[. . . ] The exclamation point symbol is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the subwoofer. Read Instructions -- All safety and operating instructions should be read before the product is operated. Retain Instructions -- The safety and operating instructions should be retained for future reference. Heed Warnings -- All warnings on the product and in the operating instructions should be adhered to. [. . . ] (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.

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. Keep in mind that frequency response and output level can be drastically influenced by room placement, depending on the acoustic properties of the listening room. Typically, the optimum location for a subwoofer is in a front corner of your listening room. This location will usually offer the greatest output levels and optimum low frequency extension. Typically, a minimum distance of one to two feet from your TV to the subwoofer will be adequate to avoid any magnetic interference. 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.
