EBS MicroBass 3 басс преamp/DI педалын колдонуучунун колдонмосу

Introduction

The EBS MicroBass 3 is a professional-grade 2-channel preamplifier and DI pedal, meticulously designed by EBS in Sweden. It incorporates advanced technologies derived from the acclaimed HD360 and Fafner II amplifier designs, ensuring exceptional sound quality and versatility. This unit operates at a signal level comparable to a professional mixing console, providing ample headroom for various applications. Its high signal level makes it an ideal preamplifier for use with any type of power ampөмүрлүү.

The MicroBass 3 offers both Clean and Drive channels, which can be run independently, in series, or in parallel. It features dual balanced XLR outputs, allowing simultaneous signal tapping both post and pre-EQ. When the effects loop is configured for stereo mode, these balanced outputs function as dedicated left and right outputs. With an input impedance of 10 Mohms, the MicroBass 3 is compatible with all bass types, including passive, active, and those equipped with piezo pickups. Additionally, it includes a convenient built-in tuner and a compressor, similar to those found in other EBS amplifiers, ensuring consistent and reliable sound performance.

Controls Overview

Familiarize yourself with the various controls on the MicroBass 3 to achieve your desired tone.

• Киргизүү бөлүмү:
  • GAIN (Input): Adjusts the input sensitivity. Use the associated LED to ensure optimal signal level without clipping.
• Таза канал:
  • КОМП: Controls the amount of compression applied to the clean signal.
  • Бас: Төмөн жыштыктагы жоопту тууралайт.
  • ОРТО: Controls the mid-frequency response. This knob often has a frequency selector or sweep for precise control.
  • ҮЧТҮҮ: Жогорку жыштыктагы жоопту тууралайт.
  • МАСТЕР: Sets the overall output level of the clean channel.
• Drive каналы:
  • GAIN (Drive): Controls the intensity of the overdrive/distortion effect.
  • ТИП: Selects different drive characteristics or voicings.
  • ОБОН: Shapes the tonal character of the drive sound.
  • АРШЫРУУ: Mixes the clean signal with the driven signal. Turn clockwise for more drive, counter-clockwise for more clean.
  • ДЕҢГЭЭЛ: Sets the output level of the drive channel.
• Бут өчүргүчтөр:
  • Үнсүз: Toggles the output mute function, useful for silent tuning.
  • ДРАЙВ: Engages or disengages the drive channel.
• Арткы панелдин башкаруу элементтери:
  • GND LIFT: Helps eliminate hum caused by ground loops.
  • POST CLEAN / CHR: A switch that likely affects the signal routing or character of one of the balanced outputs. Refer to the detailed manual for specific functionality.
  • STEREO MODE ON/OFF: A switch to enable or disable stereo operation for the effects loop and balanced outputs.
  • SERIAL ON/OFF: A switch to select between serial or parallel routing of the Clean and Drive channels.

Using the Channels (Series/Parallel)

The MicroBass 3 allows you to run its Clean and Drive channels in either series or parallel configuration. This is controlled by the SERIAL ON/OFF switch on the front panel. In series mode, the signal flows from the Clean channel into the Drive channel. In parallel mode, the clean and drive signals are processed independently and then blended together, offering different tonal possibilities.

Tuner and Compressor

The built-in tuner is activated by pressing the БАСУУ footswitch. The display will show the note being played, allowing for quick and accurate tuning between songs without the need for an external device. The integrated compressor, similar to those found in other EBS amplifiers, provides dynamic control over your signal, helping to even out notes and add sustain. Adjust the КОМП knob on the Clean channel to dial in the desired amount of compression.
