1. Introduzione
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. Connection Power
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 esigenze attuali.
2.2. Cunnessioni Audio
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 amppiù vivu.
- ORATORE: 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 per 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.
- Output per cuffie: A 1/8-inch (3.5mm) stereo output for silent practice with headphones.
