HARTKE HA-2500

The Hartke HA2500 Bass Amplifier is a rackmountable 250W bass amplifier designed to amplify passive and active bass guitars in live performance and recording environments. The HA2500 features two pre-amplification input knobs to allow custom blending of tube and solid state tone, and a 10-band graphic equalization. The amplifier’s dedicated preset button allows you to set an equalization curve, and 2 adjustable contour knobs are designed to provide you with more sound-shaping possibilities.

The built-in compressor allows you to smooth out volume differences between notes. The amplifier also features LEDs that show you the settings of the graphic equalizer in low-light environments as well as a two-color LED that continuously shows the status of the compression circuitry in response to your playing. A ground lift switch is provided to prevent hum or buzz from entering the signal, and a pre/post switch allows the direct signal to be derived either before or after equalization.
