Samson HighRise Mic Gain Booster - In-line microphone preamplifier (+20/+30 dB) with 120 Hz crossover

Samson HighRise Mic Gain Booster - In-line microphone preamplifier (+20/+30 dB) with 120 Hz crossover

The Samson HighRise is an inline microphone gain booster that adds up to +30 dB of clean, transparent gain before your preamp, interface, or mixer, letting you work with low-sensitivity passive dynamic and ribbon microphones without extreme gain settings. It runs on phantom power (P12–P48) but does not pass through to the input , making it safe for passive ribbon microphones . It features a three-position gain switch ( +20 dB , +30 dB , or +20 dB with high -frequency boost for vocal presence) and a 120 Hz Low Cut filter to clean up rumble and noise. Its Class-A design with fully differential input/output preserves a natural signal, and the 14-gauge steel chassis is ready for intensive studio or live use.

Main features

• Selectable gain : +20 dB, +30 dB or +20 dB with high boost (presence).
• Switchable 120Hz Low Cut filter to reduce low frequency noise.
• Ribbon safe : phantom powered but does not transmit to the microphone.
• Class A architecture with bipolar transistors and differential I/O for maximum transparency.
• Construction : 14 ga steel chassis, compact and durable for touring or studio.
• Status : White power/activity LED when receiving phantom power.

Product benefits

• More level with less noise : Boosts the signal before the preamp and allows you to use less gain from the interface/mixer, reducing added noise.
• Optimized for dynamics and ribbons : makes low-output mics useful for podcasts, vocals, soft instruments, or distant recordings.
• Quick Creative Control : High boost for instant presence and 120Hz filter to clean up problematic bass.
• Universal Integration : In-line XLR connector, small size and standard phantom power.

Use cases

• Podcast and voiceover with broadcast-type dynamics that require a lot of gain.
• Soft, acoustic and foley vocals in studio and location sound .
• Live and theater : more headroom and less noise on long chains or tables with little gain travel.

Frequently Asked Questions

• Does it need power? Yes, it requires a phantom power supply (P12–P48) to operate.
• Can I use it with condenser microphones that require phantom power? No. The HighRise blocks the phantom power from reaching the microphone . Use it with dynamic microphones , passive ribbon microphones , or condensers that don't require their own phantom power.
• Does it provide color? Its Class A design and differential I/O are designed to be transparent ; the high-frequency boost and low cut are switchable.
