20 Using the PowerLight 1.5 X and 1.6 HVX CONNECTING INPUTS These models are designed for use with an external active crossover for bi-amp applications, as shown here. Connect the crossover's low- frequency output to the input of Channel 1, which is the higher- powered channel of the amplifier .
21 Instead of the "combo" connectors, you can also use the screw terminals for connecting inputs. POWERLIGHT 1.5 X & POWERLIGHT 1.6 HVX Au lieu des connecteurs "Combo," vous pouvez utiliser les bornes pour le branchement des entrées.

23 Use the additional connections shown for connecting to other amplifiers as needed. If you decide to connect the amplifiers via XLR-to- XLR, you will need either an XLR male-to-XLR male cable, or a male- to-male "gender changer" with a standard shielded XLR cable.
24 T urn-on/turn-off muting The amplifier outputs are muted for a couple of seconds after turn-on, and immediately at turn-off. PROTECTION Short circuit protection The Output Averaging™ circuit protects the output devices from short circuits and stressful loads.
25 Thermal protection A variable-speed fan provides adequate cooling air flow . However , if the heatsink temperature should climb above 90° C, the outputs will mute until the amplifier cools down. Protection thermique Un ventilateur à vitesse variable fournit le courant d’air nécessaire au refroidissement de l’amplificateur .
