model # AMP 150/2
high performance amplifier
The M-AMP 150/2 has three power
modes, ON / AUTO / TRIGGERED.
ON = Always ON
AUTO = Signal sensing via audio
TRIGGERED = 12VDC tip positive
Amplifiers produce light noise when
left on. The noise is a light hiss and
is heard when music isn’t playing in
a very quiet room. If you are using
a master switch to turn off power
to your audio equipment, always
on is acceptable. In a louder or light
commercial environment, always ON
may be acceptable. In quiet rooms,
it is suggested to use AUTO or
TRIGGERED options.
Bridging.
Bridging offers the user more power
to the speaker. The comprimise is
that you lose a channel of the am-
plifier and the lowest impedance in
bridge mode is 8 Ω. Bridging is an
excellent way to increase the power
to a pair of larger speaker. The dia-
gram to the left shows an amplifier
connected to a single speaker. For
a pair, you would need two amplifi-
ers and repeat the conenctions for
left and right source outputs and
speaker connections. See the image
to the left for more details.
Amp Volume Settings.
The volume for the amplifier is on the
front panel offer integrated control of
the speaker output for Left / Right.
Auto Power Modes.
Speaker Connections.
The AMP 150/2 has 5-way binding
posts to makeconnecting your
speaker wire easy and secure. The
connector can be used to screw
down onto bare wire, or banana
jacks,spade connectors or pins.
Position and polarity are color
coded and marked to avoid phase
issues. Be sure to follow and main-
tain proper polarity and position.
Preamp Connections.
Preamplified connections are made
using Stereo RCA patch cables.
The AMP 150/2 provides a con-
venient IN and OUT loop. Use the
output to connect to another amp
or other device sharing the pre-
amp source signal. Other high-end
options include using the amplifier’s
built in EQ filters to amplify just the
low frequencies or the high frequen-
cies using the FR/HP/LP switch.

Front Panel LEDs.
The Elura amplifiers have LEDs on
the front panel to indicate the ampli-
fier’s power state and channel
status. The Power LED indicates
the amplifier is ON. There is a LED
indicating the channel state. The
LEDs can be used to identify and
trouble shoot channels that are
not working. If a channel is in fault
mode, power down the amp, identi-
fy and fix the issue. When complete
power up the amp to recheck it has
been resolved.
Power ON = Blue
Power OFF = Red
Channel Normal = Blue
Channel Fault = Red
Channel fault conditions are
shortcircuit, thermal, or overload
failures.

Bi-amping.
Bi-amping your speakers using two
AMP150/2 amplifiers is an excellent
and efficient way to get the most out
of your speakers. In this case, the
frequencies are crossovered in the
amplifier and the speakers drivers are
fed the most power possible directly
to the tweeters and the drivers. Each
speaker is driven by an amplifier
channel bypassing the crossover
components. While this setup can be
a little more complicated, the
performance is top notch!
