Audibax Akron 2-2400 - Class D (UPDM) 2×600 W at 8 Ω digital power amplifier in 1U rack

Audibax Akron 2-2400 - Class D (UPDM) 2×600 W at 8 Ω digital power amplifier in 1U rack

The Audibax Akron 2-2400 is a 2-channel, 1U rackmount digital power amplifier designed for professional installations and rental applications requiring high power with maximum efficiency. It incorporates state-of-the-art UPDM (Unipolar Pulse Density Modulation) technology for stable, low-distortion signal delivery, while maintaining low power consumption and a lightweight chassis. It offers 2 x 600 W into 8 Ω , 2 x 900 W into 4 Ω , and 1200 W in bridged mode into 8 Ω , with a frequency response of 20 Hz–20 kHz , THD+N < 0.005% , and a signal-to-noise ratio ≥ 112 dB . Professional connectivity includes balanced XLR inputs , cascaded XLR Link outputs , and Speakon outputs , as well as selectable Stereo, Parallel, and Bridge modes from the rear panel. It features a damping factor > 1000 and a slew rate. 50 V/µs and fan cooling complete a stage prepared to authoritatively drive low impedance speakers in PA, monitoring and sound reinforcement systems.

• Controlled and defined sound: low distortion and high damping to firmly control speaker movement.
• Configuration flexibility: Stereo, Parallel and Bridge modes to adapt the stage to different loads and system designs.
• Professional deployment: Standard XLR/Speakon connectors and Link output for rapid cascading signal distribution.

Use cases

• Main PA in corporate events, halls and theaters with low impedance (low-Z) speakers.
• Stage monitors and side-fills in compact touring configurations.
• Fixed AV installation (clubs, gyms, temples, auditoriums) with 19" racks

Frequently Asked Questions

Does it support 4 Ω per channel?
Yes, it delivers 2×900 W at 4 Ω in stereo mode.

Can I use it in bridge mode at 4 Ω?
No, the specified Bridge mode is 8 Ω . Respect the minimum load indicated by the manufacturer.

What connectors does it use?
Balanced XLR inputs, XLR link unaffected by gain control, and Speakon outputs for speakers.

What is the ventilation like?
It has 1 fan with airflow to keep the temperature within safe ranges.

Connectivity and modes

• Stereo: two independent channels with dedicated gain control.
• Parallel: the same input channel feeds both output modules (pseudo-stereo).
• Bridge: sum of voltages from both modules for 1,200 W at 8 Ω . Requires specific Speakon wiring (labeled on the back).
