Blaze Audio PowerZone 504 UNI — 500W 4-Channel Installation Amplifier (Universal Voltage)

The Blaze Audio PowerZone 504 UNI is a 4-channel commercial installation amplifier delivering 500W total power (125W per channel) — the standard PowerZone series (not the newer Connect networked variant), with universal voltage power supply that auto-accepts 100–240V AC for international flexibility.

How this differs from the Connect 504: Both share the same 500W × 4-channel power architecture and universal low-Z + 70V/100V output design. The Connect adds network control via the PowerZone Control web app, while this standard PowerZone uses front-panel controls and a more straightforward setup workflow. Choose the standard PowerZone where remote/web-based control isn't required.

Specifications:

• Channels: 4
• Power: 125W per channel × 4 = 500W total
• Output modes: low-Z (4/8Ω) or 70V/100V (selectable per channel)
• Power supply: Universal 100–240V AC auto-sensing ("UNI")
• Class-D amplification
• Front-panel controls and standard signal processing

Ideal for: Smaller commercial installations — cafes, boutique retail, fitness studios, smaller restaurants — where the venue doesn't need (or want) network-based DSP control. Same audio quality as the Connect series at a simpler operational level.
