Microlynx M0070 Professional Double Bass Preamp
‐User Guide‐
Overview
The Microlynx M0070 double bass preamp was designed by a professional electronics engineer and
bassist to meet the specific requirements of performing double bassists who need their instrument to
be amplified. The design goal was to make the best product on the market today, and we think we
have succeeded.
The M0070 has best in class distortion, noise, headroom and transient response. If you want the clean,
natural, distortion‐free sound of your bass, you can't get a better preamp than the M0070.
The M0070 is designed to mount under the tailpiece. Its light weight wood enclosure construction make
it acoustically transparent, so it doesn't alter the natural frequency response of your instrument.
Advantages of a Preamp
Most modern piezo pickups are capable of providing a fairly strong output signal, so why do you need a
preamp? There are two reasons: performance and convenience
Performance and sound quality
Piezo transducers are sensitive to capacitive loading. Since instrument cables have a capacitance of
about 25 pF/ft , the longer the cable, the more loading the transducer sees. Increased loading
negatively affects both the level of the signal and the frequency response. The M0070 requires only a
12" patch cable and so has negligible loading on the transducer. With the M0070 you get as close as
possible to the natural sound of the instrument and pickup.
Due to the high output impedance of the transducer, the longer the cable, the more prone everything is
to picking up hum and noise. The output impedance of the M0070 is much lower than that of a
transducer and this greatly reduces the sensitivity to hum and noise pickup.
Convenience
The M0070 is designed to mount inconspicuously under the tailpiece of the bass. All the controls are
easily accessible without having to reach over to an external amp or preamp, which may be some
distance away to avoid feedback.

Summary of Contents for Microlynx Systems M0070

  • Page 1 The M0070 requires only a 12” patch cable and so has negligible loading on the transducer. With the M0070 you get as close as possible to the natural sound of the instrument and pickup.

  • Page 2: Features And Controls

    Features and Controls The M0070 is a full‐featured preamp that has everything you need to manage your amplified sound. The following diagram shows the signal chain: Post Direct Lo-Z Hi-Z 10 M High 0/180 Tone Control pass Gain Rumble Phase...

  • Page 3: Volume Control

    Select switch gives the option to provide a 10 Mohm input impedance when required. Direct Out with Phantom Power The M0070 has an XLR Direct Out to connect it to a PA or recording consol using a balanced microphone cable.

  • Page 4: Operating Instructions

    Low Battery and Clipping Indicator The M0070 has an easily visible red LED that flashes if the signal gets close to clipping level. The gain should be set so that the LED only occasionally flashes. There is still at about 3 dB of headroom before clipping actually occurs.

  • Page 5: Adjusting The Volume

    If the LED remains completely off, you might want to try increasing the gain by turning the Gain potentiometer clockwise. The gain is adjusted to 0 dB at the factory. The noise level of the M0070 is very low, so for most applications it’s better to have a smaller output level than to have distortion.
  • Page 6 If “phantom power” is available the M0070 will automatically cut over to it, eliminating drain to the battery. The green LED will illuminate to indicate that the preamp is running off phantom power.

  • Page 7: Specifications

    Current consumption Less than 5 mA, phone jack output only Less than 15 mA if Direct Out (XLR) output is used Specifications are typical and are subject to change without notice. M0070 Professional Preamp User Guide 1.0 ©2009 Microlynx Systems Ltd.
