LD Systems XS 700 - Manual (Page 8)

ConnECtionS, CONTROLS, AND INDICATORS:
6 PARALLEL MODE LED
Lights up if the power amplifier is running in parallel mode (MODE switch on the rear panel in position "Par").
One line input (INPUT A or B) supplies the same signal to both power amplifier channels A and B. If there is a
signal on both inputs, then they are merged into a mono signal.
7 BRIDGE MODE LED
Lights up if the power amplifier is running in bridge mode (MODE switch on the rear panel in position "Bri").
In bridge mode, output stages A and B are connected to a more powerful mono output stage.
IMPORTANT: In bridge mode, the total impedance of the connected speaker system must not be less than 8 ohms.
NOTE: If neither of the two MODE LEDs (PAR or BRI) is illuminated, then the power amplifier is in stereo mode
(MODE switch in middle position "Str").
8 ON / OFF
On / off switch. Before switching the equipment on or off, always set the volume of both channels to minimum.
To avoid switching noise, it is advisable to always turn the power amplifiers as the last components in the signal
path of the sound system on first and off last.
