🎤 PEAK Reference Series Stage V Mammoth Karaoke System – Model PK-SYS-765

The Pinnacle of Power, Precision, and Performance

Step into the future of karaoke excellence with the Peak Reference Series Stage V Mammoth — a masterpiece of engineering that redefines what home performance can sound and feel like. Designed for the passionate singer, the discerning audiophile, and the entertainer who settles for nothing less than perfection, the PK-SYS-765 transforms your living space into a professional stage.

🔊 Professional-Grade Sound, Uncompromising Quality

Every element of the Mammoth has been crafted for clarity, control, and emotional impact. The system’s centerpiece — the Mammoth Reference Speakers — features massive 12-inch low-frequency woofers built from high-rigidity fiber-reinforced composites, delivering deep, thunderous bass with zero distortion.

The horn-loaded midrange driver projects vocals with commanding presence and live-stage realism, while the precision tweeters offer beautifully extended highs that shimmer with detail. Rear-mounted professional SpeakOn connectors ensure maximum signal integrity and long-term durability — the same standard used in world-class stage systems.

Finished in hand-brushed piano black with metallic trim and protective acoustic mesh, the Mammoth speakers are not only powerful — they’re visually stunning, making a bold statement in any home or studio setup.

🎤 PartyHub Wireless Microphones – Intelligent, Clear, and Reliable

Included in the PK-SYS-765 are the revolutionary 2026 PartyHub Wireless Microphones, Peak’s latest innovation in vocal clarity and convenience. Built with precision-milled aluminum housings, these mics feel solid, balanced, and ready for the spotlight.

They feature advanced FBX Feedback Eliminator Technology, which actively detects and suppresses unwanted squeals or howling — protecting your performance and ensuring a smooth, comfortable listening experience for everyone, including children, elders, and pets.

Each microphone charges effortlessly in its magnetic docking cradle, keeping them ready at all times. No cables, no clutter, no waiting — just plug in, power up, and perform.

🎚️ Advanced Audio Control with DSP & Key Changer

The Reference Series amplifier brings audiophile-grade DSP processing to your fingertips. The Digital Signal Processor refines and smooths vocals in real time — balancing tone, eliminating harshness, and adding natural warmth that flatters every voice.

Built for true musicianship, the system includes a Key Changer function, allowing you to instantly shift the pitch of any song to match your range. Whether you’re a trained vocalist or a first-time performer, you’ll always find your perfect key.

With separate volume, echo, treble, bass, and delay controls, you have complete command over your sound — from intimate ballads to powerhouse rock anthems.

đź’Ž Premium Connectivity & Integration

The PK-SYS-765 offers seamless connectivity with both modern and classic setups:

Bluetooth for effortless streaming from phones, tablets, and smart TVs

Digital Output & Fiber-Optic Input for true high-fidelity sound

Line-In / Line-Out for home theatre or professional mixer integration

Multiple Sound Modes to tailor your experience to any environment

This is a system that adapts to you — whether you’re running a dedicated karaoke lounge, a home entertainment center, or a professional event setup.

đź–¤ Design, Build & Presentation

From the moment you unbox it, the Mammoth feels premium. Each component is individually packaged and foam-formed for ultimate protection during transit. The included Peak heavy-duty stands provide optimal speaker height and stability, allowing the sound to project perfectly across any room.

Every detail — from the precision laser-etched Peak branding to the custom-tuned internal damping — speaks to craftsmanship and dedication. The Reference Series isn’t just another karaoke system; it’s a statement piece for those who demand the very best.

✨ Versatility Meets Performance

From cozy family nights to large social gatherings, the Stage V Mammoth adapts seamlessly.
