FLUO™ M500

FLUO™ M500

More power, more speed, less resistance.

The FLUO™ M500 represents the ultimate mono block power amplifier from FLUO™, each housed in its own chassis. Two separate mono block amplifiers are needed to drive both left channel and right channel of your loudspeakers, individually and independently for the greatest performance level. The M500 have individual dedicated mains transformers, delivering high power to both loudspeakers, which are uneffaced by left or right channel demand. Each feature FLUO’s unique Single Die metal-oxide-semiconductor field-effect transistor to deliver musical accuracy across the entire music frequency range.

M500 will deliver 500 W into an 8 Ohm loudspeaker load,1’000 W into a 4 Ohm loudspeaker load and 2’000 W into a 2 Ohm loudspeaker load, this final figure being slightly reduced to 1’800 W due to the mains fuse required.

Therefore, you will hear pure, non-distorted audio, allowing music to flow without compromise, so that your musical enjoyment spans full frequency range with minimum distortion and maximum dynamics.

The brand styling and industrial design of the FLUO™ chassis also reduces resonance frequencies. The chassis design, heat sink fins and top of the product diffuse sound waves, even beyond 20 kHz. The carefully considered dimensions act as sound diffusers, and the front panel also acts to diffuse any transmitted sound waves. Generally, products with large flat surfaces reflect high-frequency sound, similar to the way a mirror reflects light. Possibly for the first time, FLUO™ reduces these problems, enabling the products function at their best without external compromise.

FLUO’s advanced protection system offers a well-proven system, which detects any signal outside the limits and automatically mutes the input for 1 second to make sure, that you notice the problem. Then the system tests for 1 mS (ms?) to test if the problem still exists. If you have removed the problem, i.e., a frayed loudspeaker wire making a short circuit, the amplifier will automatically play music again.

This innovative circuit checks abnormal high frequencies, voltage, current, phase angle and load.

Technical Specifications

The following data is based upon 230V AC mains power. The idle mains power consumption is 100 Watts per mono block.

Output power into an 8 Ohms resistive load is 500 Watts.
Output power into a 4 Ohms resistive load is 1’000 Watts.
Output power into a 2 Ohms resistive load is 2’000 Watts short-term.

Two 6.3 A slow blow mains fuses in the M500 limit the power consumption at 2’900 Watts long-term. Therefore, using sine wave tones, the long-term power in 2 Ohm will be less than 2’000 Watts.

Automatic audio mute should operational temperatures exceed recommended limits.

Automatic protection system does not allow loudspeaker loads below 1.5 Ohms.

The balanced 3-pin XLR input socket has a 40 kOhm input impedance. The 3-pin XLR socket has Pin 2 as plus, Pin 3 as minus, and Pin 1 as ground.
The RCA unbalanced input has a 20 kOhm input impedance.

Due to strong external electromagnetic fields, which can increase the noise levels, we recommend that only shielded signal cables are used.

Dimensions: 485mm x 270mm x 535mm (W x H x D)


FLUO™ is the ultimate balance of technical precision and sound realisation, where there is no need for anything that isn’t already there. In this context less is absolute.
