MACKIE FRS2800 Details
More Watts per Dollar, More Sound per Pound
View Mackie’s all new FRS Series power amplifiers deliver phenomenal
power at a price that won’t break the bank—and in a package that
won’t break your back. In fact, each weighs just 22 pounds or less. Featuring
our legendary Fast Recovery circuitry, the FRS Series cranks out clean, undistorted
sound and the ultimate in punch and clarity—even when pushed to the limit.
Each model features a high-current switching power supply that is super-efficient,
and also ultra-lightweight, so you get maximum power with minimum load-in strain.
Sophisticated protection ensures your FRS will always perform reliably, and
that it will stay with you for the long haul. Stack them up against any competitor,
and you’ll see, the FRS amps are simply the highest performing power amps
in their class.
Fast Recovery, Fast Response
FRS amps feature sophisticated Fast Recovery circuitry for the cleanest sound
around. At Mackie, we know that most folks run their amps right up to clipping
levels, so we design our amps to handle this kind of real-world (ab)use. What
we came up with is circuitry that allows the FRS amps to deliver ultimate power,
without sacrificing sound quality. When you overdrive an amp with a traditional
“negative feedback” design into clipping mode, it creates a feedback
loop whereby even once you remove the input signal, the sub-stages of the circuits
remain in saturation mode, causing all sorts of nasty harmonic distortion. The
Fast Recovery technology in the FRS amps ensures all these sub-stages stay out
of saturation, so even when the amp is driven into clipping mode, it instantly
recovers, avoiding the “latching” phenomenon altogether. The result
is ultra-clean, distortion free sound. Read more.
Ultra-Efficient, Lightweight Power Supply
The resonant switching power supply in our new FRS amps provides many sonic
and practical advantages. Being much more compact and weighing considerably
less than a conventional linear supply, it helps make our FRS amps super lightweight
and ultra-portable. And while switching supplies are becoming more and more
popular these days due to their more compact topology, not all switching power
supplies are the same.
Many of our competitors use switching power supplies that employ “hard
switching.” With this design, at switching, voltage is present across
the transistor and current is running through it, generating “glitch”
energy that can cause unwanted noise in the form of Radio Frequency Interference
(RFI), as well as excess heat. The FRS power supply employs “soft”
switching. The soft switching design includes a resonant tank that allows the
power transistors to switch at zero current and zero voltage. This design ensures
that when the transistors switch, very little heat or errant energy is generated,
so the FRS amps run quiet as a mouse, and cool as a cucumber. This not only
means better sound, but longer life. The resonant switching power supply operates
more efficiently than other designs, too, allowing it to provide large bursts
of power more quickly.
Complete Protection Circuitry
SheildFRS amps come with complete system protection. We spent hours conceiving
of all the possible what-if user scenarios, imagined all possible failure modes,
then designed elaborate protection circuits to ensure that pretty much no matter
what you do to our FRS amps, they will endure. Built into every FRS amp is a
defeatable clip limiter plus short, under-impedance, over-current and thermal
protection.
The power supply also includes real-time monitoring circuitry that keeps track
of operating conditions in order to prevent over load failure. The circuitry
“checks” the operating temperature, takes into account the maximum
current, then manages the power supply accordingly, reducing the power if necessary
to protect the power supply and amplifier. As a result, our FRS amps can actually
throughput more power than our competitors’ models with the same power
rating.
Many of our competitors rate power by “music power,” not sine wave
power. If you drive some of our competitors’ amps using sine wave power
at their supposed power rating, the amp will overload and “burn up.”
Because of our protection circuits, under the same conditions, this simply won’t
happen to FRS amps.
It’s never a good idea to overdo it with your amps, and we’re certainly
not encouraging it, but in the chance you do push them beyond their limits,
we’ve built the FRS amps to take it.
The Most Portable Powerhouse in its Class
GrannyDespite being heavy on power, our FRS amps are the lightest Mackie amplifiers
EVER. Other amps in their class either weigh a ton, or don’t deliver on
wattage. Thanks to the design of our super-lightweight and sophisticated switching
power supply, we saved on the pounds, without sacrificing on performance. FRS
amps bring Mackie build and sound quality to rigs on the go, for maximum power
and portability. Now you can get all the wattage you need, and load in and out
with ease.
Ultimate Performance, Ultimate Value
Built Like a Tank With FRS amps, in one lightweight package, you get the ultimate
in performance, reliability and affordability. More powerful and quieter than
others in their price range, FRS Series amps satisfy even the most demanding
systems, while demanding little strength to transport. Their “built-like-a-tank”
construction and Mackie reliability mean the FRS amps will withstand the rigors
of the road, and perform flawlessly during gigs—for years and years. Plus,
we’ve designed the FRS amps to function optimally with Mackie Precision
Passive loudspeakers—match your FRS amp to loudspeakers from the Mackie
C or S Series, and you’ve got a perfectly integrated, powerhouse sound
reinforcement system.
