NOTE: ADDITIONAL SPEAKERS MAY BE INCLUDED IN SERIES, BUT IT IS NECESSARY TO CALCULATE TOTAL IMPEDANCE, AND CONNECT THE SPEAKER CIRCUIT TO A TERMINAL OF APPROPRIATE IMPEDANCE. FOR EXAMPLE, IF THREE SPEAKERS OF 4-OHM ARE USED, TOAL IMPEDANCE IS 12 OHMS, YOU SHOULD CONNECT TO THE 16-OHM TERMINAL. System 3:Two (or more) speakers in parallel 1.Connect the LEFT SPEAKER (-) to the RIGHT SPEAKER (-). 2.Connect BOTH the LEFT SPEAKER (-) and the RIGHT SPEAKER (-) to the amplifier COMMON terminal. 3.Connect the LEFT SPEAKER (+) to the RIGHT SPEAKER (+). 4.Connect BOTH the LEFT SPEAKER (+) and RIGHT SPEAKER (+) to the amplifier 4-Ohm, 8-Ohm or 16Ohm terminal, depending on the TOTAL IMPEDANCE of the two speakers. If each speaker has an impedance of 8-Ohm, the total speaker impedance in this parellel configuration is 4 Ohms. 4.Connect the speakers' (-) terminals to the amplifier's COMMON terminal. 5.Connect the speakers' (+) terminals to the amplifier's 4-Ohm, 8-Ohm, or 16-Ohm terminal, depending on the TOTAL IMPEDANCE of the FOUR SPEAKERS.

Simply be sure you have properly calculated the total impedance, and connect the (+) speaker circuit wire to the proper amp terminal. For example, if you use a SERIES PAIR of 8-Ohms speakers (the total impedance is 16 ohms) and a PARALLEL PAIR of 8-Ohms speakers (the total impedance is 4 ohms) in a PARALLEL hook up, the TOTAL IMPEDANCE of this system is 3.2 OHMS, so you should connect the (+) speaker circuit wire to the 4OHM terminal. connection described above is also 8 ohms. Likewise, the total speaker impedance is 4 or 16 ohms, if the speakers are 4 or 16 ohms respectively. 5

NOTE:
ADDITIONAL SPEAKERS MAY BE INCLUDED IN
SERIES, BUT IT IS NECESSARY TO CALCULATE TOTAL
IMPEDANCE, AND CONNECT THE SPEAKER CIRCUIT
TO A TERMINAL OF APPROPRIATE IMPEDANCE. FOR
EXAMPLE, IF THREE SPEAKERS OF 4-OHM ARE USED,
TOAL IMPEDANCE IS 12 OHMS, YOU SHOULD
CONNECT TO THE 16-OHM TERMINAL.
System 3:Two (or more) speakers in parallel
1.Connect the LEFT SPEAKER (-) to the RIGHT SPEAKER
(-).
2.Connect BOTH the LEFT SPEAKER (-) and the RIGHT
SPEAKER (-) to the amplifier COMMON terminal.
3.Connect the LEFT SPEAKER (+) to the RIGHT
SPEAKER (+).
4.Connect BOTH the LEFT SPEAKER (+) and RIGHT
SPEAKER (+) to the amplifier 4-Ohm, 8-Ohm or 16-
Ohm terminal, depending on the TOTAL IMPEDANCE
of the two speakers. If each speaker has an
impedance of 8-Ohm, the total speaker impedance
in this parellel configuration is 4 Ohms.
4.Connect the speakers' (-) terminals to the amplifier's
COMMON terminal.
5.Connect the speakers' (+) terminals to the amplifier's
4-Ohm, 8-Ohm, or 16-Ohm terminal, depending on
the TOTAL IMPEDANCE of the FOUR SPEAKERS.

SERIES/PARALLEL VARIATIONS
Although the description above is for combining TWO
SERIES PAIRS in a PARALLEL hook up, you may also
select to combine a SERIES PAIR and a PARALLEL PAIR
in a PARALLEL hook up. Simply be sure you have
properly calculated the total impedance, and connect
the (+) speaker circuit wire to the proper amp terminal.
For example, if you use a SERIES PAIR of 8-Ohms
speakers (the total impedance is 16 ohms) and a
PARALLEL PAIR of 8-Ohms speakers (the total
impedance is 4 ohms) in a PARALLEL hook up, the
TOTAL IMPEDANCE of this system is 3.2 OHMS, so you
should connect the (+) speaker circuit wire to the 4-
OHM terminal.
System 4:Four speakers in series/parallel
combination
1.Group the four speakers into two pairs.
2.Connect each pair of speakers in SERIES (see system
2 above).
If you connect 8-ohm speakers, the total impedance
of each pair is 16 ohms.
3.Connect the two pairs of speakers in PARALLEL, If
you connect 8-ohm speakers, the total impedance
of both pairs is 8 ohms.
Note:If each of the four speakers is 8 ohms, the total
speaker impedance of the combined series/parallel
connection described above is also 8 ohms. Likewise,
the total speaker impedance is 4 or 16 ohms, if the
speakers are 4 or 16 ohms respectively.
