Funktion-One FFA6004 Amplifiers for Sale | 2 × F60Q Ex-Install Units

The Funktion-One FFA6004 amplifiers for sale are offered here as 2 × F60Q four-channel professional power amplifiers, manufactured by Full Fat Audio (FFA) and Funktion-One branded. Both units are ex-install amplifiers in good condition and perfectly working, making this pair particularly relevant for professional Funktion-One system owners, clubs, venues and PA companies looking to expand an existing amplifier inventory.

The relationship between these models is worth highlighting: Funktion-One’s F-Series amplifiers were manufactured by UK amplifier specialist Full Fat Audio to Funktion-One specifications, and the F60Q is the Funktion-One-branded four-channel model associated with the FFA6004 platform. Funktion-One documentation confirms that its F-Series used FFA Class-D technology and switch-mode power supplies.

What Is Included in This FFA6004 Package?

This listing contains two matching amplifier units:

The 4 × 1500 W at 4 Ω rating for the F60Q is also documented in Funktion-One-related technical material.

Two Funktion-One F60Q Amplifiers

Instead of a single amplifier, this package provides 2 × F60Q units.

That gives a professional buyer a total of eight amplifier channels across the pair.

For companies building multi-way systems, having eight channels available from two matching amplifiers can make rack planning more straightforward. Furthermore, keeping both units on the same amplifier platform simplifies operation compared with combining several unrelated amplifier models.

4 × 1500 Watts at 4 Ohms Per Amplifier

Each F60Q/FFA6004 provides a stated:

4 × 1500 W at 4 Ω

Therefore, the two-amplifier package provides eight channels with substantial output capability when operated within the appropriate system configuration.

The F60Q is also documented at approximately 800 W per channel into 8 Ω.

This gives system designers flexibility when matching the amplifiers with appropriate professional loudspeakers.

Full Fat Audio Engineering with Funktion-One Branding

An important part of the history of these amplifiers is the relationship between Full Fat Audio and Funktion-One.

Funktion-One states that its F-Series amplifiers were manufactured by Full Fat Audio to Funktion-One’s specifications. The platform uses switch-mode power supplies together with Class-D amplification.

Full Fat Audio also notes that Funktion-One selected FFA to supply OEM amplifier versions for professional installations.

Therefore, the Funktion-One branding on these units is not simply an aftermarket badge. The F-Series formed part of Funktion-One’s professional electronics offering.

Ex-Install Amplifiers in Good Condition

Both amplifiers are described as ex-install units.

This means they previously formed part of a fixed professional installation rather than being presented as new equipment.

The units are currently stated to be:

Perfectly working and in good condition.

For buyers of used professional amplification, operational condition is particularly important. Ex-install equipment can also be attractive to buyers who prefer equipment that has spent much of its service life in a fixed system rather than moving continuously between touring productions.

Funktion-One FFA6004 Amplifiers for Sale for Existing Systems

These Funktion-One FFA6004 amplifiers for sale can be particularly useful for businesses already operating compatible Funktion-One equipment.

The FFA6004 platform has historically been used in professional Funktion-One installations. Full Fat Audio’s own published project material documents FFA6004 amplifiers powering Funktion-One systems in professional venues.

For an existing system owner, additional matching amplifiers could therefore serve as expansion units, replacement equipment or backup inventory.

Eight Amplifier Channels Across the Pair

With two F60Q amplifiers, the package provides:

Amplifier 1: Channels 1–4
Amplifier 2: Channels 5–8

That creates eight independent amplifier channels for appropriately designed professional systems.

This can be useful for multi-way configurations where different loudspeaker sections require separate amplifier channels and processing.

However, the exact assignment should always follow the requirements of the loudspeaker system and processor configuration.

Class-D Amplifier Technology

The F-Series uses Class-D amplification technology, which allows substantial amplifier output without requiring the size and weight associated with many traditional high-power amplifier designs.

Funktion-One’s documentation specifically describes its F-Series as using FFA Class-D technology and switch-mode power supplies.

For fixed installations and professional racks, this architecture can provide useful power density across multiple channels.

Designed for Professional Sound Applications

The F60Q/FFA6004 platform was developed for professional sound reinforcement rather than domestic hi-fi.

These two amplifiers can therefore be considered for suitable applications such as:

• Funktion-One sound systems
• Nightclubs
• Professional venue installations
• Live music systems
• PA rental
• Event production
• Theatre sound
• Multi-way professional systems
• Existing Funktion-One amplifier racks
• Backup professional amplification

The connected loudspeakers, impedance and processing must still be matched correctly.

A Useful Pair for Club Sound Systems

Four-channel amplification is particularly useful in multi-way professional club systems.

Different amplifier channels can power separate sections of an appropriately configured PA, while external loudspeaker management provides the required crossover, limiting, EQ and delay.

With two F60Q amplifiers available, a system designer gains eight amplifier channels from matching units.

This can make the package especially relevant for clubs replacing older FFA/Funktion-One amplification or expanding an established system.

Original Funktion-One F-Series Platform

For buyers specifically searching for older Funktion-One amplification, the F60Q has historical significance within the brand’s electronics range.

Funktion-One’s earlier F-Series included the F60Q among its four-channel amplifier offerings, while its current F-Series lineup has evolved to newer models.

Therefore, these amplifiers should be presented as established professional ex-install equipment, rather than being confused with the manufacturer’s newest amplifier generation.

Correct Processing Remains Important

A powerful amplifier alone does not determine how a professional Funktion-One system should operate.

Correct loudspeaker management may involve:

• Crossover filters
• Limiter configuration
• Channel gain
• Delay
• Polarity
• System-specific settings

Consequently, buyers should configure these amplifiers according to the requirements of the loudspeakers they intend to drive.

Why Consider Two Matching F60Q Amplifiers?

Buying two matching units instead of unrelated amplifiers can make professional system management easier.

The pair provides consistent:

• Amplifier architecture
• Channel configuration
• Output capability
• Rack workflow
• System familiarity

For an installer or venue already familiar with F60Q/FFA6004 amplifiers, this can make integration considerably simpler.
