AC Power Connection
Because your Feature speaker uses an internal power sup-
ply to energize its electrostatic panel and to power the
internal amplifier, it must be connected to an AC power
source. For this reason it is provided with the proper IEC
standard power cords. These cords should be firmly insert-
ed into the AC power receptacles on the rear connection
panel of the speaker, then to any convenient AC wall
outlet (see figure 2 & 3). The Feature integrates a signal
sensing power supply which will switch off after five min-
utes of no music signal, and requires less than two seconds
to recharge the panels when a music signal is present.
Your Feature speaker is wired for the power service sup-
plied in the country of original consumer sale. The AC
power requirements applicable to a particular unit is speci-
fied both on the packing carton and on the serial number
plate attached to the speaker. If you remove your Feature
speakers from the country of original sale, be certain that
the AC power supplied in any subsequent location is
suitable before connecting and operating the speaker.
Substantially impaired performance or severe damage may
occur to an Feature speaker if operation is attempted from
an incorrect AC power source.
WARNING!
The power cord should not
be installed, removed, or left detached
from the speaker while the other end is con-
nected to an AC power source.
Status Light
On the rear connection panel is a status light. This light
indicates the following operation modes:
•
Blue:
The speaker is active and ready to play.
•
Red:
The speaker is in auto standby mode.
•
Flashing Red:
The speaker is in auto-protect mode.
This may occur if the internal amplifier overheats. To
reset the speaker unplug it for 10 seconds.
This also
occurs if the speaker is being used with an incompat-
ible AC voltage (i.e. outside country of original sale).
When using the Line Level connection do not use
the Speaker Level connections at the same time .
For optimal performance, MartinLogan recommends line
level (RCA) connection.
Use Feature’s line level connection to attach any of the fol-
lowing devices (see figure 1):
• Television or computer
• Digital Music Player or docking station
• Receiver / Pre-Amp (using pre-amp outputs)
Connection is achieved by connecting an RCA cable
from the output on the device to the Line Level input on the
Feature. If your output device is not equipped with an RCA
style output connector we recommend using a 3.5mm ste-
reo headphone to dual RCA connector (available at nearly
any electronics retailer).
When using Feature’s Line Level Input, make sure that the
output device’s connection utilizes a variable level control
