User manual NADY CX-23SW

[. . . ] Please read this manual carefully to get the most out of your new unit. Thanks for selecting NADY AUDIO as your choice in crossovers. FEATURES Crossovers provide precise frequency dividing for multiamplified speaker applications, and are valuable tools in many professional live sound uses. The CX-23SW offers 3-way active LOW/MID/HIGH outputs for each stereo channel and a mono subwoofer output. [. . . ] Replace the fuse only with one of the specified type, size, and correct rating. The power supply cord should: (1) be undamaged, (2) never share an outlet or extension cord with other devices so that the outlet's or extension cord's power rating is exceeded, and (3) never be left plugged into the outlet when not being used for a long period of time. Care should be taken so that objects do not fall into, and liquids are not spilled through, the enclosure's openings. Objects have fallen into, or liquid has been spilled onto the product. The product does not appear to operate normally or exhibits a marked change in performance. Do not attempt to service the product beyond what is described in the user maintenance instructions. All other servicing should be referred to qualified service personnel. 3 CONTROLS AND CONNECTIONS 5 4 3 2 8 7 5 4 3 2 9 6 6 1 FRONT PANEL 1. POWER SWITCH: To turn the unit ON or OFF, press the upper or lower portion of this button. The internal power LED illuminates when the unit is turned "ON". (Caution: Always turn the Crossover ON before the amplifier, and turn it OFF after the amplifier or transients harmful to the speakers may result. ) 2. L/M/H OUTPUT LEVEL CONTROLS: These are used to adjust the output level of each way: LOW, MID and HIGH . LOW CUT BUTTONS FOR LOW WAY: These insert low cut filters in the LOW way of each stereo channel with a 12dB/Octave, 30 Hz HPF to minimize problems from subsonic frequencies in the signal, to suppress hum, and to prevent low frequency speaker resonance. 3. PLEASE READ THIS MANUAL BEFORE OPERATING THIS UNIT Caution : To prevent malfunctioning and/or possible equipment damage: Before plugging the unit into the power source: (1) the voltage selector switch should be set for the correct voltage for your area (115V or 230V) and (2) all equipment connected to the crossover outputs should be turned off or all the inputs turned down. 4. MH CROSSOVER FREQUENCY CONTROLS: These select the crossover frequencies of the MID and HIGH ways. LM CROSSOVER FREQUENCY CONTROLS: These select the crossover frequencies of the LOW and MID ways. PHASE BUTTONS: These allow switching the polarity to invert the signal phase on the MID and HIGH ways. This is done after the output levels are set to correct audible phase problems. Caution: Before pressing the PHASE BUTTON, always lower the outputs of your power amplifiers to avoid possible speaker damage. [. . . ] AC VOLTAGE SELECTOR SWITCH: Before plugging in the power cord, check to see that the unit is set for the proper voltage for your area: ~115V (60Hz) or ~230V (50Hz). If it blows continuously, do not use the unit until it has been serviced by qualified personnel.
