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. WARNUNG: ZUR VERMEIDUNG VON FEUER ODER ELEKRISCHEN SCHLÄGEN DAS GERÄT NICHT MIT REGEN ODER FEUCHTIGKEIT IN BERÜHRUNG BRINGEN 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. Das Ausrufezeichen in einem gleichseitigen Dreieck weist den Benutzer auf wichtige Betriebs- und Wartungsvorschriften in den beiliegenden Unterlagen des Gerätes hin.

[. . . ] The choice should be made on the basis of minimum hum. With an unbalanced source, connect the signal to pin 2 and source ground to pin 3 (connecting the signal to pin 3 is not rcommended as this will cause a 180 phase invervion at the amplifier outputs). Note: Improper operation results when only pin 2 or only pin 3 and pin 1 (ground) are used for an unbalanced input. Output Connections 2. SUB/LF "Output" Connector Male 3-pin XLR type controller output connector for the SUB/LF channel; used to drive additional amplifiers. FR/HF "Output" Connector Male 3-pin XLR type controller output connector for the FR/HF channel; used to drive additional amplifiers. Note: When the processed controller outputs are used to drive additional amplifiers, it is imperative that the source amplifier's level controls are set at the same or a higher level. Otherwise, the protection feature is lost for the other amplifiers. C22 Controller Module The C22 loudspeaker controller module is a dual input, dual output controller designed for use in stereo systems having either passive loudspeakers or subwoofers. In these systems, it provides protection for the loudspeakers or subs, as well as high & low pass filters and response shaping. Channel 2 "Processed Output" Connector Male 3-pin XLR type controller "processed output" connector for Channel 2; provides a "looping" controller processed output for use in driving additional amplifiers. Channel 2 "FR/HPF Output" Connector Male 3-pin XLR type controller output connector for the FR/HPF channel; used to drive additional amplifiers. An internal selector switch determines whether this connector provides a full10 Output Connections P2400/P2700 OPERATION MANUAL Loudspeaker Controller Modules 1 2 3 4 5 6 7 MODEL C22 CH 2 OUTPUTS CH 2 INPUT PIN 1 = GND PIN 2 = + PIN 3 = - CH 1 INPUT CH 1 OUTPUTS RENKUS-HEINZ MADE IN USA PROCESSED LOOPING / HPF GROUND LOOPING / HPF PROCESSED range "looping" output or a processed band-limited "high pass filter" output. Refer to Selector Switches on page 12 for further information. Channel 2 Audio Input Connector Female 3-pin XLR type input connector. We recommend the use of pin 2 as "hot" and pin 3 as "neutral". When the amplifier is connected to a balanced source, the shield may either be lifted or connected at the source end. The choice should be made on the basis of minimum hum. With an unbalanced source, connect the signal to pin 2 and source ground to pin 3 (connecting the signal to pin 3 is not rcommended as this will cause a 180 phase inversion at the amplifier outputs). Note: Improper operation results when only pin 2 or only pin 3 and pin 1 (ground) are used for an unbalanced input. The Ground Lift switch is used to separate the signal ground circuit from the amplifier ground circuit and thus, eliminate hum induced by ground loops. In the right position, the input signal ground is electrically connected to the amplifier ground circuit (the chassis). In the left position, only an AC connection is provided between the signal ground and the amplifier ground circuit (the chassis). Female 3-pin XLR type input connector for Channel 1.

As the level increases they should begin to flicker red. [. . . ]
