Note

Set the LOW FILTER switch to ON when you connect an active woofer. This cuts low frequency output from the front speakers so you can enjoy pure bass from the active woofer.

If you have an additional front speaker system

Connect them to the FRONT SPEAKERS B terminals.

If your TV monitor uses separate speakers

You can connect one of them to the SURROUND OUT CENTER terminal for use with Dolby Pro Logic Surround Sound (see page 18).

Set the IMPEDANCE SELECTOR for the front speakers as indicated in the table below. Check the instruction manual of your speakers if you’re not sure of the impedance. (This information is usually printed on a label on the back of the speaker.)

Getting Started

Selecting the speaker system

If you connect only one set of front speakers, set the SPEAKERS selector on the front panel to A. If you connect two sets of front speakers, see the following:

*Connect speakers with nominal impedances of 8 ohms, or higher, to the A and B terminals. You don’t have to switch the impedance selector, since it switches to 4 ohms automatically.

For even more powerful amplification

You can use the POWER SWAP function to connect two additional amplifiers.

1Unplug the power cord.
