15-Inch 2-Way Speaker
Your Optimus 15-Inch 2-Way Speaker
is desi
g
ned todeliver uniform sound dis-
persion with excellent sound quality.
Your speaker’s protective corners and
carryin
g
handles make it portable, so
you can use it anywhere you need it. It
is ideal for clubs, schools, churches,
conference rooms, auditoriums, and
other locations that require controlled
sound covera
g
e.
The speaker’s 15-inch woofer and piezo
horn tweeter make it suitable for voice
or music. Its 1/4-inchphone jack and two
terminal posts make it easy to connect
to any amplifier. You can connect two
speakers to an amplifier for stereo
sound.
SPEAKER PLACEMENT
An ideal speaker system covers the lis-
tenin
g
area with a consistent volume
level without reverberation (echo) or
“dead” spots (areas without sound).
To cover a wide area, you mi
g
ht need
one or more additional speakers. If you
use more than one speaker, overlap the
One Speaker Two Speakers
speaker’s projection areas to prevent
dead spots.
CONNECTIONS
Note: Be sure your amplifier is turned
off before you make any wire connec-
tions.

Speakerwire hastwo individual conduc-
tors (wires) covered with insulation, and
is often marked to help you make the
proper connections. Insulation on one
side of the wire mi
g
ht have a rid
g
e or
colored stripe. Or, the two conductors
mi
g
ht be different colors (silver and cop-
per, for example).
For the best bass response, be sure to
connect + on the speaker to + on the
amp, and – on the speaker to – on the
amp.
1. Separate the conductors at each
end for about two inches, then strip
1/2inch of insulation from the end
of each conductor.
2. Unscrew the speaker’s positive (+)
terminal and insert a conductor’s
stripped end into the hole on the
side of the terminal post.
3. Hand ti
g
hten the terminal to secure
the wire in place.
4. Connect the conductor’s other
stripped end to the amplifier’s posi-
tive (+) terminal.
5. Repeat Steps 2–5 to connect the
speaker to the amplifier’s ne
g
ative
(–) terminals.
Using the Speaker’s Phone
Jack
If your amplifier has an 8-ohm phone
jack, use a speaker cable that has a
phone plu
g
on each end (such as Ra-
dioShack Cat. No. 42-2470) to connect
the speaker’s 1/4-inch phone jack to the
amplifier’s phone jack. Or, if your ampli-
fier does not have an 8-ohm phone jack,
use speaker wire that has a phone plu
g
on one end to connect the speaker’s 1/4-
inch phone jack to the amplifier’s termi-
nals.

Connecting Two Speakers to
a Monaural Amplifier
You can connect a second speaker to
cover a wider listening area.The speak-
er puts an 8-ohm load on the amplifier.
If you connect a second speaker in se-
ries, the load increases to 16 ohms. If
you connect a second speaker in paral-
lel, the load decreases to 4 ohms.
Check your amplifier’s specifications to
see which connection to use.
