use supplied 1/8” stereo mini jack to
RCA jacks to connect to mult-source
preamplifier zone outputs
extend and use to connect
to a subwoofer or external
amplifier in zone 2
switching to HF when connecting to a
subwoofer will improve performance of
speakers
1/8” mono jacks are used
to connect 12VDC trigger
inputs and outputs when
power mode switch is in
down position
Elura amplifiers have an in/out
12VDC trigger. The flexibility to
turn on the entire amplifier or trigger
other devices via an audio signal
offers additional control and auto-
mation options. Easily configure the
amplifiers to activate with a global
12v trigger or in Auto mode using a
sensitive audio sensing circuit.
Controls.
Each stereo zone of the amplifiers
can be adjusted allowing fine tuning
for the zone application. Each zone
offers an EQ switch. The EQ switch
changes the output to the speaker.
FR = Full Range, HP = High Pass
and LP = Low Pass. LP is only
available if RCA connections are
used on that zone. Each amplifier
zone with 1/8” stereo jacks in and
out has FR and HP. Plan your con-
nections by using the amplifier zone
that best fits the room requirement.
Example: If you plan on connecting
a Multisource preamplifier signal,
speakers and a powered subwoofer,
use a zone with 1/8” stereo jacks.
Use the 1/8” stereo out to connect
the subwoofer and select HP to
send only mid and high frequencies
to your speakers.
Automation.
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, identify
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.
Placement / Installation.
Rack-mount ears and hardware are
included with every Elura amplifier.
This allows for table-top or 1U AV
rack-mount installation.
Connections.
All RCA audio connections on the
amplifiers are gold-plated, for
superior, non-corrosive, and long-
lasting performance. The removable
speaker connectors offer easier
wiring, faster installation, and
troubleshooting. Speaker wire up to
14 AWG work best with these type
of connectors. A detachable fused
EIC grounded power cable defeats,
noise, simplifies troubleshooting and
adds protection needed.
Some stereo zones use 1/8” stereo
jacks instead of RCA connections.
The smaller space taken up by the
stereo connection offers an in and
out preamplifier connection for add-
ing additional amplifiers, speakers or
subwoofers in each zone.
Input Options.
The amplifiers offer a bus input with
a loop output as well as channel
specific inputs. Installers have the
option to expand the zone amplifier
beyond only two channels, taking
one stereo input signal and
distributing it to up to a max of 6 or
12 stereo zones of audio pending
the model. They also have the op-
tion of using each amplifier channel
independently for multi-zone / multi-
source or home theater applications.
Audio Modes.
Elura multi-channel amplifiers are
organized into stereo pairs and each
pair has the option of being bridged
into 1 higher wattage mono channel.
Being able to bridge channels allows
an installer to use more power in
larger rooms or in outdoor spaces
to provide the optimum sound levels
and or coverage. Note, when in
Bridged Mode the amplifier channel
must be used only with an 8 Ohm
speaker.

Low Impedance Design.
Each Elura amplifier channel is
stable down to 4 ohms. This design
allows for a pair of 8-ohm speakers
to be connected to each channel.
This feature is ideal for larger areas
requiring more coverage.
