2-Channel Mode With 2-Channel Output
This setup is recommended if your subwoofer will be used in a
Signal Connection (see figure 11):
1 Connect the left out/right out from your preamplifier to the Left In/Right In of the subwoofer. Use quality RCA interconnects.
2 | Connect the Left Out/Right Out of your subwoofer to |
|
|
| the left in/right in of your amplifier. Use quality RCA |
|
|
|
|
| |
| interconnects. |
|
|
Recommended Control Settings: |
|
| |
1 | Set the controls as recommended on page 9. |
|
|
2. | The High Pass Filter: Out switch should be set, at the |
|
|
| user’s discretion, to the option with the best sound- |
|
|
| ing result. As a general rule, if your main loudspeakers |
|
|
| are bookshelf speakers, set the High Pass Filter: Out to |
|
|
| 70Hz. Likewise, 40Hz for floorstanding loudspeakers. |
|
|
| Use ‘None’, if you want to pass an unaltered signal. |
|
|
3 | At this time the Low Pass Filter should be set to |
|
|
| approximately 70% of your main loudspeakers lowest |
|
|
| frequency |
|
|
| If the High Pass Filter: Out is set to ‘None’, the Low |
|
|
| Pass Filter should remain at approximately 70% of your |
|
|
| loudspeakers lowest frequency response. |
|
|
| If the High Pass Filter: Out is set to 40Hz, the Low Pass |
|
|
| Filter should be set to 35Hz or 70%, whichever is greater. |
|
|
| If the High Pass Filter: Out is set to ‘70Hz’, the Low Pass |
|
|
| Figure 11. Signal connection for | ||
| Filter should be set to 55Hz or 70%, whichever is greater. |
|

Why the Filters Are Not Equal
You may have noticed the recommended setting proce- |
|
dure does not advise setting the Low Pass Filter and High |
|
Pass Filter: Out to the same frequency. Between 20Hz |
|
and 100Hz, as the subwoofers output decreases, the |
|
loudspeakers output increases. For a seamless crossover |
|
of these two slopes, the summation of their two values, at |
|
any given frequency, should add to maintain a level out- |
|
put. By correctly setting your High Pass Out and Low Pass |
|
filters, this result can easily be achieved (see figure 12). | Figure 12. |
