the brightness of the illuminat-
ed strip to be adjusted.
25Hz Level Knob
The 25Hz Level knob sig-
nificantly adjusts the level
between 20 and 30Hz by

peaks and dips of different
amplitudes often manifest in
real environments. This set-
ting is dependent on room
size and construction, system
configuration and personal
preference.
ESL Signal Input
This set of binding posts pro-
vides a place to connect the
signal that drives the XStat™
ESL transducer.
Woofer Signal Input
This set of binding posts pro-
vides a place to connect
the signal that drives the
PoweredForce™ woofers.
AC Power Connection
Because your MartinLogan
Summit speakers use an inter-
nal power supply to energize
their electrostatic cells, they
must be connected to an AC
power source.

50Hz Level Knob
The 50Hz Level knob sig-
nificantly adjusts the level
between 40 and 60Hz by
±10dB. This is an area where
peaks and dips of different
amplitudes often manifest in

Status Light
The Summit is equipped with a
multi-color LED to indicate the
current status of the woofers.
The following list explains the
meaning of the different colors:
No color: No power. The
Summit is not plugged in.
Green: Play mode. This indi-
cates the Summit detects an
audio signal and has auto-
matically switched into play
mode.
Yellow: Standby mode. This
indicates the Summit has
detected no audio signal for
approximately 5 minutes and
has automatically switched
into standby mode.
Red: Initializing or Safe mode.
This indicates that the Summit
is initializing. This also indicates
if the Summit’s temperature has
exceeded nominal operating
range. If the Summit overheats,
please allow the Summit to
cool and reset it by unplugging
the unit and plugging it back in.
