Darkglass Electronics B7K V2 Analog Bass Preamp
With the Darkglass Electronics B7K V2 Analog Bass Preamp you get all the features of the original, with the ability to better sculpture your tone: on the low mids you have the option to change the center frequency from 1KHz to 500Hz, and on the high mids you have the option to change the center frequency from 3kHz to 1.5kHz. This will enable you to tailor your absolute dream distortion tone.
The character and core of the Microtubes B7K remains the same, still retaining the powerful dynamic saturation circuit of the B3K and adds a four-band equalizer and a balanced line driver for even greater versatility. Designed for both studio and live use, it will take your direct sound to a whole new level.
Controls
Blend: Mixes the clean input signal with the overdriven signal.
The clean signal remains at unity gain while the volume of the
overdriven signal is set by the Level knob, allowing for fine
control of the blend ratio.
Level: Sets the volume of the overdriven signal.
Drive: Sets the amount of saturation in the overdriven signal.
Grunt Switch: Sets the amount of low frequency content to
saturate by selecting between three different bass boost
levels before the clipping stage.
Attack Switch: Sets the amount of treble content to saturate:
The "Boost" setting emphasizes the treble content extra
clarity and presence. The "Flat" position leaves this register
untouched while the "Cut" position will reduce the amount of
high frequencies being saturated.
Low: +-12dB @ 100Hz
Low Mids: +-12dB @ 1kHz
Hi Mids: +-12dB @ 3 kHz
Treble: +-12dB @ 5kHz
Low Mids Switch: this switch change the center frequency of
the Low Mids from 1kHz to 500Hz.
Hi Mids Switch: this switch change the center frequency of
the Hi Mids from 3kHz to 1.5kHz.
Parallel Output: A passthrough for your input signal, useful
for parallel processing.
Direct Output: A balanced version of the ¼” output, useful for
running into PA’s or studio mixing console.
Power: The B7K V2 has a current draw of 30mA. Only use a regulated 9V DC adapter with a center-negative plug. Due to ecological reasons it does not accept batteries. Warning: Unregulated power supplies and/or higher voltages may result in suboptimal noise performance and even damage your unit, voiding the warranty.
