What Is Full Fat Audio and Why Funktion One Chose Them

Full Fat Audio is a British professional power amplifier manufacturer that builds high-efficiency Class D amplifiers for touring, club sound, and installation applications. Their product range is designed for the specific demands of high-SPL professional audio environments where sustained output, thermal stability, and low distortion under continuous load are the non-negotiable requirements.

Funktion One’s decision to specify, brand, and integrate FFA amplifiers into their passive speaker system installations reflects the same OEM logic that governs their use of MC2 Audio amplifiers across other system configurations. The Funktion One brand is placed on an amplifier only when that amplifier has been evaluated and confirmed as meeting the acoustic and technical standard required for their speaker systems. The F60Q designation identifies the specific FFA 6004 variant that Funktion One integrated into their installation packages.

What Is the FFA 6004 F60Q

The FFA 6004 is a four-channel professional power amplifier delivering 6,000W of total output across four independent channels. The four-channel architecture makes it particularly practical in professional PA applications where a single unit can drive multiple speaker zones or handle bi-amp configurations for a stereo passive speaker system from one chassis.

The F60Q variant designation refers to the specific configuration of this unit as integrated into Funktion One’s installation packages. The four-channel output makes the FFA 6004 well suited to driving full-range passive tops and passive subwoofers from a single amplifier chassis, reducing rack unit count and simplifying cabling in permanent installation environments. This is precisely the application it was deployed in before becoming available here.

What Is a Four-Channel Amplifier and Why It Makes Practical Sense

A four-channel amplifier drives four independent speaker loads from a single chassis. In professional PA practice, this architecture reduces the total number of rack units required for a complete amplification solution. Rather than installing two separate two-channel amplifiers to cover four output channels, a single four-channel unit delivers the same total channel count in half the rack space with simpler cabling requirements.

For a stereo bi-amp system, which is one of the most common configurations in professional club and touring PA, a four-channel amplifier is the natural choice. Channel 1 drives the left subwoofer. Channel 2 drives the right subwoofer. Channel 3 drives the left full-range top. Channel 4 drives the right full-range top. Four channels, one chassis, one power connection, one set of signal inputs routed from the processor. This is the configuration the FFA 6004 F60Q was deployed in during its fixed installation life.

What Is a Fixed Install and Why It Matters for Amplifier Condition

A fixed install amplifier is mounted permanently in a rack in a controlled environment from the time of installation. It never travels in touring vehicles. It is never unracked and re-racked repeatedly. It does not experience the vibration, temperature cycling, or mechanical shock of touring use. For electronic components, particularly the capacitors, power transistors, and cooling systems inside a Class D amplifier, a fixed install life is significantly less stressful than equivalent touring use.

Both FFA 6004 F60Q units in this listing come from a fixed installation. That provenance supports the good condition description and explains why units of this age from a fixed install context present better than equivalent touring units would.

Best Applications for the FFA 6004 F60Q

At 1,500W per channel at 4 ohms, each channel of the FFA 6004 is appropriate for passive speaker systems with program power ratings between 800W and 1,200W per cabinet. This includes Funktion One Res 2 Mk1 and Res 2 tops, Void Acoustics Air Series tops, Martin Audio touring tops, and equivalent passive speakers in the professional touring and club installation market. For subwoofer applications, each channel handles single 15-inch or single 18-inch passive subwoofers rated up to 1,200W program.

Technical guidance on FFA 6004 amplifier configuration and speaker pairing is covered at bostonprosounds.com, which provides practical system design references for engineers specifying FFA-based drive solutions. For broader professional PA amplifier comparisons and system integration guidance, sasphonik.com is a useful resource before finalising your amplifier specification.

What to Consider Before Deploying These Units

Both units are confirmed perfectly working in good condition. Good condition at musicconcertevent.com means the units present professionally with normal wear consistent with installation use. Audio performance, protection circuits, and cooling systems have been verified operational. No significant cosmetic or functional issues are present beyond normal installation wear.

DSP processing is required. The FFA 6004 F60Q is a power amplifier only. It requires an external DSP processor for crossover management, EQ, and output limiting. An XTA DP226, XTA DP448, or equivalent four-output processor is appropriate for a bi-amp stereo configuration driven by these units.

The Funktion One OEM branding on these units is original factory branding, not a label applied after the fact. It confirms these amplifiers were specified and integrated by Funktion One as part of an official installation package. This provenance adds value for Funktion One system owners who want OEM-matched amplification and are willing to pay a premium for it.

Why FFA 6004 Amplifiers Hold Their Value

Full Fat Audio builds amplifiers to professional touring standards. The FFA 6004’s four-channel architecture combined with 6,000W total output in a 2U chassis makes it one of the most space-efficient professional amplifiers available in the used market. Engineers who need four amplifier channels in minimum rack space consistently search for the FFA 6004 specifically, which sustains secondary market demand at predictable pricing.

The Funktion One OEM branding on these specific units adds a further value dimension. Funktion One system operators and installers who want OEM-matched amplification actively search for branded FFA units. That specific buyer pool is prepared to pay a premium over generic FFA 6004 listings, which means Funktion One branded units command the upper end of the FFA 6004 resale range consistently.

Fixed install provenance supports condition assessment. Buyers who understand the difference between touring and installation history know that fixed install units age more gracefully than touring equivalents. This context validates the good condition description and supports the asking price against alternatives with unknown or touring-heavy histories.
