HA2508 Black 8-Channel Class-D Power Amplifier — 8 × 450W at 4Ω, Compact 1U Design
The Haozhiseng Audio HA2508 Black is an 8-channel Class-D power amplifier built for professional audio installations, multi-zone sound systems, and compact PA applications. Delivering 8 × 250W at 8Ω or 8 × 450W at 4Ω, it brings flexible amplification to a space-saving 1U rackmount chassis.
The black enclosure and matching front panel give the HA2508 Black a clean, consistent appearance in professional equipment racks. Individual channel level controls and clearly arranged status indicators make everyday adjustment and monitoring straightforward.
Key Features
- Eight amplification channels for multiple loudspeaker circuits.
- Flexible output configurations: 8 × 250W at 8Ω, 8 × 450W at 4Ω, or 4 × 800W bridged at 8Ω.
- Black metal enclosure with a textured finish for a professional rack appearance.
- Compact 1U design for installations with limited rack space.
- Class-D amplification for efficient operation.
- Individual front-panel level controls for convenient channel adjustment.
- Channel status indicators for signal, clipping, and mute.
- Integrated protection against short circuits, DC faults, overvoltage, undervoltage, overcurrent, and overheating.
- Separate 110V and 220V versions for different power supply requirements.
Eight Channels, Organized Control
The HA2508 Black provides eight amplifier channels for systems with several loudspeaker groups. Front-panel controls allow users to adjust each channel individually, while the indicator layout helps operators check channel status at a glance.
Paired with suitable external routing and audio processing equipment, it can serve different listening areas in restaurants, retail spaces, conference facilities, and other commercial venues.
Black Finish for Professional Installations
The HA2508 Black combines a black front panel with a textured black enclosure. Its understated appearance fits neatly alongside mixers, processors, and other rack-mounted audio equipment.
The slim chassis makes it practical for permanent AV racks and portable equipment cases where both presentation and space matter.
Flexible Loudspeaker Configuration
Choose the output configuration that suits the connected loudspeakers:
| Operating Configuration | Output Power |
|---|---|
| 8Ω per channel | 8 × 250W |
| 4Ω per channel | 8 × 450W |
| 8Ω bridged | 4 × 800W |
Bridged operation combines channel pairs to provide higher output for compatible loudspeaker loads. Follow the amplifier’s operating instructions for mode selection and speaker wiring.
Clear Audio for Speech and Music
A frequency response of 20 Hz–20 kHz within ±1 dB supports speech reinforcement and music playback. THD+N below 0.1%, measured at 1 kHz and 1W into 8Ω, helps maintain signal clarity.
A signal-to-noise ratio above 109 dB at 1 kHz and channel separation above 70 dB at 1 kHz support low-noise performance and reduced interference between channels.
Integrated Protection
The HA2508 Black includes protection against short circuits, DC faults, excessive voltage, insufficient voltage, excessive current, and overheating. These functions help safeguard the amplifier and connected equipment under abnormal operating conditions.
Voltage Options
The HA2508 Black is available in two separate power supply versions:
- 110V version: 90–135V AC operating range.
- 220V version: 180–265V AC operating range.
Select the appropriate version for your local mains supply when ordering.
