Controls and Connections
25Hz Level Knobs
The 25Hz Level knob sig- nificantly adjusts the level between 20 and 30Hz by ±10dB. This is an area where 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
Bicolor Amplifier Status Light This
No color: No power. The Summit X is not plugged in.
Blue: Play mode. This indicates the Summit X detects an audio signal and is operating normally.
Red: Standby mode. This indicates the Summit X has detected no audio signal for approximately 15 minutes.
Flashing Red: Safe mode. This indicates if the Summit X’s temperature has exceed- ed nominal operating range or that another error has occured. Normal operation will resume when available. This can also occur after initial plug in or while transitioning to standby mode. This is nor- mal and will clear upon music signal or after entering stand- by mode.

Light Knob
The light control allows the Summit X’s three lights to be turned on and off.
50Hz Level Knobs
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 real environments. This set- ting is dependent on room size and construction, system configuration and personal preference.
Signal Input
These binding posts provide a place to connect the Summit X to your amplifier.
AC Power Connection
Your MartinLogan Summit X speakers use an internal power supply to energize their electrostatic cells and PoweredForce™ woofers, and must be connected to an AC power source.
Diaphragm Charge Status Light This green LED indicates dia- phragm charge status.
No color: The circuit has turned off due to lack of signal for over 15 minutes.
Green: Play mode. This indi- cates the Summit X detects an audio signal and the ESL dia- phragm is charged.
