Line Level Input Signal Connection (figure 3):

Connect the left and right line level outputs of your pream- plifier to the left and right 'Line Level Input' connections of the Dynamo 300 using quality RCA interconnects. If your preamplifier only has one set of outputs you may need to obtain Y adapters from your dealer.

Speaker Level Input Signal Connection (figure 4):

Connect the left and right outputs of your amplifier to the subwoofer’s left and right 'Speaker Level Input' binding posts. Use quality speaker cable.

If your amplifier only has one set of outputs you may connect your amplifier to your speakers as normal and run an additional set of cables from your speakers to the subwoofer’s 'Speaker Level Input' binding posts.

It is also possible to connect the left and right outputs of your amp to the left and right 'Speaker Level Input' of the subwoofer and run additional cables from your subwoofer to the speakers.

Recommended Control Settings (see figure 2):

1Set the 'Low Pass Filter' knob to approximately 70% of your loudspeakers lowest frequency response.

3While playing music with bass content, turn the 'Level' control up until the music has deep extended bass, being careful to avoid levels that become overwhelming.

4Try the 'Phase' control in different settings until the best blending is obtained.

Multi-Channel/LFE Mode

This setup is recommended if your Dynamo 300 will be used in a dedicated home theater or multi-channel system. When a signal is connected to the subwoofer’s LFE input, and the crossover switch is set to 'Bypass (LFE In)' the internal low pass filter is not active. By following this setup, you will allow your processor to handle most of the bass management.

If you will be using your system for both 2-channel and multi-channel listening we recommend using this setup

and connection method. Some modern receivers and processors allow users to route left and right channel low-frequency information, in addition to discrete LFE infor- mation, through the LFE output.

Figure 6. For Multi-channel/LFE mode set the Low-Pass Filter at 150Hz. Adjust Level and Phase controls.
