VANDERSTEEN 3A - VERTICAL BI-AMP CONNECTIONS

This connection method can only
be used in a system configured with
two identical stereo amplifiers.
Bare wires should never come into
contact with the aluminum dress
plate while the amplifier is on.
Amplifier damage could result.
The input screws should be snug,
but should not be overtightened.
Vertical Bi-Amp Connections
Vertical Bi-amplification uses a stereo amplifier to
drive each speaker. Four identical runs of equal length
speaker cables are required. (Two per speaker.)
1. Connect two cables to each speaker as described in
steps 1-3 on the previous page.
2. Designate one stereo amplifier as the left channel
amplifier and the other identical stereo amplifier as
the right channel amplifier.
3. Use high quality single female to dual male “Y”
connectors to connect the preamp’s left channel
output to both inputs of the left amplifier and the
preamp’s right channel output to both inputs of the
right amplifier as shown in the diagram.
4. Connect the bass cable from the left speaker to one
output channel of the left amplifier and the
tweeter/midrange cable from the left speaker to the
other output channel of the same amplifier.
5. Connect the bass cable from the right speaker to
one output channel of the right amplifier and the
tweeter/midrange cable from the right speaker to the
other output channel of the same amplifier.
For Better Sound
a. Verify with the amplifier manufacturer that your amp¬
lifiers are the same generation and sound the same.
b. If your amplifiers have multiple impedance taps, both
cables should be connected to the same rated taps.
c. All four speaker cables should be the same type and
length. While certain different cable types may
work well together, using identical cables on the top
and bottom insures perfect blending.
