The following is a reprint from Sound House. ■ Bass preamp ■ 2ch specification ■ Controls: BASS, MID, MID FREQ, TREBLE, MASTER / A・B each CHANNEL, MUTE, A/B (foot switch) ■ Dedicated power adapter included ■ Dimensions, weight: 9.5W x 5.3H x 12.5Dcm, 370g ～From the manufacturer's website～ The DUAL BASS STATION is a bass preamp with two inputs, A and B, and independent EQ control sections for each. When using only IN-A (input), it is also possible to switch between the presets of the two EQ controls. The EQ section employs a 3-band EQ to accommodate various genres of music and playing styles. In particular, the mid-range is a parametric equalizer, allowing for detailed sound creation. The parts used in the audio signal path are carefully selected for sound quality, using parts used for audio, boasting sound quality and specifications comparable to high-end audio. The internal circuit voltage is driven at 24 Volts, providing the player with a natural and clear sound without compromising the dynamic range of the bass guitar. The EQ control uses a special curve volume that combines audibility linearity and operability.
