Connecting the 1800
About Impedance
Before you hook up your speaker cabinet, be sure that you understand a little abou
impedance. Impedance is the electronic load that the speaker puts on the power amplifie
and is measured in Ohms.
Here is the tricky, yet simple rule of impedance: When two speakers are wired in "Paralle
the total impedance is cut in half and when two speakers are wire in “Series” the tota
impedance is the sum of the speakers individual impedance.
The
1800
impedance (many audio
guys used the made up word “ohmage”
however the correct term is impedance)
is 4 Ohms. So, when two 1800ʼs are
connected together in parallel, the tota
impedance is 2 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
manufacturerʼs recommended imped-
ance for your amplifier to avoid any
damage to your amplifier or voiding
your warranty.
Connecting the 1800 to Your Amplifier
The 1800 connections are made via
1/4” phone jacks located on the rea
panel jack-plate. Be sure to make you
connection with un-shielded speaker
cable. Connect the Amplifier Output to
the speaker Input on the 1800ʼs rear
jackplate.
Using the EXTENSION Output
The 1800 provides both 1/4-inch and
Speakon connections. You can use
either connector to connect to your
amplifier head. Since both the 1/4-
inch phone and Speakon connectors
are wired in parallel, you can connect
additional speaker cabinets using eithe
connector as an extension output. Be
sure to read the section above on
impedance to insure a proper hook-up
with your amplifier.
