Audibax Akron 4-4800 - 4 x 600 W Digital Power Amplifier (1U, Class D UPDM, 4 channels)

Audibax Akron 4-4800 - 4 x 600 W Digital Power Amplifier (1U, Class D UPDM, 4 channels)

The Audibax Akron 4-4800 is a 4-channel , 1U rackmount power amplifier designed to enhance PA systems and professional installations with maximum efficiency. Its Class D architecture with UPDM modulation optimizes energy performance and maintains signal stability even under demanding loads. It delivers 4 × 600 W into 8 Ω or 4 × 900 W into 4 Ω , and allows for channel pairing to achieve 2 × 1200 W into 8 Ω . With a damping factor >1000 , low distortion , and a flat frequency response from 20 Hz to 20 kHz , it offers precise transient control and clean reproduction of both voice and music.

Professional connectivity includes balanced XLR inputs and Speakon outputs for speakers. It features a limiter and peak management system, forced cooling via two fans, and a switched-mode power supply for continuous operation. Weighing only 4.8 kg and measuring 480 × 50 × 230 mm , the Akron 4-4800 maximizes power density in compact racks for touring, rental, club, and corporate A/V applications.

Main features

• Power : 4 × 600 W at 8 Ω · 4 × 900 W at 4 Ω · Bridge : 2 × 1200 W at 8 Ω.
• Technology : Class D amplification with UPDM (Unipolar Pulse Density Modulation) for high efficiency and stability.
• Response : 20 Hz – 20 kHz with low distortion and high damping factor (>1000) .
• Connectivity : Balanced XLR inputs; Speakon speaker outputs (4 poles) .
• Modes : Stereo, Parallel and Bridge by pairs of channels.
• Cooling : 2 heavy-duty fans.
• Form factor : 19" rack, 1U , 4.8 kg ; size 480 × 50 × 230 mm .
• Switched-mode power supply (SMS) and AC operating voltage 220–230 V · 50/60 Hz.

Product benefits

• High power density in 1U: ideal for mobile racks and rooms with limited space.
• Configuration flexibility : four independent channels or two blocks in bridge, adjusting to tops, monitors or zones.
• Superior sound control thanks to high damping , which improves cone grip in bass and transients.
• Energy efficiency and lower heat dissipation due to its Class D stage with UPDM.
• Reliability for continuous use: limiter, peak management and forced ventilation.

Use cases

• Rental and live : multipurpose racks for tops/monitors, voice reinforcement and music at events.
• Fixed installation : bars, auditoriums, multipurpose rooms and corporate spaces with multiple zones.
• Club/venue : stereo or bridge configuration to cover different speaker formats.
• Backup in existing systems: 1U and 4 channels as a versatile backup stage.

Frequently Asked Questions

• Can I use it at 2 Ω? The manufacturer specifies power ratings at 4 and 8 Ω; for 2 Ω, please refer to the manufacturer's system design and datasheets.
• What speaker connectors does it include? 4-pole Speakon .
• Does it have signal outputs/links? It has XLR inputs for each channel and a signal link depending on the rack configuration.
• Is it compatible with 100V line? No, it's a Low-Z output for low impedance loads (4–8 Ω speakers).

Operating modes and wiring

In Stereo mode , use each channel independently (XLR in → Speakon out). In Parallel mode , one input feeds two channels for passive bi-amping or pairs of speakers. In Bridge mode , combine each pair of channels to obtain 2 × 1200 W into 8 Ω (use correct Speakon cabling and respect polarities). Adjust levels with the front panel controls and engage the limiter when necessary to protect the system.
