4Ω (ohms) or 8Ω (ohms) connection to match the
impedance of the Loudspeaker, being careful to
observe the correct polarities.
Note: The illustration in figure 5 is connections for

If the Loudspeaker's impedance is in-between
the available connections, use the nearest lower

Output Terminals and How to Connect

Output Terminal indentified as 2Ω (ohms), 4Ω
(ohms) or 8Ω (ohms) connection to match the
impedance of the Loudspeaker, being careful to
observe the correct polarities. Insert the spade lug
connector or prepared section of the cable end into
the terminal side access hole, and tighten the ter-
minal cap until the cable is firmly clamped into the
terminals so the lugs or wire cannot slip out. Refer
to fgures 7
and 8.

If the Loudspeaker's impedance is in-between
the available connections, use the nearest lower
impedance connection. Refer to "General Informa-
tion" Note 4 on page 3 for additional information.
