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 speaker cabinets
are wired in "Parallel", the total imped-
ance is cut in half and when two speak-
er cabinets are wire is “Series” the total
impedance is the sum of the cabinet’s
individual impedance.
The VX1508 impedance is 8 Ohms.
So, when two VX1508’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 VX1508 to Your
Amplifier
The VX1508 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 VX1508’s rear
jackplate.
Using the EXTENSION Output
The VX1508 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 a VX1508 and a
VX115 using the Extension Output.
Connect the Amplifier Output to the
Input of the first VX1508. Now, connect
the Extension Output to the Input of the
VX115.
