[. . . ] (20) Main Power Switch Press the POWER switch to the ON position to activate the amplifier. If the unit is to be left unused for an extended period of time, move this switch to the OFF position to prolong the life of the amplifier. (21) 115V or 230V Operation Selectable Switch This selectable voltage switch is factory preset for the correct voltage in the geographical region in which the product is sold. To retain full Velodyne warranty coverage, this switch should ONLY be operated by a Velodyne factory authorized service representative during a FULL factory-authorized mains voltage change procedure. Should anyone other than a Velodyne factory authorized service representative attempt to perform a mains voltage change in any way, the warranty for the product will be terminated. In this case, Velodyne assumes no liability for any and all injuries to any persons involved, or for any property damage, whether to the subwoofer or any other property involved or damaged as a result of this unauthorized mains voltage change. SC-602 Amplifier User's Manual . www. velodyne. com 7 R e a r Pa n e l C o n n e c t i o n s -- D e ta i l e d E x p l a n a t i o n The SC-602 amplifier is equipped with both speaker-level and line-level inputs. Use the RCA/Phono type "INPUT" jacks when connecting from a pre-amp, signal processor, or line-level crossover. The "SPEAKER LEVEL INPUT" jacks connect directly to the speaker outputs of an integrated amplifier or receiver. Your amplifier section will notice no additional loading effects when you use these inputs because of their high impedance. Note: Do not use both the RCA/Phono "INPUT" connections and "SPEAKER LEVEL INPUT" connections simultaneously. ABOUT LOW-PASS CROSSOVERS All of the SC-602 amplifier inputs sum the left and right channels together and the resulting signal is passed through an adjustable low-pass crossover before being amplified. The crossover control allows you to adjust the upper limit of the subwoofer's frequency response from 30 to 160 Hz. Remember that the built-in 5-band EQ will help to get the most performance out of your subwoofer no matter where it is placed. Do not place the amplifier next to sources of heat such as furnace registers, radiators, etc. Likewise, do not place the amplifier near sources of excessive moisture, such as evaporative coolers, humidifiers, etc. The power cord should be routed in such a way that it will not be walked on, pinched or compressed in any way that could result in damaging the insulation or wire. . www. velodyne. com SC-602 Amplifier User's Manual 9 Selecting the Subwoofer to be Controlled Your SC-602 amplifier can control the Velodyne SC-602 Series subwoofers as well as generic passive subwoofers. Special internal software settings are designed to maximize performance and reliability depending on the model of subwoofer being controlled, so it is important to match the SC-602 amplifier with the subwoofer it is controlling. The SC-602 amplifier comes with a default setting for the SC-602 IW subwoofer. When the unit is first powered up, the model being controlled is displayed for two seconds on the numeric LED before the display reverts to the volume setting. The subwoofer to be controlled is shown as follows: Model SC-602 IW (In-Wall) SC-602 IF (In-Floor) SC-602 IC (In-Ceiling) Generic Subwoofer LED Display IW IF IC GS Note: Both the IF and the IC settings control the SC-602 In-Floor/In-Ceiling (IF/IC) subwoofer and have identical internal settings. To change the subwoofer to be controlled, first power down the amplifier using the main power switch on the back panel (DO NOT use the power button on the front panel). Then, turn the switch on while depressing any of the buttons on the front panel (crossover up or down, or volume up or down). To change the model, simply push the crossover up or crossover down buttons and the model changes on the LED display. [. . . ] Have all controls on the amplifier (volume, crossover, phase, etc. ) been properly set?If the unit has been running at high levels, one of the protection circuits may be engaged. If the protection circuitry is active, the unit may cycle on and off until operating parameters return to normal. Normal operation should return upon cooling, but you may be required to turn the power off and then on again to reset the unit. [. . . ]
