A Wor d About Subwoofer Placement

Subwoofers operate at extremely low frequencies, which are primarily omni-directional. Keep in mind that frequency response and output level can be drastically influenced by 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. The worst location for a subwoofer is typically far away from any walls, close to the center of your room and near an opening or doorway. Avoid these locations when possible. When using a pair of SC subwoofers in stereo, it is preferable to place each subwoofer by the satellite of the same channel. 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 7 band EQ will help to get the most performance out of your subwoofer no matter where it is placed.

Caution!

This amplifier has electronics built into the cabinet. 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.

Selecting the Subwoofer(s) to be Controlled

Your SC-1250 can control a variety of Velodyne SubContractor 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-1250 amplifier with the subwoofer(s) it is controlling. The SC-1250 comes with a default setting for the SC-10 subwoofer. When the unit is first powered up, the model being controlled is displayed for 2 seconds on the numeric LED before the display reverts to the volume setting. The subwoofer to be controlled is shown as follows:

**- The generic subwoofer setting is for passive subwoofers not on the above list. CAUTION: there is no anti- clipping or anti-distortion protection on this setting.

To change the subwoofer to be controlled, first power down the amplifier using the 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). The unit will show the model

it is currently controlling. To change the model, simply push the crossover up or crossover down buttons and

the model changes on the LED display. Once the desired model is seen on the LED display, simply release the

button. You don’t need to do anything else - the model to be controlled is automatically stored in the SC-1250’s
