Erklärung der graphischen Symbole Der Blitz mit nach untenzielendem Pfeil in einem gleichseitigen Dreieck weist den Benutzer auf das Vorhandensein einer unisolierten, "gefährlichen Spannung" im Gehäuse hin, die stark genug sein kann, einer Person einen gefährlichen elektrischen Schlag zu versetzen. The exclamanation point, within an equilateral triangle is intended to alert the users to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. Das Ausrufezeichen in einem gleichseitigen Dreieck weist den Benutzer auf wichtige Betriebs- und Wartungsvorschriften in den beiliegenden Unterlagen des Gerätes hin. CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN VORSICHT GEFAHR EINES ELEKTRISCHEN SCHLAGES NICHT ÖFFNEN CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE THE COVER. UM DAS RISIKO EINES ELEKTRISCHEN SCHLAGES ZU VERMINDERN, ABDECKUNG NICHT ENTFERNEN. 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. [. . . ] FR/HF (Full Range / High 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. Thermal protection activated 10 X12 · X14 · X24 OWNER'S MANUAL . The front panel for the X14 controller is shown below in Figure 6. X14 ON POWER LOUDSPEAKER CONTROLLER SUB LOW MID HIGH SENSE FAIL PROTECT SENSE FAIL PROTECT SIGNAL SENSE FAIL PROTECT SENSE FAIL PROTECT MODEL X14 Figure 6: X14 Front Panel Signal Indicator: This green LED will indicate if an audio signal is present at the input of the controller. 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. This LED will illuminate because of any one or combination of the following reasons: 1. Thermal protection activated. HIGH (High Frequency) Sense Fail Indicator: This red LED will indicate if the sense line coming from the output of the HIGH frequency amplifier has become disconnected. If the sense line becomes disconnected, the controller will mute the output audio for the HIGH channel. HIGH (High Frequency) Protect Indicator: This red LED will indicate the operation of the louspeaker protection circuitry. This LED will illuminate because of any one or combination of the following reasons: 1. Thermal protection activated. 11 X12 · X14 · X24 OWNER'S MANUAL Rear Panel Features AC Receptacle / Fuse Holder: This receptacle accepts an IEC 320/CEE-22 AC power connector. A line cord with the appropriate matching connector is supplied with the controller. [. . . ] This will allow space for the heat to escape from the amplifier and also reduce the coupling of AC hum from the amplifier into the controller. Always support the rear of the controller chassis in the rack especially if used in a portable application. Balanced and Unbalanced Cabling: The inputs and outputs for the controllers are electronically balanced and use standard XLR type connectors. You can use either pin 2 or pin 3 hot on the input provided you follow the same convention on the output audio connectors. [. . . ]
