introduction
The Myryad MA 120, 240 and 360 Power
Amplifiers have been designed to offer
a combination of high quality sound
reproduction and simple yet elegant styling.
They can be used to provide power for high
quality stereo systems when partnered by a
suitable preamplifier such as Myryad’s MP
100, or with a Myryad integrated amplifier in
bi-amp or tri-amp systems. They can also be
used, in combination (e.g. one MA 240 Stereo
Power Amplifier plus one Myryad MA 360
Three Channel Power Amplifier), to power a
full-surround music or Home Cinema sound
system of the highest quality.
The MA 120 and MA 360 have unbalanced
line inputs plus directly linked line outputs,
all on RCA phono sockets.
The MA 240 also has unbalanced line inputs
plus directly linked line outputs, all on
RCA phono sockets but it in addition it has
balanced line inputs on professional quality
3-pin XLR sockets. Furthermore, the two
amplifier channels may be switched to
bridged-mono mode for increased power
output into a single 8Ω loudspeaker using a
rear panel switch.
All Myryad M-Series Power Amplifiers may
be controlled remotely via the My-Link
communications bus when used with other
Myryad M series products. The My-Link
allows remote control of standby and mute
functions. In addition to this, the MA 240
and MA 360 power amplifiers may be
switched into or out of standby remotely
using their DC trigger inputs.

• Stereo operation, delivering 2 x 60 watts
into 8Ω loudspeakers
• One MA 120 with an MI 120 Integrated
Amplifier in a bi-amplifier system
• Two MA 120s with an MP 100

• Up to ten MA 120s and one MI 120 or
MP 100 in a multi-room system
MA 240 applications include:
• Stereo operation, delivering 2 x 120 watts
into 8Ω loudspeakers
• High power stereo operation with two
MA 240s – able to deliver 2 x 400 watts
into a minimum 8Ω load
• Stereo bi-amplifier operation with two
MA 240s, each delivering 2 x 120 watts into
8Ω loudspeakers
• Use in conjunction with the MA 360 Three
Channel Power Amplifier, delivering five
channels at 120 watts into 8Ω in Home
Cinema systems of the highest quality
MA 360 applications include:

installation and
safety notes
This amplifier generates a modest amount
of heat and thus requires ventilation. Do
not place it on a rug or other soft surface
into which it could sink, obstructing the air
inlets in its underside. Do not allow papers
or cloth to obstruct the ventilation grille in
the top cover. The amplifier should not be
installed in a built-in situation such as
a bookcase or cabinet that may impede
the flow of air. If the amplifier is moved
shortly after operation take care not to touch
the heatsinks, which are accessible from
below, as they may be very hot. The amplifier
is designed for use in moderate climates.
