Blackstar U250 overview

  • 1Description

The Blackstar U250 is a Unity Series 15" 250W bass amplifier designed to deliver versatile tones, built-in effects, and stage-worthy power for bassists recording in the studio and performing in concerts. It features 250W of solid-state power driving a custom-designed Eminence Opus 15" speaker mounted in a closed-back cabinet. Available via dedicated top-panel controls are three amp voices, three overdrive types, and three power amp response types. Built-in adjustable effects include chorus, octaver, and compression. A footswitch is provided for hands-free toggling of the chorus and octaver.

Effectively manage your gain structure using the input gain, clip indicator, -10 dB pad, master volume. The pad allows easy accommodation of basses with low-output passive pickups or hot active electronics. Shape your tone with the 3-band EQ, which boasts a semi-parametric mid band.

Connect your mobile device to the 3.5mm aux input and play along with backing tracks or your favorite songs. Utilize the 1/4" series effects loop to patch in your own stompboxes or rack effects. Output connections include an XLR for linking to a Blackstar U250ACT (available separately), an XLR line output with a ground-lift switch, and a 1/4" headphone jack with an independent level control. A USB audio output allows direct recording to your computer. Speaker emulation for the USB and line/headphone outputs is selectable via a rear-panel button.
