HORIZONTAL BI-AMPED CONNECTIONS
CAUTION: Remove the shorting straps before making bi-amped
connections. Failure to do so may cause damage to some power
amplifiers.
The two power amplifiers can be identical or non-identical, but they must
have identical gain factors. If their gain factors are not identical, at least one
of the amplifiers must have a means of adjusting its input level. Contact your
authorized Revel dealer for assistance.
Horizontal bi-amped connections are made between both pairs of F228Be input
terminals and two separate output channels of two separate power amplifiers.
The F228Be’s set of high-frequency input terminals is connected to one power
amplifier, while the F228Be’s set of low-frequency input terminals is connected
to the other power amplifier.
NOTE: When making horizontal bi-amped connections, both power
amplifiers 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 the desired
output channel on another power amplifier.
4. Repeat step 2 to connect the high frequency set of input terminals on
the second F228Be to the other channel of the power amplifier that was
connected in step 2.
5. Repeat step 3 to connect the low-frequency set of input terminals on
the second F228Be to the other channel of the power amplifier that was
connected in step 3.
6. Connect the left and right channel inputs of the high-frequency amplifier to
the preamplifier’s left and right outputs. Repeat for the left and right inputs
of the low-frequency amplifier. If the preamplifier only has one connector for
each channel, use “Y”- adaptors.
