Overview

The Samson HighRise Mono Active Mic Booster is a purpose-built inline device that sits between a microphone and a preamp to provide a clean gain boost of either +20dB or +30dB. It addresses a common challenge in recording: dynamic and passive ribbon microphones often produce relatively low output signals, forcing preamps to work harder and introducing noise. By boosting the signal before it reaches the preamp, the HighRise allows you to achieve a cleaner, quieter recording chain. The unit draws its power from standard 48V phantom power supplied by your audio interface or mixer, so there are no batteries to manage.

Beyond pure gain, the HighRise includes a selectable low-cut filter and high-frequency lift, giving you basic tone-shaping options right at the source. A particularly valuable feature for ribbon microphone users is the built-in phantom power blocking, which prevents potentially damaging voltage from reaching the sensitive ribbon element. The all-metal, impact-resistant housing is built for the demands of both studio and location work, and the compact inline form factor keeps your setup tidy without adding significant weight or bulk to your mic stand.

Pros & Cons

👍 Pros

  • Selectable +20dB or +30dB gain provides flexibility for different microphone output levels
  • Built-in phantom power blocking protects sensitive passive ribbon microphones from damage
  • All-metal, impact-resistant construction stands up to regular studio and field use
  • Compact in-line design adds minimal bulk between the microphone and the cable run
  • Includes selectable low-cut filter and high-frequency lift for basic signal shaping

👎 Cons

  • Mono design means you need two units if you are running a stereo microphone pair
  • Requires 48V phantom power from your interface, so it cannot be used with equipment that lacks phantom power
  • Only benefits dynamic and passive ribbon mics — active microphones and condensers generally do not need the additional gain

Frequently Asked Questions

The HighRise is designed for dynamic and passive ribbon microphones that need a gain boost to produce a strong, clean signal at the preamp.
Yes, the HighRise blocks phantom power from reaching your ribbon microphone, preventing potential damage to the delicate ribbon element while still drawing the phantom power it needs to operate its own active circuitry.
The HighRise features a selectable switch that lets you choose between +20dB or +30dB of gain depending on how much boost your signal needs.
The HighRise is powered by 48V phantom power supplied from your audio interface or mixer, so no batteries or external power supply are needed.
Yes, the HighRise includes a selectable low-cut filter and a high-frequency lift, allowing you to shape the signal before it reaches your preamp.
