SPEAKER CONNECTION

The unit has provision for two pairs of speaker systems—system A and system B—which can be selected individually or simultaneously by means of the front panel SPEAKERS select buttons.

Note that the speaker systems A and B are series-connected. Connect the second speaker system to the SPEAKER B inputs.

No sound will be heard if only one of the speaker systems is connected and the SPEAKERS select buttons A and B are depressed.

Speaker impedance and power capacity

This amplifier is designed to work best with speakers having nominal impedance from 8 to 16 ohms, and rated at 32 watts minimum RMS per channel with an 8-ohm load from 40 – 20,000 Hz. Be sure not to use speakers with impedance less than 8 ohms and to use adequate power handling capabilities.

Speaker cord connection

1 Strip the outer covering and twist the wires.

2 Keep the terminal button depressed and fully insert the wires into the slot, and then release the button. Pull on the speaker cord lightly to see if the connection is secure.

Right speaker cord Left speaker cord

Generally speaker cords are coded with color, or mark, indicating the ⊕ ⊖ polarities. Remember the coding and prevent faulty connections.

Right speaker: to R'SPEAKER terminals

Left speaker: to L SPEAKER terminals

⊕ code: for ⊕ connection

⊖ code: for ⊖ connection

Speaker placement

Here are a few suggestions on basic speaker placement.

— Place each speaker with its back 3—5 cm (1 ^1/4 -2") from a hard wall in a similar acoustic environment.

— Set your speaker system up on a hard, flat floor or pedestals. Carpets, draperies and upholstered furniture will minimize the multiple reflections of high-frequency sound which reduce the stereo effect.

— Generally we recommend that the speaker/listener relationship be an equilateral triangle. If the speaker separation is too wide, face the speakers a little towards each other.

Wall Left speaker 50°~60° Right speaker Best listening position

— Place the speakers no higher than your ears when you are seated, if the speakers are to be positioned above the floor.

AC OUTLETS

These are used to power other audio components whose total power consumption is less than the indicated wattage.

The SWITCHED outlets are controlled by the front panel POWER switch.

The UNSWITCHED outlet is not controlled by the POWER switch.

Do not connect any electrical home appliance such as an electric iron, fan, TV or other high-wattage equipment to these ac outlets.
