8. Voltage Selector Switch: The subwoofer ampliﬁer can be used on 110~120V (60Hz) or

220~240V (50 Hz) line voltage. To change the operating line voltage, turn the power

off using the power switch and unplug the power cord. Remove the plastic cover screws

and the plastic cover over the voltage selector located on the rear of the subwoofer

ampliﬁer. Set the switch to the correct position for the line voltage in your country.

Replace the plastic cover and screws over the voltage selector switch.

NOTE: If required, remove the IEC line cord and replace with an IEC AC cable that

matches the AC wall socket, this should be a 10A rated cable. When the voltage selector

switch is changed, the fuse must also be changed to continue to provide protection

to the ampliﬁer.

9. Power Cord Receptacle: The supplied power cord needs to be connected to this

receptacle in order for the Subwoofer Ampliﬁer to work properly.

WARNING! Make certain that you are using the proper power cord and voltage selection

for the type of AC power supplied in your country.

10. Fuse Holder: This is the power fuse access.

WARNING! In the event the fuse must be replaced, the replacement fuse must

match exactly the original fuse value. If the replacement fuse is not of the same

value, damage to the Subwoofer Ampliﬁer may result. Use a GDA type fuse for the

SA-250DSP: 5A 120V or 2.5A 240V fuse, and for the SA-500DSP use a 8A 120V

or 4A 240V fuse.

CAUTION! Before replacing the fuse, disconnect the power cord from the power

receptacle.

11. Removable Feet: The ampliﬁer feet can be removed as required for rack mount

installation.
