[. . . ] BEDIENUNG NUR DURCH QUALIFIZIERTES BEDIENUNGSPERSONAL. CAUTION RISK OF ELECTRIC SHOCK: OPEN ONLY IF QUALIFIED AS SERVICE PERSONNEL To reiterate the above warnings: servicing instructions are for use by qualified personnel only. To avoid electric shock, do not perform any servicing other than that contained in the Operation Instructions unless you are qualified to do so. Refer all servicing to qualified personnel VORSICHT GEFAHR EINES ELEKTRISCHEN SCHLAGES: NUR VON QUALIFIZIEREM WARTUNGSPERSONAL ZU ÖFFNEN Eindrigliche Warnung: Wartungsvorschriften dienen nur der Benutzung durch qualifizieres Personal. Zur Vermeidung eines elektrischen Schlages keine anderen als die in den Betriebsvorschriften beschriebenen Wartungsarbeiten ausführen, es sei denn Sie sind dafür qualifiziert. [. . . ] SUB (Subwoofer) Sense Fail Indicator: This red LED will indicate if the sense line coming from the output of the SUB amplifier has become disconnected. If the sense line becomes disconnected, the controller will mute the output audio for the SUB channel. SUB (Subwoofer) Protect Indicator: This red LED will indicate the operation of the speaker protection circuitry. This LED will illuminate because of any one or combination of the following reasons: 1. Excursion protection activated. Status Indicators LOW (Low Frequency) Sense Fail Indicator: This red LED will indicate if the sense line coming from the output of the LOW frequency amplifier has become disconnected. If the sense line becomes disconnected, the controller will mute the output audio for the LOW channel. LOW (Low Frequency) Protect Indicator: This red LED will indicate the operation of the loudspeaker protection circuitry. This LED will illuminate because of any one or combination of the following reasons: 1. Excursion protection activated. MID (Midrange Frequency) Sense Fail Indicator: This red LED will indicate if the sense line coming from the output of the MID frequency amplifier has become disconnected. If the sense line becomes disconnected, the controller will mute the output audio for the MID channel. MID (Midrange Frequency) Protect Indicator: This red LED will indicate the operation of the louspeaker protection circuitry. Whichever pin is selected as hot, select the same pin on the output connectors as hot. This input signal comes from the output of the mixing board. SUB/LF (Subwoofer / Low Frequency) Out: This male XLR connector provides the low audio channel output signal. Its output is electronically balanced with pin 1 as chassis ground. Either pin 2 or pin 3 can be used as hot. Use the same pin for hot as was selected on the input connector. This output connects to the input of the low channel amplifier. FR/HF (Full Range / High Frequency) Out: This male XLR connector provides the high audio channel output signal. Its output is electronically balanced with pin 1 as chassis ground. Either pin 2 or pin 3 can be used as hot. Use the same pin for hot as was selected on the input connector. [. . . ] You can use either pin 2 or pin 3 hot on the input provided you follow the same convention on the output audio connectors. Pin 1 is chassis ground and its use is optional. Whether to connect pin 1 or not will depend upon your application. Use the method which minimizes system hum. [. . . ]
