VERTICAL BI-AMPLIFIED CONNECTIONS
Vertical bi-amplified connections are made between both pairs of
Gem2 input terminals and two separate power amplifier output
channels. Each speaker is connected to its own power amplifier.
The power amplifiers must be identical. Vertical bi-amplified
connections are shown in Figure 8.
To make vertical bi-amplified connections:
1. Remove the jumper straps identified in Figure 4, page 11.
2. Connect one pair of loudspeaker wires to the high frequency
pair of Gem2 input terminals. Then connect the same pair of
loudspeaker wires to the desired power amplifier output
channel.
3. Connect another pair of loudspeaker wires to the
low-frequency pair of Gem2 input terminals. Then connect
the same pair of loudspeaker wires to a separate output
channel on the same power amplifier.
4. Make sure that all terminals are firmly hand-tightened.

Note
When making vertical bi-amplified connections, both power
amplifiers must receive identical input signals from the associated
preamplifier. A “Y” adaptor is required if the associated preamplifier
does not offer two connectors per output channel. Otherwise, each
power amplifier can be connected to a separate connector for the
same output channel of the preamplifier.
Note
Vertical bi-amplified connections must be made using two identical
power amplifiers.
