Line-level connection

Figure 1 shows connection to a pre-amplifier's main outputs and returning them to your amplifier inputs.

When installed in this fashion, your satellite speakers will be crossed over at 85Hz which removes the lower bass from your amplifier and speakers, enabling them to do a better job reproduc- ing high frequencies. By utilizing this method, you will have a bi- amplified system, gaining improved power and headroom for your system.

A word about subwoofer outputs

The Velodyne subwoofer is designed to operate using the full range audio signal for input when using the built-in crossover. Some surround sound processors/receivers, including the Dolby AC3 system with their .1 channel output, have a "subwoofer out" jack that

mance you should bypass the internal crossover in your Velodyne subwoofer, the Subwoofer Direct feature.

To bypass the crossover within the subwoofer, simply locate the switch marked "out / in" on the back panel of the subwoofer and set to the "out" position. This will eliminate the internal crossover function.

Note

If not using an external crossover, you should use the built-in crossover for optimal performance.

Figure 2 shows an easy way to connect your VA-907.2 subwoofer directly to your receiver or integrated amplifier.

When connected in this fashion, your satellite speakers will be crossed over at 85 Hz, which removes the lower bass from your speakers thus, enabling them to do a better job reproducing high frequencies.

You may also connect your satellites directly to your receiver or amplifier along with the subwoofer if you wish to bypass the internal high-pass crossover.

Caution!

To avoid damage to your main amplifier, be sure to maintain correct polarity when making all connections. Red (positive) to red, and black (negative) to black. Be sure that all connections are tight, and that there are no loose strands or frayed wires.
