About Impedance
Before you hook up your speaker cabinet, be sure that you understand a little about
impedance. Impedance is the electronic load that the speaker puts on the power amplifier
and is measured in Ohms.
Here is the tricky, yet simple rule of impedance: When two speakers are wired in "Parallel"
the total impedance is cut in half and
when two speakers are wire is “Series”
the total impedance is the sum of the
speakers individual impedance.
The VX115 impedance (many audio
guys used the made up word “ohmage”,
however the correct term is impedance)
is 8 Ohms. So, when two VX115’s are
connected together in parallel, the total
impedance is 4 Ohms. The impedance
of your speaker also has an effect on
your amplifier. In general, the lower the
impedance, the more power your ampli-
fier will put out.
IMPORTANT
: There is a minimum safe
impedance so be sure to check the
manufacturer’s recommended imped-
ance for your amplifier to avoid any
damage to your amplifier or voiding
your warranty.
Connecting the VX115 to Your Amplifier
The VX115 connections are made via
1/4” phone jacks located on the rear
panel jack-plate. Be sure to make your
connection with un-shielded speaker
cable. Connect the Amplifier Output to
the speaker Input on the VX115’s rear
jackplate.
Using the EXTENSION Output
The VX115 provides a convenient
Extension Output for connecting addi-
tional speaker cabinets in parallel. Be
sure to read the section above on
impedance to insure a proper hook-up
with your amplifier. Follow the steps
below to connect two VX115’s using the
Extension Output. Connect the
Amplifier Output to the Input of the first
VX115. Now, connect the Extension
Output to the Input of the second
VX115.
