The AM450 Professional Power Amplifier is a vocal-optimized 2-channel solution designed for intimate settings and small venues, where speech intelligibility and musical fidelity are paramount. Built on a refined Class H topology, it delivers 2x400W @8Ω and 2x600W @4Ω in stereo mode, plus 1200W @8Ω in bridged mono—all within a compact 2U rack-mount chassis (483x430x90mm). A key focus is enhanced midrange clarity (2-5kHz, the “vocal sweet spot”), making it ideal for vocals, speeches, and acoustic music. With professional connectivity (balanced XLR inputs, SPEAKON outputs) and a lightweight design (16KG gross weight), the AM450 balances performance, portability, and ease of use for residential, hospitality, and small commercial applications.
• Enhanced midrange clarity: Tuned frequency response emphasizes the 2-5kHz range (critical for vocals and speech), ensuring every word is clear—even in noisy environments (e.g., restaurants with ambient chatter, wedding receptions).
• Low distortion: <0.05% THD+N (20Hz-20kHz) preserves vocal nuances, from soft whispers (e.g., wedding vows) to powerful speeches (e.g., corporate toasts), without harshness or muffling.
• Low-noise preamp stage: Reduces background hiss common in vocal amplification, ensuring clean audio for microphones (e.g., wireless handheld mics, lavalier mics for speeches).
• Strong channel separation: >80dB cross-talk reduction keeps vocals isolated from background music, preventing muddling in mixed audio setups (e.g., speech + soft jazz).
• Space-saving 2U chassis: At 483x430x90mm, it fits in small racks or entertainment centers—perfect for home theaters, small venue equipment rooms, or residential audio setups.
• Versatile inputs/outputs: Balanced XLR inputs (20K ohms) work with mixers, microphones, and preamps, while SPEAKON outputs (compatible with standard speakers) ensure stable connections (no loose speaker wires).
• Front-panel controls: Easy-to-access gain knobs and LED indicators (signal, clip, protect) simplify setup and monitoring—no advanced technical knowledge required (ideal for small business owners or home users).
• Efficient Class H topology: Reduces heat output compared to Class A/B amplifiers, ensuring quiet operation (no loud fans disrupting events) and long component life (critical for 24/7 hospitality installations).
• Comprehensive safeguards: Protects against overloads, short circuits, DC faults, and thermal overload—preventing damage to the amplifier and connected speakers (e.g., small PA speakers, home theater surrounds).
• Wide voltage compatibility: Designed for 220V~240V AC (50Hz~60Hz), suitable for most regions without voltage converters (e.g., Europe, Asia, Australia).
• Home theater systems (5.1/7.1): Powers surround sound speakers and a small subwoofer, with vocal optimization ensuring clear dialogue from movies and TV shows (e.g., Netflix dramas, Blu-ray films).
• High-end residential audio: Delivers music for living rooms or home studios, with low distortion preserving the quality of vinyl, streaming, or digital files (e.g., classical music, acoustic guitar recordings).
• Home party setups: Drives small PA speakers and microphones for house parties or family events (e.g., birthday parties, holiday gatherings), with easy controls for non-technical users.
• Wedding receptions: Drives microphones for speeches/toasts and a small PA system for background music, with vocal clarity ensuring guests hear every word (even in noisy reception halls).
• Corporate banquets (50-200 guests): Provides sound for emcees, presentations, and dinner music, with reliable protection handling long event durations (4+ hours) without overheating.
• Community events (local halls): Powers microphones and speakers for town meetings, church potlucks, or school concerts, with compact design fitting in small event spaces.
• Restaurant & lounge audio: Delivers background music and vocal announcements (e.g., table calls, happy hour alerts), with midrange optimization ensuring speech cuts through ambient noise (e.g., dining chatter).
• Retail stores (small boutiques): Powers speakers for background music, with low distortion keeping music pleasant for shoppers and staff (e.g., pop music in clothing stores, jazz in bookshops).
• Small worship spaces (chapels): Drives microphones for pastors or priests and small speakers for hymns, with clear vocal reproduction ensuring the congregation hears sermons and prayers (e.g., 50-100 seat chapels).
Yes. The AM450’s 2x400W @8Ω output powers 5.1 or 7.1 surround sound systems when paired with an AV receiver (for signal routing to multiple speakers). Its vocal optimization enhances movie dialogue (critical for home theater, where clear speech improves viewing experience), while the 20Hz-20kHz frequency response handles sound effects (e.g., explosions) and music (e.g., film scores). The compact 2U size fits in entertainment centers, and low heat output means no loud fans disrupting movie nights.
The AM450 is engineered to enhance the 2-5kHz frequency range—the “vocal sweet spot” where human speech and singing are most intelligible. It uses a tailored EQ curve to boost this range without distorting other frequencies (e.g., bass, highs) and a low-noise preamp to reduce background hiss (common in microphone amplification). Additionally, <0.05% THD+N preserves vocal nuances (e.g., breath control for singers, tone variation for speakers), ensuring clarity even in noisy environments (e.g., restaurant speeches).
The AM450 is designed for small-to-medium spaces: 1) Indoor venues: Up to 500 square meters (e.g., small restaurants, 200-seat conference rooms, home theaters) with 2x400W @8Ω stereo output (paired with 85-90dB sensitivity speakers). 2) Outdoor spaces: Up to 300 square meters (e.g., backyard weddings, small tents) when paired with weatherproof speakers (85dB+ sensitivity). For larger spaces, bridge the amplifier to 1200W @8Ω to power a single high-power speaker (e.g., a small line array module) for extended coverage.
