M-300 Monaural power amplifier
Introduction
Congratulations on your purchase of the Clayton Audio M-300
monobloc amplifiers! Your M300s were made to sound good and to
perform as well as the very best amplifiers on the market. They are a
high-current design that can drive the most demanding speaker loads.
These power amplifiers were designed to produce reference-quality
sound with all the excitement and elegance of live music. The M-300s
were handmade in the USA after years of careful design and testing.
Properly used and installed, these amplifiers will provide you with many
years of trouble-free, high-quality amplification. We hope that you will
take the time to read and look through this owner’s manual before
operating the M-300.

Installation
Please unpack the amplifier carefully in accordance with the enclosed
instruction card. Each monaural power amplifier weighs 87 pounds so
we urge reasonable caution in handling to avoid injury. Please save all
packing materials for future use. Should you need to ship your
amplifier to us, only the original shipping cartons will be acceptable.
Other packing methods might result in serious damage to your precision
amplifiers.
Inspect your amplifier carefully to make sure that it has suffered no
damage in shipping. Consult your dealer if you have any questions.
Do not stack any equipment on top of the amplifiers. Always remember
to power-off and disconnect the amplifiers when moving or handling
them.
Unpacking your new amplifiers
The amplifers are heavy. Use caution when lifiting them after
removing all packing material, or use a friend to assist with lifting
and amplifer placement in your home. Save all packing materials in

the box. Below are photos of the series of steps used to unpack the
amplifier. Please note that we use a special metal protector
blocking the fuse holders, 12 volt trigger switch and remote control
port. We recommend leaving this metal strip on the rear panel until
removal is necessary.

Operation
The Clayton Audio M-300 monoblocs are high-performance class A
amplifiers, conservatively rated at 300 watts per channel into 8 ohms.
They are a no-compromise, wide-bandwidth design which should drive
virtually any high-end speaker load with relative ease. Because the
Clayton Audio M-300s are a class A design, they will run very hot in
normal operation. Make sure to place them in a well-ventilated
location on a stable support. Be careful about touching the tops of the
heat sinks when in operation. Depending on the AC line voltage the
high-bias setting will run at a temperature up to 55 degrees Fahrenheit
above the room temperature. The low-bias setting will only run about 40
degrees above room temperature. Under casual listening conditions, the
low-bias setting will be virtually indistinguishable from the high-bias
setting and will not make the amplifier run as hot. The bias switch can
be set to high when listening critically or at high volume levels. Since the
amplifier is very stable, you can switch between the two bias positions at
any time, even while the amplifier is in operation. See photo below.
