VERTICAL BI-AMPED CONNECTIONS

CAUTION: Remove the shorting straps before making bi- amped

connections. Failure to do so may cause damage to some power

ampliﬁers.

Vertical bi-amped connections are made between both pairs of F208 input

terminals and two separate output channels of a single power ampliﬁer. Each

F208 loudspeaker is connected to an individual power ampliﬁer, which can

sometimes increase sonic performance. The power ampliﬁers for the two

loudspeakers must be identical.

NOTE:

• Vertical bi-amped connections must be made using two identical power

ampliﬁers, one for each loudspeaker.

• When making vertical bi-amped connections, both power ampliﬁer

channels must receive identical input signals from the associated

preampliﬁer. If the associated preampliﬁer does not have two output

connectors for each channel, “Y” adaptors are required.

1. Remove the shorting straps.

2. Connect one speaker cable to the high frequency set of F228Be input

terminals. Then connect the other end of that speaker cable to the desired

power ampliﬁer output channel.

3. Connect another speaker cable to the low-frequency set of F228Be input

terminals. Then connect the other end of that speaker cable to another

output channel of the same power ampliﬁer you connected to the high-

frequency input terminals.

4. Connect both ampliﬁer channel inputs to the output of a single preampliﬁer

channel. If the preamp only has one connector for the channel, use a “Y”-

adaptor.

5. Repeat steps 1, 2 and 3 to connect the second F228Be to another, identical

power ampliﬁer. Repeat step 4 to connect the second ampliﬁer to the

preampliﬁer’s other channel.
