5. EQUALIZATION USING A DIGITAL SIGNAL PROCESSOR
The SR-F04 is to reproduce high quality sound even without the use of an equalizer.
However, sound quality can be made even clearer and more dynamic with the addition of a TOA digital signal
processor (DSP) set as shown in the table.

6. SAFETY WIRE INSTALLATION
Be sure to always use safety wire when installing speaker
systems.
Note
• A safety wire, eyebolts, and washers are not supplied.
Prepare them separately.
• For the adaptive diameter of the eyebolt, see
"DIMENSIONAL DIAGRAM" on p. 8.
• Prepare the eyebolt with a length of over 25 mm (0.98").
Be sure to follow all instructions regarding safety wire
installation. If not correctly followed, speakers could fall,
potentially resulting in personal injury.
• Use safety wire that is strong enough to suspend the
full weight of the components to be installed.
• Remove a screw on the speaker's rear panel, then
install an eyebolt and washer instead, and also install
an anchor bolt for the safety wire to the wall or ceiling
as shown at right.
• Only install speaker systems in locations capable of
structurally supporting the weight of the speakers and
their mounting brackets.
