the instruction manual well to select the proper setting and connection.
1. Remove the ignition key and disconnect the negative - terminal of the battery to prevent
short circuits.
2. Set the unit according to the intended usage.
3. Connect the input and output cables of the units.
4. Connect the speaker cables and sigma servo feed back cables.
5. Connect the power cable, power control cable and grounding cable following this order.
6. Install the unit in the car.
7. Connect the negative - terminal of the battery.
· If sound is not output normally, immediately turn power off and check connections.
· Be sure to turn the power off before changing the setting of any switch.
· If the fuse blows, check cables for shorts, then replace the fuse with one of the same rating.
· Check that no unconnected cables or connectors are touching the car body. Do not remove
caps from unconnected cables or connectors to prevent short circuits.
· Connect the speaker cables to appropriate speaker connectors separately. Sharing the
negative cable of the speaker or grounding speaker cables to the metal body of the car can
cause this unit to fail.
· After installation, check that the brake lamps, winkers, and wipers work properly.
2CAUTION
Installation
· Since the power amplifier has no parts which require operation, it can be installed at a position
away from the driver's seat without any hindrances.
As generally accepted positions for its installation, places such as inside the trunk, etc. can be
considered.

The sound reproduced through conventional amplifiers is distorted due to the counterelectromotive
force produced in the oscillating system of the speaker. The counterelectromotive force is
particularly high with the woofer which requires a large drive mass.The sigma servo connection
reduces distortion caused by the counterelectromotive force by including the circuit up to the
speaker terminals in the negative feedback loop. This makes it possible to drive speakers with
more fidelity to the input signals and create a sharp bass sound image with few feeling of noise
interference.
The aforementioned effects will not be obtained when the sigma servo connection has not been
made.
The speaker cable and the sigma servo cable should be wired to run along the same route. Note
that this wiring should be separated from the power supply cable.
· The SIGMA SERVO FEEDBACK terminals should be connected properly. Failure to connect
them properly will be the cause of breakdown.
· The rated input of the speakers connected to this unit should be no less than the maximum
output of the amplifier. Otherwise malfunction may result.
Be specially careful in this when connecting speakers in a parallel configuration.
· Speakers that are to be used for bridged connections to this unit should have an impedance of
4
or greater. When connecting multiple speakers, ensure that the combined impedance is 4
or greater. Connection of speakers of less than 4
will be the cause of breakdown.
