D1500 with two indipendent channels, parallel or bridge configurable, fully made with switching technology with output stages in class-D shape. D3000 with four indipendent channels, configurable as two parallel or bridge amplifiers, fully made with switching technology with output stages in class-D shape. When this LED flashes reduce the input signal level of channel 1. When this LED flashes reduce the input signal level of channel 2. Yellow LED illuminates when the channel 1 is in protect mode for one of the following reasons: · The heatsink reaches a temperature above the normal working limit. ⷠThere is a short circuit at the amplifier output wires. Consequently the channel is muted until the reason of fault is removed. Yellow LED illuminates when the channel 2 is in protect mode. Yellow LED illuminates when both the channels are in bridge mode. NOTE: When the amplifier operates in BRIDGE mode SIGNAL, LIMIT and PROTECT LED indicators illuminate simultaneously, the signal is sent to both amplifiers from channel 1 input only and controlled by channel 1 level control only. Air cooling vent: always keep it clear of cables or other objects. Connect the power cord to an electrical outlet complying with the power supply specifications indicated on the apparatus. Be sure your amplifier is turned off before you plug the mains supply cord into an electrical outlet. [. . . ] Tip - hot ring - cold sleeve - ground *note: connect both cold and ground to make cable from balanced to unbalanced *nota: connettere insieme cold e ground per cavi da bilanciato a sbilanciato This is a short extraction of the wide assortment of cables available from PROEL, please visit our website at www. The above table is a short-form of some sound system examples composed of PROEL loudspeakers. These are a few portion of the speaker products in catalogue at the moment of printing. Make sure the mains AC outlet is live (check with a tester or a lamp). [. . . ]
