Setup

Follow these steps to set up your Acoustic Singer Live amplifier:

1. Power Connection: Connect the supplied AC power cord to the AC IN jack on the rear panel of the amplifier and then to a suitable power outlet. Ensure the power switch is in the OFF position before connecting.
2. Instrument Connection: Connect your acoustic guitar to the GUITAR input jack using a standard 1/4-inch instrument cable.
3. Microphone Connection: Connect your microphone to the MIC input jack using an XLR cable. If your microphone requires phantom power, ensure the PHANTOM switch is set to ON.
4. Auxiliary Devices: For connecting external audio players, use the AUX INPUT jack.
5. Foot Control: Optional footswitches (e.g., BOSS FS-5L, FS-6, FS-7) can be connected to the FOOT CONTROL jacks for hands-free operation of features like looper, chorus, and harmony.
6. Power On: Once all connections are secure, turn on the power switch located on the top right of the control panel.

Operating Instructions

The Acoustic Singer Live features two independent channels for guitar and vocals, each with dedicated controls and effects.

Guitar Channel Controls

• PAD: Reduces the input level for high-output pickups.
• ACOUSTIC RESONANCE: BOSS's proprietary technology that restores the natural, resonant tone of your acoustic guitar, often lost with piezo pickups.
• VOLUME: Adjusts the overall volume of the guitar channel.
• BASS, MIDDLE, TREBLE: 3-band EQ for precise tone shaping.
• ANTI-FEEDBACK (NOTCH/PHASE): Helps eliminate feedback. The NOTCH control targets specific frequencies, while PHASE inverts the phase of the input signal.
• CHORUS (TYPE1/TYPE2): Adds depth and richness to your guitar sound. Select between two distinct chorus types.
• REVERB: Adds spaciousness and ambience to the guitar signal.

Mic Channel Controls

• PAD: Reduces the input level for high-output microphones.
• PHANTOM: Provides +48V phantom power for condenser microphones.
• VOLUME: Adjusts the overall volume of the microphone channel.
• BASS, MIDDLE, TREBLE: 3-band EQ for vocal tone shaping.
• ANTI-FEEDBACK (NOTCH/PHASE): Similar to the guitar channel, helps control vocal feedback.
• DELAY/ECHO: Adds a repeating echo effect to your vocals.
• REVERB: Adds spaciousness and ambience to the vocal signal.

Harmony Function

The Harmony function automatically creates smooth and accurate vocal harmonies based on the real-time key/chord analysis of your guitar input. This feature is particularly useful for solo performers.

• ON/OFF: Activates or deactivates the harmony effect.
• TYPE: Selects the harmony type (e.g., HIGH, UNISON, LOW) to add different vocal layers.
• LEVEL: Adjusts the volume of the generated harmony voices.

Looper

The built-in looper allows you to record and layer guitar and vocal phrases, creating full backing tracks on the fly.

• REC/PLAY/OVERDUB: Controls the recording, playback, and overdubbing of loops.
• STOP/CLEAR: Stops playback and clears the current loop.

Master Controls

• MASTER: Controls the overall output volume of the amplifier.
• TWEETER ATT: Attenuates the tweeter output, useful for adjusting the high-frequency response.
• MUTE: Mutes the entire output of the amplifier.
