Two Notes Torpedo C.A.B. M+ Speaker Simulator Pedal User Manual

1. Introduction

The Two Notes Torpedo C.A.B. M+ is a versatile speaker simulator pedal designed for guitarists and bassists. It provides high-quality cabinet simulation, microphone placement options, and power amp simulation, allowing musicians to achieve studio-grade tones without traditional speaker cabinets. This device is ideal for silent practice, direct recording, and live performance setups where a physical cabinet is not practical or desired. The C.A.B. M+ also features a clean preamp and reverb capabilities, expanding its utility as a complete tone solution.

2. Setup

Proper setup ensures optimal performance and sound quality from your Torpedo C.A.B. M+.

2.1. Power Connection

Connect the included 12VDC/200mA power supply to the 'POWER' input on the rear of the unit. Ensure the power supply matches the specified voltage and current requirements.

2.2. Audio Connections

The Torpedo C.A.B. M+ offers various input and output options for different setups:

• GTR / AMP IN: This input accepts signals from your guitar, pedalboard, or the speaker output of an amplifier. If connecting from an amplifier's speaker output, ensure a speaker cabinet is always connected to the amplifier's speaker output to prevent damage to the amplifier.
• SPEAKER OUT: If using the 'GTR / AMP IN' from an amplifier's speaker output, connect your speaker cabinet to this output. This acts as a pass-through for your amplifier's signal to the cabinet while the C.A.B. M+ processes a parallel signal.
• IN LEVEL Switch: Adjust this switch (-24dB AMP, 0dB, +12dB GTR) to match the input signal level. Use -24dB AMP for amplifier speaker outputs, 0dB for line-level signals, and +12dB GTR for direct guitar/bass signals.
• LINE OUT: A 1/4-inch unbalanced output for connecting to an audio interface, mixer, or other line-level devices.
• DI OUT: A balanced XLR output for direct connection to a mixer or audio interface, providing a clean, low-noise signal. Use the 'GND LIFT' switch to eliminate ground hum if present.
• AUX IN: A 1/8-inch (3.5mm) stereo input for connecting external audio sources like a smartphone or music player for practice.
• Headphone Output: A 1/8-inch (3.5mm) stereo output for silent practice with headphones.

4. Maintenance

To ensure the longevity and optimal performance of your Torpedo C.A.B. M+:

• Cleaning: Use a soft, dry cloth to clean the exterior. Avoid abrasive cleaners or solvents.
• Firmware Updates: Regularly check the Two Notes Audio Engineering website for firmware updates. Updates often include new features, improvements, and bug fixes. Connect the unit to your computer via USB and use the Torpedo Wall of Sound software to perform updates.
• Storage: Store the unit in a cool, dry place away from direct sunlight and extreme temperatures.

5. Troubleshooting

If you encounter issues with your Torpedo C.A.B. M+, refer to the following common solutions:

• No Sound Output:
  • Check all cable connections (input, output, power).
  • Ensure the 'IN LEVEL' switch is set correctly for your input source.
  • Verify that the volume knob on the unit is turned up.
  • If using an amplifier's speaker output, confirm a physical speaker cabinet is connected to the amplifier's speaker output.
• Excessive Noise/Hum:
  • Use the 'GND LIFT' switch on the DI OUT to eliminate ground loops.
  • Ensure proper gain staging throughout your signal chain. High input levels or excessive gain settings on the C.A.B. M+ or subsequent devices can introduce noise.
  • Test with a different power supply if possible, ensuring it meets specifications.
• Unit Not Responding:
  • Disconnect and reconnect the power supply.
  • If connected to a computer, try restarting the Torpedo Wall of Sound software and reconnecting the USB cable.
• Preset Switching Delay:

  It is normal for there to be a noticeable delay when switching between presets. This is due to the processing required to load new cabinet and effect models. Plan your live use accordingly, typically by selecting a single preferred preset for a song or section.
