4: SPEAKON OUTPUT CONNECTOR
The input loop-through connector enables linking the input to multiple powered speaker
units.
Pressing the preset button will scroll to the next preset from 1 to 5 and back again. When
switched on for the first time, the L6A will be set with the factory default, preset 1.
The XLR Female Input connector is configured as a mono balanced input and should
be connected to the main line level output from your mixer or audio source. For optimal
performance, an audio source with balanced line outputs should be used in order to reduce
possible noise and keep the input stages of the system at acceptable levels, thereby avoiding
clipped input signals.
This cable is NOT supplied with the L6A speaker since the length between the L6A and the
signal source varies from application to application.
Preset 1 – FLAT, 0dB
Pin 1 – Ground
Pin 1 – Ground
Preset 3 – CURVED, 0dB with a -3dB/Q = 0.707 PEQ at 1KHz
Preset 4 – CURVED, +3dB with a -3dB/Q = 0.707 PEQ at 1KHz
Preset 5 – CURVED, +3dB with a -6dB/Q = 0.707 PEQ at 1KHz

The limit LED turns red to indicate when the speaker has reached its maximum SPL
performance and the internal limiters have activated, protecting the speaker and its
electronics.
When connecting the Hybrid L6A to the Hybrid L6P, a maximum of two L6P cabinets may
be connected to one L6A. Connecting more than two L6P cabinets may damage the power
amplifier of the L6A cabinet.
The Speakon Output connector is used when connecting a Hybrid L6P Passive Line Array
Speaker to your system. Only use the 4 core link cable supplied with the L6P for this
connection – the cable is a specialised and tailor-made cable for this application, and the
use of a different cable may cause the system to malfunction or cause damage to the L6A
and L6P.
Only use Powercon Output – Powercon Input cables to connect multiple speaker cabinets.
3 Core cable (Live, Neutral and Earth), min. 1mm diameter / core.
The XLR Male connector is a balanced line connector with an industry standard pin-out
configuration as follows:
TIP: Do not drive the power amplifier beyond this point as it will degrade the audio
quality, which may damage your speakers.
6: LEVEL POTENTIOMETER
The rotary level potentiometer controls the output level/volume of the L6A speaker. It is
good practice to have the level potentiometer at its lowest setting (rotated completely anti-
clockwise) prior to switching the L6A on or off.
The L6A cabinet is internally fused. Should the unit not switch on and it is suspected that the
fuse may have blown, take the speaker for testing to your nearest authorised service centre.
Opening the unit and attempting to repair it without the guidance of a qualified technician is
dangerous, as high voltages are present within the circuitry of the cabinet even after the unit
has been switched off.
Usually, when the fuse has blown, it indicates that there are damaged components within the
circuitry of the speaker. Changing the fuse yourself and restarting the speaker may cause
further damage to these components.
DO NOT attempt to bypass the fuse in any manner by bridging the fuse with a solid conductor.
FUSE
3 core cable (Live, Neutral and Earth), minimum 1mm diameter/core.
