Speakers

For Direct 8-ohm Operation:

Use speakers of proper voice coil impedance and power handling capability.

For 25 V/70 V Line Operation:

When using the amplifier's 25 V or 70 V line operation, the tap setting on the proper V-matched line-

matching transformer determines the individual speaker's power level. Use of these transformers allows

the speakers to be placed at longer distances from the amplifier without significant power loss. The

number of speakers for a line-driven central amplifier system is limited to the power available from the

amplifier.

Note: The sum of all of the connected speakers' power settings MUST NOT exceed the total power

available from the amplifier.

Example: This 250-watt central amplifier can drive approximately 33 speakers with drivers tapped at 7.5

watts each.
