to the "CAB RIG" 1/4-inch jack on the left side.
4. Effects Loop (Optional): If using external effects pedals, connect them via the "SEND" and "RETURN" 1/4-inch jacks on the rear. The "SEND" jack connects to the input of your external effect, and the output of your external effect connects to the "RETURN" jack.
5. USB Audio (Optional): For recording or using the Cab Rig software, connect a USB cable from the "USB AUDIO" port on the rear to your computer.

3. Operating Instructions

The Dept 10 Dual Distortion pedal features two independent channels, each with distinct gain and level controls, and a shared EQ section.

3.1. Controls Overview

• CH 1 Footswitch: Activates or deactivates Channel 1. The associated LED indicates its status.
• CH 2 Footswitch: Activates or deactivates Channel 2. The associated LED indicates its status.
• Gain 1: Adjusts the amount of distortion for Channel 1. The "CL" (Clean) and "CR" (Crunch) switch selects the voice for Channel 1.
• Level 1: Controls the output volume for Channel 1.
• Gain 2: Adjusts the amount of distortion for Channel 2. The "OD 1" (Overdrive 1) and "OD 2" (Overdrive 2) switch selects the voice for Channel 2.
• Level 2: Controls the output volume for Channel 2.
• Bass: Adjusts the low-frequency response of both channels.
• Middle: Adjusts the mid-frequency response of both channels.
• Treble: Adjusts the high-frequency response of both channels.
• ISF (Infinite Shape Feature): This patented control allows for continuous adjustment between a British-style amplifier response (counter-clockwise) and an American-style amplifier response (clockwise).
• Cab Rig: This control selects between different Cab Rig simulator presets when using the CAB RIG output (XLR or 1/4-inch headphone jack). Presets can be customized using the free Blackstar Architect software via USB.

3.2. Using the Cab Rig Simulator

The Dept 10 Dual Distortion features Blackstar's Cab Rig DSP speaker simulator. This technology allows you to reproduce the sound and feel of a miked guitar cabinet directly through headphones, a PA system, or a recording interface.

• Connect headphones to the "CAB RIG" 1/4-inch output for silent practice.
• Connect the "LINE OUT" XLR to a mixing console or audio interface for direct recording or live sound.
• Use the "Cab Rig" knob on the pedal to cycle through onboard presets.
• For advanced customization, download the free Blackstar Architect software. Connect the pedal to your computer via the "USB AUDIO" port. The software allows deep-editing of virtual cabinets, microphones, and room environments.

3.3. Effects Loop

The built-in series effects loop allows for the integration of external effects pedals into your signal chain. This is particularly useful for time-based effects (like delay or reverb) that often sound best after distortion.

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

4. Maintenance

To ensure the longevity and optimal performance of your Dept 10 Dual Distortion pedal, observe the following maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the pedal's exterior. Avoid abrasive cleaners, solvents, or excessive moisture.
• Storage: Store the pedal in a cool, dry environment away from direct sunlight, extreme temperatures, and humidity.
• Valve Care: The ECC83 valve is a delicate component. Avoid dropping the pedal or subjecting it to strong vibrations. If the valve needs replacement, consult a qualified technician or Blackstar support.
• Power Supply: Always use a compatible 9V DC, 500mA (center negative) power supply. Incorrect power can damage the unit.

5. Troubleshooting

If you encounter issues with your Dept 10 Dual Distortion pedal, refer to the following common troubleshooting steps:

• No Sound:
  • Ensure the power supply is correctly connected and functioning.
  • Verify all instrument cables are securely connected to the input and output jacks.
  • Check that the volume controls (Level 1, Level 2, and your amplifier/interface) are not set to zero.
  • Confirm that the active channel footswitch LED is illuminated.
• Excessive Noise/Hum:
  • Ensure you are using a high-quality, isolated power supply. Ground loops can introduce hum.
  • Test with different cables to rule out faulty instrument cables.
  • Move the pedal away from other electronic devices that may cause interference.
  • If using high gain settings, some noise is inherent. Consider using a noise gate pedal in your signal chain.
  • A faulty valve can sometimes introduce noise. If suspected, consult a technician.
• USB Audio Not Recognized:
  • Ensure the USB cable is securely connected to both the pedal and your computer.
  • Try a different USB port on your computer.
  • Install the latest drivers for the Dept 10 series from the Blackstar website.
  • Restart your computer and the pedal.
