[. . . ] 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. Follow Instructions -- All operating and use instructions should be followed. Water and Moisture -- The product should not be used near water -- for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, near a swimming pool or the like. [. . . ] When using a pair of Velodyne subwoofers in stereo, it is preferable to place each subwoofer near the satellite of the same channel. Depending on the size and type of furnishings in the room, perfect placement may not be possible. Finding the best location within your environment will likely require some experimentation. We suggest you experiment with the location during setup to find what sounds best to you when seated in your typical listening position. Regardless of where you install your Velodyne subwoofer, it must remain in an upright position (woofer facing forward). Using, shipping or storing the subwoofer in any other position for an extended period of time may result in damage to the unit not covered by warranty. Do not place the cabinet next to sources of heat such as furnace registers, radiators, etc. Do not place the unit 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 MicroVee User's Manual 2 I n s ta l l a t i o n Your new Velodyne subwoofer provides for a number of installation options. Read all the installation information below in order to determine which installation option is best suited for your system. Remember to perform all installation procedures with system power turned off to prevent possible damage. Figure 1. This is required in certain installations which route the signal through external processors with a crossover circuit of their own. Simply move the switch to SUBWOOFER DIRECT to disengage the built-in crossover. For all other installations which do not have a separate electronic crossover, we recommend you leave the switch set to INTERNAL X-OVER to provide optimum performance. This will eliminate the MicroVee's crossover from the signal path. . www. velodyne. com MicroVee User's Manual 5 LFE Connection - Option A Figure 2 shows connection from your home theater receiver to the LFE input on the back of your subwoofer. When the subwoofer is installed in this fashion, all of the low frequency information from your "LFE Out" or "Subwoofer Out" on the back of your receiver will pass into your Velodyne subwoofer. This connection is the most common connection method when using your subwoofer with a 5. 1 receiver. Installation Using LFE Line-Level Inputs www. velodyne. com MicroVee User's Manual 6 A Wor d About The Auto On/Off Featur e When using a single channel input (such as a surround sound processor's subwoofer out or LFE), the auto on/off circuit sensitivity will be affected. When one input channel is used instead of two, the unit will see lower signal levels present at the inputs. This may cause the unit to turn off inadvertantly when listening at low volume levels and/or not "wake up" even when signal is present. If this occurs, simply use a "Y" adapter (available from most dealers) to allow your processor's single sub line to be fed into both L&R inputs. This will make the unit turn on at lower signal levels. . www. velodyne. com MicroVee User's Manual 7 Mini-Jack Connection - Option B Figure 3 shows connection from your audio player or gaming console output to the MINI-JACK of your Velodyne subwoofer. [. . . ] If you plan to leave the subwoofer unused for an extended period of time, we recommend that you turn off the master power switch on the rear panel. Protection Circuitry Your new subwoofer is equipped with special protection circuitry to provide maximum performance with greatest reliability. The unit is protected against: 1) Overdriving the speaker or amplifier 2) Overheating the amplifier 3) Excessive drop in power line voltage The first type of protection circuitry which prevents overdriving of the speaker or amplifier operates constantly without being audible under most situations. In some extreme situations (sustained high output levels such as pro sound usage), the unit may shut down momentarily. This indicates the thermal or under-voltage protection circuitry has engaged.
