The Acus One For Street 5 Wood is a 40 W acoustic guitar amplifier for buskers, singer-songwriters and others who need a compact solution for guitar, vocals and backing tracks. It can run on a separate 18 V battery or the included external power supply.

• 40 W acoustic combo
• 18 V battery operation; battery not included
• Microphone and instrument inputs can be used simultaneously
• 3-band EQ, reverb and separate master volume
• Balanced Direct Out with -10 dB attenuation
• AUX input and included Acus Artesia BT-1 Bluetooth adapter

Simultaneous instrument and vocal connection

The amplifier features both a microphone input and an instrument input, which can be used at the same time. Phantom power is permanently active on the microphone input, allowing it to be used with both dynamic and condenser microphones. The instrument input can be used for acoustic guitar, violin, mandolin or ukulele, for example.

Both channels have gain/volume, 3-band EQ for bass, midrange and treble, and a level control for the built-in reverb. This allows you to adjust the balance between instrument and vocals and add ambience without external effects.

Backing tracks and external audio connection

The AUX section includes a 3.5 mm jack input and mini-USB for the Acus Artesia BT-1. The included Bluetooth adapter allows music or backing tracks to be streamed from a smartphone. The AUX level is adjusted separately, so the balance between playback and your own performance can be set independently.

The balanced Direct Out sends the signal to an external sound system. The output features -10 dB attenuation, allowing the signal level to be reduced when needed.

Battery operation for mobile performances

The amplifier can run on an 18 V battery installed in the battery compartment. The battery is not included, and Acus recommends Makita 18 V batteries rated at 3 or 5 Ah. An LED indicates the battery status. The included power supply does not charge the battery.

The 2-way speaker system consists of a 30 W woofer and a 10 W tweeter. The frequency response ranges from 50 Hz to 20 kHz. The amplifier weighs 7 kg and measures 253 x 305 x 280 mm.
