Hendy Amps Maor Appelbaum Signature Series “The Steamer” Dual-Channel Preamp

The Steamer is a two-channel high-voltage solid-state preamp that delivers monstrous tone through deceptively simple controls. Designed in collaboration with mastering engineer Maor Appelbaum, this 1U rack unit packs complex circuitry into an intuitive interface focused on capturing performances without distraction. High-voltage MOSFET-based amplification provides power and depth that competes with the industry’s finest preamps, while transformer-balanced mic inputs and transformerless outputs maintain signal integrity. Independent Gain and Trim controls per channel enable everything from pristine transparency to significant coloration and overdrive, while dedicated DI inputs handle bass, acoustic guitars, synths, and any unbalanced instrument source. The Line Level switch allows reprocessing of DAW tracks through the preamp for warmth and impact on instrument busses, groups, or even mastering applications.

Key Features:

• High-Voltage MOSFET Amplification: Dual-mono solid-state design delivers exceptional power, depth, and headroom through high-voltage circuitry that maintains sound integrity across all gain levels.
• Independent Gain and Trim Controls: Extensive gain range handles demanding microphones, while Trim adjusts output to match downstream gear or pushes the circuit into coloration and overdrive when desired.
• Dedicated DI Inputs: Instrument-level inputs per channel excel with bass guitars, acoustic guitars, electric guitars, synthesizers, and any unbalanced source requiring direct connection.
• Line Level Reprocessing: Switch mic inputs to line level for running DAW tracks back through the preamp, adding warmth and impact to instrument busses, groups, mix bus, or mastering chain.
• Flexible Filtering: Low Cut (high-pass) and High Cut (low-pass) switches clean up recordings by removing unwanted frequencies, usable individually or together for mid-focused sound.
• Complete Signal Management: 48V phantom power, 20dB pad for hot sources, transformer-balanced mic inputs, and transformerless outputs provide comprehensive control over signal flow.
• One-on-One Masterclass Included: Every purchase includes a personal session with Maor Appelbaum covering workflow methodology and integration guidance to maximize your Steamer’s potential.
