DOTTED LINES SHOW 4-SPEAKER CONNECTIONS.
IN THIS CASE, IT IS BETTER TO USE 4 ohm SPEAKER TO
PREVENT ANY DAMAGES.
Fig. 4 Speaker Output Connections—MONO Mode
•
The amplifier can be used in the STEREO and BRIDGED mode as shown in Fig. 4, Fig. 5.
•
The speaker wires should be connected to the speaker terminal on amplifier.
•
Notice that most speakers have a polarity marking such as “+” or a dot on speaker terminals and
these markings denote the positive terminals of the speaker and are used as a guide to phase the
speakers. Improper phasing causes a loss of bass response.
•
When used in the BRIDGED mode the speaker wires should be connected to the output terminals
of the amplifier as shown . (Ref. To Fig. 5)
•
When operating 4-speaker system, the impedance of the speaker is an important factor. Do not use
less than 2 ohm in the mono mode.
•
Do not use speakers in parallel for less than a 1 ohm load per channel in the stereo mode.
•
Too low impedance loads will cause excessive heat radiation from the amplifier and the protection
circuit will be operated to prevent damage. In this case, you must reduce the volume to the proper
level.
Caution
Be careful not to connect speaker (-) to the ground chassis .
